If you’ve ever wanted to be like Steve Wozniak and have your own custom-made, geeky watch, Squarofumi (stylized SQFMI) may have the product for you: an open-source, Arduino-powered smartwatch with a 1.54-inch e-paper screen (via Gizmodo). It’s called the Watchy, and both the hardware and software are completely customizable. You can, however, use it right out of the box, as the PCB acts as the body and has points to attach a watch strap. And to top it all off, it’s only $50, on sale for $45 at time of writing.
The battery life SQFMI estimates depends on your use case — it says if you’re just keeping time you should get five to seven days, but if you’re fetching data frequently you may only see two to three. Its open-source nature, however, means that you could always fit a larger battery into it, or try and make some software optimizations if there are features you’re willing to cut.
