What should i draw up in fusion and print today? Im bored of html\css courses and want to spend a few hours creating something.

If you don't want your questions answered post in this retarded thread.

I'm printing my own keychains, but the metal ring is rubbing through the holes after a while. I thought about inserting a metal tube as seen in the picture into the hole, but I don't know what that kind of thing is called.
Any idea?

It's you again. Why do you hat QTDDTOT so much? I get that the board is almost dead and individual questions may help but some questions really are worthless, so why not try and get a answer here?

is alibaba legit? has anyone ever purchased through it before? good experiences? horror stories?

Because no one will answer it.
Though these people are also so retarded they post in this pointless thread when they should know already they won't get an answer.
I guess they don't deserve an answer when they post here.

My radiator is set to 0 on the thermostatic valve but it's still belting out heat. I'm in halls of residence and the uni won't turn off the heating and they can't isolate my room. I see there's a little white cap with a screw in the top on the other side of the radiator, if I turn that will I turn the radiator off completely or will I make a geyser?

I go to a dealer for repairs because I'm an apartmentfag, and they just do a better job than the mechanics in the area, and one of the mechanics told me that to defog my headlights, I should just use bug spray with DEET in it, because the DEET will get rid of the yellow shit.

How legitimate is this?

How I should patch a big hole in drywall?

1. Make hole square
2. Cut a piece of drywall, that would fit in the hole
3. Screw support wood to drywall.
4. Screw a patch
5. Apply mesh-tape around patch
6. Apply filler or joint paste? so it is sort of flat with wall
7. Sand it
8. Paint.

Am I right? Hole is from my head...
Never dealt with drywalls, only with wood, brick or concrete walls, it is kinda new material to me...

>>1307817
your phone's a computer, it does whatever the fuck you want
problem is that no one does what you want
/diy/ and phones are NOT compatible, unless /diy/ means /buyshit/

>>1307820

1. Make hole square
Cut piece of cardboard that is slightly bigger than hole and
Put string through cardboard, knot at end and pull tight.
Put glue around perimeter of card.
Put card in hole, glue side out, pull string so it seals hole.
Use cardboard a base for plastering.

Who the fuck thought these were a good idea?

Why wouldn't you just buy a cheapo standalone sensor? There's no way it would cost more, even including the batteries you'll periodically need.

TL;DR: Is there an arduino-tier choice when it comes to FPGAs? What is generally reccomended?


I've been working on a project involving torque control of a 3-phase (PMSM/ basically a bldc) motor.
This involves measuring the current in each of the 3 phases going to the motor, keeping track of a 10 bit rotational encoder, doing a few calculations and finally producing PWM to control three bridges for power to the phases of the motor.
I made the prototype work using a teensy 3.6 (180 MHz and arduous compatible) as processor, but it seems to be barely cutting it.
I'm going to take the project next level by adding a second motor with torque control as well, and then I doubt it'll be enough with the teensy.
The trouble is also that the currents should (ideally) be measured simultaneously and at just the right moment, relative to the PWM signals.
I know I can save a lot of time by adjusting the adc as well, but I'm curious about trying an FPGA anyway, not to mention the advantages of synchronous processing.

So... any recommendations on a "beginner-friendly" FPGA that can handle 6 analog inputs, 2 interrupts and a few digital general I/Os?

>>1307512
I need to remove the knobs of various potentiometers and slide switches to be able to remove the pcb from a 80s alarm clock radio, I have not figured out how to take those off without breaking them.
Could some /ohm/ guy or anyone really assist me with this?

Picture for attention.

>>1308230
Have you checked if they're held in place with grub screws?

Most potentiometers are hold in place with either that, or just friction.
Same for slide potentiometers as far as I know.

If they're glued I have no clue how to get them off safely though.

>>1308232
>Most potentiometers are hold in place with either that, or just friction.

I saw no screws so I tried brute force, shit was tight but they came of intact. Thank you anon!

What can I personally do about a slightly bowed foundation? When I say slightly I mean that its less than 2 inches at the furthest. I already added gutters to the house and a gradient but the updated drainage had to wait until spring.

I want to get a big ass 00 cut bastard file for hardened steel. I've been looking for one for weeks now and didn't even got close. Can you point me into a direction? The bigger is the merrier.

depends on local building codes (if any) and if there is a frost line you need to get below; for a shed - probably not. ar ound my neck of the woods sheds are usually built with wood floors up on top of some concrete peers which may or may not sit on top of some other concrete blocks set into the ground. over freeze thaw cycles the shed might shift a bit but usually no big deal. if it really starts to lean too far in one direction then you just get a floor jack or bottle jack and jack it up and 'shim' the peers to level it out again.

>>1308099
even if it doesn't seal 100% it should do enough to divert water up to a shower head... the one I have leaks a bit but shower head still works fine. the old school ones were of course much much better built, better thicker metal and more accurately cast. I had to replace one that was decades old - hard to get it off but once I did you could feel the difference in weight and see the quality difference in the metal and casting. old school one had brass parts on the inside. new ones are cheap brittle plastic and cheap thin crap [pot] metal. we're in a race to the bottom for pretty much everything these days. its all about cheaper faster but definitely not better.

