Nixie Tube Clock based project based on existing code and boards by Ogilumen and RobotPirate
The current project uses an Arduino Uno and the Arduinix Shield from RobotPirate. The code is an extension of the sample code provided by the latter. The PCB for 6 nixie tubes was designed based on the .pdf schematic available in Arduinix.
As of 2019, the current design uses a bluetooth module (HC-06 or HM-10). The use of HM-10 was chosen since it's a Bluetooth 4.0+ module that allows it to work with both Android and iOS apps.
