If it has to move with thermal expansion, if oxidation might be the problem' try thermal cycling a bunch of times.
Interesting project. You will have to show us when it is perfected.
The unforgivable production flaw is that segment 'c' is drawn in the wrong perspective. I can't unsee that!
They're like Frankenstein's poptarts. Part of this delicious breakfast.
How about just using rail to rail op amps for driving. Some of those can easily handle 30+ volts, and if you run them as comparators it should work. The inverting input is at a 2.5v bias and the noninverting has a high value pull down resistor to ground. Output is connected to ground in this case and the display segment is off. If a logic 1 (5v) comes on the noninverting input, output goes to B+ and the segment is on. You can get away with either 4 dual op amp chips or 2 quad op amps per segment.
Fantastic
The classic CD40110B CMOS counter/7-segment display driver might drive it, if 20 V (rather than 24 V) will suffice? If not, the MAX6920 series VFD drivers are rated to drive up to 76 V, 40 mA per segment, and certainly will.
hey Fran. I used to work in an Norwegian antique store,, i think your clock should be sold for no less than a million in any currency.
cant wait to see it
That half volt variation would be a really cool animation to cycle when segments are on, or would that be too destructive?
I think you will get problems with heaters in series as the cathodes will be swinging well away from the center tap 0v on the ends of the chain. Parallel with 5v centre tap..
Use some NE594s. It'll simplify the circuit. You can get them from ebay.
Those segments look really cool, almost have a 3D effect to them
might be worth vibrating the open circuit VFD to see if the contacts will "make" again. tape it to a phone and keep calling it maybe? XD
If at first you don't succeed,
Follow Directions.
Knew you'd nail it! Not only that but you used one of my favourite words, "notwithstanding". Excellent work!
