/diy/ - Do It Yourself

I bought a Hino Dutro box truck for 10k and am in the process of building a camper. The back is 2.1m high, 2.1m wide, 4.5m long. In that I was able to have a composting toilet, recirculating shower, kitchen with sink, microwave, induction cooktop (with thermal cooker to save power), dish drawer dishwasher which is also storage for dishes, 170L Samsung inverter fridge, Companion twin tub washing machine, foam bed cut to fit, and lots of storage. I used the RackIt 1000 from Bunnings to build everything quickly.
You have to make things convert from one use to another. For instance I have the toilet in the front left corner just near the side door. This is an entry where the floor is the waterproof shower floor. When I close the outside door and open the toilet door to the right, the entry becomes the shower area with the toilet on the side. This bathroom is also the laundry drying room with heaters and folding clothes line. The washing machine sits under the kitchen bench which has the induction cooktop on top. When I want to use the washing machine I lift up the kitchen bench. The electronics bench is above the computer desk. So if I'm standing I'm at the electronics bench and when I sit I'm at the computer desk.
I definitely advise insulation - the cheap styrofoam is best and use a bit of expanding foam in the gaps.
I've got a 240v portable air conditioner which sits in an underbody storage box with the top where the cold air comes out sticking through a big hole cut in the floor. And I use an DH30-M12 hydronic system from DieselHeat for heating air and water and the truck engine ties into this too. This can also heat engine and fuel lines for starting in snowy areas.
There's 5 x Trina TSM-500DE panels going to a Victron EasySolar2 5kVa with 48v lithium and everything runs on 240v with Commodore CD-6500 auto-start diesel backup generator.
Water is collected from roof and drinking water goes to a Viqua UV1 system.
Only fuel is diesel - no LPG or unleaded.

Go to a doctor. Neurologist. They can surgically reduce or eliminate the neural signal that causes your feet to sweat.

I know this works because my brother-in-law suffered from sweaty palms and was cured this way.

What's your budget?
Are you a hermit?
What's your time frame?
As for being 100% up to code, that'll be tough for an old house. Much easier to build new, but then you have to demolish the old house and dispose of it which is harder than it first seems.

Inverting to AC to drive a purely resistive load is wasteful and expensive.

Replace the heating elements with ones appropriate for 24 VDC.

For example, if your toaster oven consumes 1kW, since Watts = Volts x Amps, by dividing both sides of the equation by Volts we get
W/V = A, so 1,000/24 = 41.7A

Volts = Current (in Amperes) x Resistance (in Ohms), or V=IR (I=current),
solving for R, we have V/I = R,
so 24/41.7 = .575 Ohms.
So look for heating elements that add up to
somewhere between 0.5 and 0.6 Ohms.

Is this related to CO2 blasting.
In CO2 blasting, dry ice (solid CO2) chips are propelled with air or nitrogen against a surface, and the CO2 sublimates to CO2 gas, leaving no residue.

Is this natural gas or propane? If it's natural gas and is supplied by a utility company, call them and someone will come out and do a safety check and show you how to light it or do it for you.

Just remove it. As long as you don't care about the way it looks, the vent grille isn't actually needed.

How do you plan to load the program into it?

Probably best to start with a serial terminal emulator like Putty on a PC or Gnome Terminal if on Linux. Still need a UART chip to convert parallel bytes to serial bits and vice-versa.

The Brymen BM235 Multimeter looks just fine. If you're willing to spend the $125.00, it should serve you well for many years. If you do buy it, don't leave it unused for long periods (three months or more) without removing the batteries since alkaline cells tend to leak once they are fully discharged.

Don't waste your time on an ICE (Internal Combustion Engine) bike. Go electric!

I've got two EGO line trimmers and one leaf blower and two of the matching 56 Volt batteries. Everything works well. Typical runtime weed-whacking is about 30 minutes per battery.

Eye protection is most important. Just the reflection of the beam off a distant object like a door handle and back into your eye can cause eye damage.

Water is the enemy of every house.
Look everywhere regularly for leaks.

Know where your main water shutoff valve is and
make sure you can open and close it quickly and easily.

Create a grid plate from plywood, metal, or plastic or metal to hold a N x M grid (array) of pots such that they are facing up and nearly touching each other.

Lower a wire mesh screen with 2-3 mm diameter wire and 25-50 mm wire spacing over the array of pots. Use welded stainless steel wire mesh for the best results.

Dump soil over the screen, making sure each pot is overfilled.

Strike off the excess soil using a board/scraper made of metal, plastic, or wood.

Remove screen.
Remove pots.

Repeat as needed.

Unless you're working way out in the field away from electricity, you should be using a battery powered electric chainsaw, not a noisy, finicky, polluting two-stroke gasoline one.

From a 60+ YO small business owner:
This is a great opportunity.
1) Show up on time each day
2) Pay attention.
3) Take notes. Keep an old-fashioned notebook so you can write stuff down and draw pictures.
4) Put safety above all else. If you have an accident, everything will go to hell.

I suggest starting with a table that has straight legs like this.

I would use a bare-bones arduino clone like a Adafruit product #123 AtMega 328P pre-programmed with bootloader. This way you can programattically change the behavior, add time delays, etc. to fine tune your design. Yes, the price of the analog solution may be less, but you'll spend a lot more of your valuable time trying to get it to work than with a microcontroller.

Unskilled, illegal alien day labor earns $15-$16 / hour here in San Diego.

Ask for a $1.50 per hour base rate raise now, then again every six months until you are up to at least $22.00 per hour.

Keep learning new skills, and stay safe. You can't earn if you're broken.

Broken includes general health, so work on improving your diet, eliminate bad habits, etc.

May be a shorted electrolytic capacitor on the final amplifier stage.

Use more oil, then soap. Oil should be canola, olive, peanut, vegetable, etc.
Don't use motor oil or any petroleum products.
Rub the oil into the stained area. It's OK to cover a larger area than the stain itself.

Wash out with dish soap and warm water.

This is a schematic for a clock or perhaps just a counter IC. The lower section is a bunch of counters and the upper section left/right are 7-segment decoders.

Dish soap. About 10 drops for an average sized sponge, and hot water. Squeeze sponge repeatedly to make bubbles/foam. Rinse in hot water. Leave a bit of the dish soap in the sponge to act as an antibacterial.

I used this type of drill for many years. I still have one I got more the 40 years ago. Do I still use it? No. I have several Ryobi electric drills with lithium batteries and they work much better.
