I'm looking for plans and ideas for a woodstove type heater for a 12x14 room. I've seen random bullshit posted in forums and YouTube. Can't make sense of any of it. I've also come across rocket heaters/stoves that are shown as the next coming of Christ but to me feels like a gimmick. What I'm looking for is tried and tested plans that don't burn your house down don't kill you in your sleep due to CO poisoning. And those could be either traditional stove type or rocket stove type. Also something that would burn efficiently without using a shit ton of wood. I need to burn it mainly for sleeping as I have a traditional mass heater in my living room. Any ideas ? I can weld and have access to basic metalwork tools, nothing fancy.

Not DIY, but a heater.
I want an infrared heater that is small, portable, quick to turn on/off, emits directed heat, and would be safe to place e.g. on a couch.
Most IR heating panels will do what I want, but they are at least 60x60cm and are often supposed to be mounted on a wall with no convenient way to place them in random locations.
Some panels have retarded non-directed design, i.e. they radiate heat at the front and and the back.
Heaters like pic related (this one have a marble slab inside) accumulate and release heat instead of just emitting it, so you can't just turn it on and get instantly cozy.
Any recommendations?

A spiral wound heat exchanger with the tea/soup pot out of the fire could be folded out of one piece of sheet metal with crimped/brazed seams only on the outside. Since liquid holdup will be too low I either have it flow through once or it could recirculate using a thermosyphon or steam bubble-airlift pump.

>The best diy 3d printer?
Probably a hot-rodded Voron tailored to your specific use case.

>Which is the least expensive and smallest to make?
This is a very different question. The usability of cheap purchased printers and the time need to DIY means that DIY printers are mostly aimed at higher-end markets (e.g. Vorons). Some Voron Zero kits are fairly cheap (though more expensive than many ready-made printers).

How would you go about painting/refreshing this screen door? Would painting just clog the holes?
7 replies omitted. Click here to view.
>>
>>2896037
That's not normal/typical woven screen, looks like thin metal sheet with holes punched in it. yes? If so, use a pressure washer (or maybe even a sand/media blaster if you have access) to clean it up and remove any old loose paint. Then use spray paint, using multiple quick pass coats so as not to have any large amount of paint that can accumulate in the screen holes.
>>
>>2896037
Buy a quart/gallon of isopropyl alcohol. Use that to scrub it down good with a Brillo pad or steel wool.

Lay paper under the door, extra few feet each side.

Paint it with a roller, GO SLOW. Keep it controlled and you’ll have less mess than spray painting.

If you use the roller tray correctly you can make sure you’re only laying down thin layers (and let them dry! Wrap the roller in a grocery bag to keep it moist). This will prevent drips & clogging any mesh.

On closer look that has a bunch of rust. Spend the extra on a rustolium style of paint. It’ll look & last longer.
>>
>>2896037
Go over it with a wire wheel or brush to knock off all the loose stuff, hit it with some rust converter primer, then give it a couple topcoats in whatever color you want. Make sure all the paints are the same kind, though. Oil and latex or whatever don't mix.

Hey lads...

I'm in a bit of shit. So recently my washing machine broke and it turned out to be the belt that had fallen off... the belt fell off because the bracket that holds the motor broke. Got a guy in to fix it because I had to work and he basically nigger-rigged a fix by drilling a hole in the bracket and putting a bolt through it to connect it back to the casing. Question is, this isn't fucking lasting and the belt has come off again. I can't afford the laundromat or a new washing machine and doing it by hand fucking sucks and I don't have the bath to wash it in. Pic related is kind of what it looked like before drilling the hole. WTF guys, is there anything I can do to fix this? What a crappy fucking design. Plastic shit! Planned obsolence is fucking screwing us out of pocket.

A little heat on the pulley around the shaft never hurt eithe.

If there’s a set screw and it’s not press fit, also gonna rec the heat because loctite on those little hex set screws is a bad time.

A few days ago I posted on /g/ about how my Edifier r1700bt speakers shit the bed. A /g/ent suggested posting here in hopes someone could save me from having to toss the whole thing away when it might be an easy fix.

I can trace the audio running through my setup all the way to the composite cables that run into the speaker - all of that works fine and I can hear the audio if the cables are plugged into a separate speaker setup, which tells me the problem must be in the Edifier speakers themselves. When I take it apart, I don't see anything that immediately jumps out to me as wrong (though, to be fair, I have no idea what the fuck I'm looking at).

Help?

couldn’t you just convert into into a cuckshed and make a monetized youtube video about how you turned an old boat into a “tiny home”? That’s what I’d do.

