WiFi Accelerometer + LED prototype demonstration

Preview of WiFi accelerometer boards under development for an interactive installation at Austin First Night.

These boards utilize a PIC 24F series microcontroller to read 3-axis accelerometers 20 times per second and send the data as OSC (UDP) packets over a standard 802.11b connection. They can run in AdHoc mode or connected to an access point.

The boards also accept incoming OSC data to control the on-board or external LEDs. PWM is done at 1KHz with a 12-bit color depth. The camera unfortunately doesn't do it justice, but they are BRIGHT!

Power is provided by a single lithium battery with a current draw of around 1A at full brightness. I'm still tweaking the LM3410-based constant current drivers, so this will get a bit more efficient. Charging is done via an onboard Li+ charging circuit.

Eventually, the boards will be mounted in acrylic swings which will backhaul telemetry of people swinging to create an interactive soundscape, and the lighting on each swing will be individually controllable.

Collaboration with Danielle and Jason Mika, and Jonny "5" Sylvan.

very neat would like to know wich wifi module are u using, it seems like a break out board to me of so it would be awsome to know where i can get one

@tudador The WiFi radio module is a Microchip MRF24WB0MA (technically, this is the earlier ZeroG module, before Microchip acquired them)

hi i want to control a circuit by wifi, you can help me with a list of items to start investigating, thanks
