About the Divergence Meter Nixie Board

Divergence Meter Nixie Board is an open source PCB design by q61org, published on GitHub. It is a 2-layer board measuring 188.5 × 42 mm, with 45 components from 18 distinct parts.

Other key parts include the 74HC595 and SN75468. By type, the board carries 9 ICs, 8 relays, 7 capacitors, 7 resistors, 3 connectors and 2 transistors.

It belongs with the displays & leds designs in this gallery.

From the project

A divergence meter that tries to look just like the one in the anime.

This is a serial-to-parallel converter board with nixie drivers. It is designed for NL-902 or NL-842 nixie tubes.

This board needs a high voltage power to ignite nixie tubes. Be careful when handling high voltages. It can kill you.

The left half of this board is designed to match with the dmcontrol board. You can solder pin headers to P1-P3, and they mate with P4-P6 of dmcontrol board.
