URDU Transistor Battery Disconnect

Please sign up for the course before starting the lesson.

Lab OverviewThis 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.Tools / Parts / Test EquipmentSoldering IronHelping Hands Solder Multimeter
