/diy/ - Do It Yourself

>>1631854
I want a compact impact drive I can use to break rusty hard to reach bolts on my car. I don't have an air compressor and I don't want to spend $300 on one.
I'd buy a corded electric impact driver but they are way too large and wouldnt fit on anything.
is there anything like a compact air impact that uses electric?

hey /diy/, /fit/owg/ (olympic weightlifting general) here. I'd like to set up a lifting area in my backyard. I'm going to create waterproof cases for my weight plates and barbell, but I'm wondering: can I lift in the rain, or will it mess up the barbell's bearings (bearings are VERY important in /owg/). Would I be fine with just lubing them up after rain (or would WD40 then lube be a better idea?)?

I've got a little push lawn mower, and my dumbass hit one of the metal covers over the water line in my yard.

The mower still runs, but it's shaking like fucking crazy. You lads reckon I belt the shaft? Would I be better off just buying a new mower?

>>1632832
>You lads reckon I belt the shaft?

Look at the blade first.

>>1632873

I ended up taking the blade off, smacking the crank shaft with a hammer a couple times and it seems to be working fine lel

Hey /diy/ I’m currently planning my PhD in synthetic biology and would like to get a better understanding in logic/circuit design before I begin designing anything of my own. I know the basics but wouldn’t call it any more exhaustive than a YouTube video or Wikipedia article. Are there any resources/books you’d recommend? Pics are similar to what I’m trying to build.

>>1632970
I’m attempting to design a novel open genetic circuit platform for use in photosynthetic organisms. I’m trying to apply it in a similar way to the bottom left in this pic.

What is a good/sufficient work bench for an apartment in a 12 unit building? What's the minimum sturdiest bench I can have for sawing wood on, clamping down board and using circular saw on, etc?

Home Depot might still have the M12 stuff on sale. I doubt that stubby impact will be on there, but you could get the M12 Fuel set and that little 1/4” driver will break loose anything under 1/2”, then you get a free tool so grab the ratchet and buy yourself the 3/8” M12 Fuel anon posted.

Alternatively, 18v 1/4” hex impact drivers are becoming stupid powerful if you get the brushless models. Pic related, this Gen 5X Ridgid will break loose 100ft-lb lugnuts, and their newest Octane model is rated even higher. It’s only about 6” long. The mid torque 1/2” models aren’t all that large either.

I have a $25 Amazon gift card. What should I buy? I was thinking the babby 5” or 6” Cobras. I really want the smaller Pliers Wrench but don’t feel like spending $50 on it right now.

Other options are some of those long driver bits, the ones that taper for most of the ~6” shaft so you can actually fit a T10 into a recess. Or some of those Engineer jappo screw removal pliers.

I've got some old binoculars that were a gift to me, they have some sentimental value. Unfortunately their size and weight makes them quite hard to use yet they lack a tripod mount. Does anyone have any ideas for a simple mounting technique that isn't destructive to the binoculars themselves?

They are quite high power so this combined with their weight and length makes it very difficult to hold an image. I have a tripod already but as stated, no way of connecting the two.

I have included as good a view of the binoculars themselves as I could readily provide.

I found some old locks from my lockers back in school. Given that I graduated 6+ years ago, I haven't unlocked them since. I was able to decode the master lock, but anyone know ways of decoding the brinks lock? I can't seem to find anything on it.

I bought an electric air pump, but out of desperate need I didn't realize it can only be plugged in to a car ac. I can just haul my motorcycle over to my car, but for future convenience, does anyone know a proper adapter I'd be able to use for this? I imagine an adapter with more watt capability, more likelihood of it being able to power the inflator.

I inherited my grandfather's old pocket knife. One of the springs that hold the tools open is broken. Is this something that can be fixed?

Really stupid question here. My main beefy computer is in my office. I would like to play games on the tv in my living room with minimal latency. I am of the understanding that long hdmi cords lose signal quickly and as such are not a good solution. Is there a way to play games on the TV in my living room without moving my entire computer? Would it be easier to just make a smaller PC for the living room?

>>1633575
How long are we talking about here? I relied on a 10 footer and didn't experience any latency loss. Alternatively you could consider a steam link when they go for like 90% off during major sales.

>>1633582
About 35 feet.

>>1633575
You just missed
>>1627432

Not him but I personally haven't had a problem with steam link. Well no, I've had lots of problems with steam link but not any more than any other PC gaming experience. Its performance is okay. Samsung also has it built into their new tvs.

I also dont play so online anymore. But single playerit's fine, even for something pretty hard like la mulana, or dead cells.

>>1633533
Can you do lost?

>>1633584
Most HDMI cables start losing their quality at about 50 feet. So you should be good. Only problem really would be finding one at that length and the price. Shorter is always better if you can makes it sub 30 feet.

Just bought a house with galvanized pipe, water pressure is fine no sediment in the water, is it worth it to replace or should I wait until there’s an issue? Or replace pipes I have easy access to?

Also saddle valve on galvanized pipe, am I asking for a leak?

>>1633585
Thanks for the link to what I just missed. On the note of the steam link, I have a samsung tv with steamlink built in, and a physical one. I seem to get better latency out of using the one built into the tv oddly enough, which creates the issue of my tv not letting controllers connect through Bluetooth. The steam controller connects but I would prefer to use a ps4 one. The steamlink feature is what I currently use to play my gamnes out there right now.

Is this a natural gas furnace?

>>1633597
You can also get cat5/6 hdmi converters (you wire them directly together, it's not an ethernet thing) I dunno if it affects lag.

You can also get optical hdmi for long distances

As long as whatever hdmi you're getting is rated for whatever version of hdmi you're using, it should be okay.

