Yeah but for what? It doesn't have a handle that spins so I don't think it is for some old tractor or anything like that, maybe for part of a well?

Okay /DIY/. I am making a microcontroller dev board, but it is super compact and you can get fabricated if you like it. (As in the Gerber files and such will be posted online after extensive testing)

I am just having one problem after copious amounts of googling. This connector in this picture. For the love of God what is it called? It will be used for board interconnects but if I can't figure it out I might as well just use an arduino or some clone of it.

Anyways any help is appreciated.

Hello there I was managing my cables as I did some few changes on my setup,
Just wanted you guys to give me if possible some advice with it, as it is a transparent cristal desk and it can't be drilled. Double side tapes are an option, but it would be weird as the desk is transparent. What do you say?
Also feel free to post your own works im sure your proud with.

Your cables are too short to really do much with it. Everything is pulled tight, no slack for routing.

I would just go with a nice paintable cable raceway down the wall, personally.

your cables are too short to go to the right

if you can maybe try to stick some cable tie mounts on the under side of the desk and then run everything to the right side of the desk and then drop from there, under the desk, so it will be totally invisible

Hey electronics people.

How would you rig up your houses electriity box to tell you which outlet, specifically, is having electricity drained from it?

I got the idea because at one point in my life, my family had two homes. We had electricity in them both, but only lived in one because of reasons. No, it's not because we're rich, it was because of a divorce, and then we needed to go to a better school. etc.

anyway. We had neighbors sneak over while we weren't occupying the house and rig up extension cords so they could sap our electricity....

I'd install cameras.

>>935428
Because the house was unoccupied, everything was unplugged, but my mother kept the power on because we visited occasionally to clean it up. When your electricity bill goes up to $50 a month despite using absolutely no power for lights, heat or flushing the toilet, there's only a few things it could be.

Hey guys I have a sickness and the only cure is more anvils ringing. Post pics of current projects you may be working on, favorite tools, techniques you just learned, inspire others to make something great. That being said, I'm currently a newbie and I'm thinking way ahead, I'm really not sure what anvil to get. Refflinghaus, peddinghaus-ridgid, Turkish/Czech anvils, cast steel Nimba, or the relatively new cast steel Blu anvils.

I'll try to keep this one alive so I can actually get some content going. To answer your first obvious question, yes I do realise I sound like an autist that has no idea what they're doing.

>>935248
Each of the extractor fans is supposedly rated to push (up to) 445cfm through a 100mm x 3m duct (which I guess is probably marketing BS then).

Problem is I don't know how much cfm I need (no documentation), and even if I did I don't have an anemometer to measure it.

The two extractors together push enough air to provide a slight positive pressure at the intake while the unit is running so I figure it's about right.

The purpose of the cooling system is to keep the room cool, the computer will be getting it's own extraction hose in a little bit, but it only spits out about 500w of heat under heavy load. The main problem is that the outside temperature gets above 45C here sometimes which renders the room uninhabitable.

I'm going to make some more tweaks to it and see how much I can get out of it. Cooling capacity on this unit is supposedly 2.6kW which should be more than enough, but in its stock configuration, even running continuously it didn't cool the room more than about 5 degrees ( tested at 35C down to 30C, 38C down to 34C).

With this intake system it cools more like 10C, (36C down to 26-27C).

My goal is to be able to get down to 24C in 40C weather.

Next step is sealing any leaks, adding my custom scoop and insulating the exhaust hose.

I'm considering diverting some of the air from the intake system to the cold side radiator, theory being that I could push the room into a slightly positive pressure, preventing hot air from being drawn from the outside.

Last resort is mounting the whole unit up on the windowsill inside a box.

If that doesn't work I'll bite the bullet and buy a window A/C unit.

