That wall clock stepper is a neat project. Fairly popular on Tindie. You can see a couple panelized boards assembled in this picture on Twitter: https://twitter.com/SmallBatchA/status/537258915613138944 His tiny design is significantly more popular, and significantly cheaper, than my own (albeit GPS PPS) clock on Tindie: Crazy Clock: https://www.tindie.com/products/nsayer/crazy-clock/ Jemma Clock: https://www.tindie.com/products/ptudor/jemma-clock/ ( And even more clocks: https://www.tindie.com/m/Clocks/ ) Patrick
