So if you're interested, I could send you one when it's finished.
Personally I could make use of one. I think I have another three good displays here, so yes please. I can send you a bunch of 90v zeners if you want them. Used, but good. Use 1/2w for the 100k resistors. Nicko told me I didn't really need to use 9k1 resistors, 10k will do just fine. 9K1 was on the Bally board design I copied. ITEAD use the same factory as Seeedstudio (yes three eees) so it's pretty much down to any cost variation whom you choose. I cannot read a DCH file, so I cannot comment on that. Can one of the EEs here look the schematic over? It looks OK to me, but I am not very clever. You may need to experiment with a small off period to avoid partial ghosting on other segments. I do my all display routine calculations during the off period, fishing for the correct ASCII character and wanging the correct segment pattern out, so I don't actually have any additional delay as such. I find there is a sweet spot where you can get a crisp bright display by adjusting the voltage. Good luck with sweeping those sixteen digits at a constant rate. If you get timing variations you will see the ripple. John S -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
