This is a kit to build a simple flashing LED. All components are supplied (except a 9v PP3 battery) including the choice of red or green LED. The kit should take no more than an hour to construct. All component values and orientation are printed on the circuit board to aid building but a full circuit diagram is downloadable below.

I produced this kit as an introduction in building a kit from a circuit diagram. Start by soldering the low profile components first and continue in size until finally, fit the battery connector.
