Looks WAY overdriven!!! Don't expect it to last too long at that current...

A picture of one of my IN-18s plugged into the first PCB I have ever
designed and had made (KiCAD and OSH park). It is a breadboard
adaptor! It is being driven from an arduino using a K155ID1. Someone
(I don't remember who) pointed out that you can use a K155ID1 to drive
LEDs as a good way to test things out first. No sign of the infamous
blue dot on any of the digits. I'm very happy, though I don't plan on
using the K155ID1s in the final clock, I will use one of the supertex
chips - I have some HV5522s coming, so that is the next step!
Many thanks to everyone on this group - lots of useful input and
advice, though I have a long way to go yet!

Hi,
Does anyone have any suggestions about how to mount IN-18 tubes? It
looks like they are intended to be socketed and I see some
sockets/pins on ebay. I would like to underlight them too, if that
makes a difference.
By the way, does anyone have CAD files for the physical pin layout?
e.g DXF files, and/or KiCAD footprints?
Thanks - Paul
