The 5V Pocket Rechargeable Power Supply: Dave Prochnow
Sure power supply projects aren't that sexy; but they are, generally speaking, the foundation for every electronics project. The voltage output for this project is 5VDC, and a practical output that can be applied to a wide variety of digital components.
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.