So I'm moving on Sunday and I have this front load washer that I bought from Lowe's a year ago. It takes 3-4 bolts to lock down the drum on the machine so it doesn't get damaged in transit. Apparently it is Lowe's SOP to trash the shipping bolts when they deliver the washer, and since I was at work when they delivered it I didn't find out about this until last weekend. I ordered new bolts but the winter storm delayed the shipping so they won't get here in time. How much damage could happen if I move this thing down two flights of stairs and 18 miles in a truck without the bolts? Also, fuck Lowe's. Even the user manual says to keep the bolts.

>>1309012
figure out the length size and thread, get similar bolts at store and rubber stoppers that fit inside the holes. drill though the stoppers and put the bolts through them and viola.

Can anyone give me a good guess of the type of wood here? Trying to sell this table.

Is wd-40 adequate to give this old belt sander some TLC? Gonna open and clean it, and my only options for lube are wd-40, motor oil, vegetable oil, linseed oil, or semen.

>>1309059
It looks varnished and possibly stained. Unless you can get a picture of it where it's untreated, we won't be able to tell you. But holding a ruler up to the grain and maybe calculating its density would definitely help.

>>1309062
Ah, I could've done that with the top if I hadn't spot touched the areas with a felt pen beforehand.

Does this picture of the underside make it any easier or would it be layered and different? Forgive me for my inexperience

What is this called. I can't find anything for this online. It's a lead acid battery pack for my electric bike. It's 6" by 14" by 4". It has a roughly 2.75" by 11.25" groove piece. I need to find a replacement case.

>>1309136

Who is the maker of the electric bike?
What is the voltage on the battery?
What is the cranking amps?

>>1309146
My bike says pegasus on it. Here's the logo...

>>1309153

Dug around for a little bit.

I don't know anything about the e-bike market, but I am guessing that pegasus sticker is a chinese knock off of the French quality bikes. Mostly irrelevant information.

I was only able to find lithium batteries and not a direct form factor replacement unfortunately. Is the bike older?

>>1309166
I have a feeling it is since it came with lead acid batteries. The number on the bike reads PLO6B078.

I have a side by side charcoal propane grill. Not gonna lie it's some Wallyworld tier POS. I put it together about 4 years ago. The regulator went bad. I cannot for the life of me detach the old one from the propane line. WD-40d the hell out of it and nothing. Any clever ideas to loosen it up? If I snap the line I am going to buy some tubing and convert that side to a smoker. But its the bigger half of the grill so id like to save it if possible. Yes I'm asking for help loosening a nut. If you're going to sperg out on me don't bother.

Any idea what I could use instead of a CD case that would be bigger for a hologram projector? Or just some way to get a bigger hologram without spending >$20USD

>>1309234
Also a bonus weird question to this, does anyone know how I could make the holo bigger without using a bigger screen? I'm ineterested in making a bigger holo but everyone on YT seems to end up using bigger LCD's with trapezoid projectors on the screens, this kinda seems to defeat the purpose if you ask me why not just watch the screen?. I did see some guy manage to project a full size miku hatsune onto a wall (160cm) but he didn't explain it (and I can't find it anymore).

how do I make a desk that won't cause my monitors to fucking wobble everywhere when I type without making it insanely heavy?

Adding to this, how the fuck do you actually buy from Alibaba? Don't you have to havea registered business to order from there? How do people get around it?

Couldn't get ahold of a plumber due to the weather this time of year, so I'm doin' it live tomorrow!

Sewer/sink vent rotted out. Home Depot Masta Plumba said PVC was kosher.

Would y'all stop at the brass 4-way, or continue and do it all PVC? Underneath is unfinished basement. I'm in the US.

>>1309451
The good (sink drain as well as another on the other side. No issues as of yet.

>>1309453
The bad.

Apparently it's very common. It's where the vented moisture pulls and rots out.

Also, anyone see these green encrustations on the outside before?

>>1309451

i'v never seen copper use for vent or a drain its basically a waste of money unless they had some unused scraps laying around

Ahh - thanks for the insight. The last owners were dumbasses, so I wouldn't put it past them.

The house was built around 1963, so it may not be out of line with the era - finally decided to remodel our only full bath.

>Since the late 1950s, plumbers have been introduced to a wide variety of plastic pipe and fittings to be used in drainage, waste and vents systems ...

I just replaced the other waste arm with a metal one. Figures lol. Guess those aren't compatible.

If I want to make a fence for my router table or table saw, what should I use that will stay flat and true? I've heard that plywood resists warp when it is firmly secured, so maybe a piece of plywood for the fence with strips of plywood with the ply horizontal as supports? Would MDF be better? What about HDF? similarly, would I need to brace those? Just planning to buy the materials at the hardware store. Will the hardware store square this stuff up for me, or are they unlikely to have stuff like a joiner?

copper and cast iron break down over time. if you have the walls open and access to them, remvoe and replace with pvc

>>1309504
The plan is to replace the copper vent and drain with PVC. The iron is in good condition and also tied into the incoming sewer and 2 toilets. Totally above my pay grade - we're going to be here another 5 years max.

