Now, for the good stuff.
I've recently been trying to build a gamecube into my computer using a PVR and an RF adapter (Windows Media Center doesn't like switching between inputs). Worked great, but then had to put the GC's little fan back on beacause it was overheating, unfortunately. Got that working, not a problem. Then I got a new computer case, so the cooling problem might be gone (Antec 900, lots of fans, chilly).
Now, before, I was using the original power block, velcroed to the back of the computer. It was really ugly. Then, I took a look at the power output of said brick. Huzzah! 12v output, 3.5 amps. Now, I know my computers PSU can handle that, outputting 20A on each rail. So, I went out and bought an extra GC power adapter (because I know I will break one, always) and cut off the cord at the end. Crap. another obstacle, the end is nearly impossible to get into, meaning I need to pull out my multimeter to figure out which one is ground and which one is 12v. What do you know, Multimeter went missing. Found it. If it isn't one thing, then it's another, multimeter stopped working. But I figure it's just a dead battery, nothing too bad (it was a MM I got free in a science kit when I was 11, what do you expect). Anyway, I would like for some handy gentleman or gentlelady to check which is which, please. Once I'm done, I'll post pictures of the final product.
Also, post any suggestions you may have, or questions. After reading through the posts Electric Rain has made, I see he is pretty smart, and I don't really want to plug anything into anything without him saying I won't end up with a fire in my computer.
