Lab Overview This circuit uses the output from a modified digital kitchen timer to trigger a SCR (Q1) to fire a single detonator. Tools / Parts / Test Equipment Soldering Iron Helping Hands Solder Multimeter SCR Kitchen Timer Kit

Lab Overview This circuit uses the output from a modified digital kitchen timer and a normally open switch to arm and fire the circuit, respectively. Tools / Parts / Test Equipment Soldering Iron Helping Hands Solder Multimeter

Lab Overview This is a classic EOD problem where if one detonator is cut the other detonator fires. Tools / Parts / Test Equipment Soldering Iron Helping Hands Solder Multimeter

Lab Overview This device utilizes 4 SCRs to operate as a Two OR Configuration for arming and a Two Or Configuration for firing. Tools / Parts / Test Equipment Soldering Iron Helping Hands Solder Multimeter

Lab Overview This is identical to the Single Wire Command Det except it has been modified to ease assembly and deployment for training. A screw terminal is provided for the earth ground spike and the camera flashes high input, instead of soldering directly to the board. Tools / Parts / Test Equipment Soldering Iron Helping […]

Lab Overview This is a command wire circuit that uses a modified camera flash to send a high voltage output to a NPN transistor to trigger the gate of an SCR energizing the control circuit of a relay. Tools / Parts / Test Equipment Soldering Iron Helping Hands Solder Multimeter

Lab Overview This circuit is based on the predecessor to the RFT-2 with some modifications.The firing circuit has been replaced with an SCR and the CWC-7 is replaced with a radio module and a PT-2272 decoder IC. Tools / Parts / Test Equipment Soldering Iron Helping Hands Solder Multimeter

Lab Overview This radio circuit, historically recognized as RFT-2, utilizes a QUAD NOR Gate and RC timer to accomplish an arm timer. Upon completion of the timer, power is provided to the radio module (Historically a ‘CWC-7’), and the circuit waits for a signal from the module. This fires a single detonator through a Darlington […]

Lab Overview This circuit uses a LDR and a SCR to fire the device when a cell phone screen lights up or a victim opens the package. Tools / Parts / Test Equipment Soldering Iron Helping Hands Solder Multimeter

Lab Overview SCR 1 and 2 are in parallel, SCR 3 and 4 are parallel, but SCR 1 and 2 are in series with SCR 3 and 4. This makes the circuit a Two OR Configuration for arming and a Two Or Configuration for firing. If either of the arming SCR’s (SCR 3 and SCR […]

Lab Overview 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 an SCR. When B2 is removed, the circuit collapses and fires a Detonator. Tools / Parts / Test Equipment Soldering Iron Helping Hands Solder Multimeter
