Thanks for the explanation ... looks like anything is possible, it is the execution is tough. Oh well, at least I have a backup display in case one of my DMDs go bad.
Appreciate the time. ron On Sunday, December 27, 2015 at 10:06:16 PM UTC-8, gregebert wrote: > > From another thread: *can you make a clock out of a Williams DMD display?* > > The answer is yes, you can, but it will be considerably more complex than > a nixie-tube clock.
