Hey EZB-ers! I came across this site when trying to figure out an ample power supply for my EZB project. PC to DC Power Supply! The link at the top brings you to another page with more detail on the process.
It gives basic instructions on how to convert an old PC power supply and use the 5v, 12v, or 3.3v lines.
A PC power supply will give plenty of amps when running multiple servos.
I figured I would share. Good Luck!