Thank you - kinda cements the idea of replacing the 4 way brass (drain - vent - sink -
sink) with PVC.

I have one of these in my garage. It is a steel power rack with a black powder coat finish. If I wanted to write numbers next to the holes, which method would last the longest? white sharpie, stencil and spray paint, paint marker etc?

>>1308224
>>1309125
following up: the zynq has just two ADCs.
same as the kinetis processor on the teensy3.6... it might have many multiplexable analog input pins, but the data sheet says 2 ADCs.
so if you need *simultaneous* measurements for 6 analog then you'll have to roll your own with multiple external adcs.

>>1309911
Durable clear coat over your method of choice. Stencil and paint if you want it to look neat. If you really want it to last, punch/engrave the numbers into the metal, then fill them with white paint. Sand/scrape down the overpaint to reveal crisp letters. Cover them with durable clear coat.

I have about 7 of these scattered in my attic, what do I need to do to them before adding blow-in insulation? Can I just screw a piece of aluminum or something to keep the insulation out of them and then blow?

Jesus fuck. This is why you don't mix metals in plumbing. Over time galvanic corrosion does stuff like this.

I had to rip out all the supply lines in one of my rentals because the previous owner used a playful mixture of iron and copper. Every few months I was in there replacing faucet cartridges because they were full of pipe chunks.

>>1309012
>How much damage could happen if I move this thing down two flights of stairs and 18 miles in a truck without the bolts?

None.

>>1310740

Does it reciprocate? uh..
Does the glass have to move back and forth or just in one direction?

>>1310739

I've been working on this same problem for a musical robot. Linear actuators of every kind are available, so you've got some choice.

The other thing you didn't mention but is important is repeatability. That is to say, how well to you need it to return to the exact same spot? 10mm? 1mm? 0.1mm?

If repeatability is not important, the cheapest and easiest thing to do is going to be a friction drive (as in, literally just a rubber wheel pressing against the rail) and a stepper. You'd need a homing switch somewhere and you'd need to return to it periodically, but it's a fast, simple, and reasonably precise system.

If you need it to be more accurate and repeatable, you're probably looking at a toothed belt and pulley system. Doesn't really matter if it's driven by servo or stepper. Not TOO much more difficult than the friction drive, but still definitely more involved.

If, for some strange reason, you need this thing to be very accurate and repeatable, you're looking at leadscrews/ballscrews. Significantly more expensive than the other options. Slower, too, but high-lead ballscrews can still be quite fast.

My gf was cleaning her nails and left a little cap with acetone on my nightstand, the acetone dissolved the coating and left this mark.

How do I fix? It's an old nightstand so I don't know what varnish was used.

The sink and counter in my apartment is not level and so water from splashes makes it way to the right part of my kitchen. What do I need to put near the sink to act as a levee and divert water back to the sink.
t.absolute fucking retard

Is is possible to build your own crawlspace dehumidifier?

>>1310875
Scrape it all off and varnish again. Though if you apply more acetone and spread it around before it evaporates again you might be able to get the existing varnish to dissolve and precipitate back into the gaps. I wouldn't bet on it though.

>>1310906
Peltier devices or a compressor can be bought, and from then it's just a matter of powering them along with a fan, heat-sinks, and a water collector. A thermometer might also help to avoid icing up.

So, the screw that holds the rotating brush cylinder on my vacuum keeps shaking loose.

It is a metal screw that screws into a plastic recess. What is the best glue to tighten it? I cannot just upsize the screw, because it'll weaken the whole shebang. Crazy glue already failed and Loctite is only for metal on metal.

So I fucked up and drilled too large of a hole for a switch panel cut out. Any suggestions how to fit a 12mm diameter switch on a 16mm hole?

so, this is my boiler. it's from my grandpa's house, he passed away recently
for who knows which reasons he blocked it so that no warm water flows. i need to get it back to work. it was set on summer mode, switched it back to winter mode, no effects.

Exactly none. One would imagine that the quashing machines suffer more during transit from the factory as they are shipped using containers and forklifts and idiots. Just check out how containers are handled in large harbours. A hit here , dent there. You won't punish it hopefully as hard as so called professionals.

So there's a pole barn and frequent flooding has rotted out the base of the poles. it's still standing for now but I want to make it structurally stable again. Which of these two methods ensures better resistance against strong current from flood waters?

Method 1: cut out the rotted part and replace with a new post, connecting them at a jigsaw joint. then screw a thick ass bolt in there and use metal braces to better hold it together.
>this method would be a pain in the ass to do as I have to dig down 8 feet and i feel like it would be less strong than the concrete but i'm uneducated

Method 2: dig down as far as i can around the post before water seeps in too much and then pour in a dozen bags of concrete. ez pz

What do I have to look up to find out how to calculate voltage drop and current draw for something like this. (Please excuse the probably poor labeling.)
I want to be able to power multiple RGB LEDs from a single arduino uno r3, but I'm not sure how to do my calculations. There are three (pwm) sources, but only one ground?
Even if you guys could just point me in the right direction I'd appreciate it.

