I recently broke down a used kid’s bike and was surprised how many cool materials I found that could be reused for other projects. Even just the parts taken from a single wheel could be reused a number of different ways.

This week, a Kalimba made from teeth, Arduino gives the Yun a second chance, hacking a greeting card sound machine, a giant button for $1, and 5 maker materials you can cut from a trash bike. This week’s Cool Tool is a Greeting Card Sound Player Module.

This week on Maker Update, Donald runs through a list of projects he’d like to accomplish this summer. This week’s featured Cool Tool is the d.light S2 rechargeable LED light. 

This week on Maker Update: a motion activated bike light, a new, better Raspberry Pi Zero W, a tiny retro Apple II, a stunning animated LED lamp, a time travel TV, e-ink displays, a board for car hacking, and easy fiber optics. SUBSCRIBE ON YOUTUBE.
