Actually, that code works well! I had a typo on a pin config. Seems to work well! Very pleased. I hope you find that snipped of code useful. > On 22 Dec 2023, at 17:58, Max DN wrote: > > > Jörg, > > This is the code that I am using with DAC 4822 (similar to 4922 but with > internal ref.).

Thanks for your prompt reply David. I have already printed my board for a Teensy 3.6. I have no issues soldering tiny smd components assuming that I can get an LTC22632! I may design a small PCB to super-impose the Teensy 4.1 over the existing footprint and layout. In doing so, I could add the

Hello, what transformer do you use for the power supply? I'm about to build that clock and I was thinking of winding my own transformer but if an off the shelf version can be used that's easier. Thank you.  Original message From: jörg Date: 04/03/2023 12:14 (GMT+00:00) To:

Re: [neonixie-l] 14-digit nixie calculator project with clock function

Thanks for your reply. That is an excellent transformer indeed. I have made a custom version of it, slightly smaller, it goes up to 100mA (gets a little warm but not much) and can comfortably take 70mA too. It can comfortably take 6 RZ568M nixies made by Dalibor. I am now looking at the

Beautiful, works like a dream! I’ll go on and play around with GPS and Motion sensor features. If you don’t mind, I’ll ping you again for anything quick but I’ll try to understand the code myself first. You did save me a couple of nights going through the code though :) Thanks so much. Max

Re: [neonixie-l] Nixie Clock - Direct Drive HV5530

Hi Jonathan, I have built this clock and works well. I have however decided to go for a 4 digits version instead of 6. I can manually set the time, no issues. But when I go through the parameters menu, I can see the menu number but not the parameter numbers of each menu as the code is

Re: [neonixie-l] Re: 14-digit nixie calculator project with clock function

Just curious, what is the power of the high voltage power supply? I suppose you need 35mA but really at least 60mA to avoid any heating issues?  Original message From: Adrian Godwin Date: 03/10/2022 10:46 (GMT+00:00) To: neonixie-l@googlegroups.com Subject: Re: [neonixie-l]

Re: [neonixie-l] HVPS in parallel

Hi Richard, David, I'm using my design of the NCH8200HV, it's mostly its replica as I wanted to embed the design in my board and I'm not bothered about the 'not invented here' syndrome as I'm not selling commercially. 'Sinking' the HVPS into a pcb cutout is a good idea though, I had seen that

Re: [neonixie-l] Re: HVPS in parallel

I thought so too, but I’m thinking that the regulated HV pulses from one power supply may impact the feedback resistor(s) on the other power supply, potentially messing up the feedback loops on both sides. I could add a HV diode such that current doesn’t flow from one power supply into the top

Re: [neonixie-l] Re: Nixie Clock - Direct Drive HV5530

Great. I found a nice page that confirms the sequence of CLK/Data, I think it's in line with my understanding of your suggestions.  http://reboots.g-cipher.net/time/So, the code for a serial to parallel convertershould be easy to implement.Yes, I'm aware that some people use the hv5530 at 5V

RE: [neonixie-l] Re: Nixie Clock - Direct Drive HV5530

Thanks.In terms of nixie brightness, is there any advantage in using serial to parallel converter+shift register vs multiplexing using high voltage transistors on anodes and cathodes of the nixies? Other than saving component and uC pins, of course.  Original message From: Bill

Re: [neonixie-l] Calculating Anode Resistor Values

Hello, the correct resistor is calculated as 170V minus maintaining voltage (check the datasheet of the nixie, usually 140v or so) / current. So, for a nixie that needs 2mA you would use a resistor of: (170v - 140v) / 0.002 = 15k ohm. I hope that helps. Max > On 6 Jul 2022, at 23:54, Mac
