“SPIN transforms city streets into a playground for cyclists. This is made possible through an interactive handle-bar giving any bike a haptic interface to track personal performance and routes. This device consists of three sections: An intelligent light - blinker system, increasing the bikers visibility; a real-time buzz, informing you about things to look out while cycling; and a game...

release #001 afterthoughts

the first release of velosynth has been out for about nine months now, so it’s worthwhile to give the release a bit of review and see what worked, and what didn’t. here’s some collected thoughts and analysis: the whole device is too difficult to put together. very few people (if any?) were able to successfully assemble one. the breadboard + patchcable circuit-building process...

The Kickstarter Blog: Where Are They Now?... →

kickstarter: This past summer, people went a little loco for a little DIY tech project called Velosynth, an open-source bicycle interaction synthesizer that interprets the speed and acceleration of a bike into expressive audio feedback. Created by the folks of Portland-based tech/design group EFFALO, the…

Driving 5 Speakers Simultaneously with an Arduino →

interesting technique using interrupts — ”While the tone() function can only be run one instance at a time, I discovered (after much research), that I could hijack one of the timers (again, I chose timer2), and use some clever math and software interrupts to generate 5 tones simultaneously!”

release #001 shipped!

all of the kits, units, and enclosure systems from release #001 have been either shipped or hand-delivered. it was especially insightful to meet some of the local Portland folk and hear what makes them most excited about the project — so many different interpretations and ideas. as everyone in this release group gets their units assembled and working, we look forward to collectively exploring...
