Most of the Electronics projects we have been involved in developing are protected by Intellectual Property Rights (IPR) or are otherwise confidential or secret in one way or another. Here are a few of our own projects that we are happy to release into the public domain.

PROJECT: BC DICE
Description:	Electronic dice game on a business card sized printed circuit board showcasing our skill in electronic design, PCB layout and low level software development (firmware).

Some of the software for the embedded controller (computer chip) that makes it all work.
And yes, It's a Linux editor!

PROJECT: SIMPLE SIMON
Description:	Simple Simon was a "Micromouse", entered into the 1993 competition run by the Institute of Electrical Engineers. A "Micromouse" is an autonomous robot that must find it's way to the centre of a maze and home again. The "Micromouse" that completes the task in the fastest time is the winner.

A Micromouse - Simple Simon as run in the 1993 competition

Simple Simon as run in the 1993 competition.
The robot is about the size of a house brick, powered by 3 x PP3 batteries with our own mechanics, electronics and software.
Simple Simon had a simple version of a Kinetic Energy Recovery System (KERS) similar to modern Formula 1 cars.
As Simple Simon slowed down before turning, the motors were used as generators while braking
and the resulting current used to recharge the batteries.

The actual maze from the 1993 competition, our smaller test track and Simon's certificate.
