Nixie Tube Clock
Nixie tubes are awesome. These pre-VFD displays use a stack of punched-out digits 0-9 which, when charged, excite the neon around them in the vacuum tube, creating a beautiful orange-red glow.
This project uses old-stock Soviet-era IN-14 tubes. When it's finished, the clock will have 3 hanging lanterns with 2 tubes in each. It will display the time in hours, minutes, and seconds. The blue bottom-illumination can be turned on or off with a switch.
The time controller is the remote tube kit from PV Electronics in the UK. When I originally assembled the PCB, I did a terrible job. It was my first small-scale electronics soldering job. Major appreciation to Peter from the supplier, who spent a lot of time trying to help me troubleshoot the problems I was having, and finally sent me a second kit at cost when it looked like the first one was beyond repair.
I have had this project on the back burner for a long time because I haven't thought of the perfect mechanism for holding all 3 lanterns, the circuit board, and the control buttons. When inspiration strikes I'll be able to finally wrap this project up!
