The circuit is very important as it features heavily in KS4 curriculums. It has been designed to have more than one possible outcome and therefore more than one application. It allows for good differentiation and includes a transistor drive circuit.
Time can be varied with the variable resistor
Can be used with various trigger inputs
Battery-powered
PCB has space for a transistor drive circuit to allow higher powered outputs to be added
Clear silkscreen text has been used to make construction simpler
Professional double-sided PCB pre-drilled with silkscreen and solder-resist
Empty PCBs are available separately, order code 70-9034.