Just general curiosity, why do some engines have "jumpy" RPM when idling? As in the RPM goes up and down in a relatively constant manner

>>1633639
they sell that flexible yellow tubing at big box stores and market it for gas, but with out more detail, like a model number or look at the electrical box it is tough to answer

>>1633674
>As in the RPM goes up and down in a relatively constant manner

Probably a control loop that has a lot of hysteresis or some other lag, and could be normal behavior. Meaning, it checks something, like the oxygen sensor, and if it's too high it adjusts the air-fuel ratio, and waits for it to go somewhat lower to re-adjust.

If it's going up and down a lot something might be misbehaving.

>>1633561
The bike has a 12V battery to start it, right? I kept blowing fuses using the cig lighter with my little air pump so I cut the plug off and put a couple battery clamps on there so now I hook it straight to the battery. Just make sure the bike is running when you do it because you will drain the thing really quick with those pumps.

what should I set these minifridge dials to?

>>1634056

Those are shitposting alarms. the 1-7 is a daily alarm, and the 24 is an hourly alarm. Your's seem to be working fine as they are.

>>1634060
sorry. someone refered me to the stupid questions thread in that one.

>>1634063

yah, you're doing fine. If anybody knows they will tell you in all five threads.

>>1633743
Thanks. I guess I'll figure it out when I look at the house next week.

>>1634056
You should set it low then put a cup of water and a thermometer in it. Adjust accordingly to the temp you want.

>>1634167
>set it low

it has two dials. is one for temperature and the other for some sort of defrost schedule? If so, which is which, and what do the markings correspond to. I'm not the actual poster, just curious.

>>1634188
OP here, the 1-7 is standard temp settings for a fridge. I think the 1-24 is for deciding how many hours in between defrosts in the fridge. But I realized after plugging it in the compressor wasnt making any noise at all and the power cord is frayed, so its back to the shop.

How do I adhere a copper cladding to wood?

Will that work for adhering wood to copper.

Posted a couple weeks back. Picrelated is a 2x4 frame to hold an A/C in a horizontal sliding window for an A/C designed for vertical hanging windows. Would like to ask about securing the middle horizontal piece properly. I'm using 3.5" deck screws for everything, but since that middle part would only have deck screws preventing the entire A/C from falling out of a high up window I would like to secure it better.

How can I do that? That is, how can I make sure that middle horizontal 2x4 in the frame is super duper secure and can take a ton of load pushing it out?

>>1634582

Have another tastefully designed 2x4 inside the house wide enough to span the studs outside the window. Then do whatever it takes to secure it to the one on the outside. Long threaded rods would be excellent, with large flat washers, but you should be able to use your deck screws in quantity to make it secure.

>>1634584
Thanks for the reply but I didn't really understand what you mean (can u mspaint it?).

If I get the jist of what you are saying, with the threaded rods why would I need another 2x4 inside the house? At that point could I not just drill a hole through the outside 2x4 and the vertical 2x4s and use a threaded rod there?

>>1634645
>why would I need another 2x4 inside the house? At that point could I not just drill a hole through the outside 2x4 and the vertical 2x4s and use a threaded rod there?

If I understand your drawing correctly, a 2x4 inside the house requires a hole through (2) 2x4s and whatever you close off the upper opening with. If you go through the wall studs you have to drill through your interior wall, the stud, and the exterior siding or whatever is out there, which does not seem like a good idea to me, but yeah, it would eliminate the need for the tastefully designed 2x4 inside your house.

The dummies who wired up my house when it was being built decided to run the same color #12s (all black) from the panel to the j-box for my A/C controls, and then from the bell box on the roof back down to the j-box inside.

If I wanted to replace my manual evap cooler dial switch with a thermostat, are the connections roughly the same as on the dial switch?

>>1634670
>If I wanted to replace my manual evap cooler dial switch with a thermostat, are the connections roughly the same as on the dial switch?

if the dial switch simply closed some contacts and the thermostat simply closes some contacts then it seems like they are interchangeable. And what the fuck is a bell box and a j-box.

How can I use a short screwdriver bit (picrelated) in a drill? The jaws that grab the bit are recessed way inside. Do I have to buy even more fucking shit

>>1634706

also just google bit holder, helps in awkward places and some have magnets to hold screws. you get bendy ones too very helpful.

What pilot hole size should I use for an 8x3 wood screw?

>>1634730
look at the screw in your hand.
look around the middle where there are threads, not at the head or a blank bit and not at the tip where the width changes, look right in the middle where its threads of a constant width.

it has a solid middle core bit and then it has threads that all go around the solid middle core bit.

your pilot hole drill size should be around about the same size as the solid middle core bit. it can be smaller, literally any size is better than nothing. it can't really be bigger. at all. well it can but not great. it definitely can't be bigger than the thread bit or the screw will just fall out.

>>1634730
>>1634734
btw the reason i gave you a wanky answer instead of just a number is because a) now you can work it out for any size wood screwm b) 8x3 means literally nothing, presumably its imperial? inches? who knows you weren't specific at all. if you don't know how to size a pilot hole i'm not going to trust you know what screw sizes are properly.

>>1634706

stupid guy here
When I try to drill stuff (not drive) using a normal drill bit the bit gets pushed back into the clutch jaws. So say I want to drill a 2" hole, I make sure I leave the bit far out enough and tighten the clutch. But then when I go to drill the hole the bit gets pushed back and I can't drill far enough

>>1634734

That's the only real answer anyway because who is gonna go find a table when they can just hold shit up and look at it.

I currently got a job in water restoration when in 6 months I can transfer departments become a apprentice plumber,but I currently am also set to meet up with a union Carpenter to talk about a join where I can become a apprentice of his and make $32 an hour and have gas and hotel allowance. The difficulty is choosing whether to travel far away and do long hours as a carpenter.Or be a local plumber and make extra money be doing jobs under the table since plumbers are in high demand. Should I risk and become a carpenter working hard but get tons of money or stay on the plumber route for east and steady money.Anyone in one of these trades pls give input Im okay with hard work I just hope in carpentry I can have a 30 minute lunch break since I wasnt given it when I used to work on a pipeline.also am a 21 year old zoomer.

