A self-tuning, wide-bandwidth portable RF jammer. The device is lightweight and small for easy camoflauging: it is the size of a pack of cigarettes.- Completely redesigned from the earlier 2004 version.

"In a high population density city, inhabitants must be prepared to defend their own personal space. Technologies that increase personal productivity are on the rise, even though they may intrude on others. The unavoidable reaction is to create technologies that counteract other people's devices. Wave Bubble is a product that counters the all-too-familiar annoyance of loud ring tones and overt cell-phone conversations in public.

Part of the "Social Defense Mechanisms" projects designed for my MEng thesis.

This project is now available with detailed documentation

Electronic lighting subsystem design and manufacture at low cost, constrained size and adverse operating conditions. 240 red LEDs are individually controlled and modulated to create accent light patterns on a 30' diameter metal sculpture.

Project documentation coming soon!

A redesign & rerelease of the MiniPOV kit, this one can be programmed through a serial port (as opposed to parallel port only).

A little persistence-of-vision toy: when waved in the air, the LEDs 'write' out an image or message. In particular, MiniPOV was designed with the intention that it would be sold as an inexpensive kit for people to play with microcontrollers and LEDs.

A small & simple, but very powerful USB charger for an mp3 player, camera, cell phone, and just about any other gadget one can plug into a USB port to charge. The charger circuitry and 2 AA batteries fit into an Altoids gum tin, a high efficiency DC/DC converter circuit creates 5V standard USB voltage.

More information on design and construction is available at the MintyBoost page.

A simple, yet extensible sensor interface system for artists, musicians and others interested in experimenting with sensors. The MIDIsense boards provide a simple way to integrate various common sensors with existing software such as Max/MSP, Ableton Live, etc. or directly to a synthesizer/sequencer with a MIDI in jack.
While there are other projects with similar functionality, this one is the most technically advanced, flexible & inexpensive.

More information on design and construction is available at the MIDIsense page.
