RK Education SCR / Thyristor Projects

This project introduces latching circuits and also other important concepts including different ways of triggering and resetting circuits. There are a number of possible outcomes for the circuit including electronic alarms, an electronic money box, a target game and a steady-hand game.

• Different trigger inputs can be used
• Different resets can be used
• Space for up to 3 outputs
• Battery-powered
• Clear silkscreen text has been used to make construction simpler
• Professional double-sided PCB pre-drilled with silkscreen and solder-resist
• Available in 2 versions: economy and complete
• Both versions are supplied with empty PCB, 1x PP3 battery clip, 1x 2N5060G SCR or equivalent, 1x 5mm red LED, 1x 270 ohm resistor, 1x 1k resistor, 1x 10k resistor (all 0.25W), 1x SPDT slide switch
• Complete version has additional push-to-make switch and 6V PCB mounting buzzer
• Empty PCBs are available separately, order code 70-9048
• Suitable for Key Stages 2, 3 & 4 (ages 7 to 16)
