![]() The overall circuit is powered through an off-the-shelf low-voltage AC-to-DC adapter. Not to cutoff entire power to the overall circuit, but just to cutoff the high voltage to the Nixie Tubes when the user wishes to turn off the Nixie light when going to sleep at night. There will be a main latching push button power switch. Pushing the encoder puts the system into "set mode", rotate to set hour, push again, rotate to set minute, push again, rotate to set second, push again, and back to normal ticking operation. The setting of the clock's time will be done via a rotary encoder. The red, green, and blue controls of each LED will be controllable through 3 latching push button switches so a combination of colors can be achieved. It will be a 6-digit 12-hour clock (H1 H0 : M1 M0 : S1 S0)īeneath each Nixie Tube will rest a small RGB LED to add additional color if the user wishes. Lastly, to reduce the size of the Nixie Clock's PCB by placing the HV PCB behind the main circuit board to keep out of view in the final clock box. Also to limit (as much as possible) the presence of high voltage and noise generated by the HV generator on the actual Nixie PCB. ![]() To give the overall project a more modular and flexible design in case I want to use the high voltage supply for another application. ![]() The high voltage supply's circuitry will be its own standalone circuit/PCB. The clock's logic would be powered via a simple microcontroller (PIC16, PIC18, etc.) not with the overkill of a single-board computer (Raspberry Pi, etc.). After researching and reading up on the impractical but beautiful technology, I wanted to build my own Nixie Tube Clock.Īfter observing features implemented on other Nixie Clock builds I found online, I decided on a few requirements for the 1st version of this project: I then found electronics websites and youtube channels explaining the circuit design required for driving Nixie Tubes that became critical for designing my own: EEVBLOG, Fran Blanche, Dalibor Farny, and Threeneuron. I also found many Nixie Tube clocks (the most common application nowadays) for sale built by hobbyists. A little searching proved old stock from Eastern Europe and Russia were available to purchase. Even though they require a ridiculous DC voltage level to operate, they truly are beautiful. ![]() Alas, at the time, i was putting more importance on having Bluetooth compatibility/build in pre-amp, over the quality of other things, which is really more important.I can't remember my first exposure to Nixie Tubes but I became fascinated with the old technology immediately upon learning of them. Also, would like a new turntable, but I think improving the speaker situation is more pressing at the moment and replacing the turntable itself can wait another year (which would let me get more use out of this turntable i still JUST bought like four months ago, sigh). This year, probably around Christmas- I want to get a tube amp and a decent set of bookshelf speakers so i can get true analog sound and really take advantage of the vinyl sound. I'm getting by (and completely sucked into the hobby, bought lots of records, etc) but wish I spent a little more on the turntable for other brands that are much more speed stable/have less WOW and flutter, and a have gotten whole better analogue speaker-set up. Then upgraded to an entry level manual turntable, which is 100X better than the Victrola, and a nice Klipsch Bluetooth speaker box to go with it (which I thought was good idea at the time, and it is a good Bluetooth speaker box, not really aware of the sound limitations of Bluetooth and how it really just kills the range of sound you can get from vinyl. Unfortunately, I'm learning about the hobby as I go and made a lot of poor initial choices- first got a $50 Victrola suitcase "record player"- didn't expect greatness, but also didn't expect that it would just skip incessantly, and just generally fail to play a record competently and that is normal for those players. I fell into the vinyl record wormhole this past Christmas. ![]()
