Wow! I'm really impressed with everyone's generosity. I used to pretend like I was an electrical engineer about a hundred years ago, so I think between the stuff on Thugwold's GD and Nixiebunny's link, I should be able to get very close to a finished watch. Thanks again, everybody; I can't tell you how much I appreciate all of the assistance!! On Monday, December 12, 2022 at 9:25:55 PM UTC-6 nixiebunny wrote:
Thanks for posting this! It's not everything needed to figure out the parts placement, but the schematic diagram is a big step forward.
Good photos or scans of both sides of the bare PC board are needed to figure out which parts go where.
Long time lurker here.
The google drive link below has pictures that may be of use.
I can remove the plastic cover to shoot better pictures of the watch guts if that would help.
Found it. Thank you! Metalized Polyester Film Capacitors.
There was an issue with the original parts on the schematics. This was what Jeff did to fix the problem when I brought it to him.
I think the schematic you have is for the original Nixieclock that Jeff made too. In 2000, he made 6 of them to give to friends and clients. I have 5 of 5 (of 6.). Note the replacement resistors he added later. Can anyone identify them. The big yellow things as pictured.
They look rather like mylar caps and have a rating of 250V. Perhaps 2k2 = 2200pF?
