I had a similar problem, the reason was there were some cold welding spots and I had to redo them. Check that both your weldings for the missing lines in the Nixie tube are properly connected as well as your L connectors. Use a multi tool to check the connections.

EDIT; ALSO - if ou EVER need help making a PCB for any of your projects, i will help you make a PCB ALL FOR FREE ! you would get the PCB's in batches of 5 or 10 and would only need to pay for the cost of the PCB's from the manufacturer that i use (elecrow.com) and then sit back and wait for your PCB'S to arrive ! or if you need me to solder SMD parts, id ship the PCB's to me, solder the parts, then ship it to you :)

Good day to you Anto ! really wanted to say thank so very very much for the reply, i am truly grateful !!! My skills are really rudimentary for Arduino but if tutorials like yours are clearly written, have the FULL code listed and/or downloadable, i can follow instructions to the letter and get by, i am really trying to understand the arduino code but its really difficult for me at present (under a LOT of hourly pain killers..) So i must congratulate you on the b-e-a-utifully written tutorials youve made that go to inspite and help folks like me, i make it a point to always thank people like you who have the knowledge and ability to write such awesome pages on the internet !!! Also as for the commercial product, i have some of those and sad to say they are way too big for my use in my project. My project box is 60x36x26mm so its a tiny space to incorporate this tiny voltmeter - also I LOVE SMD SOLDERING - if i have a PCB made up, i would always use SMD Components, i can solder down to 0402 with the help of a magnifier, but can solder 0603 parts without a magnifier. The Atmel microcontroller i'd end up using, like a dead-bug way, would be the SMD Atmega328P-AU i also dont have that tiny OLED yet either, its in the post, so when it arrives i will try your suggesstions and probably show you my progress too if you'd like :) But, once again, i cannot thank you enough, there are times when words just arnt enough !!! Keep up the most-excellent & inspiring tutorials !!

In the last update of the project, the target project is already changed. C19 is right now around the circuit diagram and the Board. Tantalum capacitors have regard to I not experience. In the data sheet of the ICL7660, no note is that necessarily are tantalum of electrolytic capacitors to use. I have soldered tentatively times 22uF instead 47uF and get it - 4,98V at pin 4 of the OPV. Dieter Aschmann

For some days, some digits only partially light up. What can be the cause and someone has a solution for it? I'm grateful for any support. Walter
