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 Downloads Related Circuits in the Library Circuit #12 — Kitchen Timer SCR

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 Related Circuits in the Library Circuit #39 — Dual SCR

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 Related Circuits in the Library Circuit #42 — Balanced SCR

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 Downloads Related Circuits in the Library Circuit #18 — Quad SCR

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.

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 Related Circuits in the Library Circuit […]

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 Related Circuits in the Library Circuit #59 — Indonesia Light Sensor (SCR)

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 Downloads Related Circuits […]
