Nixie Tube Clock | 0x7D.com

A very nice project report on the design and build of a simple Nixie tube clock including an unexpectedly in-depth section on the design of the custom flyback boost converter. The tubes are driven by individual transistors, controlled by an stm32 uC, powered and programmed over USB-C, and housed in a custom machined stainless steel case.
