velosynth is an open-source bicycle interaction synthesizer. it interprets the speed and acceleration of a bicycle into expressive audio feedback.

KITS & UNITS SOLD OUT, BUT:

enclosure kits are available for $20 so you can roll your own — this includes the enclosure, bungee cords, mounting velcro, a 3D-printed spoke magnet holder, magnets, and a hall effect sensor. add your own hardware and electronics!

velosynth is an open-source bicycle interaction synthesizer. it interprets the speed and acceleration of a bicycle into expressive audio feedback. this feedback loop helps to increase awareness of the cyclist within the transportation environment — much to the same way one can both hear and see a vehicle approaching. it is designed for user modification, completely open-source, and released under creative commons share-alike license.

after a year of research and development, we're very excited to offer a super-alpha, hella-low-level kit. this release is primarily aimed at hacker-savvy cyclists familiar with microcontrollers, electronics, and programming.

it is our hope that these kits end up in the hands of creative, self-starting individuals keen on sharing their ideas and documenting their work. we believe in open source and need your help to explore the possibilities of bicycle-based computing!

we're operating under a very tight timeline and razor-thin margins to get these kits delivered to the right people for a whole summer's full of hacking and experimentation. needless to say, we'd appreciate your help in spreading the word to anyone you think might be interested.

    everything you need except the batteries! this hacker-friendly, super-hella-low-level DIY kit includes a jeenode (arduino-compatible) microcontroller, three-axis accelerometer, and all the electronic bits to make some bleeps and bloops on your bicycle.

    a hand-built velosynth made just for you, completely patched up, and a reasonable amount support to get it up and running. beware, you'll still need to have some familiarity with microcontrollers and such; this is just a quicker way to get started, albeit more expensive.
