Your eyes are too slow for this clock

Mitxela's Precision Clock Mk IV is so precise, you can't see it. The last two digits, that is... not even the fastest high speed camera I own can clearly see the rollover of the last digit! I bought my clock assembled from Mitxela, and the batches sell out quickly once made—so you may or may not be able to find a kit or assembled version, but Mitxela also shares the firmware and hardware production files too (they'll be up soon) if you want to make your own!