I used to work in construction going across the country for projects. I don’t know about carpentry specifically but here’s my two cents. Being a plumber is the ‘safe-reliable’ option. High demand, always work to do. Look into HVAC too. Yes, sometimes you do toilets. Thats the job. You can probably stay fairly local and make decent money. Travelling construction was great money but there were downsides. I was away from home for 3+ months at a time and missing birthdays and smaller holidays. The wife loved that, but you’re young and might not have those types of issues. You’re going to be the low man on the pole when you start, if you can’t learn fast, work fast and do the job right at the same time you’re always going to be the guy humping materials around and doing the dumb work. I’ve fired people that knew their stuff but couldn’t hustle. Like I said the money was great but sometimes theres a month or so that went by in between jobs where I didn’t have a paycheck coming in. Not a huge issue but it did get in the way from time to time.

More a /v/ question but they're useless.

Do adult edutainment games exist?
Something like say electrical wiring has simple underlying rules, a few metrics for determining a job well done, and knowing handyman skills boosts one's self worth.
Thinking about Kerbal Space Program made me realize I can't name any. Throw on enough cartoon graphics and peppy music for popularity and I feel like this could be really big.

How do I know when I need to use a washer for something?

Is it possible to fabricate a hole to make a doorway leading outside in the existing wall of a house? The exterior side of the wall is brick, and it's the same wall that the electrical meter/circuit panel is on (interior side of the wall is obviously sheetrock), so I'm sure there's going to be a risk that there'll be some MC cable or romex running through that wall towards my dining room/kitchen.

I basically want to have/get a door inside my garage that leads to the side of my house where my garbage cans are. Mostly so I can have quicker/easier access to the garbage cans but also so I can air the room out occasionally without having to open the garage door.

>>1635329

A washing machine, or a washer that is used with a bolt? I'm assuming you mean a flat washer, and not a cut washer or a lock washer or a washing machine.

You use a flat washer only when you want to distribute the load over more area. If your bolt fits tightly in a metal hole sometimes you do not need a flat washer. If the hole is a bit loose or the material is soft like wood, then you use a flat washer. They make really large flat washers called "fender washers" that are usually kinda thin but large and are for flimsy stuff like sheet metal.

>>1635345
Yes I meant flat washers. I have two scenarios:
>1/4" Threaded rod going through two pieces of 2x4 and I'm using nuts on each side to hold the 2x4s together. Want to know if I should use washers
>I have 6x1/2" screws that go through two sheets (both relatively thin aluminum or steel, I can't really tell). The screws seem a bit small (ie maybe they should be 8's but 8's seem too big) and I lost the original screws. The screw heads also seem a bit small relative to the holes. Was wondering if I should use washers here as well

Basically, am I really ever making the load bearing or anything worse by using flat washers? I need this all to be extra secure.

>>1634774
You're not tightening the chuck enough.

>>1635252
There's Trucking Simulator, Farming Simulator, etc

>>1635358
Yeah I figured, thanks. It was a double collar chuck (I think that's what its called) so I had to hold one ring while tightning the ring that actually open/closed the jaws. If I didn't hold the first ring in place, it would spin after a certain amount of torque was applied to it so I thought that was the indication that it was tightened enough.

>>1635356
>Basically, am I really ever making the load bearing or anything worse by using flat washers?

I don't think so, but there might be some esoteric mechanical engineering situation where it could. With 2x4 lumber definitely use washers. You might even stack a normal flat washer on top of a fender type. The other scenario also sounds like flat washers would help. And again, if the thin aluminum is extremely thin, you can stack larger washers or even use some thicker aluminum stock and drill a hole through it, to go beneath the ordinary flat washer.

>>1635363

And there are different types of chucks, and some just aren't very good in that they are hard to really tighten. My dewalt drill has one of the best keyless chucks I've ever used, while I have an older makita that is nearly worthless. That's not an endorsement of dewalt over makita in any way. If you're buying a tool, it's nice if you can try it out before purchasing and see how it feels.

I want to make a 2 stroke exhaust because the old one is rusted through. The theory behind it isn't a big problem, but I didn't know making proper cones is black magic.

Copper pipe under a sink in an apartment a friends working on keeps developing a hole.

Put in bucket, add sand, use for dirt removal from landscaping/gardening tools. Just plunge the dirty tool in the bucket a few times; the sand scours off the dirt and the oil helps prevent rust.

I’m gonna try and use the fuck out of that thing and compare it to the Knipex.

I never realized there was a Kobalt version too. A 2-pack with an 8” and 10” is only $20. They don’t have straight jaws like the Irwin and Kinpex versions though, which could be good in some situations but bad in others. I really wanted a pair smaller than the 10” Knipex after putting together a bunch of air lines and fittings with all different sizes and the Kobalt teeth would have raped that brass.

Almost got the Kobalts to try them out but they have this goofy switch mechanism on the back, plus more stamped sheet metal bullshit in between the handles and that looked like the spot where they would fail.

Rainwater is causing a lot of holes to show up in the dirt near my driveway. Would dirt mixed with gravel fair any better, or would it just erode too?

>>1636720
The tip of the bolt will have the lead sink. The line will be threaded through the tail end of the bolt. When i reel in the line it will bring the bolt back.

>>1636839
Install a French drain. More work than just filling the holes in but anything else will just continue to erode, so it's actually less work in the long run.

does anyone know anything about diy tin canning? Want to can some stuff up for camping and for obvious reasons dont want to use glass jars.

For keeping out a variety of bugs does store-bought pesticide spray perform significantly worse than the professional stuff the pest control guys use?

Also is there a sort of general "best practice" for treating mild chemical burns?

>>1637317
>For keeping out a variety of bugs does store-bought pesticide spray perform significantly worse than the professional stuff the pest control guys use?

