Open Ground Penetrating Radar
Details from Open Ground Penetrating Radar
A Baofeng VHF/UHF radio is used a signal generator, which transmits via a Transmit/Recieve switch through an antenna. A RF detector is also connected to the T/R switch, which is connected to the MSO-19.The radio controller is a 4N25 opto-isolator.The...

Circuits needed
Log from Hedgehog Spotter
Ok, so we need the following:PIR circuit: that's just send 5v, and returns high/low to inputLight sensor: that's just send 5v, and returns high/low to inputIR illumination: we switch this by sending high/low from an output. Since it is 12v, and the Pi...
