We’re not sure if this is the best thing ever or a crime against nature – but developers have announced the first release of Velosynth, the open-source bicycle interaction synthesizer. released under a creative commons sharealike license.
It’s a small, hackable computer that a”ugments the cycling experience by interpreting speed, acceleration, and other sensor data into useful audio feedback.”
How Velosynth works:
a hall-effect sensor attached to the fork detects the presence of a magnet fixed to a spoke of the front wheel. a three-axis accelerometer within the enclosure can be used to detect turning, leaning, and tilting. sensor data is collected and transmogrified by the cpu, which provides both audio and visual feedback.
audio feedback is created using a digital oscillator circuit that is controlled by a digital potentiometer connected to the cpu. its output is amplified and sent to the speaker.
visual feedback is negotiated through a 4-digit, 7-segment display that shines through the skin of the enclosure. additional LEDs can also be added and controlled by the CPU.

Kits are $100. See Velosynth.com for details.
