People think they are ugly until they see them. Tubes with nipples on top - now *they’re* ugly. On Friday, July 29, 2022 at 1:02:41 PM UTC-4 Pramanicin wrote: > Not dissimilar to NL934's, and they're quite nice looking IMO. Each to > their own! CD47's, now they're *fugly*. > > On Fri, Jul

The best source of data on Japanese tubes is this one: http://www.boreas.dti.ne.jp/~sd1250/nixie/nixie-data.html The closest tube that matches is LD8022, which has the correct manufacturer and envelope, but an additional symbol. On Thursday, July 21, 2022 at 5:01:29 PM UTC-4 Bogdan Paduraru

[neonixie-l] Re: IN-18 What is between Pins 1 and 8?

It is a capsule that contained mercury. It was heated up when the tube was manufactured to release the mercury. The addition of mercury to the tubes vastly extends their lifetime. On Tuesday, June 14, 2022 at 10:15:13 PM UTC-4 lawill...@gmail.com wrote: > I recently got some IN-18 nixies and

This is one I made a while back. It uses the tube socket pins that LB(?) referred to. I see it isn't very well labelled, in terms of what value of resistors to use, and it uses surface mount resistors. Anyway, there it is. https://oshpark.com/shared_projects/G9c1wPoq On Monday, May 16, 2022 at

[neonixie-l] Re: Leading 0 (10s hours) in direct drive of nixie clock - are stray effects any concern?

8.9k would be correct for 180V. You don't need to figure in anything else for direct drive. If the software/hardware uses PWM to control brightness, it will still be expecting 8.9k resistors. If the display is actually multiplexed, that would be different. On Thursday, May 5, 2022 at 10:43:16

I feel there should be a pinned thread titled “I can’t believe the price of tubes these days”. Don’t get me wrong, I also gasp at some of the asking prices I see! Love those IN-18s. I would love to have a set, but I’m not sure I could justify the asking price, and I really need to make clocks
