The Time Machine Mk. V is an upgraded version of last year's Time Machine Mk. IV. It uses the same processor, but adds in a bigger battery, a serial port, and a debug port. The battery is a CR2032 which is four times larger than the Mark IV's CR1225 battery. A utility port allows for easy firmware upgrades and debugging. The Mk. V is better than the Mk. IV in almost every way, and I'm super happy with how it turned out. I also made a special blue and gold version, inspired by one of my dream cars, the Subaru WRX STI.
Please check out the links below the photos, especially my website! I put a full write-up there and I have some more projects you might like. Also, check out the short youtube vid, it shows some of the cool animations I've programmed into the watch!
Have you been watching the market for any possible rechargeable replacement for your coin cell? Also, is there a possibility of underdriving those LEDs to conserve power a little while still retaining visibility? The revision I'd like to imagine would ditch BLE but add USB for charging and/or syncing with a PC. Given that there are a lot of platforms to choose that run Espruino this might be relatively trivial to code (leaving the hard/fun part of the physical design). Please keep revising!
