Yes, I’ll keep them also for a long term project ☺ Thank you for your notes!

I bought 4 of these last year on a whim because they are SO unusual Problem is, electroluminescent displays have a rather short lifespan, on the order of a few hundred hours. Not a good choice for a 24/7 clock. They operate on low-frequency AC, on the order of a few hundred Hz. Basically, the capacitive current energizes the phosphor material to emit visible light. They *will not* operate on DC. Also, you must not operate them on square-waves, as the high dv/dt will result in excess current. I plan to use a triangular wave, which results in constant current. I discourage you from using 50/60Hz AC from the mains, as it would require higher voltage to get illumination, which could cause breakdown I measured the capacitance of my display units (posted below), and as expected, larger segments have higher capacitance It's another project on the long to-do list.....
