I hope yours works correctly. Mine isn't; it seems to be stuck in some odd setup mode and I have no idea how to get it reset. Removing power & battery, and shorting the power pins did not reset it. Since it has HC595 drivers for the segments, I'm probably going to remove the controller IC, and drive it from a Raspberry Pi. For now, it's in the junkpile waiting for me to finish other projects.
This is the 3rd clock kit I've built, and probably the worst. The scope clock was the most complex, and has been working flawlessly for several years. In hindsight, it's probably a ripoff from David Forbes scope clock, which I suspect is a very well done design. Next is the edge-lit clock, and it worked fine for a few years, then after I tried changing the mode, the tens-hours digit started displaying the logical OR of the lower-order digits. This *has* to be some sort of software glitch. Anyways, it's a 5-digit clock now. All of my other clocks were designed and built by me, and they all work correctly. Go figure.....
