In an earlier post, I brought to your attention a watch you could build yourself. Â If you’ve already done that one (or just are looking for something to do on a lazy weekend), this is another great (and affordable option).
Over at Adafruit, they have the Times Square, with a display driven by 64 LEDs enabling a sort of scrolling marquee:
64 LEDs light up to tell you the time in a variety of ways. Built into the kit are 3 different watch ‘faces’ – a scrolling marquee with time and date, a binary watch display (for geeks, robots and binary fans), and a moon phase display (for beach-combers, werewolves). There’s also a built in battery meter so you can check your battery life.
Of course, with you getting 500-1000 uses out of a regular ol’ coin cell battery, battery life really won’t be too much of a concern. Â Though, with that scrolling effect (shown above), I think I’d burn through that battery in about a month after I first built it.
Now, understandably (given the DIY electronics inside the case) this is a larger watch, though the minimalistic casing seems to be keeping that as slim as it can. Â Should you want something that’s more rounded (and don’t mind adding bulk), you can 3D print your own enclosure; more info on that is here (and is pictured below).
Regardless of the case, at $30 (product page) this could be a very fun project for the more electronically-inclined watch afficionado.
