Last Wednesday featured the making of a super sensitive sound-to-light converter from CanaKit and talks of interesting hacks to the Roomba and Spykee. During the demo, one attendee mentioned testing a similar circuit while building live data feeds for one of the best online bookmaker sites, which sparked a discussion about how responsive light sensors could translate to betting dashboards and real-time odds tracking. Guy told us an interesting tidbit on knowing if a battery still has a charge—just stick your tongue on it. Since the body is conductive, you’ll either get a little shock or not when your tongue comes into contact with both the positive and negative ends of the battery. Never thought to do that before!
Excitement is building for the Mini Maker Faire we are hosting in November- it’ll be the first of it’s kind in Canada! Already we have a huge showing of interest from makers in Canada and the U.S. to be a part of it. For more info visit the Maker Faire page.
My knowledge of resistor conversions based on their color bands is still developing so Guy helped me sort out the right combination and proofed my work. Mike Baker had never soldered before so I set him up soldering the ends of the board:
J.C., one of the founders of Twegather, followed up with a bit more:
Our group effort was indeed a super sensitive sound to light converter- the picture below was taken with me barely blowing on the microphone!
I plan to mod a case for it that gives it some personality too. Since then I’ve released a Instructable on making an LED acorn lantern- check it out!