No answer on that, but after trying many things over the years, this product actually works for me. It supposedly lasts up to 3 months, but I spray my underpinning once a month, and the huge fucking cockroaches or palmetto bugs or whatever they are just show up dead outside instead of running around inside. One pint was about 50 bucks, but you dilute it. I use 0.75 oz to about a gallon of water, so the pint lasts about 21 months.

Hello I am looking for an oscilloscope. Mostly for working with Arduino and monitoring EMI in wires. I found a Hitachi V-650F for 100$. Is that an OK deal or should I go look for something else.

>>1637791
>monitoring EMI in wires.

Please elaborate on this. You cannot post too much detail, so go for it.

>>1637799
For example a project I am working on atm. A 3phase motor frequency drive controlled by Arduino through modbus. I was getting false readings on the arduino IO pins when the motor was starting or switching speeds. I replaced the signalling wires with shielded wires and it seems to be working OK now, but I want to see if I can reduce the interference further, so I decided that is about time to get an oscilloscope.
Maybe there is a decently priced Digital oscilloscope I can get, my budget is around 600$. Is it worth it, when compared to used analogues?

>>1637821
>when compared to used analogues?

If they are storage scopes and have equivalent bandwidth they are as good or better than digital. On the other hand, digital are inherently storage and tend to have lots of other neat features, so if the bandwidth is adequate I'd go with digital if I could afford it.

Is this a sensorless drive, where you monitor the EMF of an unpowered phase? I'm toying with the idea of trying that on some old motors I have lying around.

>>1637822
My guess is that >>1637791 is not a storage scope.

I am using Parker AC10 0.20kW 230VAC 10G-11-0015-BF. I am not sure about the EMF monitor on this one.

>>1637840

I read your post wrong anyway. 3-phase frequency drive is an AC motor, and I was thinking BDCM. Sorry about that.

How do I get this chemical smell out of my apartment? All rooms have this vile chemical smell, like a dentist office or a new car. There are no open containers like paint/solvents or anything that could be responsible for the smell. Even if I open all windows to vent for hours on end it still comes back the next day. I have tried an ozone generator, spraying the walls with febreeze until they're drenched but it never goes away.

>>1637920
I never know where to start. I get 80% of the shit together and then get distracted by life and pussy and don’t get it done. I still need to tune the carb on that chainsaw.

urgent question, friends. I have 3 shitty (broken) motors I have to get rid of quickly, would I fine dumping them in my apartment complex's dumpster? Think small honda-type motors, the exact one is pic related. Originally got them for free for a project but realized it would be cheaper to get a Predator 212 than to try and get them running again. I need the trunk space for tomorrow morning.

>>1637790
Don't use OSB, you'll have to redo a lot when you get a roof leak later. Plywood is okay, hardwood slat would be better but may be cost-prohibitive. If you're going with corrugated metal roof, you could just use lumber runners under your mount points (screws go in the peaks, not the valleys).
>>1637869
>DIY reading list
I don't know of one that's all nicely condensed and tidy and pretty to look at for whatever project you happen to have in mind, but if you look at the original post of the General threads there are occasionally reading lists. The threads that come to mind are Homegrowmen, Machinist, and i bet if you check the archives you can probably find a decent list from the old woodworking generals. Give me more detail and I'll give you a better answer.

Wash the chemical off as quickly as possible. Over the next few days, keep the burn dressed with neosporin or similar.

First of all, are you asking about just using logic gates in general, like how you put them together to make something useful, or something else?

Second, is your plan to use DNA for computation purposes, or are you designing organisms to respond to different environments in different, predictable, pre-"programed" ways?

hi /diy/
I did something without thinking it through too much. I have a 2x4 and I drilled a couple of 3/8" holes in it as shown in picrelated. The holes have a force of maybe 40lb applied to it. The force is applied with a threaded bolt that goes through the drilled holes.

Did I fuck up in terms of structural integrity of the wood? Should it be able to do 40lb in that region at (force vector might be pointed slightly downward)

>>1638713
>The holes have a force of maybe 40lb applied to it
From the image, it looks like the force is being applied to the wood adjacent to the holes.

>The force is applied with a threaded bolt that goes through the drilled holes.
A U-bolt? Is it held in place with nuts on both sides? How is the bolt supporting the load?

>Should it be able to do 40lb in that region
A 2x4 can support thousands of pounds depending on how it's loaded and supported. 40 pounds is so negligible compared to the strength and size of the material that you're unlikely to have something so poorly designed that 40 pounds will overload it. That said, it's possible, and your omission of important information suggests that you aren't used to thinking about structural loads. So:

You drew the 2x4 as floating in space. With a 40-pound load applied, it would zoom off to the left. With an out-of-center load, it would also start spinning. I'm guessing that the real board won't do that. How does it interact with the environment around it? Is there anything holding it in place, to which it will transfer the force of the load? Where and how does the board connect to that? How long is the board, and how far off-center is the load? If the force vector is pointed slightly down, how "slightly" down is it?. Is it a chain or something that runs through the U-bolt that can dull from various directions, or is there a rigid connection that can impart ending moments too?

>>1638726
>Is it a chain or something that runs through the U-bolt that can pull from various directions, or is there a rigid connection that can impart bending moments too?

>>1638726
It's part of a frame I made shown here:
>>1634582

>There is a spanning horizontal 2x4 connected to two vertical 2x4s. One of the vertical ones is shown in the picture.
>A ~50-60lb AC leans back on the horizontal 2x4 to prevent it from falling out the window
>40lb is just an estimate with some FoS (like 2x), since the A/C also sits on the bottom part of the frame and some of the weight will be distributed there

I didn't like the idea of only using woodscrews to connect the load bearing 2x4 since the force direction was 'pulling the screws out' so I drilled holes through and used theaded rods plus nuts.

