Thanks for your explanation about how to configure the reference resistor and ghosting. This really is the best of UA-cam. Beautiful clock, by the way. VFDs have an otherworldly appeal.
Thank you for the shoutout and I'm so glad you were able to put the information from the document to good use! It's nice that you covered all the key points in your video. And yes, the bias applies to the center tap when using a center tapped transformer, but in general it applies to the the filament voltage itself of course, however it is produced. So for example, if you use one of those "tilted" displays and were powering it via DC, you would still want a positive DC bias for the same reason. The clock is really taking shape, looks and works great! On the topic of filters, just my 2 cents, but I personally like the natural green phosphor color, so I wouldn't go too crazy with color. Did you know that if you use a red filter, the segments will appear white? Orange will make them appear yellow. If using a filter at all, my personal preference with these tubes would perhaps be a slight smokey tint, but in the end, it's whatever appeals to you. Again, just my 2 cents. Great video BTW, and I enjoy the longer videos. Will enjoy seeing the final build when it's ready!
Thank you again for the supportive complements. I did try to get across all the points with my chopped up way of speaking thru low budget extreme editing. (watch the seconds count on the clocks as I speak hehehhe). Filters, yes good to know on the other colors. I feel the same with the natural phosphor color, I like it the way it is. That is one reason why I was leaning toward the smoke tint I already have on hand and that is the other reason, I already have it on hand LOL. I do have to add, if I had to use a colored filter, blue would be it. That Aries clock I rehabbed recently looks pretty good that way. More vintage style builds planned....maybe a free form as well checking out some of yours! Nice work!
Nice work Jim, it looks great! If you want to improve the contrast, a green or blue filter would really make the lit segments pop. Using one of those small VFD tubes as colon separators would look nice, and some Soviet clocks did just that.
Thanks Matt. After thinking on it for a while, I really think I may use the smoke tint for two reasons: I like the natural color of the VFD and I already have the smoked tint on hand. It seems to offer enough contrast. I am working on integrating the IV-3 colon tubes to the existing circuit as we speak. Thanks again!
@@JIMO415 That's fair, it's a personal preference thing. The Soviet VFD tubes are bright enough that they don't NEED a matching filter to be readable in bright light. Hopefully adding the colon tubes worked out okay.
Thanks Jim for sharing this nice clock. I have some IV-11 tubes, so you inspired me to try building one by myself….can you please tell me where I can find the schematic ? Thanks Stefano
Can you screen shot it from the part 1 video at 8:43? ua-cam.com/video/H3iAr_EtzxQ/v-deo.html Or I can send to an email if you feel comfortable leaving one here... If those options do not work, let me know.
@@JIMO415 Dear Jim I wrote you two times with my email address…but I can’t see it. it seems that my messages are deleted. So I don’t know how to write to you. Any ideas ? Thanks Stefano
@@stefanobozzini6353 you can try one more time to send an email but use "at" for @ and use "dot" for the actual dot. If still no luck, let me know again and I will try to leave mine which I do not like to do as it is my only one. Good luck. Thanks

Thank you for the comment and your interest. VFD's are something else!

The digits look great. I still like the old wood box for a case but your boards did turn out looking nice for a clear case. Tough choice, good luck.
Thanks. I have to yet decide on the case...I am thinking clear at this point.
Love it. Nice job!
Thank you!