>>1311168
Glue a washer to the inside of the plate and drill the washer to fit the switch....

>>1311492
Not an expert, but i don’t think blobbing the rotten post in concrete will stop it from rotting further....

>>1311494
You can calculate them all separately, since all that matters is the total voltage across all 3 (doesn't change) and the current through each LED (is independent of neighbours).

The equation for the necessary resistor for an LED is:
>R = (Vcc - Vf)/If
Where "If" is forward current, "Vf" is (approximate) forward voltage, "Vcc" is source voltage (5V in this case) and "R" is the resistance. Rearrange this and we get:
>Vf = Vcc - R*If
"If" is frequently 20mA for low-power LEDs, and chances are "Vf" is about 3V. Assuming 20mA, Vf = 0.6V. The current is therefore much more likely to be around 10mA, which would give a forward voltage of around 2.8V.

>>1311494
First find the resistor Voltage:
Lookup the forward voltage drop for the LED
Subtract it from the supplied (total) voltage to get resistor voltage (drop)
Vr = Vt - Vled

Then Calculate resistor current with ohms law:
I = V/R

Example:
If the LED voltage were 2V...
Vr = Vt - Vled = 5-2 = 3V
I = Vr/R = 3/220 = 0.014A = 14mA (when PWM is "on")

>There are three (pwm) sources, but only one ground?
For the "equalivent circuit" you posted, ground the three negative sides of the supply to show a valid circuit.

>>1311528
>>1311529
Thank you!

>>1311529
When you say ground the negative sides of the supply, does this mean i can just connect the negative side of the voltage sources to one another then connect the led cathode to that common negative line?

>>1311532
No. That was just to make the circuit work with a battery as drawn.
In reality, replace the batterys with arduino pins.

>>1311529
It's an RGB LED, so I can't imagine that they're all 2V.

so i had my first experience with a grinder today. had to cut a structure of pipes in the garden, the work didnt come out very clean but that wasnt the main point anyway, the job is done so that's ok
pic related are 2 discs i used, did i overuse them? underuse them? they were 125mm and now roughly 105mm, changed them when i started feeling the grinder shaking, as other people said here. they really dont last much, probably 2 pipes each, thankfully they were very rusty so once i could dismantle them a bit i could break them just with the right lever
a few times the grinder gave me a good rebound, as if it got stuck, did i do something wrong? was cutting too deep? should i be the one moving around the pipe instead of forcing the tool deeper from one side?
thanks in advance

>>1312291
Looks more like a grinding wheel than a purposeful one made for cutting

>>1312295
it's a cutting one, i asked to the guy in the store and the label said for cutting
it's a 3mm thick one, people here said thinner ones are easier to break so a noob should avoid them for a bit

>>1312291
those cant be the right discs for cutting, i've never seen cutting discs fray like that, they look like narrow grinding wheels

UART question. Chart on left is typical AVR for 16 mhz. Chart on right is cheapo bluetooth HC-05.

The fastest rate supported by both is 57600 which has 2.1% error on AVR which is not great, but seems reliable. But it's too slow.

Does anyone know of affordable solution to use the faster BAUD rates of the HC-05 with the 16 mhz AVR? That AVR clock rate is desirable because Arduino UNO and MEGA run at that rate and are inexpensive.

Am I doing this right?

I bought some electrical equipment, and it came with a cord that was not attached. I have absolutely zero experience with, or knowledge of electric wiring stuff, so I'm worried it'll burst in flames if I plug it in. The only instructions it had was that sticker on the back of the lid...

Safe to plug in?

>>1312875

what country?

>>1312881
Does it matter? Either way, Finland.

>>1312886

It doesn't matter to me personally, but different places in the world have different color codes.

It's still a bit confusing. the sticker clearly shows L (line, meaning voltage), ground, and N (neutral) which should be brown, green/yellow, then blue, (according to my pic) which is not like the motor side.

I'm pretty sure your brown wire is wrong since they show no connection there. The question is whether the blue goes there per pic related, or should the blue line up with the motor blue.

>>1312891
>The question is whether the blue goes there

and by "there" I mean the N on the sticker, which is empty in your "after" photo.

It's good based on cable colors and the motor diagram, that's how you wire a 1 phase motor. But looks like there's a mistake on the sticker, it should be L=brown, N=blue.

>>1312875
I wouldn't plug it in because it's clearly wrong, your brown goes to motor black like the diagram and sticker says. Just because colors match you don't get to make the rules up.
Ideally swap brown and blue also if Brown is live. Capacitor generates lag (?) So Maybe Best to match the phase polarity

>>1312875
I'm pretty sure this is how you're supposed to connect it

>>1312899
stop talking like a retard
>Just because colors match
that's the whole point of the colors you imbecile
>>1312900
based on the sticker, which might not be correct
>>1312875
>I bought some electrical equipment
what you stupid faggot, the sticker looks like bullshit

>>1312896
>that's how you wire a 1 phase motor

is that correct, that the line goes to the capacitor? I'm not a motor guy, but web has some images like pic related where N goes to the cap.

does it simply change the direction? Finnbro might need to follow the sticker to get the correct direction if it is affected.

