Hey /diy/, has anyone tried making their own high-power headlamp?
It's been itching me to try my hand at one, but I don't have much experience with electronics other than reading some stuff from the general and hooking up little LEDs. What I have in mind is a to make a caving headlamp that is relatively cheap, waterproof and with more than one lighting mode and/or a dimmer. From what I figured, Scurions are much too expensive for what they are, and it's not impossible to make one yourself.
I thought I'd ask around here since I have no idea what I'm doing or where to start.

Why not literally duct tape some of those $1 ebay led torches onto any helmet, they are really bright and they are waterproof
>>1022119
You need to adapt the light and its spread in caves. Plus by wiring them all together in order to turn them on all at once they stop being waterproof
>>1022131
they can zoom in and out, and you dont have to wire them, they come with buttons and is waterproof, why do you need one button rather than three, more buttons is even more adaptable
Hey newb trying to setup linux, tor and tails on to flash memory... suggestions?
Install gentoo
Beauty thx
Visit Linux forums. 4chan is not a computer forum. Why anyone would poast computer questions here is a mystery, and OPs answers are ALL easily found via Google.
I don't ask a gas station attendant for medical advice either.
Google "tails usb installer" then GTFO since this isn't /spoonfeed/

I am ending my own arcade machine, but I have a little problem of how to fix the command control. I was thinking to avoid buying the small controller (photo) and make one for myself and figure out how to connect / solder a keyboard or joystick under control, where the lever and buttons are.

>what is the best way to ask a retarded question?
>>1021821
For best results use an FPGA. If you have no idea what an FPGA is, don't use an FPGA.
So computers today have fuckloads of processing power, even a goddamn raspberry pi ought to be able to emulate damn near any old arcade machine.
For your controller, the first thing I think of would be to use an arduino to make a USB human input device to convert button presses into something the computer can use.
how much you reckon i would have to pay someone to weld this for me
if i provided and cut the steel and drilled the two holes myself
how much do you think they would charge if they cut the steel and did the measurements themselves?
front bumper bike rack? that is dangerous and illegal.

Dude why don't you just throw it in the fucking trunk, why the hell would you even think about putting something on the front of a pickup, jesus christ.
Real quick, does anyone know how to make a filter or mask for sleep gas? A friends house got gassed a while ago by robbers, and they took all his shit.
I have cams and replaced my doors/locks with tougher ones.
Pic unrelated. Halp pls?
uh...
Without knowing what they used, your best bet is going to be a refurbed milsurp mask. New filter cans and everything.

How do I make a simple as fuck website? I know nearly nothing about CSS/HTML, should I just use one of these services like weebly, or is there a decent tutorial somewhere about website building that I can't seem to find?
>>1020967
CSS/HTML are scripting languages. You either learn them or you don't use them. You can't pop in, learn three lines, and the call it good. You have to actually know what you are doing for something to look decent. If WYSIWYG is what you want, use that.

