Well not really, I had to give up five of them. They are in a clock somewhere now, I traded them for some other tubes. Feel better? ;) On 1/22/2017 1:47 PM, Nicholas Stock wrote: Now that's just mean:-) Sent from my iPhone On Jan 22, 2017, at 12:44, jb-electronics

Re: [neonixie-l] Re: Interested in B7971

Many years ago I made a 16-tube array using B-7971 tubes. Made my own driver cards for them, one card per tube. Each of those cards has a storage buffer capable of storing the data for its tube. Each card has 15 driver transistors and 15 cathode resistors. Then I made up a data storage and

I just finished reading the article "The Molten Tin Solution" by Rachel Courtland in IEE Spectrum which explains some of the EUV chip-printing technology so this description was a nice view from another side of the complexities of producing ic's, especially as they talked about the problem

Re: [neonixie-l] NL 7094

I am not even sure if I woud ever build such a clock. For me these kind of tubes are too precious to be burnt off in some clock. Weird collector's point of view, probably. At some time I had quite a few GR10G (transparent mesh), and I considered building a clock with them, but I decided

Re: [neonixie-l] NL 7094

I get that Jens, but eventually they will fail...maybe not in 10 or 20 years, but eventually they will de-gas...? I'm a believer in enjoying them whilst you can...life is short. And hey, Dalibor is making new ones, so it's all good! On Sun, Jan 22, 2017 at 1:05 PM, jb-electronics

[neonixie-l] Re: Wifi adapter for NCS314

I transfered my breadboard implementation to perfboard so that it fits under the NCS314 shield. The last time I had made anything from perfboard was a RAM card for the Apple II. That worked first time. This way way way simpler perfboard took way too many attempts to get right. If I had a

Re: [neonixie-l] Re: black box from Czech Republic

Just to make it clear - one day, I would like to develop a big tube like CD47. We currently produce only the R|Z568M tubes (which makes our little team really bussy), the only new tube in development is the colon tube for Zen clocks. Best, Dalibor On Sun, 22 Jan 2017 at 21:32, Paul Andrews

Re: [neonixie-l] Re: Interested in B7971

Yes, I have specific per-segment current limiting. The circuit is simple (NPN transistor with emitter resistor). I aslo have a current-limiter at the anode. The problem with the 7971 datasheet numbers is that if you add-up all of the spec-value segment currents for an '8' character it's 40mA.

[neonixie-l] Re: How ICs are made - the inside track...

Thanks for posting. To put things into perspective, I was working on a 40nm project (the above posting mentions 40-40nm process technology) 10 years ago, and we actually switched it to 32nm. And that was also 10 years ago. A lot has changed since then. You wouldn't believe the things we did to

I started in PCB manufacture with 'punch and crunch' double sided PCBs and ended up maintaining 24 layer 4 thou track and gap equipment which was cutting edge at the time. Spent 11 1/2 years in CMP going from 64nm on 200mm wafers to 14nm on 300mm wafers. Now 7nm on 400mm wafers are on the

[neonixie-l] Re: Interested in B7971

I'm actually planning on designing my own PCB for it with exact current limiting for each segment as per datasheet. Did you do the same or did you install just one anode resistor and how important is it to stick to the datasheet in that sense? Dana nedjelja, 22. siječnja 2017. u 06:13:02 UTC+1,
