Re: [neonixie-l] Re: HV Meters For Nixie Testing
Here's a 500VDC meter: https://www.ebay.com/itm/120990711589?hash=item1c2b9bbf25:g:Y~AAAOSw9KZiTu0p If you go hunting around, you can find sellers that have a bunch of different ones. I've gotten addicted to these things and I've probably got close to a dozen of them in different things in the workshop to monitor voltage & current. *Terry* - I sent you an invite for the HVPS1 google group where you can get all the details of the power supply in the photo. I sold all of the PC boards to others (mainly for cost of shipping) who I hope got a chance to build their own. The 10-turn pot controls a current-limiter, so it runs at less than 1 watt. Take a look at the design report I posted on the forum and let me know if you have other questions.

[neonixie-l] HV Meters For Nixie Testing
This may be interest to many here. I have the PRO Nixie Tester: https://nixietester.com/project/pro-nixie-tester/ And I'm searching for a pair of digital meters to go with it. I can live with a voltmeter that only goes up to 199V DC but 300V would be better. What I'm really unsure about is a digital ammeter that can handle at least 20mA at these high voltages. The precision should be at least a tenth of a mA (for working with IN-9/IN-13 at least). Yes, I know I can go over to Harbor Freight and get a couple of cheap DVMs and cobble something together but I need a display large and bright enough for my lousy eyesight. A couple of DPMs with bright LEDs would be perfect and take up much less space. A friend of mine bought a K40 laser cutter recently so I'd be able to cut an acrylic enclosure to match the PRO Nixie Tester.

Re: [neonixie-l] Reboot of an old clock kit design
Thanks Allen! Email me direct, I'll help you troubleshoot it or you can just mail the clock to me and I'll take a look. I still have various spare parts for repair. Save for a year or two of sitting in a box.. the first production, serial #1, 6 digit clock is still on my lab bench. Been running for 15+ years now I estimate. I remember we all used to talk about tube lifespan.. these ones are still the originals and are still working!

Re: [neonixie-l] Reboot of an old clock kit design
Welcome back! I’ve got one assembled 6 digit z57xm clock and believe it or not another kit that is still in its box. The one I put together ran for a number of years and developed a problem. I don’t remember exactly what at this moment. I am very interested in the new project you are working on. I’ll buy one 😊 Allen Wisbey, W1SBY > On May 17, 2022, at 1:17 PM, Moses wrote: > > Hello Everyone! > > My name is Moses. This is my first post here on the new *google* neonixie-l > list.

[neonixie-l] Re: Reboot of an old clock kit design
Hi Martin! Thank you! Yes, I wrote the code for the 6 digit (and 4 digit) clock controllers. Those were actually offshoots from the original clock kits. Someone approached me to sell the controllers separately, and with a few code changes the controllers were born. Still sell a few here and there to this day.

[neonixie-l] Reboot of an old clock kit design
Hello Everyone! My name is Moses. This is my first post here on the new *google* neonixie-l list. I used to be on the list when it was on yahoo groups, 20 some odd years ago. I never switched over to the google group until now. Like they say, life is what happens when you're busy making other plans. I hope some of my old friends from the list are still here, and I'm sure I'll meet some interesting new ones as well. A little background on myself. Back in the early 2000s after loosing my job. I'm not exactly sure how or why.. but I ended up traveling to the other side of the world, many times, roaming through dusty old Soviet warehouses looking for nixie tubes. Those stories can go on for days, I'll keep it short for now and tell you it was an incredible adventure! I brought those old tubes back here to California and started selling them on ebay. I would eventually make several clock kits using the tubes I had, including a 4 digit IN-17 kit, and 4/6 digit kit with Z57xM tubes. I never made the riches that I had anticipated, but it put food on the table for while and it was fun work. I am the original owner of the domain 'neonixie.com' and you can see some of my original clock kits there. Fast forward to now. I've decided to redesign my most popular kit, the 6 digit Z57xM kit. You can see the original here: http://www.allspectrum.com/store/digit-red-filtered-z57xm-nixie-tube-clock-kit-p-130.html I've kept the size of the board the same as before, but everything else is new. Some features: - Controller choices. The board will accommodate an ESP32 or a Pi Zero. I've picked these two boards because of their popularity and the fact that they have wifi. It is so nice not having to set the clock! Wifi and NTP! - Modern HV drivers, HV5122/H - The tried and true MAX1771 for the HV supply - Pinout for optional DHT22 temp/humidity sensor - Pinout for optional BH1750 light level sensor to dim the tubes at night - Prototype area for custom sensors/etc. Pictures here: http://neonixie.com/Z57XM6DV2/ The actual pictures are of the first prototype with an ESP32 attached. The 3D rendering is of the second prototype which I am about to order. I believe the second prototype should be very close to the production version. Now on to the point of this post. Before I order the second prototype, I would like to know what people think of it. Comments about the overall design or any specifics, what you like or don't like about it. Any changes or additions you would make? There is still time for me to make changes.. so if there are any other standard pinouts (like for the light sensor/etc) that I can easily add I will. This was my first real experience with the ESP32 board and it works well in the design along with the Pi Zero which has a big following.
