All Transistor Clock

As a teaching exercise for my “Technology for Artists“ class, we designed and built an all-transistor digital clock using no chips of any kind - as if we were back in 1960. (we cheated a little on the display) The schematics for this project are available by clicking the link below: If you are interested in the circuit fabrication techniques used to build this project, check out this video where I explain in detail: Facebook:
