This week on Maker Update, a Neopixel puzzle project, tickling the toe beans, machine learning plushies with micro:bit, and a cyborg funhouse.

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, lights that synchronize with your heartbeat, a $30 synthesizer kit, cardboard pinball, modified NERF guns, heat shrink, Pi shims, and a good, fast wood finish.