But looking back I took out a lot of material drilling those holes in a tight space which is my concern.

>>1638726
>>1638734
Also to clarify re: the environment, the frame is situated on a window sill and surrounded by a half inch inset ledge to keep it in place on one vertical side and the bottom.

I've wanted to get in to woodworking for a long time and I basically have all the tools I need, but my problem is that I don't have an adequate space for it.

I don't have a garage and I have a shed that doesn't have electricity. My house has 1 outdoor outlet, and I have an extension cord with 3 outlets on it, so basically I can have up to 4 tools plugged in at any time, but I don't have a workbench that's easily moveable. This means that I have to haul whatever I need from the shed to my deck and constantly move things around and swap them out to try and build a piece, plus room to do it. It's really draining on motivation.

That being said, is there anything I can do to improve my space? Would it be worth it to shell out money for someone to build a garage for me and get electricity run to it? Should I just wait until I move (within the next 2 years)? I thought about solar panels on the shed, but between all of my tools and other outdoor shit PLUS my wood stock there's not much room to make it worth it anyway

tl;dr Not a lot of space for woodworking, how do?

>>1638805
>but I don't have a workbench that's easily moveable

You're an idiot.

I have a small, 2 bed apartment. The heater works fine and will do 65-70F even if it's -5F outside. The A/C however refuses to work properly past like 80F. If it's below 80F outside it'll be okay and can keep it 70-72F. If it's anything above 80F it will not drop the inside temp below 78F period whether that's a delta T of 2F or 20F. Can someone tell me what the fuck is wrong with this? My understanding is that a residential unit should be able to do at least a 10F Dt and should be able to handle 20F Dt. We don't have anything that puts out crazy amounts of heat and last summer was the same shit and we had $200+ power bills for fucking nothing. We're the only ones that have this problem.

That's what I was thinking too, the unit is probably pretty old. I don't have personal access to it, it's central A/C and it's on the roof which is locked. (It's a small, 2 story/4 unit building)

I just want to play around with compressor and shit, to get an idea how refrigeration works.
Getting fridge from recycler is not an option. Same goes for window AC.
>>1639172
I'm not an expert, but I think you will have problems with oil becoming sludge, since R134a requires synthetic stuff.
But I think there are blends that replace R22, which contain R134a.

>>1639189
Just read the label and this is R410 or some shit.

I’m not sure what it is. I turned it on and the fan runs, but no compressor and the fan that blows hot air out the back was off. Then 5min in the compressor turns on and I get cold air from the front and hot air blowing out the exhaust like it should for 2min. Then the compressor turns off, getting room temp air from the main fan, the exhaust fan is still blowing out but not hot anymore because no compressor.

Before people said low refrigerant but I don’t see anywhere to possibly refill the thing. Looks like maybe they filled it at the factory and then clamped the little copper pipe. It got nice and cold for the minute or two the compressor was on so I don’t know.

>>1633609
Sounds like a grounding issue. Either something is coming loose or there is just a bad ground. Usually a worn solder point along the signal chain inside of some hardware if it isn't just a speaker wire.

Is it all speakers? Subwoofer? More deets plz

>>1633674
2 stroke or what? On a 2 stroke it usually is running lean meaning carb issue or vacuum leak at idle. Also a lose timing arm could raise and lower rpms enough to be audible.

>>1639194

It might be a bad start-up capacitor.
Check it for leaks.

>>1639223
Hmm. I haven’t touched it in months and months because I thought it was leaking. I just started messing with it now and that minute or two I got cold air from it seemed as good as new. So would I get really cold air for 90 seconds and then room temp for an hour if it were low refrigerant?

>>1639227
That is mobile AC right?
If thing is critically low on refrigerant, you would have ice building up (at least that is what HVAC niggers told me). And that is factory brazed unit without flares or valves that might leak. But I would still check, if some pipes are rubbing on each other.
So, I suspect electronic PCB or/and start-up capacitor. Find it and check its capacitance.
Replacing capacitor is easy, usually it has terminals (don't know how they are called, but you can remove them easily). Replacing electronics is tricky, and I would replace it with simple thermal relay.

>>1639229
I believe I found the issue

>>1639230
So what am I looking at here?

>>1639230
Kek. How did it even start?
You may try solder this, but I recommend crimping new thing, since this is vibrating stuff.

>>1639231
That burnt wire probably got loose, and started arcing.
Inverter or normal unit? I will google for schematics

>>1639232
Idk, it ran for like 90 seconds.

So you think that relay and everything is still good? I can order a new one for $10 assuming the new one doesn’t burn up like the old one. I had been running the thing pretty hard in my garage when it stopped working like a year back

>>1639234
That’s what I was hoping. I’ll put some fresh wire and/or terminals on there.

>>1639234
>>1639236
Whatchu think the best route would be to clean up this connection to make sure there’s no more resistance and burning? I guess I start with wire brush.

>>1639240
Went at it with the wire brush, them a dremel. I think I’m going to solder the new connection. Other ones seem tight. It sucks though because it’s one of the regular terminals where it burnt up, but that wire is soldered or something to the overload relay on the other end. I would like to replace the whole wire but I don’t think I will be able to get nearly as good of a connection on the other side.

>>1639247
Just bypass protection for now I guess. Test if shit works, and than I'd probably solder something directly to that pad and cut that crusty wire off.

>>1639248
Meh I connected it all up and smothered the new one with some liquid electrical tape. Waiting for that to dry and then I’ll get it back together enough to fire it up.

Annoying thing was the original terminals was some 90deg one so the wire runs perpendicular to the plug. Only ones I had were the typical straight ones. Plus I took a dremel to the burnt up connection to get it to bare metal. We’ll see if that makes enough contact with all of the solder in there.

>>1639263
You can test it white tape is wet I guess.

