Welcome to /diy/, a place to:

Post and discuss /diy/ projects, ask questions regarding /diy/ topics and exchange ideas and techniques.

Please keep in mind:
- This is a SFW board. No fleshlights or other sex toys.
- No weapons. That goes to /k/ - Weapons. The workmanship and techniques involved in creating objects which could be used as weapons or the portion of a weapons project that involves them (e.g., forging steel for a blade, machining for gunsmithing, what epoxy can I use to fix my bow) may be discussed in /diy/, but discussing weapon-specific techniques/designs or the actual use of weapons is disallowed. Things such as fixed blade knives or axes are considered tools, things such as swords, guns or explosives are considered weapons.
- No drugs or drug paraphernalia (See Global Rule 1). If you want to discuss something that could involve such things (e.g., carving a tobacco pipe from wood) that's fine, but make sure it's /diy/ related and doesn't involve drugs or it will result in deletion/ban.

Some friendly suggestions for posting:
- First ask Google, then ask /diy/. Your question will probably be better received if you do so.
- List available resources (tools, materials, budget, time, etc.)
- Try to use pictures and explain the goal, if possible
- Be patient, this is a slow board; your thread will be around for days.
- Share your results! /diy/ loves to see problems solved and projects completed!

i ventured into the unknown and shorted every pin to ground one by one.
shorting ant did nothing, however shorting "mpx out" or "afs" cut the received sound and let only the bootleg audio source make noise.

afs gives a better result than mpx (no crackling at the moment of shorting, instant cut of audio,) with a datasheet from a radio module(TDA7540NTR) saying it automatically mutes the module (when 0.6<V<0.8) for something. see pic
grounding afs seems to produce the same result though.
would it be better to drop the voltage (from 3V) to ~0.6V instead of 0V? i myself dont see why it would be necessary, but to protect my already damaged brain i want to keep future potential headaches to a minimum.

So i am open to any wisdoms of /ohm/

>>2260896
Protons are bound into the nucleus, and in solids the nucleus can't move. In ionic solutions and gases, current is carried by the movement of electrons and of positively-charged ions (i.e. an atom with some electrons removed). Even then, most of the current is carried by electrons because ions are much heavier than electrons so they don't move as fast.

I'm rolling Makita now (drill, driver, recip, rattle gun, circular caw, sander) but wish I went DeWalt because the flexvolt stuff looks good.

II hink between the major brands it's close enough that it doesn't matter any ways. Maybe an edge to Milwaukee if one of the extended tool range tools applies to your work.

What would be the best way to build an illegal dwelling in a national forest? How would you do it?

Rules:

1. Must be underground
2. Must be practical. You'll be transporting all material and doing all work in a remote part of the forest.
3. The dwelling must remain hidden
4. The dwelling must be suitable for living during summer and winter

You can use whatever tools and materials you want, given that you want.

That costs money.
Build a wall out of snow (or just dirt) and spray it with water to seal it up.
Add water slowly overnight and it will freeze before it has a chance to go anywhere.
Snow is best because you have nothing to clean up afterwards.

For someone with nearly 0 technical skills. Is HVAC a good place to put my soul into? I have a master's degree in a meme subject (sport management) and can't find a job aside from a stocker at walmart and I have no real skills. I am 27 years old and fear having no skills with fuck me forever, so I wanted to try and learn a trade. I'm too stupid to do math so electric is off limits mostly. I was thinking HVAC because they will always have jobs no? I live in Florida currently. Everyone needs AC. And if I move up north, people need heat too. How should I go about getting into HVAC? Not sure i want to go to school again only to graduate with the same response from employers which is, "that's great to did school and all, but we prefer experience" and I'll be in the same exact spot after school is over on 3-4 years or however long it takes. Any suggestions? Trying to better myself and have some slight hope for a future that isn't stricken with poverty. (I'm debt free currently and living with my mom) so really brainstorming. HVAC seems the most interesting because health and air seems kinda fun and cool. Idk if I'd have to do a lot of other shit but those are what sound good
>>
>>2260960
>always have jobs
Everything always have jobs, just a matter of getting to them