>>1312901
>the sticker looks like bullshit

1. plug per the sticker and kill motor. they will replace.

2. plug per 4chan experts (not per sticker) and kill motor. buy another motor.

>>1312903
You can connect the capacitor to N. The only important thing is that the cap is on the starter winding.
But why would the wires be mismatched?

>>1312891
Yes, it's really confusing. I think what the sticker represents, is the cables that are already screwed in at the "before" picture. They match perfectly, at least. And they have a black wire too, unlike the unattached wire.

Anyway, since this is getting conflicting answers, I think I'm just going to email the manufacturer and ask for instructions. Good thing I'm not in a hurry.

>>1312908
>the cap is on the starter winding.
>But why would the wires be mismatched?

the cap came pre-wired, I think. "before" was before he did anything.

as I asked, does it change the direction of rotation? if so, then the sticker makes sense, and brown goes to L and blue goes to N, ignoring the colors on the motor side.

>>1312912
>does it change the direction of rotation?
Starter wirings aren't meant to be on full load, they would burn. But it would change the rotation but we don't know what this thing is since he's such a faggot.

>>1312916
>since he's such a faggot.

maybe you should check your privilege.

>>1312875
WTF is this thing that OP can't tell?

Nevermind! >>1312900 was correct. After referencing the color coding in >>1312891 pic, it made perfect sense. I changed the wiring, plugged it in and it worked. Thanks my dudes, and am I glad I didn't go plugging it in before asking...

You are rustling my fucking jimmies now dickhead, different colours mean different things in different countries. China,where this was probably made, doesn't give a flying fuck which color means what to you.
The diagram, the picture of the sticker, the actual sticker all agree with each other, >>1312900
This guy is on the money in my opinion, just as i explained first time round maybe if you weren't too busy with your head up your asshole you could tell us why that's not correct.
If you all want to sit around working out which wire goes to which coil fill your fucking boots but the instructions are abundantly clear. Anyone confused by the diagram don't go into electrical as a profession you won't make any money fannying around all day

>>1312922

The colours aren't 'wrong', there is nothing to dictate that a manufacturer has to follow any regulations whatsoever in the colouring of their wiring. In this case it might be unfortunate but the label and instructions agree with one another quite clearly. If the instructions hadn't noted the colours then I could see a possible confusion. But they do.

I'm hanging a dartboard from a wardrobe door, and I want to put a ring of material around the board to protect the wardrobe from stray darts.

What material could I use that would stop a dart from damaging the door without looking like complete shit?

Yes I know there are solutions you can buy but I want to /diy/ it

>>1313593
Get a 2foot by 2foot piece of lexan.. door shows through and should stop a dart without issue... hang it with 2 straps on the top that you can throw over the door top tied to a counterweight... put felt on the back of the lexan behind the dartboard to keep it from scratching against the door and the dartboard will hide the felt...

Does this TV have a sound card?
If so, where is it, and are there other chips/whatever that relate to audio?
It's an LG 32LE5400.
Thanks in a van.

>>1313762
No, no sound card. TVs aren't that discrete anymore.
the board on the left is the power supply. On the right is the motherboard for everything else. If the problem is in that board, the whole board will need to be replaced.
That TV has fucking RS-232 control, that's amazing. Fucking nobody has that anymore and it's incredibly useful if you want to do any kind of automation with the TV. And not just the basic shit either, every setting is controllable through that port and the protocol is described right in the manual.
Even high-end professionally installed media systems use IR emitters because so few TVs have that.
Hold on to that TV anon, you'll never find another with that feature and it's really nice.

what's the audio problem? I'd be surprised if it's actually a problem with the motherboard, it's probably something more simple. Checked all the settings?

>>1313762
Best bet is to trace the speaker wires back to the board and hope you can see a broken part. My TV had a broken control circuit such that it always thought random remote buttons were being pressed, could never find that problem.

Otherwise get a replacement board (no longer available for my model) or see if you can get a compatible board to turn it into a monitor.

>>1313798
Very insightful reply, thank you.
Which part(s) is the RS-232 control?
What kind of automation are you talking about?
I'll have to check this out, we got a new TV anyway so this one's mine to tinker with now.

My guess was the motherboard (now I know there's no sound card).
While TV was playing normally heard a sound like a headphone jack being ripped out, then sound went out. Reset audio, changed all the settings, turned TV off completely, tried multiple devices to input audio, Roku, cable, laptop, etc. Tried different cables, settings, sources, everything I could think of. No audio using the audio out port with headphones, so it shouldn't be a speaker issue.
I did tech support for a few years so tried everything, so I was pretty confident it was an internal thing.
>>1313803
I was considering that. Might try it, I've been googling the numbers on the chips to see which ones relate to audio and if I can get a replacement, that'd a pretty guess-and-check method though as I don't have any kind of testing equipment.

