After years of waiting to find the right hardware, I have finally found the time and the opportunity to build my own digital mechanical clock that uses absolutely no transistors or ICs. Its technology is reminiscent of the early relay computers from many decades ago. It uses 67 relays arranged in such a way to create 21 identical flip-flop logic circuits.
