This is my first nixie clock design. It's six-way multiplexed using high-voltage opto-isolators (TLP-627), with an Atmega168 for the microcontroller. These are Russian IN-12 tubes using a Russian 74141 BCD chip. Features include: 1F capacitor for back-up power during an outage, alarm functionality and audible feedback during mode changes, and a 3-axis accelerometer for all interaction.
Case is red oak, walnut and plexiglass.

Hmm…it looks like things are taking a while to load. Try again?