>>1313806
The RS-232 is the 9-pin connector next to the VGA. Automation as in using a computer to control the TV. There's not as much of a need for that with a smart TV of course, but some people have complicated media systems with many video sources, or the TV is on a lift that drops down from the ceiling or comes up out of the floor, and they control it with one big remote or an app. there's a controller that switches the TV's input, powers on it and whatever device the input it set to, operates the lift if there is one, all with the one button press. Mostly it uses little sticky LED emitters that emulate a remote control in order to control the TV and other devices, but that only goes one way (there's no confirmation that the tv actually received the command). RS232 is nice because it's absolutely reliable and the system can make sure the command was received and take some action if it wasn't.
it's a niche case, admittedly, but having an RS-232 is fun if you're into programming and want to tinker with it. Arduinos, raspberry pis, some HTPCs and most older laptops/workstations have native RS232 capability.

so you've been thorough, it's not a good sign that it just suddenly cut out like that. it'll probably be hard to diagnose because that's a complicated and intricate circuit board, even if you tried to work backwards from the speaker wires and probe with an oscilloscope you might not be able to find out where the problem is.
Check all the wires, make sure there's no shorts, look for anything on that board that's scorched or bulged. If you get nowhere, you might check ebay for a new motherboard, or a takeout, or a cracked TV of the same model that you can pull the mobo from.

>>1313813
Interesting, I'll have to look around and see if I can make anything useful with it.
I used to have a Raspberry Pi, but never did much with it, and I've done a very small amount of Arduino. I'm guessing I could get a USB to RS232 adapter and control it with my computer. Might be some interesting projects I can do using it.
I'll take a closer look and see if I can find anything that looks damaged, I have some spare wire and soldering equipment so hopefully the if that's the problem I can fix it easily. What kind of testing tools could I use, would a voltmeter or something similar be appropriate? I know the basics of electronics but haven't done anything too hands-on in a few years.
I'll check if I can find some for cheap. One with a cracked screen is a really good idea.
Thanks, this is great info!

>>1313762
Here's an educated guess, and esay to do. Replace the big-ish electrolytic capacitor that is around the power amplifier chip. Often they dry out and lose capacitance. Same happens a lot on the power supply of the tv's

>>1313821
Sorry to be spoonfed, but can you be more specific on which one it is?
I've located the audio amplifier chip. Would the power amplifier chip be something that only affects audio as well? Every other function of the TV works fine.
I may as well try that if I can find, shouldn't be too difficult.

>>1313819
If you want to really troubleshoot that board, you need an oscilloscope. A voltmeter is a stick you can use to poke around in the dark-- A scope is like having night vision. But you can get pretty far without one.
http://www.conradhoffman.com/troubleshoottut.htm
this guy's guide on troubleshooting is a pretty good read.

>>1313830
Before I read that (I'm the other anon whose tv broke), what tends to go wrong in these control boards? Would it be the passives, the small transistors, the small ICs or the big ICs?

>>1313826

I can spoonfeed you all you like.
The power amp chip does audio and nothing else. Should have ONE big electrolytic capacitor near it. Try replacing that (soldering skills necessary. Anything that is in pairs around it, do not touch it ( I am assuming it is a Class-D thing)

>>1313712
Watts is the deciding factor, but look at led bulbs... they’ll be advertised as “equivalent to a x watt bulb” but also will put the real amount of watts they draw somewhere on the package... they draw significantly less watts than incandescent bulbs... I brightened my kitchen by getting 4 60 watt equivalent led bulbs that actually draw about 2 watts each (making them safe for the sockets and circuit) and replaced 4 25 watt incandescent bulbs... brightness is rated on the bulbs box in lumens... I about doubled the brightness in my kitchen... do know that led bulbs take a special dimmer control so if your light circuit has a dimmer and you put leds in you’ll have to change it..

>>1313863
Alright, I'll check that out, thanks!
>>1313830
That's a good read, I'll definitely have to look into getting an oscilloscope, I run into problems all the time where I wish I had something like that.
Thanks for the help, anon, it was great.

How the fuck do you solder with a torch? I'm heating stuff up and feeding it solder but the solder just beads up and falls off. What few times I can get it to stick, it just pops right off at the slightest force.

What am I doing wrong? I'm using 1.0mm 1.8% flux tin solder.

i want to use a pair of couplers to give my air compressor output a 360 degree swivel where each one gives one axis of rotation. i know there are swivels like this already but every single one has shitty 1/4 inch ends that have shitty 1/8 inch orifices and are barely good enough for a tire inflator. would this work out or be a waste of money?

its pretty thick solder so i figured it could be the solder itself and not the torch or shitty irons i keep buying that instantly break

>>1314521
>its wires but i wanna be able to braze things together
the flame from a torch quickly oxidizes the wire because they're thin - assuming it's stranded wire
plumbing heats more evenly and slowly due to mass
also, flux is always added for good plumbing joints to that ensures nice flow of the solder
keep the torch for brazing and plumbing soldering and get an iron for electrical work

If it weren't, industrial produce wouldn't be done in dirt

hydro/aqua/aero ponics is good for when you have severe space considerations but dirt is just easier and offers the same level of nutrition for the plant while also not requiring tons of extra work to keep the balance of your water medium just right.

