Andrew's DIY Casio F91W Smartwatch: The Ollee Watch Board
At 23:47 · chapter starts 21:10
Andrew discovered a YouTube video about the Ollee Watch replacement board — a $50 circuit board made by a single Canadian developer that slots into a $25 Casio F91W and adds Bluetooth connectivity. The mod keeps the original screen and buttons but adds an accelerometer for step counting, automatic phone time sync, configurable watch faces, and a phone app for logging timed sessions. It even supports blackjack. The creator ships every order on Fridays no matter when you order, underscoring just how small the operation is. Andrew loves it for the tinkering experience and sees potential if notifications arrive in Q2, though David debates whether the Casio board adds anything the Fitbit Air doesn't already cover.
