A while back I picked up a bunch of Wamco KW-104AL displays, which are tiny 16-segment incandescent displays, with the idea of building a FLW pocket watch. The pocket watch enclosure has a few advantages. First, it's OK for it to be a bit out-sized, compared to a wrist watch. Also, it has a stem, which can couple to both a rotary encoder and a button for the interface. However, I picked up a few pocket watch cases on eBay, and it's still a really tight fit. The displays are great, though - they're incredibly easy to drive, rugged, and I think they look very nice. They match the steampunk aesthetic of the brass pocket watch very well.
I really lucked out with the displays; I got a couple dozen for about ten bucks (plus shipping), and they all seem to be good. (I've used a lot of Numitrons - and the Russian equivalents - in the past, and they're a very rugged, tolerant, and long-lasting technology. I've never had one fail except when horribly abused. One actually broke open on my art car at Burning Man, and continued to function *without the glass envelope* for several hours!) ~~ Mark Moulding On Thursday, July 25, 2019 at 7:09:29 AM UTC-7, Mitch wrote: > > I've been wanting to design a word clock for a while.
