One of the best features of this clock (I have one and have been messing with it a while now) is the up to 100 kHz refresh rate and an analog LCD driver circuit that makes the digits not flicker even a bit, even when dimmed, with a high speed camera.
That and the fact it's the highest precision clock display I've ever owned!
It is certainly not inexpensive, but it's more of an art piece than a practical instrument, unless your eyes can see in the thousands-of-hertz range!
- newman314 1y agoSuper random but I seem to remember that you were working on/testing a different time device/prototype recently in a GitHub comment. Can you perhaps refresh my memory? Been trying to find the reference and it's driving me nuts this am. Thanks.

Even most LED drivers are multiplexed, with each segment flashing for a short time then going dark. This uses a separate dedicated buffer for every segment. This design is important for working well with high-speed cameras, an obvious use.
