Description

Cool Nixie Tube Clock, design works out of the box. All parts (execpt for the tubes) can be ordered from LCSC, if you have any questions feel free to contact me via easyeda messages. It is recommended to put the nixie tubes on special nixie tube pins, these can be found on ebay. I'm currently working on an enclosure.

NOTE:unconnected lines between top and bottom board are OK. The PCB is grooved in the middle, which allows the top part to be vertically mounted against the bottom board
