For those who are interested. Here is a picture of the timer from when it was still mounted on it's breadboard.
A cover makes all the difference.
The timer is developed on a PIC18F13K50, from Microchip, with a 31Khz crystal harnessed for accurate timing.
Other than the display, a buzzer, an LED and a few switches and batteries, there is not much else to it really.
