Hey /diy/,
Need help, moved into a new flat and the radiator isn't connected, it's pretty cold today and I have no idea how to connect this thing up as I have almost no electrical knowledge.

Pic related, it's the cables.
Thanks ahead for helping a bro out.

No ground wire? This is not how this is supposed to work OP. Just buy a power plug from the hardware store and wire it up properly rather than trying to twist mains voltage wires together.
>>
OP Here, thanks for the replay, as I said I have no idea, these wires are the ones that are both behind the radiator and no plug sockets are around, so I figured they were to be connected up this way. :/

Hey guys
I don't know if you're familiar with the world of music so I'm gonna make it simple. I bought a new mic for my strat and need to make the bottom cavity larger in order for it to fit in. I don't own a router and asking a profesional to do it would be commiting economic suicide for me.
So I was wondering how risky it would be to chisel the hole considering the fact that the wood is varnished
I hope you can help me DIY guys !

Don't have to know much about music to know that you are retarded for wanting to put a mic on a solid body instrument.

Why don't you just install a new pickup OP?

>>951721
That's what I meant by mic (the humbucker in the pic is the pickup we're talking about)

>>951719
Seems like a bad idea even if you had a router. If you dont care about the guitar just go for it and never look back. Worst case it'll sound and look like shit and you'll have to fix it more.

This is a dumb question. Connect one op-amp as usual, connect both inputs on the other op-amp to GND.

Leave the unneeded opamp unconnected.
Or better, connect its OUT to IN(-) and IN(+) to ground.

I need help figuring out if there's a toxin in my room and what it is. The house is old as fuck so it could be anything but I know pretty much everything has been repainted, there's water damage though pretty bad, the insulation and walls have all been replaced in the past 10 years.

It's probably in your head. Since you mentioned water damage I'll say mold though. There's tests someone can do to find out what's in the room. That's pretty much the only way to know for sure.

New to electronics. Anybody have any idea why I can't fix this fish tank lid? It has two fluorescent bulbs.

I've replaced;
- The bulbs themselves
- The lamp starter switches.
- The ballast.

.. and it still won't work.

If I touch the lamps to power, then they flicker so I know there's power. As soon as I put them in the fittings properly they switch off. Which part is going wrong here?

Sorry for bad quality photo/diagram.

Being in a fish tank lid I'd suspect corroded sockets.

>>951687
Nope. Sockets are fine. I've used a voltmeter on the last starter switch in the circuit & get a reading, so presumably (unless I'm wrong) that means that at least the first bulb should be lit up?

I've only changed out 3 ballasts before and I could have sworn that the lamps were parralel with ballast? Not sure if that would matter

You can buy metal scrap at home depot. Pic related looks like a few pieces of 1 1/2in Angle iron, and some flat bar for supports. Weld the pieces together, then drill holes and attach the wood. Fairly straightforward.
>>
>>950940
their metal prices are too high. scrap prices are in the lows right now, you could buy a truckload at your local scrap dealer for 10 bucks probably. straight stuff too.

Use wood planks and metal bars.

Do you know how to weld?

Does anyone here study or work in product design? I asked on /sci/ but they were all cold, hard engineering and /g/ only seems to do EE or CS so maybe it's a /diy/ kind of degree. I got interested because I found out that all my attempts at designing a product to sell is an actual career field called surprise, surprise product design. I could do engineering but product design seems a) more fun and b) more geared towards self employment plus it's available at my local university whereas engineering isn't. However engineering seems to have more jobs and pay more. Thoughts?

Could I get some advice/input/ideas on converting this wine fridge into a chicken egg incubator?
What do you think is the easiest way to go about doing it?

The power cord on the one I have is cut off, I have to attach a new one, other than that, I am pretty sure the thermostat works, but the cooling element is busted, according to what the people said.

Thanks in advance.

What I have so far that I can use:
Several broken headphones
one multiturn potentiometer
a cable HDMI (which has 16 wires inside)

The character I'm writing basically got his techno-terrorist start of darkness by completely shutting down his shitty college apartment's computer lab.

OSX is basically a UNIX variant, and obviously there are different ways to manhandle one. Deleting /lib or /bin (if there is root access) would probably fuck up the system. Permanently bricking? That's another question.

High voltage surge over any components. I remember macs have a shitty chip that prevents them from overheating by slowing down procesor speed to a crawl. And this chip can be overheated with a few simple comands. Once it overheats the os wont boot.

50 miles? Look at Sprint or AT&T phones with a PTT (Push To Talk) function.

Handhelds aren't going to get you a 50 mile range without base stations and/or repeaters. So use the cellular network.

I've built LED goggles myself, and its a lot easier to see through them than you'd think. You need to prevent light from shining in your eyes by painting the backs of the LEDs or use something like the 5050s that already have a backing. After that it's no different than seeing through those venetian blind shades. Your brain just filters out obstructions close to your eyeballs.

He might not. He might look down or have mirrors that look down. They might have directions and shit on the stage for them to follow and all he needs to do most of the time is stand at his keyboard or whatever. Even easier when it's not a live show.
