I wanted to build a custom rugged battery box on a budget for amateur radio communications and emergency charging. The ammo can was found in poor condition at an army surplus and was restored by sanding to remove rust, re-painting, and lubricating the rubber seal. I’m not yet satisfied with the internal fabrication and will continue to improve upon its design later. Future improvements to include: led switch, solar charge controller, improved mounting panel, volt/amp meter.

Many of us tried the old “Two tin cans connected by a string” experiment as kids. [Michael Rainey, AA1TJ] never quite forgot it. Back in 2009, he built “El Silbo”, a ham radio transmitter powered entirely by his voice. El Silbo is a Double Side Band (DSB) transmitter for 75 meters.
