How About A Nixie Clock

[Soul Tramp]

Picked up the board and tubes on ebay. Thought it would look cool in tweed. Surprise gift for my grandson.

Does your clock keep good time? Mine runs fast about 2 minutes per month. I thought they would be more accurate with a quartz crystal generating the time clock pulses.

I don't know. My grandson lives on the opposite coast. I'll try to remember to ask him over Thanksgiving, but I doubt he'll know.

No issue, I like mine even though it is not as accurate as I thought it would be. I would prefer that it would be a bit slow, then I could just add a minute or two each month. Because it is fast, I have to cycle through the whole hour and sometimes I get a switch bounce and then I have to do it all over again.

That's the coveted interaction with vintage electronics I keep hearing about...

I have a 240v clock radio that loses 7 minutes a day due to running on inverted power for 14 hours a day.

What does the inverter waveform look like? Modified square wave? PWM?
