Description

Almost complete. MSP430 mini power supply. Takes DC in up to ~12V, outputs 0-~11V. Displays current usage, and when complete, software will allow for current limiting as well. Circuits works, possibly needs some tweaks for increased accuracy (virtual ground, try to limit digital noise?). Very handy and in a small package!
