Version 5 of my venerable sensor system takes to the air, with 4 channels of lighting goodness, haptic sensors, and environmental sensors strapped on! Definitely making these Luxeon Rubix chips shine!

Version 4 of my multipurpose sensor system...with haptic sensors driving 16 channels of PWM on my own special board...

Version 3 of the sensor system...smaller, more power-efficient, and new types of sensors...here being employed to monitor fermentation...

45,000 lumens of lighting goodness, all from a $10 circuit board. When we tested these things for the first time, the cops came...

Version two of the sensor system, showing the data aggregation node, which collects data from the sensor nodes. This node hasn't changed much over the years. Must mean it's a good listener.

The very first versions of the ARTEMIS system, an ultra-reliable, real-time data gathering system. The first sensor nodes were designed to be able to be transparently installed in temporary power networks for QOS monitoring. Later, I added weather sensors, cameras, and other sensors to the mix.