If you're just growing berries or something, just do it in dirt. hydroponics is for weed, aquaponics is just a fancy granola/hippie/numale way to produce manure at home from fish instead of horse/cow poop, and aeroponics is for desert people who dont have enough water for farming.

I'm not sure if someone is getting memed on here but this actually works for getting permanent marker off of stuff, especially whiteboards.

If some fucker in the office used as sharpie on the whiteboard and it left a stain, scribble over the mark in more sharpie and IMMEDIATELY wipe it off. permanent markers have alcohol in them, it's how they stay wet and then it dries off almost immediately. after that then you can use alcohol or bleach or whatever for any faint marks that remain.

likewise, "whiteboard cleaner" is usually just alcohol and/or acetone. what i do at home is just mix normal rubbing alcohol from the pharmacy or dollar store with a couple drops of dish soap and it's a FANTASTIC all purpose cleaner that's still gentle enough to not strip finishes or discolor fabric.

If it does not sag there's no need to replace it. even if some joint tape pops loose you still just fix that.

and don't forget to ask the guy at the paint store to shake the paint if it's something you got off a shelf. Otherwise they give you a stir stick and assume you have an hour to stir it at home. That way they will know you are a pro.

If it's an induction motor (runs off AC, has no commutators, and has no permanent magnets) then you need to drive some power into its winding(s) before you can generate anything. If it's a brushed universal or DC motor on the other hand you can use it off the bat, and if it's a brushless DC motor you may need to swap the polarity of some transistors and add a power source for them.

I have some small traveling headphones to fix since cables are usually pretty bad quality and they snap like a string. Since I do small repairs like that for people rather often I thought I should stack up on some proper cables with minijack. Do you guys know anything trustyworthy like that? Something I can just order a bunch from Amazon?

I want to make a cheap Kirby figure. What what you all suggest to use for a base? I was thinking of a plastic ball, but not sure what kind.

>>1316210
Off hand I can't see how it would be that hard, just use a flat screw driver or something, possibly with a mallet, to align the metal of the pin straight with the hole. Then use a punch, nail with the point filed off, or something similar that will fit into the hole to push it through. Might need the mallet there as well.

If you can turn the screw slightly at all it might help if the hole is not lined up perfectly with the dip in the crown nut.

If it's not that easy I have no idea what's going wrong, so good luck...

Dremel is what you need.
Or maybe drill out both ends and tap the pieces trough, you can always get a new nut.

Is it more efficient to have wide temperature swings, or to keep close to the setpoint temperature?
For example, is it better to turn the furnace on at 60 and let it run until it hits 65, or to turn it on at 63?
I'm thinking that for a given outside temperature, there's always a constant rate of energy being lost to the outside. The lower the temperature difference between inside and outside, the slower the energy is lost. So a house kept at constant 65 degrees should lose more energy than if it were bouncing around between 60 and 65.
Is that right, or does it work out the same?

>>1317376
>The lower the temperature difference between inside and outside, the slower the energy is lost
This is correct. The relationship is linear for practical purposes. So the time-temperature-difference curve area is what matters for heat loss. So for example, bouncing linearly between 60 and 65 degrees has the same heating budget as a constant 62.5 degrees. To minimize heating costs, find out the minimum temperature you're reasonably comfortable at, and keep it there. Some thermostats let you set a schedule with different temperatures. So you might set a lower temperature while you'll be out at work to save energy, and have it turn back up an hour before you get home. However, this scheduling typically doesn't work efficiently if you have a backup heating system that kicks in if the main (extra-efficient, e.g. solar or geothermal) system isn't enough, because the change is typically larger than the backup activation threshold.

>>1317382
I'm going beyond a programmable thermostat, I'm making my own thermostat. I've got sensors in multiple locations, and depending on the time of day, occupancy, and outside temp, it changes the setpoint and also which sensors it uses.
I also need to know if there's any efficiency difference in the amount of time the (gas) furnace is running. It's probably not efficient to start the furnace and run it only for thirty seconds, but I don't know what the limits are, the furnace's manual says nothing about that. It usually came on a few minutes at a time with the stock thermostat. Since the thermometers I'm using are a lot more sensitive, this is something I've got to consider.
I've had this system running a couple of days, I'm collecting a ton of data to graph out so I can get a handle on this.
the way I have it set now (and with how cold it's been recently), it runs about two minutes every 10 when I'm home, and about three minutes every 20 minutes when I'm out or asleep.
About 45 seconds of that runtime is warmup, but it's followed by about a minute and a half of cooldown with the fan running, which the furnace does automatically.

The metal has probably mushroomed on both ends. The notch may be enough in the way to work against you. Small punches and maybe drilling it out with a stronger bit?

>>1317543
>>1317555
More to the point, adjusting the armature looks like it would put a lot more stress on the screws than just the weight. Anything but the cheapest drywall anchors (like the ones in the image) should be plenty. The screw-in plastic type would work, and proper molly or toggle bolts would, as the other anon mentioned, be stronger than the plasterboard.

