Who needs a very small 5 volt power supply for their project that is capable of 4.2 Amps? I have at least 15 available. These are Condor brand and measure 4.25" by 2.5". These are bare board supplies so it will need mounting-perfect for a microl projector! I am asking $20 including shipping to the USA. Phil, 142laser (813) 974-2378 or pbergero@usf<dot>edu
