I never decided on a particular display to use. I was thinking along the lines of 192x32 LCD displays. LEDs could be used, but I didn't see any alphanumeric LEDs on Ebay that were small enough. I didn't check places like Digikey. Also, doing the annunciators with LEDs adds some complexity (like doing a mask for regular LEDs... I would use something laser cut... maybe via those cheap stainless steel sold paste stencil services.
The replacement front panel board has been a back-burner project for when/if my display crapped out. Since I now have some VFDs (and if they work) it's an even more back-burner project. It's definitely doable and should not be too difficult. By the time I found the displays on Ebay, the guy had sold out. I sent him a message and he did still have some. He is in Germany and the cost worked out to around $200 for two displays shipped. Here is the original listing. His email address is towards the bottom of the listing. https://www.ebay.com/itm/Agilent-HP-frequency-counter-display-ITRON-cc1187g-/222736101378?hash=item33dc1b3002%3Ag%3A3vIAAOSwJtdaHWu6&nma=true&si=AAyIqjuDMKPyvv8Dzk7zOQOPZXw%253D&orig_cvip=true&rt=nc&_trksid=p2047675.l2557 I saw a comment that there might be an aftermarket display that has recently been built (like the replacement VFD displays available from China for the HP benchtop DMMs). -------------------- Hi Mark - will it drive LEDs? Are you going to build some of these up? Are there more VFDs available on eBay? _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
