The SP-151 is durable; I built a wristwatch a few years ago with the same unit my father got as a sample back in 1974. In fact, the prototype on my workbench is still running after 5 years on the *same* charge I put on the Li-ion battery (yeah, the battery drives the display and the RTC).
Somewhere in my archives is a set of schematics for using Sperry displays as clocks; let me know if you need them. I recall the circuit requires some switching to get the segments to light, so a scope will be necessary for debugging. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
