Interview with Todd Harrison @ EEWeb. SpokePOV!
I’m working on several projects almost perpetually. Getting the time to complete one project before being distracted by another is the real trick. My most current project which is almost done is running my bicycle tire in a test rig using a scavenged AC motor. The test rig is so my daughter can work on her SpokePOV kit from Adafruit at the lab bench and the motor will make it easy to spin up the wheel to check the image and/or animation. It takes longer for these projects because I document it all and shoot video for my ToddFun blog. This build includes welding, repairing the scavenged motor and building a 120v AC to 15v DC power source to run a cooling fan to cool the AC motor. The cool part is I built the 15v DC source using only a light bulb, diode and capacitor and showed the viewers how to correctly calculate the required wattage light bulb and what is important to get it right without getting into too much engineering.
