This Shower Timer was made by Thomas Stratford. It is a modified version of our Shower Timer Kit, Thomas has added three super bright blue LEDs by using a very simple transistor driver circuit built on a piece of stripboard. He changed R2 for a 10k resistor to drive the transistor and removed the CR2032 battery holder so that the circuit could be powered by 3 X AA batteries.
You can see the schematic and the stripboard below the pictures of the finished kit.