>>1317580
>I also need to know if there's any efficiency difference in the amount of time the (gas) furnace is running. It's probably not efficient to start the furnace and run it only for thirty seconds
A heater is not like an engine. It does not have to extract mechanical energy from the heat, it just has to generate it. Supposing that the furnace doesn't lose a puff of unburned gas at startup, any loss of efficiency is probably more to do with ventilation and heat distribution than the furnace itself. And that's where quickly turning on and off may run into problems. Electric motors consume a rush of current as they spin up, and depending on the particulars of your system, that may impact the electricity bill at some point (though the extra heat generated would slightly offset your gas use). It also places electrical and mechanical stress on the fan, which could shorten its maintenance interval. Also, there isn't much point in having the cycle time be significantly shorter than the time it takes the temperature to fluctuate noticeably. It wouldn't make a difference in perception, and your house's insulation will smooth out wobbles in temperature as the heat passes through it (so the total heat bill wouldn't change). The current timing is probably fine, but if you're not noticing temperature swings, you might consider increasing the activation threshold so the furnace cycles are more like they were with the stock thermostat. At this point, efficiency differences will probably be tiny, and would depend on the particular details of your system. There probably won't be public documentation with that information though. Do you have the contact information of the company that made/installed your furnace?

>>1317675
>It's probably not efficient to start the furnace and run it only for thirty seconds

if the furnace has been off for very long and is in a much cooler environment, it has to heat itself first before usable heat can be delivered to the living space. so yes, in general any furnace that burns fuel will be more efficient if it runs for a while. "a while" depends on many factors, however.

>>1317675
No I've got no contact information, I just was able to find the install/operation manual for the furnace. It's an Ameristar (rebranded Trane) 40k BTU.
The way I have it set up is with a setpoint and overshoot, it kicks on when the temperature dips below the setpoint and runs until it rises above the setpoint plus the overshoot value. Currently I'm running 3 degrees of overshoot when occupied and 4 otherwise.
Much less than that and it cycles very fast. The thermometer in the stock thermostat is a chip attached to the board, attached to the case, attached to the wall, so it responds slowly to changes and holds its heat a long time. It's right next to a vent, which heats up the thermostat and the wall it's on, so the rest of the place stays pretty cold unless I crank it up. That's one problem I'm trying to solve.
My thermometers are in a TO92 package hanging free in the air, so they respond very quickly to temperature changes, it would cycle very fast if I didn't have the 3-4 degrees of overshoot.

Just bought a 50s house, plaster walls ceiling and wood floors. Tell me if this is a good or bad idea:

Strip wall paint down to plaster, do a subtle color wash. Skimcoat sand and paint ceiling white. Refinish wood floors and stain dark.

Or should I just skimcoat and paint the walls too? They are fucked now, I figure equal work to do either option

>>1317694
>it has to heat itself first before usable heat can be delivered to the living space
Except that here >>1317580 the furnace is mentioned as cooling itself off after running via the fan, so any extra heat from warming up would get extracted and moved to the living space anyway. And with the furnace presumably being inside the house, it's not like the heat stored in the furnace would go to waste.

>it's not like the heat stored in the furnace would go to waste.
Actually in my case, it does go to waste. The furnace isn't in a conditioned space, it's in an attic.
I guess in a way, if the attic is warmer, less heat is lost from inside the house, but still heat from the furnace does not go into the house directly.

I want to build a coffee table with a hidden compartment. The table should be no issue, but I have no idea where to start when it comes with the hidden area.

Does anyone know of any resources that could show me how to build one? I have tried google, but all I come up with is pininterest crap that does not show you how to build it.

>>1317899
I'd start by looking at what sort of door you want. There are cabinet doors that are just a flat panel that you push in to unlatch them; adding a stronger spring inside one of these might make for a well disguised door. I imagine similar things exist for drawers. Flush hinges are pretty common, but you may have to buy a couple of different sorts and experiment to see which ones let you minimise the gap between the door and its surroundings.

Putting the compartment itself on the tabletop is ill-advised, going for a small corner underneath or inside is probably what you'll have to do. You need to prevent it from rattling if you accidentally hit your shin on the table, and prevent it from opening unintentionally. There exist magnetic locks for this sort of thing, where you hold a magnet up to a part of the cabinet and the door opens, but making a robust and well-hidden door with this may prove difficult. If you do go this route, a reed switch will work as the magnet-sensor and will be very easy to incorporate into some part of the table, so all you need is some sort of flush locking mechanism that can be opened electronically. You may want to investigate RF energy harvesting for this as it's unlikely that you'll be able to leave any old cheap battery inside the table for a decade or two.

>>1317874
>heat from the furnace does not go into the house directly
The furnace will have a time or temp (or combination of those) device that keeps the air mover blower running after the flame goes out.
This allows recovery of the latent heat accumulated during burning to be distributed into the living area.
This same device withholds the blower operation until the furnace has accumulated enough heat so as to not distribute cold air on restarting of the heating cycle.
The air mover blower is separate from the draft inducer fan which cycles more closely with the actual flame cycle.
Older furnaces may not have a draft inducer fan.
