5V Regulator Cap for 9V battery

David Cook built a 5V regulator to sit atop a 9V battery: For quick portable projects and temporary hacks, it is often faster to reuse a simple 5V regulator circuit than to integrate a power supply into the device design. My toolbox has an LED tester and magnifier light, so why not...
