The Maximite is a free and open source computer running a full featured BASIC interpreter. It will work with a standard VGA monitor, PC compatible keyboard and an SD memory card. The Maximite also has also 20 input/output lines which can be independently configured asGEOFF'S PROJECTS
Surface Mount is Easy . Using SMD or surface mount components is often regarded as difficult and to be avoided at all costs - but that is agreat waste.

Air Quality Monitor. This Air Quality Monitor displays the level of VOCs (Volatile Organic Compounds) in the air as a number and a graph over time. VOCs are one of the primary measures of indoor air quality and are associated with the "sick building syndrome". It uses a cheap sensor module (approx US$15) and can be build in less than an hour.GEOFF'S PROJECTS
Intelligent Fan Controller . The Intelligent Fan Controller is designed to control the noise generated by the fans inside your computer. It does this by varying theirGEOFF'S PROJECTS
The Micromite LCD Backpack is a low cost microcontroller running a powerful BASIC interpreter with a touch sensitive TFT LCD display.GEOFF'S PROJECTS
A nautical digital speedometer with a heading indicator. The only extra component required is a low cost GPS module which the Micromite can easily communicate with using one of its serial interfaces.HOME

This work is licensed under a Creative Commons Attribution-NonCommercial-ShareAlike 3.0 Australia (CC BY-NC-SA 3.0) 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 projects@geoffg.net projects (at) geoffg.net 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.NEW
