Hi is it possible to run just four tubes instead of six from the classic board customer wants a keepsake box made into a clock there is just enough room for the PCB and careful wiring to four ni16 tubes thanks in advance Mick
Yes! Ian just recently added some new code to the repositories for 4-digit clocks. I haven't used it yet, but it is altered to allow configuration with just the display of 4 tubes. The latest version can be found on bitbucket
It's in the folder "ardunixFade9_4_digit"
Indeed, the Classic now has support for 4 digits, it was a request that came up over and over again. The PCB also now has the two freed up pins brought out to the "front panel" header so you can use them for other things.
