Now, I could see you being offended by the ternm n00b. That's a whole other ball game. After reading your post, you're certainly not a n00b, just a newbie.
Uhhhh. Nobody uses a 500mah DC power supply to power an M2ATX in the house. Why? The M2ATX will draw far more than half an amp.Ok so I got a really good start and have supposedly well rounded system components but how do i power it in my house to set it up. So alot of people use 12v 500mah powersupply but I still want to power up otherstuff that my computer *carputer may use, and I really don't want to spend anymore money.
Yay! A revealing.My atx supply has multiple voltages and also has protection circuitry, so really why wouldn't I use it. Most people don't know how to search the net for Ideas but I do. And so the point of my blog is revieled!
Actually, I'm gonn stop here. I see what you're doing and believe I understand what you want out of this little project.
There's a far easier method to achieve what you want. I outlined it in a FAQ here: http://www.mp3car.com/wiki/index.php...on_a_workbench
Those are legitimate concerns. I can assure you that what I outlined doesn't involve soldering (unless you really feel like it), doesn't screw up the ATX power supply and uses more common components that are likely to be cheaper. Hell, most hardcore computer geeks would have the stuff lying around.How to do it without f-ing up my supply! not really that tough though you must be able to solder and apply common sense to electircal components. Controlled canibalization is ok if you have components lying arround that you will never use.
