    Geoff Graham’s Projects


    Over time I have designed a number of electronic devices and written a lot of software for microcontrollers and the Windows and UNIX/Linux platforms. Many of these projects have been just for the fun of coming to grips with new technology and I have built this website to publish these for hobbyists and like minded individuals.

    You might find that some of my projects are useful, others decidedly experimental, and still others rather specialised because they simply fixed a particular problem that I had at the time. This web site brings together all these projects in the one place.

    Please email me at if you have any comments or questions.

    On the left hand side of every page is the list of projects and articles that I have written and you are invited to browse through them or pick from the list below.

    I am a great fan of open source, so most designs include the source code, PCB layouts and other design files. They are free for you to use and modify under the following open licences.
