Hi Tony,

I'm pretty sure the LEDs were lit up.
I'll dismantle it and check the points you mentioned.
Thanks,

Hi Tony, I wondered if you could help with a problem I'm having with my thermometer. I have mine on a timer, so it switches off during the night and while I'm at work. This morning when it turned on, the second last (celcius) nixie was the only one lit up. It also wasn't lit correctly, like all of t...

Hi Tony, I just built my third one of these (this one's mine). I found a small error in the updated instructions. R29 isn't mentioned which is needed to light up D17. Where the installation of the 1K2 resistors is shown, the photo shows six resistors circled but the text only mentions five. If it wa...

Something that might make our sanding easier. Get some more M4 bolts and nuts (or use the original bolts and add standard nuts. Sandwich the thick rings together in one group. Put the PCB spacer in the middle. This makes it a lot stronger and you can sand all of the layers at once. Repeat with the t...

Hi Tony,

Never mind. I figured out what to do.
A small length of black heat shrink tube over the IR LED to direct the light straight up instead of bouncing around inside the case.
It looks great.
Excellent kit, Tony!

Hi Tony.

One more little issue.
When I assemble everything, the nixies just cycle through modes continuously.
The IR signal is being reflected inside the case. Waving my hand over it doesn't do anything at all.
Any clues?

Thanks, Dale

Hi Tony, I don't know what happened, but it's working. It could be that my meter just wouldn't measure across R28 correctly. I did have another go at cleaning up some solder connections. After a good clean with quality contact cleaner (highly recommended), there were a couple of spots that looked a ...

Hi Tony, I checked the fuse with my other meter and it's okay. I also removed D17 and checked it off the board. It's also okay. It must've been C5 that was drawing power from the meter. The only temp sensor I can get nearby is a DHT22. It's bigger, but it should work. I still don't know why I'm not ...

Hi Tony, I wondered if you could help me with some problems I'm having with my build? In a nutshell, I can't get the first stage power-up test to work. No LEDs light up and I have no current across R28. To begin with, I think I've damaged IC4. I didn't scroll down the instruction page far enough and...