>maths
HVAC will involve electrics and other things so you need maths just like any other, however, also like many other, it is basic level maths, not complicated to pick up

>interesting
Sure but so is lighting, or gardening, it depends on your personal preference

>put soul into
Don't be dramatic
>>
>>2260960

You'll need to have a basic understanding of diagnosing mechanical and electrical, or go to trade school. Computer science is a bonus if you go commercial HVAC. Controls work pays well and it makes you a more desireable hire. If you aren't willing to exchange physical labor for $$$, don't bother going this route. Attics and rooftops are hot in the summer, but the pay is well worth it if you have the motivation. I worked in IT support for 6 years, then went into automotive for 10. Switched to commercial/industrical HVAC and making a stupid amount as a controls tech. I was moved from maintenance to service calls after 6 months, but I'm mechanically inclined and picked up reading wiring schematics fast. If you decide to go this route, absorb everything this guy has to offer - https://hvacrschool.com/podcast/

He is a valuable resource. If you don't care about electrical like you mentioned, go into Plumbing. It's not all shit running downhill. Natural gas, condensate, and other pipe fittings are part of the trade, and they make a good amount as well.

You will actually consider suicide halfway through your first week of tinwork.

What are the most cost-effective construction methods to research and consider for building a 75' (23m) habitable structure that will stand safely for at least 500 years in the absence of structural maintenance? What aesthetic considerations should be made before blighting the earth with such a durable structure?

The structure will be on flat wooded acreage in western Pennsylvania, USA, with construction beginning within the next three years at the earliest. Ideally, it would be designed in such a way as to permit the building of one story at a time, as funding is available, but I can put off the project for several more years if it makes better financial sense to do so. Initial usage will be roughly equivalent to a hunting cabin and over-built hunting blind, eventual usage will be as a residential home. Natural lighting is important.

I anticipate eventually assembling some kind of knowledge archive on the site, so any ideas on that front would be appreciated, as well.

Let's say I have access to as much sawdust as I wanted for free. How can I turn it into a hard form, (log, blocks, etc), that can be burned as fuel in a woodstove or backyard fire pit?

Obviously, I'd need some type of binder that would dry hard, and burn clean, right? Mix, pack it in a form, let it harden, burn it.

Okay, wtf is this? The end is threaded and both clearly and readily screws off. I have the old "classic" non-self igniting one and need a similarly narrow and directed flame. But it doesn't fit on the ts8000 and I can't find different ends for sale anywhere.

Why. I'm working in an enclosed space doing plumbing, I don't need a wide flame blasting everything.

Want to up your game?

The based torches for plumbing are Asco, Goss, Uniweld, TurboTorch etc with hoses and multiple tips. (Cheapest way to wallow in torches is buy used with a bit of study. I collect, overhaul and use a wide variety.) Aiming torches screwed to LP cylinders annoys me greatly.

The designs are ancient with expired patents so parts and regulators and regulator overhaul kits are plentiful.

I'd not buy new at retail prices unless you have work to do immediately (then visit your local welding supply for anal raep). Read about tip sizes and styles so you get the right tips (screw or QD) for a given torch body. It's worth it.

LP and acetylene differ so get the right torch. (I have both and prefer acetylene but LP runs off a BBQ tank if ya don't like paying for the expensive baby cylinders to get pennies worth of LP.)

Classic LP TurboTorch (not mine) with smallish tips at a reasonable Egay price. Check Fecesbook Marketplace too. I buy all my torches used. Viton O-rings are cheap if needed.

Classic Asco torches. Less known but plentiful and excellent. I've a couple of sets.

>>
>>2260082
>the knob on the back controls flame size you tard
No, it controls the rate of heating. At very low levels it kind of narrows the flame, but is nowhere near where it could melt solder. After that the flame size is basically the same.

>you literally bought their high powered model and are complaining it does what it is marketed to do
The flame character is all about the tip. The tip screws off. I'm not sure what your issue is here. I will admit that your post was annoyingly aggressive though, so there you go I guess.
