Using the decoder/drivers and nixies from one of the Bell & Howell digital multi-meters, the same micro-controller with software, and a cheap 170v dc to dc power supply kit from Ebay, I built a yet another dice tower in a new form factor. This one is based on an old Heathkit HD-16. The HD-16 was a kit available in the late 60's and early 70's. It was used by HAM radio operators to practice morse code.