>>1639273
Seems to work. Pic related, ambient is 83F. I guess I can keep an eye on that connection to see if there’s a glownut before I put it back together.

>>1639276
Does it have a drain pan for condensate?

>>1639287
Yeah. When you hook it up there’s a duct coming out the back for the hot air off the condenser and then a little hose for the water off the evaporator.

This thing doesn’t do much in an uninsulated 2-car garage during the day, but when I’m out here on muggy nights it will eventually drop the temp 3F-5F but best part is that it dries out the air. When it’s real humid, it will fill up a 5gal bucket in a couple of hours.

Last time I used it inside the house during a power outage, I had the duct running out a sliding glass door (comes with adjustable plastic dividers to close off the gap in whatever window or door) and I was able to run the condensation hose right out the bottom of the door.

>>1639247

when centrifugal switches or magnetic relays fuck up i just rip em out and put in a toggle switch for the start winding.

flip both toggle switches to start motor, flip off start winding switch when motors up to speed. wont work with anything that starts automatically though unfortunately

is it just me or are captchas getting stupid hard

I think that connection may have rattled loose and started to arc and overheat so that probably wouldn’t be the answer. Sounds like a pain in the ass on this thing anyway with the thermostat and multiple modes.

Also stoplights and crosswalks are cancer. I use the pass most of the time because it’s annoying. Also once a year they lay down all these mobile IP bans and I’m pretty sure it’s a Mook moneygrab since he took over because every 11-12 months you can’t post without wifi or a pass and they always pop up when the old pass is about to expire and disappear a month later.

I was once really into motorized bicycles and I wanted to make custom exhausts and sell the bikes. I found a vid. on Colin Furze You tube channel where he makes a pulse jet engine. The dude cut out two identical shapes of sheet metal, welded them together around the edges, welded a fitting where he attached a shitty pressure washer pump. That shit puffed up like a balloon and had cones and bends and different diameter sections of tube.https://youtu.be/bCsg5pQimWI

You attach what is called a saddle valve, It pierces a small hole in the copper tube allowing charging then you close the valve when done.

I need an x/y Vise for a drill press so I can pretend it is a milling machine for an 80% AR-15 lower. I don't want to break the bank with it because it will only be used 3-5 times ever. What can you recommend that isn't useless trash?

>>1639223
It sounds like you are telling to check capacitor for leaks, I'm sure that is not what you meant.

>>1639294
Thats a lotta coke diabeto.

>>1639428
Those cheap x/y vices are shit, you wont mill anything with it. If you are good with layout work you can get some pretty good results with a dremel but it takes patience and skill bot it WILL be better than trying to use one of those vices. What are you trying to do, a pocket, a slot, square hole?

>>1639434
Square hole, it's for polymer 80% lower. How much do I need to spend for a decent xy vise?

/diy/ I want some plywood or something similar that will stand up to rain (to cover an open window), about 20" by 15". What's the cheapest thing I can get for this purpose from like home depot? I don't want it to rot/disintegrate when it gets wet.

>>1639435
I've never seen a decent xy vice. They may exist but whatever you are going to mount it to will not be rigid. Since it's polymer it may work.

How do I measure consumption of an on-off air conditioner?
I just want to know, if higher heating temperature actually increases consumption.

Probably vinyl film, though it comes in rolls larger than that. There should also be small sheets of plastic that might be cheaper than a small piece of exterior plywood.

How can I learn about car wiring? Where can I start?

>>1639662
Something like a kill-o-watt (or a multimeter) and time it. Find out how many minutes of every hour it is on vs off and then math it out.

>>1639662
>>1639682
Is there a Kill-O-Watt that records? They must have a data logging one. You could do a clamp meter and a line splitter too but you’re going to have to time it and do math.

>>1639681
Look at wiring diagrams? Look at the car itself? What are you trying to do? Do you have a current problem that needs to be diagnosed?

Power Probes are GOAT for diagnosing wiring issues and any respectable mechanic will own one. But poking around with a multimeter and logic-safe circuit tester will tell you a lot as well and keep you from frying shit with the Power Probe if you’re a complete retard like myself. Power Probe will give you voltage readings on all sorts of stuff though and you can send battery power or grown to individual parts and wires to help you figure out which wire goes where and which part of the circuit is fucked.

>>1639662
>>1639682
>>1639683
Nevermind, the Kill A Watt does measure consumption. Set a timer and measure the usage over however many hours with the settings you want to know and compare the two. At $20-$25, that’s way better than using the line splitter and fucking up all the math.

>>1639682
>>1639686
>>1639683
>multimeter
There is a problem. AC is an inductive load with bad power factor. (220V 5A for supposedly 800W)
My multimeter is not even true RMS.
And I can't use 800W figure, since compressor consumes different amount of power over time.

I guess I will have to steal an electric counter somewhere, or buy kill-a-watt thingy.

>>1639681
Shit pic didn’t even have the Power Probe in it.

If you’re a shadetree mechanic by any stretch, it might be worth grabbing one since the basic model is only $60 and it’s so much faster to check connections and wiring than other methods. Works great for testing fuses too and should be logic safe unlike cheap test lights (basically those cheap test lights pull power through whatever circuit you test, so if you’re testing power on sensitive low current stuff, you can pull too much power through it and fry the thing you’re testing).

You gotta understand DC electricity and relays and fuses a little bit for cars. Understand that cars are negative ground, which means the frame is all grounded meaning basically any bare metal on the frame and body is connected to the black (-) post on the battery. So if you want to power something, you run the red (+) wire through a switch (and often a relay) + fuse, into the + of whatever device, and then the - wire of the device will be grounded to the frame. So when playing with electricity in cars, if you have a red wire with 12V + running through it, don’t just let the thing hang around touching bare metal or you will get a short circuit and some sparks-heat and maybe fire.

