77- URDU Transistor Battery Disconnect
$21.50 – $71.50
This circuit functions the same as the typical collapsing circuit that would use two batteries and a relay, except here, we replace the relay with a capacitor and an NPN Transistor (Q2, C1). When B2 is removed, the circuit collapses and fires a detonator.