I get a ton of building supplies and construction materials from demolition, remodel, repair & replacement at my job. domestic violence and drug use has provided us with up to 20% of the construction supplies for projects on our farm. we're talking literal 10's of 1000's of £/$/€

this steel entry door is exactly what we were needing for the livestock barn/shed expansion we are working on now. $500 knocked off the project buget! I was even able to make the needed repairs while on the jobsite, so essentially got paid for repairing & loading to take home.

what are your best acquisitions? what are the resulting projects & estimated savings?

I took apart a stick frame garage/barn and part of a house that was slated to be demolished.
Years later, Ive turned it into a 500ish sq foot house. Worked in solar shit a few years for access to machines, ended up off grid totally on impulse too but it was basically as easy as actually hooking in; my panels are bi facials with cracked rear glass from next to the suppliers dumpster

Preciate the kind words.
It was a pivotal moment, standing on the roof of a 3 story building, having just walked thru it all, faced with the fact that... it was getting fucking landfilled. Unsure what "go for it" meant. Unsure if others knew I was a savage actually, unsure.... if I was actually a savage or just a dreamer. Just knew that man, that wind you could fuckin feel that wind. It put you right there. Does it make sense to work hard as hell to save someone else on dumpster fees? Like, doesnt make sense to take it apart it you cant put it back up. Mom was not a fan of the idea.

Ill never forget the feel of the wind on my face up there. I was between jobs, had like 2k ish I think. I decided if I didnt, I'd always wonder.

Those things are terrible. I’ve used them on a toilet paper holder and that’s about as far as it goes. The main appeal to them is not having to drill, but they leave a fuckheug hole and seem to hold less weight than pluge because they crumble the drywall while going in. Also they never sit totally flush, best you can do is like 1/16” off the wall, which hurts the strength more when you want to hang something that should butt up to the wall for support.

I want to get a shed in my yard to use as an office since my house is pretty small but I have a ton of land.

Now I am wondering if buying materials and building it myself would actually be cheaper than prefabs.

Obviously there is no upper limit to how expensive and intricate either can be but I'd like to keep it under 8k. The only thing I really care about is having enough room for a desk and for it to be waterproof. Windows would be nice too.

I am a construction worker and have worked on pretty much every part of house building but I'd be doing most of it alone.

I just feel like by the time I buy all the material for a small shed I'll be in the range of 10k anyways since I don't have the ability to bulk buy from cheap sellers like prefab makers.

>Also a great built. How weather resistant have you found it to be?

I built it to be well ventilated since my old shed sank into the mud and rotted. It has soffit and ridge vents and i probably over ventilated it for the hot months.

I have been in it quit a bit this winter with a kerosene heater but i plugged off the ridge and soffit vents to try to retain heat better. If it;s in the 40's the kerosene heater can get it about 60*. But if it's a very sunny day with sun coming though the windows it can get it up to 60* without the heater on. If it's colder than 40 i usually don't bother trying to work in it.

Hey /diy/,

My current job involves a lot of designing and building control systems for machines, something I came into the job knowing nothing about. I've done a pretty good job of getting up to speed, but I'm constantly finding out about better solutions and hardware and best practices that I wasn't aware of.

Given that I have no formal education in automation, does anybody know of any good resources for learning more about the hardware side of things? I'd like to step my game up.

If so, you know practically everything you need to get a job as a PLC programmer. There's some other stuff you should learn, like how to use power control modules to control motors and solenoid valves, or how to connect a PLC to a network, but you can easily learn that on-site (either with the aid of a helpful mentor or watching YouTube video tutorials made by Pakistanis), so you really don't need a lot of math or knowledge of electromagnetic theory. If you don't know the bare mininum, I'd suggest at least taking a course or two on Basic Electricity and Electrical Machines at your local community college. I got my practical lessons on electricity when I had my first job, all taught to me by an extremely patient mentor, and eventually decided to learn other topics on my own, mostly from books and online courses.

Several plumbing supply places say there is no flush clean out cover for this type of PVC, which is 4" DWV. They only make them for the belled end, which seems ridiculous.

Any good ideas on how to unfuck this?

We run across this all the time.
Chisel out around it, cut it off, and glue a threaded flange on it, then back fill it with concrete.

Although, I might back fill it with something else. Concrete shrinks a bit, you don’t want it to crack. You could pack it with caulking mixed with sand or something, as long as your excavation doesn’t look like a dog trying to exscape out of the backyard under the fence.
