Tetranitrate writes – “This project describes how to build a simple, safe, and reliable electronic detonator. All the parts should total under 25$, and all but one of the parts can be bought at radio shack. This detonator includes numerous safety features such as a detachable power supply, an ARM switch, and an indicator light.” – Link.
