We want to make objects that delight people — and nothing kills delight faster than a dead battery. In this talk, Joey Castillo will show you how to build devices that sip power by the microwatt, instead of gulping it down by the milliwatt.
*About the Speaker*
Joey Castillo is the creator of Sensor Watch, an open hardware smart-watch that re-uses the case from a ubiquitous classic, the Casio F-91W wristwatch.
*About Teardown*
Teardown is a yearly event hosted by Crowd Supply that draws hackers, makers, and engineers from across the US (and the world) to meet together in Portland, Oregon. Teardown is about the practice of hardware: prototyping, manufacturing, testing, disassembling, and circumventing, all while having fun. Teardown attendees can expect lively talks, demos, art installations, hands-on workshops, fiendish puzzles, and lots of good food. Check it out! crowdsupply.com/teardown
*About Crowd Supply*