Read up on relays, you don’t want to run lots of power through switches for lots of reasons so the switch to turn something on/off actually sends power to a relay, just enough to activate the little magnet in a relay (as opposed to the power needed for bright headlight bulbs which is much more) and the relay acts like a switch for the higher current going to a power hungry device like headlights or horns or starter. Having lower power running through the switch means you don’t have to run thick ass wire from the battery all the way to the switch in the cabin and back down to the device in the engine bay.

>>1639694
I was suggesting a clamp meter and line splitter. But at $25, the Kill-A-Watt will do everything for you so it’s not even worth the time staring at the currents and trying to time it and end up with shitty non-precise results anyway.

Are you in the US? I think Harbor Freight even sells the Kill-A-Watt

>>1639701
>I was suggesting a clamp meter and line splitter.
Hm... I guess I need to buy a clap meter (hall sensor one, so I can measure DC too).
It is a shame that electronics engineer student doesn't have any fucking equipment.
>Are you in the US? I think Harbor Freight even sells the Kill-A-Watt
Unfortunately no.
Also, I can't find kill-a-watt with Italian plug, so I guess I will have to hack it together...
Maybe I should get a multimeter, which can measure power (and power factor) as well?

>>1639707
Don't forget to make your own DVA adaptor as well to get your peak readings.

>>1639707
AC power is voodoo to me. But yeah clamp meters are good to have. If you get a DC clamp meter, read the reviews though because they’re not always very good at getting steady readings on lower current DC. Electronics people seem to love that small Uni-T clamp meter. It’s one of the most affordable DC clamp meters, probably the most affordable from a brand you can somewhat trust ($50 in Burgerland). It doesn’t read very high currents, but you won’t be messing with 600A wires when you’re playing with Arduino projects.

Oh and the line splitter, they must make them for Yuro outlets and plugs. I’m sure you can find one online.

>>1639707
>kill-a-watt
Try looking for a "power monitor meter" on your search engine of choice, you may get better location-specific results.

>>1639683

power probes are a meme and not necessary if you have a decent meter. there is rarely and i mean very rarely a time when its more worth it trying to pinpoint the exact location of a fault (eg broken wire, rubbed through etc) rather than just to rewire it.

a good mechanic will study and fully understand the circuit and how it works, and then remove, re-pin, and rewire.

little point in spending hours tracking down a broken wire and fixing it, just to have another one break somewhere else in a week. rewire it and be done with it.

>>1639749
Of course they aren’t necessary. Lots of tools aren’t necessary but they make jobs a lot easier.

>>1639736
I have tried, and I can't find with type Italian plug, only schuko. Not big deal, but kinda not ideal.
>>1639718
I wanted exactly that small UNI-T thingy.
>>1639712
Hm. I always used similar setup.

>>1639751

sorry i was trying to be polite when i said not necessary. theyre totally useless is what i was getting at

ive seen people use them on 3 separate occasions and all 3 times they did more harm than good

a good mechanic goes out of his way to avoid poking holes in wiring. if i had a nickle for the amount of times ive had to fix something because somebody was in there poking holes. if i need to power a component ill unplug it and use its connector. sure you can do this with a power probe too but since you have the connector unplugged you have to make a jumper for the ground anyways. that or leave it plugged in and just poke into the power wire.

and as far as continuity testing how is hooking each end of a power probe to a wire any easier than a multimeter?

rather than looking for a light or listening for a beep, learn to read resistance. that alone will set a mechanic way ahead of the game and be far more useful than a power probe ever will

>>1639815
The thing basically is a multimeter. The 3 is a voltmeter and continuity tester, the 4 is a multimeter. Easy replacement for a test light without dealing with two leads like a regular multimeter. You don’t need to pierce the wire in any spots you wouldn’t pierce the wire with a regular meter, I’m not sure what kind of moron you had in your shop stripping insulation off wires to check voltage and continuity.

Most of the mechanics I have seen come through our fleet department pull out PowerProbes way before regular multimeters because they’re faster and more ergonomic when dealing with automotive DC. And forget the test light because you already have the Power Probe sitting on top of your cart and it will tell you more info while being just as simple to use.

>>1639815
>>1639855
And the other thing, the main one that makes the Power Probe different than an ergonomic and simple automotive DMM- the fact that you can send power and ground to stuff with the click of a button. Want to know where exactly the fault lies and why this fan or horn won’t work? Start sending power at different parts of the circuit and see if you have a wiring issue of the component itself is bad. I know a lot of the reviews were dudes who wire up trailers and lights and it is the most efficient tool for jobs like that. Of course you could nigger rig something up if you don’t value your time, but dudes working on book hours aren’t trying to do that.

>>1639855

you missed the entire point of my post. piercing wires in any way shape or form is for the mentally challenged. i have no use for a test light either. as my multimeter does the same thing. what makes you think theres a difference between piercing wires and stripping insulation off? have you ever seen the mess poking holes in wiring that has constant draw can create? just because its a tiny hole doesnt mean its harmless. ill say it again, if i need to power a component ill unplug its connector and use that, or ill cut the wires and properly re-splice. poking holes is shadetree retardation, and all the braindead truck mechanics that use power probes do it because they dont give a shit, and nobody will attribute them to the reason their trucks wiring is falling apart because of all the holes poked in it a year ago.

probably half the electrical i fix is because some ape that didnt know what he was doing poked the shit out of the wiring and now its all falling apart

and who needs a power probe to wire lights? or to know if a fan works? unplug check resistance between power and ground. open loop or anything stupid high means its fucked, a low resistance means its shorted, etc

>value my time

yes my time is very valuable, so i take the necessary steps to avoid having to waste time rewiring things because they were poked relentlessly.

damn wish i had a power probe so i could spend 5 minutes tracking down exactly where the break in a wire is while absolutely fucking the wire full of holes in the process and end up needing to rewire it in 5 months anyways because its completely green inside

>>1639877
I wasn’t recommending piercing the wires in the first place. Most people don’t

>>1639881
And you could use the Power Probe 4 for the exact same thing and any other electrical issues and only need to use one hand.

