I've wanted to build a watch for a while, after seeing quite a few featured on Hackaday. A while back, I made a BOM for the project, though I never went through with ordering the parts. Originally my plan was to use an Arduino Pro Mini, but the Trinket is cheaper, and comes with the awesome Hackaday logo! Sadly, the Hackaday trinket is only available in a 5V configuration, and the LiPo batteries that Adafruit sells only come in 3.7V. So I had to order the 3.3V Trinket directly from Adafruit. The BOM is posted, and hopefully I can get some prototypes up and running soon!
