Lunar phase clock

We found a simply beautiful Raspberry Pi project over at Instructables: this¬†illuminated lunar phase clock. Using John Conway’s lunar phase algorithm (that’s the same John Conway who invented the cellular automaton Game of Life in the 1970s), some simple circuitry¬†(some soldering required, but this is an easy enough job), and a bit of elbow-grease for...

It works, but it’s not readable by humans: instead, you find out the time by scanning the QR code it outputs with your phone. Stewart Russell knocked this together not because he wanted...
