My original mounting idea wasn’t going to work: It’s not obvious, but there would have been no way to manage the wires with the case. There would have been too much tension. I opted to cut the front plate off the top case, and then mount the tubes there. It looks like this… The vice-grip [...]

Test mounting the PCB: I drilled these mounting holes freehand. I’m only off by about 1mm. Not bad, I guess. The first “live” test: This is connected to the LSB of the minutes, since I won’t be using seconds. Had to crank the HV up all the way. I’ll have to drop the current resistance [...]

You might wonder why I’m taking time doing this. The main reason is that it’s been a long time since I did any kind of serious project, and this is the first one I’ve done. Building PCs out of plug-and-fit components doesn’t count. I used to work as a electronics bench tech, and after three [...]

See below, regarding the nixie clock kit which I am building. Below is the finished board. All components installed, and I tested all the voltage levels, and all looks well. While I was testing the HV, I quickly tested one of the tubes. Now I need to get an enclosure, and mount the board and [...]
