/diy/ - Do-It-Yourself

Going to try and learn carpentry as a past time with my father who has more experience in it than I, and I'm wondering what would be a good beginner project? Weather's about to break so I can't wait to get into it and learn.

I don't know how to ask this, but it seems that every open source hardware project is easily beaten by older proprietary hardware that is hackable. It's way cheaper, and it does better in everything except maybe form factor and power usage, and that's only occasionally (linux still does worse in power management for my x86 hardware). Hackable hardware is like my vape which can flash custom firmware (arcticfox firmware for joyetech devices). I bought a tmobile 1900 to flash to AC68U because it was hackable.

rPi is cool for $35 but you can do much better emulating on a cheap netbook. All the nerdy stuff can be configuration with a good router anyway (merlin/tomato compatibility). The more open eink devices are easily beaten by flashing an old kindle. Every arduino project is stupid and I still haven't seen any use for them aside from LED controllers.

Is the best for DIY electronics simply cracking hardware or getting corporate sponsorship? I have flashlights with custom firmware too which seems to be working with corporations to create cool stuff (shameless plug for FW3A, a cheap flashlight with good fw). My question is sorta how you feel about this and what's your method? To find the stuff with the best specs that you can unlock, or find hardware that is open source that you can contribute to? The best ones seem to be from corporations, got any "hackable" electronics you care to share?

Ok, now that we've got that out of the way, I replaced the valve on my 50 year old LPG (Propane) furnace in my house trailer, made a manometer to set the inlet and outlet pressure, but no matter how far I diverged from the specified values, the flame was mostly yellow. So I set them to the correct values and just worried.

And then I noticed that the moment I opened the porthole door, the flame seemed to be a bit more blue for a moment, so I covered it with plexiglas and the flame was nearly completely blue. It's a simple furnace that draws air down a passageway around the exhaust pipe without any sort of forced air, so how would opening the door to look in cause the oxygen level to drop so much? If anything, I would expect it to be the other way around.

Hey /diy/, the 2019 Spring Babby Cup is around one month away, a competition which this board can be able to participate, and I've been wondering if you want the board to be in.
>What is this?
The 4CC is a site wide project where boards come together to face off in games of AI vs. AI virtual soccer/football. There are elite cups which are held in Summer and Winter and babby cups which are held in Spring and Autumn. More info can be found at https://implyingrigged.info/wiki/FAQ
>Did this board ever participate?
Yes, back in 2015. An archive of /diy/'s run back then can be found here http://archive.klaxa.eu/Autumn_2015/
If you are wondering here's the old roster back when the team was alive https://implyingrigged.info/wiki//diy/
>What is this thread for?
It's in order to see if the board wants to participate and update the 4 year old roster if you want in.
You can simply reply yes, no or fuck off.
>I'm interested in helping the team. What do I need to do?
You can contact the commissioner and he will inform you with what you could help. https://implyingrigged.info/wiki/Contact#Commissioner
>Do you guys actually like this autistic shit?
Yes.

Hello /diy/ its the first tim im here. I was looking for a way to make a video synthesizer with arduino or something else, some options are great but i feel like im going to get stuck easly and im going hate it more than i thought. Is there any easy -noob level- video synth to build?

What are my options here?

What would you choose & why?

Heard plumbers can go solo and make decent money but that more often carpenters can go to supervisors on construction sites more often.

Quick question, not sure if this is the right place for it.
I'm making a shitty puppet thing and the head is giving me trouble. At first it was connected to two points- one to the body at the bottom, and one to a wire connected to my thumb at the top. But it just flopped around no matter what I did.
Then I connected another wire to my thumb and the anchor point where it connects to the body. That helped a little, but it still flops around a lot and I can't get near the control I want.
Does anyone know how I should set it up where I can make it move controllably on all three axes?

I've got a QRX9001 quad amp that was left to rot in a garage for an untold number of years. It's been on my todo shelf for a while and I'd like to get to it this summer. When I had first gotten it I, probably foolishly, tried to plug it in and turn it on. It was initially set to 220V, I didn't see that and plugged it into 120V briefly before changing the setting. I don't know if that would have caused horrendous damage but hopefully not. If I recall, once I had it configured correctly the face lights came on and there was some quiet crackling noise through the headphone jack and maybe in the speakers. I've got myself a function generator+oscilloscope, multimeter, soldering iron, lab power supply, and little experience with this sort of work. How should I get started debugging this thing?

I'm building a vape, how safe is it to inhale air heated by a soldering iron heating element?

Can you recommend a practical book on mechatronics?

I‘m a CompSci student and purely out of interest I want to get into being able to build my own electrical devices. Yes, that‘s vague but my ideas could take me in all kinds of directions. I need something that gives me an understanding in engineering in general. For example, right now I‘m interested in drones, so it would be great to buid my own. Not finished drones to buy from Amazon, I want to build it myself. Maybe with a 3D printer and individual electric components that I assembe myself.

Give a newbie a nodge in the right direction. Thanks

Still toying with the idea for this project, so hopefully you guys can give me some input as to how feasible this will be.

> an stand-alone installation that will incorporate a series of tiny displays
> all of which display a part of a generated maze (which will update every 5 mins or so).

What I'm looking to know is, mainly on the hardware side:

> is this possible on some sort of arduino/raspberry based system?
> what would be the upper limit of displays that I can attach? How far can I expand the upper limit, and if at all?

If the arduino idea is wack, hopefully someone can suggest some alternative methods for executing this. Suggestions on where to get simple display panels in bulk so that it's still cost effective are also appreciated, but I'm most interested in figuring out the hardware that this system should be running on.

Hi /diy/
I'm thinking about creating a van to sleep in to escape my family. I already live frugally, and I only use the bathroom once a week, so it shouldn't be too hard on me. I only need access to a computer and wifi, and I have a gym membership, so showers I have access to.

How should I go about doing this? I have $9,000 I can use before I go broke. Hopefully I can only use half of it, and then use the other for food. Has anyone done this before? I'm planning on removing the back seat, adding a wood base, and covering the windows up.

Just started welding a few weeks ago, using gasless mig, only welding uncoated steel.

2 days got sudden flu symptoms, so I'm thinking it was metal fume fever, but I never welded or grinded galvanized steel.

So what do you guys think, can you get sick from grinding/welding without a respirator?

Hi, I'm hereby starting this thread to act as a baking club, where you can post pictures of your sweet creations.

Wood is bad enough, but glued together wood chips?
Why do these shacks cost so god damn much that you need 20 year mortgages to pay for them?
Will the house even last that long?
American home construction is just one giant scam.

Hello, /diy/. First time posting here. Im 22 yo full time college student. I spend most of my day studying, which makes me feel bored sometimes. Also, I'm extremely good at doing/building/fixing stuff with my hands, it just feels so natural and easy to me. My question is what are some DIY projects I could fill my free time with and possibly make a dinner money off? The only good idea I have is to make a custom sub boxes. Tools are not a problem, my father works on construction and we have all sorts of them in the garage.
Thank you.
