Using the ac adapter from an old parallel port external Zip drive and a USB to PS2 mouse adapter, I made this Ipod charger.
Step 1: parts and tools
I used the AC/DC power adapter plug (5.0V DC output) from an old parallel port zip drive, and the ps2 adapter that came with my USB optical mouse. Two things I'll surely never use again.
The tools I used were a sharp knife, an electric multimeter, soldering iron and solder, a pair of diagonal wire cutters, and some wire strippers.
