power

I've been trying to search through the threads for a while now and these are the 2 questions I keep coming back to. What way should I wire up the charger and batteries to do a charge n play setup at 7.4v? Do I have to wire the original wii power button or use a switch directly at the source (...

Ok, so here is a project that I have been working on to help out with building my portables. Not a portable itself but I wanted to get you guys opinion on how I should finish it up. I took an old useless desktop and stripped all the parts out and figured I would use the power supply as a bench...

I am referring to the circuit inside of the portable and how can you add a battery life indicator to tell if the battery is charged or dead? SOLVED:
