Mechanical watch enthusiast Jake Bordens wrote in to share his latest project, the Arduino Watch Winder. Wanting to keep his watches on display, he needed a solution that could automatically wind them so their time would be accurate. The (expensive) commercial device that he had worked well when he only had one watch, however it couldn’t support winding two watches at different rates. Instead of purchasing a more complicated model, he decided to take matters into his own hands, and used an Arduino, Ardumoto motor driver shield, and RTC module to run the winding motors independently. It’s a bit of an obscure problem, but a nice hack, and it could come in handy if you have a task that needs to be repeated each day at a specific time. Full source code and explanation is available at his site.
