It’s been a long time since I started the rework of my nixie bargraph clock. Probably about a year, but I can finally sit back and say it’s finished. I plan to make a few, one to repair the original instructable clock and this one which I mounted on a piece oak.
The numbers have been laser etched with the tubes held by copped pipe straps. The board is mounted on the front with a protective acrylic screen. Exposed PCBs aren’t to everyone’s taste but they are mine. There’s a little RGB LED which indicates which mode the clock is in: set time, calibrate hours tube, calibrate minutes tube. Knowing that the tubes have a limited life span I added some code so they turn off between 1am and 6am. All pretty straight forward stuff. Now it hangs on the wall looking ace.
