our site!I did look at the Wemos D1 too.. but decided for this iteration I'll go with the controller I already know. For something smaller I was also looking at the Adafruit QT Py as well as the Seeed Xiao boards.I couldn't figure out how you power your IV-9s.Regards,-MosesOn Friday, December 9, 2022 at 2:47:58 AM UTC-8 Ian Sparkes wrote:Nice work!I'm not sure if it is just your picture, but they look over-driven to me. It's perhaps just the exposure - I guess D1 is a Zener to provide some stability on the drive to the filaments, maybe you need to drop the voltage on that. The Zener is a pretty wasteful way of stabilising the voltage - you're going to need to provide for about an amp at full blast (42 segments at around 20mA = .84A), and to dump the excess over the life of the clock amounts to a lot of energy.That's also a fairly hard set up you have there to find a nice case for, with the big dev board standing way up. Also for kits, you're going to want to put those drivers in sockets and they will also stand proud and too close behind the tubes to make an attractive casing easy.Here's my take on it - feel free to nab a few ideas there.

Re: [neonixie-l] Re: Any interest in IV-9 numitron clock kit?
Nice work! I'm not sure if it is just your picture, but they look over-driven to me. It's perhaps just the exposure - I guess D1 is a Zener to provide some stability on the drive to the filaments, maybe you need to drop the voltage on that. The Zener is a pretty wasteful way of stabilising the voltage - you're going to need to provide for about an amp at full blast (42 segments at around 20mA = .84A), and to dump the excess over the life of the clock amounts to a lot of energy. That's also a fairly hard set up you have there to find a nice case for, with the big dev board standing way up. Also for kits, you're going to want to put those drivers in sockets and they will also stand proud and too close behind the tubes to make an attractive casing easy. Here's my take on it - feel free to nab a few ideas there. (These are not for sale at the moment - stock trouble). https://www.nixieclock.biz/StoreNumitron-6Digit.html https://www.nixieclock.biz/StoreNumitron-4Digit.html BTW, when I was still delivering these, I would usually deliver them with the USB connector and the NeoPixels already soldered and tested.

Re: [neonixie-l] Re: Any interest in IV-9 numitron clock kit?
Hi Everybody, I'm happy to say the first prototype PCB has arrived and has been assembled! Some pictures here: http://www.neonixie.com/IV-9-6D-RR/ Some details.. - I purposefully picked all through hole parts as this will be in full kit form. - I ended up choosing the TI TPIC6C596N driver. It does everything I need and is pin compatibility with PN '595N and possibly a few others. I've been testing software that keeps the unlit segments 'warm' by PWM'ing them to just barely invisible.. not so sure if this is going to make a big lifespan difference. These are being driven by a 74AHCT125 for the logic level shift (3.3v to 5v). - The controller is a ESP32 original dev board from Espressif, the same one I use for my previous nixie clock. This gives me a known good working part number and software carry over from my prior nixie clock. Most of the features of that clock will carry over directly to this one, including the BH1750 lux module and AHT20 temperature/humidity sensor. - Input is 5v via a common DC barrel jack. I did order a few USB-C input jacks, even found a through-hole one. I decided against using it in a kit due to the more delicate soldering required, as well as the unknown quality of all the USB cables and power supplies I generally run into. This runs the IV-9s directly and optionally through a diode to run them at a slightly lower voltage of ~4.2v if desired. I am ordering more parts and should have a few beta boards out before the holidays. Hopefully production kits will be ready sometime in January! Thanks to everyone who provided advice and feedback!

Re: [neonixie-l] Re: Any interest in IV-9 numitron clock kit?
Cool project! I don't need any currently, but thank you for the offer. I am swamped with sorting the more recent auction junk and parts, trying to clean up the shed so I can safely use the lathe and milling machine. Stacked up the 6 or 7 pieces of old test gear recently acquired that use nixie for the displays. Big old Sangamo mica transmitter caps, huge HV high power resistors and rectifiers, RCA SCRs, all kinds of fun things! On Tue, Nov 22, 2022 at 8:24 PM Michail Wilson wrote: > Well, yes.

RE: [neonixie-l] Re: Any interest in IV-9 numitron clock kit?
Well, yes. That is the TLC5916IN which is the DIP version.I use the SMT version. That price is robbery; however, if you need it, then you need it. If you only need a couple and need SMT, then I wouldn’t mind sending to you (as a member of this group). The great thing about this chip is you only need a single resistor for the chip instead of one per segment.

Re: [neonixie-l] Re: Any interest in IV-9 numitron clock kit?
Ian, Yes! I had that chip in my list of ones to test. Can't find any TLC5916 anywhere, BUT can find sporadic stock of TLC5917. The TLC5917 looks identical except it says it adds short protection detection? It also can run 3.3v, so saves a level shifter if running an ESP. Do you know if there is a cross reference to another pin compatible driver from another manufacturer? I try not to lock myself into one manufacturer if possible, especially these days. My other option was high power '595 shift registers like the TPIC6B595. Benefit being it may be a more 'universal' part in case I need more in the future. I agree the ESP32 is a bit overkill.. but it worked so well in my prior clock I'll likely use it again. Plus code reuse, I should need minimal changes and only have to maintain essentially one piece of code for multiple clocks.

Re: [neonixie-l] Re: Any interest in IV-9 numitron clock kit?
Ian, My research brought me to that same exact driver from TI! TLC5916... but yes, no stock anywhere. BUT there is spotty stock of TLC5917 here and there. Seems to be the same but has short detection? Runs at 3.3v too.. so I save the logic shifter. My other option is a regular 595, or actually the high power versions, something like TPIC6B595. I'm liking the TI TLC5916/TLC5917 led driver... do you know if there is a pin to pin equivalent from another manufacturer? I'm really trying not to lock myself into one particular manufacturer, especially these days. The ESP32 has been working really well for me on my previous clock project. I agree it is overkill.. but I spent a good deal of time on the clock code and I'd like to continue to use it.

Re: [neonixie-l] Re: Any interest in IV-9 numitron clock kit?
Constant-current is an excellent approach for incandescent devices because it eliminates the inrush current-surge that shortens the life of the filament. Recall that a cold filament has lower resistance versus when hot; current-limiting also allows the filament to heat-up slower, which reduces mechanical shock. I always hated it when I walked into a dark room, flipped-on the light switch, and POOF went the light bulb.

Re: [neonixie-l] Re: Any interest in IV-9 numitron clock kit?
You really should try to make the drivers constant current drivers: I used to do this with TI parts, but they've been out of stock for over a year. The TLC5916N drivers are shift registers with constant current drivers attached - great for this sort of thing. The Numitron clocks I made are also NTP/WiFi enabled and based on an ESP8266, with linear digit dimming and a whole bunch of other things (motion sensor, NeoPixel backlights etc). The ESP32 is a great platform. Absolutely love working with it, but it's a bit overkill for this.
