As promised, here is the prototype remote detonator/activator. Factory specs say it can transmit/recive up to 500 meters (1,641 feet). This is a protptype so it is much larger than the final product can be. I say can be because this model can control up to 6 different devices (although I only have it wired for 1) Right now this is set to produce 18v out of the two terminals, so that it can activate an electronic valve for an air cannon.
