Just blew up (literally) two LEDs, burned four resistors, killed an Arduino and shorted something else. Hardware will cut you. on January 24, 2012

    That’s a 120V mains plug in a cardboard box and a switching power supply, which I’m happy to report did not cause any fire or death when they were plugged in for the first time. on June 15, 2011

    Arduino: Control LEDs with a Potentiometer on April 2, 2011

    I’m finally starting to try out some things on my Arduino after getting back to Edmonton. I want to make a bike computer for when I’m riding on my stationary trainer. Normally I would use my iPhone and Kinetic, but that doesn’t work when you’re not actually moving. I ordered some Hall effect sensors to sense a magnet attached to the rear wheel and figure out speed and distance “travelled”. Hall effect sensors suck, by which I mean I’m too inexperienced to figure out how to make it work effectively. So now I ordered some reed switches and am waiting on those. They require less components than the Hall sensor anyways (the jerks). on March 23, 2011