I want to connect these two because I'm too lazy to buy a transformer.
Is it possible?
What are the other ends connected to?
>Inb4 guitar and headphones
>>1020964
amp and headphones
kek
>>1020961
>i'm too lazy to buy a transformer.
A transformer has nothing to do with this.
Connect the tip of the 1/4 to the tip and the ring of the 3.5mm. Tip is left speaker, ring is right speaker.
Your guitar amp is mono, if you only connect one only one side of your headphones will work.
Then connect the sleeves of both together, which is just ground.
Do note that if you are trying to use a Line Out plug, you wont get much volume out of it.
I want to rerun my supply line. Anybody have experience with PEX pipe?
Yes, I have.
>>1020913
No, I have never used PEX pipe.
>>1020913
No, i knly do plumbing repairs eveey so often for friends and family, and i havent cone across pex yet, usually pvc or copper. but it seems solid and a little easier than pvc. I think you have to buy a tool for the crimps(I don't imagine a basic one being more than $20), but you'll probably make your money back compared to the solvent and primer you'd have to buy and the fittings you'd need every 10 ft with pvc.
Hello /diy/
I have a throttle body that I want to disassembly because of reasons. Of course I want as less damage as possible.
Unfortunately all the levers seem to be brazed or welded to the both shafts.
Has anybody an idea how I can get the levers of the shafts without totally destroying the parts? Is there a good way to test if the parts are welded or brazed?
>>1020751
I don't know, they don't look welded to me. Clean it up. If you can't figure out how it's fixed on, try dremel'ing it loose, then re-weld it. It'll work just fine if you do it right.
i have taken apart any electronic throttle bodies
are you trying to rebuild it or harvest it for parts?
Hey /diy/ first-time poster here.
I've been looking at some of the stuff you guys tend to do and it looks this board really knows their shit.
I've recently purchased an airgun target box and want to be able to practice indoors because the laws are retarded.
However I'd like something I can move and that doesn't cost too much.
I have two left hands but want to try to make something anyway.
I'm not yet at the point where I'm certain I'm not gonna shoot outside the box.
Any ideas for something that could be made/converted into something that I can move and that can withstand high speed low drag airgun pelets ?
I was thinking of something like a clothes rack on wheels and attempt to put something strong metal plate or wood on it, on which I'd screw in the target box.
Any ideas ? I know you guys can be quite creative and I'd like some inputt here.
Hi, gun enthusiast here. I have a few traps I made for my kids.
Just so it's perfectly clear, are you going to be shooting a pellet rifle or BB gun?
Also, why does the target/trap need to be moved with such a heavy frame? All the ones I have are exceptionally light, and a commercial BB trap I have is literally a foam block with plastic wrap on the outside, with a handle on top. It weighs ounces, not pounds.
>>1020617
>it looks this board really knows their shit
I must have missed those threads.
What kind of pellet are we talking about here? An Airforce Condor is gonna require something different than a little co2 pistol will. A better description of your target box would help too. And are you wanting a pellet trap or just a backstop to take care of the fliers?
It really doesn't take much to stop pellets, and there's loads of designs for pellet stopping contraptions. Something like the rack in your pic with a few layers of carpet hanging off it will stop them surprisingly well. But it would really help to know what exactly you're looking to build and what exactly it's going to have to withstand.
I'm seriously looking at getting a small milling machine for my tiny shop outside.
I've been looking around the Web and I get a lot of conflicting advice or the usual pompous "buy a $20k Bridgeport or you'll never be able to mill anything."
One thing I do keep seeing is people upgrading the sieg mills, like the harbor freight ones at the link below
http://m.harborfreight.com/two-speed-variable-bench-mill-drill-machine-44991.html
Does anyone have any experience with them? Any other suggestions for a decent mini mill? I'm just looking for something to make one off parts and do small projects.
>>1020520
They are crap. Our machine shop bought one and it took the greasy rags in the shop weeks to get it dialed in. They had to make some of their own parts on the old lathe to replace the crap it was made out of. They are sloppy and inaccurate. Lots of aluminum in them. It flexes. And none of the indicators on it were accurate even after being set. They do work and for the price they can't be beat but you get what you pay for.
Buy a used, decent one and skip the Chinese junk.
>>1020411
I only have a small outdoor shed to work in so anything huge is out of the question.
Have any recommendations on a decently small mill that can actually do something useful?
>>1020520
sherline? what exactly are you planning on using a mill for?
Brother told me my cable joints were unsafe and gave me these.
>>1019696
Yeah they are safe to use, otherwise it wouldnt be a fucking thing you can buy in a shop would it
>>1019699
True but I'm not sure how much they can handle and how they handle long term. Had a thread recently, most people there said one should only solder or cold solder or else oxidation and heat will build up and create a fire.
>>1019704
These can handle household mains wires
hi /diy/, i get an old handheld blowtorch used for brazin a/c pipes, but is quite old and dysfunctional. principally cos the gas mixer was too oxidized etc...
the thing is, im planning to make a new mixer with a piece of cupronickel. but there are several of differents flameshapes i guess for difents uses like cooking, brazing, or just heating. and i dont know whats the best for melting things a large one or someone like the pic.
anyway why no blowtorch tread?
>>1019640
that's the experimentation subjet
>>1019641
that's the mixer. the center hole its outsized and the others dwarfed cos oxide
You could check out lp/air torch heads like the classic turbotorch for inspiration. They are plentiful on Ebay but torches are interesting to play with. I rebuild torches to use and as a hobby.
Sup /diy/ I swear to god this isn't /o/ related
I'm buying a Lexus SC400/LS400 because I need the engine for a project.
>dat 1uzfe
I can then part out and scrap the rest of the car, or..
The chances are good that I will end up with a LS400 with a nice interior, or a SC400 2 door with an okay interior.
What if I took that shell, kept the nice interior, put it all up on a motion platform with a projection screen and wired up the controls?
I searched for motion platform threads already. The hydraulics and controllers are coming down in price, it looks like. I used to dream of having a cockpit only motion sim, and now I think this is really doable.
what think you?
>>1019416
I want to say "you are in so far over your head that you don't even know enough to know how far in over your head you are". But this isn't necessarily an entirely unrealistic project.
The most glaring issue is the odds that you don't actually have a place to put this. Throwing a car around takes a LOT of force, even if you strip it down to the body, frame, and interior. You can't just bolt this thing to some shitty 6" slab of concrete and expect it to hold up. If you DO have a solid foundation to stick this to, it's not a concern, but if you don't, you're either going to be shelling out to have one poured, or busting your ass for god knows how long doing the bulk of the work yourself.
You're also going to need the help of someone with machine and metal fabrication tools, as it's unlikely you're going to find off-the-shelf parts to make all of this work.
And, of course, there's the problem of actually interfacing the mechanics to the electronics. Even if you're able to find something ready-made that can pull useful physics data out of the game engine(s) you're wanting to play in, you're still going to need some way of converting that data into signals for the hydraulic controls to use. With as many variables involved as there are, I'd be willing to bet there's no way you're going to find suitable hardware to do that. At bare minimum, you're going to need to enlist the help of an electronics guy, if not outright learn how make what you need yourself.
You're looking at a long, difficult, expensive project no matter what. $5 says you never finish it, if you even get started.
>>1019421
>$5 says you never finish it, if you even get started.
Sounds like 90% of the pipe dreams on this board.
