My first experiment is working with Neon lamp (dot type). This lamp has same characteristic with nixie tube. I used opto isolation chip TLP627 because it can isolate up to 300VDC. 

DC step-up module is used to convert from 12VDC to 150VDC to light on the lamp.

Here is video about my first experiment:

Main point of this experiment is to check if DC step-up module and isolation chip TLP627 can work together or not. Also, understand working principle of Neon lamp (nixie tube)

After successful, i will do with Nixie tube

Please wait until the project complete with nixie clock!
