Depends upon which segments are bad; you can still get many characters to display. Also, are the failed segment(s) completely dead, or do they have signs of poisoning ? You might be able to cleanse those with more current Originally, I had no intention of using 7971's because I'm not a big fan o

I think this may be the clock Elektor published in 1975 - it could use either Mintoron or LED displays. I've uploaded the two copies of Elektor to the group's library at https://drive.google.com/drive/folders/0B93DAeV7sPGsc1hfaTZrMG9ZS3c

Cheers for those Nick, got to love those 1970's PCBs. Very rounded and, er, blobby. They follow the illustration style of the time. Ian On Tuesday, 8 August 2017, 16:43, Nick wrote: I think this may be the clock Elektor published in 1975 - it could use either Mintoron or LED displays.

Thanks, Nick. That one is close, but the one I'm looking for had a two digit display, and it was built on two breadboards. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group. To unsubscribe from this group and stop receiving emails from it, send an
