A new split rail for the STEM kids

Get 5 boards in about a week for $22! In this video I iterate the split rail power supply using the ICL7660 8 Pin IC board from April of this year. I had a capacitor flipped, kinda the way it goes when it’s just one guy. Anyway this board is now 90% working, but I am still losing about a volt on the negative side. ************************************************************************* *Please help support this channel at NO COST TO YOU.