1. make sure the condenser is clean, and the evaporator for that matter.
2. switch to metal ducting, it flows more air with less friction. Tape all the joints with foil tape, not duct tape.
3.insulate your ductwork, because youre bringing unconditioned air into your living space, and heat is transferring through your duct material into the room air.
4. room size? LxWxH
5 A/C btu rating?
6. just get the window a/c.

2. I don't really want to buy more tubing, but I'll try using foil tape in you think it will help. Do you think it would be helpful to make some kind of joining piece to connect the two 100mm hoses to the 150mm hose?

3. What should I use to insulate it? Fibreglass? Foam? Preferably something cheap I can pick up at the hardware store.

1. if its clean, then its clean.
2. foil tape wont make a difference with your current ducts. and making a plenum box wont help with flow on your current setup, just make sure its sealed where the three hoses join.
3. duct wrap or something similar pic related, fiberglass inside aluminium outside.

your op pic looks like you have black paper taped over a window wall, could you hang a heavy curtain as an insulator? or add an awning to keep sun off the windows? keep as much heat out as possible. if you need...

I''ve been toying with the idea, and i think it could be done at a reasonable price, but I thought i would ask here if anyone had some experience? what parts should be bought as specific 3d printer parts, and which could be replaced with standart "home depo" stuff without much trouble? and what kind of software should be used?

If you can scrounge up your own frames and motors, then you'd really only need to buy the printer head and main board.

Frame could def. be wood or something, but you need nice stepper motors, which you could salvage from printers or something. In the link he's using dvd drives.

Belt driven axis' are easy as shit to build with linear extrusion and home depot parts. I bought 28 shower door rollers for the openbuilds stuff, they fit beautifully, and don't cost 4-5$ a piece like they want for wheels.

I got one of these bt recievers to 3.5 for my 1980s car with cassette.
It has a small battery that lasts 4 hours and charges in 1.5.
How improbable would it be, that if I hardwired this to a 5v point on my car so it charges 24/7 it wouldn't drain my battery if I drive daily?
On another note I could add a powerbank to it and have the car charge that when powered on.
Another thing I thought of was removing the battery and simply have it power on when I turn on the radio soldering where the battery would be to some 5v point on the radio (probably the backlight...

Pretty trivial except your car is almost certainly 12v. So then you just need a Usb car charger and plug that into your cigarette lighter.

Or get this you just plug in a 2 sided 3.5 jack from phone to cassette player. Skip the middleman. No batteries of moving parts. Its the technological revolution apple doesn't want you to know about.
Bluetooth is a technology ahead of it's time. It may be viable when we get decent super capacitor batteries, but for know it's just a shiny thingy too slow to be useful but to cool for school.

It's mjust a pain to take my phone out of my pocket and connect the 3.5 jack every time I want music.
Right now I soldered the BT chip to my radio so it actually works, the only problem is battery and turning it on every time.

Assorted small files, moulds, a small furnace capable of melting metal, a few crucibles, dremel, etc.

It really depends on how you want to do it and what materials you wish to use. I've made rings with wood, brass, steel, etc and every one of them required a slightly different method.

Google is your friend, there are very, very many tutorials on ring making. Go watch some youtube videos.

Hi /diy/, wasn't sure what board I should post this on so forgive me if it's not allowed. I bought what appears to be a handmade samurai lamp at a swap meet for 5$ from some old lady who literally had this and like 2 other things on her table. Never seen anything like it until now, thought it was too cool to pass up. can anyone tell me about it or if it's worth anything? Looks extremely old. It's also fully functional and about 2 feet tall.

So I own a sony xperias z3 dual, I think they're the best phones around for the money except for one HUGE thing; they have glass back panels that crack easily.

I've had the back replaced twice now and I'm over the glass so I'm wondering if it's possible to recreate a back panel with thin metal using a cad design.

I have two questions.
1. Can this work or is it a stupid idea
2. How can I get the cad design? Will metal laser cutters be able to trace an aftermarket replica of the back perfectly or will I need to beg sony for a design?

Cheers...
