Mr. Carlson's Lab? More like Mr. Carlson's EMPIRE! You have a very impressive collection of equipment and knowledge. Great videos and explanations. Thanks for sharing!

Nixies are cool. I have two instruments from the Heathkit company that use nixies. IM-1002 digital voltmeter, 3 and one half digit display. The half digit is acquired using an NE-2H lamp. The other is IB-1102 which is an eight digit frequency counter that measures from one Hertz to 120 MHz . They were purchased in kit form in approximately 1974. Both still function beautifully. All of the digits are still bright. 42 years and going strong. I did have to repair them a couple of times, but Heath's manuals are superb.

As always a big thumbs up. I just found you channel a month ago and I'm enjoying every minute. Thank you for what you do.

Great video. Thank you very much.

Back in the early 70s, before 7 segment LED displays became avaiable at affordable prices, I needed to build a 2 inch wide professional audio tape recorder display and encoder for editing and finding spots on the tape for overdubbing. I designed the high speed bearing tape encoder to retrofit at a spot of the tape path before going through the 24 track recording heads. I found a bunch of surplus nixie tubes and started to build my own display unit that had TTL logic and was driven from rotational pules from the encoder capstan. The nixie tubes required special TTL drivers (BCD to Decimal) 74141 from what I remember due to the high voltage on the anode. I think the 10 o/ps to the nixie cathodes were at TTL open collector level pulled to ground to turn on the appropriate digit with 4 inputs, which were internally decoded to go only from 0000 to 1001, the other values 1010 to 1111 were ignored inside the driver chip. The rest of my logic board to support the nixied BCD drivers was composed of TTL up/down counters, and some TTL schmitt trigger logic to clean and square up the pulses from the tape encoder.

Yes it was.I had my own custom electronic engineering company (basically me,myself and I) that went out and contracted anything I could repair or rebuild or design from scratch. There was a 24trk recording studio that had an Ampex 24trk recorder where the recording engineers had to find audible passages on the tape to cue up for overdubs. This was difficult sometimes in a large 2400ft reel of tape and one of them asked me if it was possible to come up with an electronic counter that they could record the footage on their master sheets and then refer to the spot on the tape during overdubs, rather than have to search for the audio track. The long searches cause lots of spill noise because as some may have heard, the sounds tapes make as they are shuttled back and forth to arrive at the right spot at speaker sound levels are not exactly pleasant if you have to do a lot of this. While the nixie tube display was relatively simple to engineer from scratch, the challenge was the addition of the tape footage counter measurement encoder capstan that had to be located on the deck, requiring drilling a hole in the deck at a specific place for the tape roller to contact the tape in an EXACT spot without affecting tape tension or introducing wow and flutter. This spot could not be determined ahead of time..so that was definitely a challenge for me. I had to convince the sound studio that if it didn't work the way it was supposed to work during the trial period, all there would be is a 3/8 hole in the deck that would be covered up with a chrome button, and only I would be out a lot of my time in designing it and installing it. It worked though and they were happy with the results as it made their jobs easier.

Paul, I can remember when digital instruments and calculators first came out. These used nixie tubes for their digital displays. (I guess I am dating myself) Anyway, nixie tubes have always had a definite "cool factor" in my opinion. A couple few years ago, I decided to design a nixie tube clock. After considering a couple different design approaches, I decided to make use of the very low cost Arduino UNO as a computing platform and design a 6-digit nixie display that would interface to the UNO. The circuit I designed utilizes a 12 volt AC input from a 1-amp Plug-in wall transformer. The use of low voltage AC power allowed an easy way to produce the needed high voltage for the nixie tubes (using a transformer), low voltage DC to run the UNO and other logic, and also provide a reliable 60 Hz time base for time keeping. I developed a PC board for all the circuitry, interface to the UNO, and a long 64 bit shift register which drives the individual elements in 6 nixie tubes plus decimal points in 3 of the nixies. I chose to use the IN-8-2 nixies (from Russia) as they are a nice size, have a decimal point, and feature distinctive "2" and "5". I also incorporated some additional features on the board - a power relay, speaker, potentiometer, temperature sensor, and several switch inputs. The UNO program I wrote runs the 6-digit display as a clock with added date and timing functions. I still have a couple of unused PC boards and would be happy to send you one at no cost. Might make for an interesting video. Let me know if you are interested.

Got a new box of 100 tubes somewhere. Going to have to dust them off and build one. Been looking for a good project for them. Great job on the explanation. Looking forward to the future episodes. Mike

Nice job on the detailed visual explanation. I know there are many places that sell Nixie tube desktop clocks but I want to build one from scratch using an old Analogic AN2534 Voltmeter unit. It has 4 Nixie tubes plus the high voltage source. Now that you showed me how to drive the Nixie tubes I will just disconnect the voltmeter driver section and feed in my own circuit (basically a Silicon Labs Busy Bee Microcontroller which will multiplex four CD4028 BCD drivers). In order to make this compact I'm using OnSemi's MSD42WT1G NPNs (in a surface mount SC-70 package) > 32 transistors should do it for a 4-digit 12hour clock.

Great video. I can't wait for the next one. I do have a question though, could you use a fet instead of a transistor?

Probably one for Patreon once I figure that out. I love indicators of all kinds. I can sit and watch old school VU meters move for hours. Nixies are one of my favorites and built a couple of clock kits. I would like to build the frequency counter as well but I am also fascinated by the magic eye tubes. I would love to see a standalone project (or one that could be added to the counter) that could be use for tuning or signal strength.

Great video. You can get creative and control a bunch of tubes with only 3 mcu pins (well 4 if you include ground) by using shift registers(which are easily daisy chained) to drive the BCD to decimal converters. You could use shift registers directly, but most only have 8 outputs, not 10 and if u want to use an mcu's hardware spi peripheral (as opposed to bit banging), most of those send data by the byte.

Great video Paul. I own a nixie tube clock that uses large Philips ZM1040 nixies. I've had it since 2003. I know that nixies eventually succumb to cathode poisoning. So far mine hasn't. I do rotate the tubes every 3 months. That probably has something to do with it.

well I just checked and no nixie fairy leaving any tubes under my pillow😭 can we build a cap tester next with that cats eye or a vu meter next😉 still so fun to watch. I don't even have big enough bread boards oh my!! awesome vid as usual