Have you ever owned or used one? I think you saw some idiot use one once and he was piercing a wire every 10” so he could replace one small section. That’s not exactly the main use for the tool.

>>1639881

>I wasn’t recommending piercing the wires in the first place. Most people don’t

so to send power to a component you unplug it and use the connector? so you must also make a jumper for the ground pin because sending only power into an unplugged connector wont work as theres no ground path. so how is this any easier than just using a multimeter?

>I wasn’t recommending piercing the wires in the first place. Most people don’t

>You don’t need to pierce the wire in any spots you wouldn’t pierce the wire with a regular meter

????????

and as for your one hand argument, i have a clamp with a long lead on it for my negative and i just hook it straight to the battery negative and it works in most
situations. so most of the time im only dealing with one lead anyways

Yes that is one of the things. I read a comment with about +1 cm only for width but im not sure if this.
Also i have some weeks left....

>>1640015
just built a bed over christmas, building another now. looked up the size online, cut the bottom to be exactly that size. mattress as arrived was a little bigger than advertised (ikea). works fine not a problem. if you build it from toilet paper it might not hold up but wood should be able to overcome a mattress springiness.

>>1640538
I was just trying to think about my wood frame bed. I broke the original thing and have rebuilt it better and stronger so I can make her feel like she’s in freefall without the mattress actually crashing to the floor.

Depends on the design and materials too I guess. +1cm per side is different than 101cm for a 100cm wide mattress. You don’t want the thing to slide around when you jump in, but 5mm doesn’t leave a whole lot of room for you to fish out the Skittles that fell down the side of the bed last night. Also are you using a box spring? Box spring could probably take the tighter tolerances whereas mattress will be pushing against the sides with only 5mm.

I have a brand new house. It has four bedrooms on the second floor. One of them is always significantly hotter than the rest. Each room has its own thermostat and the hot room is usually 3-4 Celsius higher than the others. How do I go about fixing this? The hot room and another room both have a single window, and both those windows face the same direction so it can't be that the hot room is getting more sunlight than the others. All the rooms have radiant heating, but its summer now so the heat is off. Is it just poor insulation for that room or what?

i just moved into a new place and i suspect none of the sockets i have are properly grounded.

the old sockets are only 2 prongs w/ no ground however there are newer outlets wired in that have a ground hole as well.

i can just check this with a test light, right?
if it doesn't light when i stick it in + or - and use the ground hole as out, does that mean the ground prong isn't wired?

>>1640835

What's under that room?
Are trees shading the other rooms?

It's not a big thing. Don't worry about it.

>>1640889

Then you need to pull all the wiring out of the walls and replace it with wire that has a ground wire included.
You can then replace the two prong sockets with standard grounded duplex sockets.

>>1640912
ok, so i can check that with my light? if the ground isn't connected it won't light right?

>>1640873

>the garage
Is the garage heated and cooled?
Any heat in the garage will rise to heat the room above.
There probably isn't any insulation in the garage ceiling.
If the areas under the other rooms are cooled by the ac, there is no added heat to rise into them.

Is it worth buying an angle grinder/ bench grinder, or should I just stick it out with a file?

So I need to replace the roof on my 4.7x9m house extension but the angle is 8 degrees and the new roof material needs minimum 10 degrees.

>>1641272
The thermostats only control the heating and its already off because summer. AC is handled by a split-system central air conditioner, its either on or off, its not divided into separate zones.

>>1641077
The garage does not have any heating or cooling systems as far as I know. I guess the only way to check the garage insulation is to remove a section of the ceiling there right?

>>1641293
But then you wouldn’t be able to see the discount codes!

>>1641314
>I guess the only way to check the garage insulation is to remove a section of the ceiling there right?
Garages are seldom insulated in the ceiling.
The walls will probably be insulated like the rest of the house.
You may be able to check for insulation by taking down a light fixture and examining closely around the box.

wait until it snows, see how long it takes to melt on the roof of the house vs garage

Does anyone know where I might find a small neat enclosure for a rocker switch like in this pic, but less chinky? I need it to be durable and reliable.

I've had an extra microwave stored out in my shed for a few years, decided I want to use it but I'm wondering what I need to do prior to bringing it indoors. I took it out of the shed and put it in carport (thinking the jostling might scare any critters out). I might take the air hose to it as much as I can. I don't think there'd be anything in it short of dirt daubers, ants, wasps, maybe. The shed was not impermeable though so there's always the chance for rodents, snakes, spiders, beetles to get in this thing. Any advice?

my gf has been needing a new retainer for awhile now but the prices are outrageous. I had a wad of aluminum foil in my hand moments ago, and when I bit down on it it left a nice mold of my teeth. So, I think you know what I'm thinking.

Can I pour a plaster cast into this, then somehow form a retainer over the new cast of the teeth? I will probably scrunch up a wad of tin foild that roughly follows the contour of my gfs jawline, have her bite down firmly, pour plaster into the new mold, then I'm not sure how to make the plastic retainer, but is this feasible? What materials should I use for the retainer?

I am looking for a power supply that will power half a dozen stepper motors and their drivers, and possibly some LEDs also. I'm just looking for a general purpose power supply for electronics and robotics hobby stuff. I'm in the UK, any suggestions of the sort of thing I should be looking for, I really have no clue where to start.

I need to supply power to 6 stepper motors, hobbyist tier robotics stuff, and would also like it to power LEDs, servos, just whatever the fuck I hook up to it, but I want my own self-contained PSU.

My 3D printer has something VERY similar to what I would like, kinda, it powers fans, a screen, a bunch of motors and heating elements/sensors, that's basically what I want, but where do I go for that kind of thing!

For this project, six fairly beefy steppers and a bunch of LEDs are the bare minimum though
