Mark,
Interesting info, thank you!
What is your voltage and filament current?

I usually drive the filaments non-multiplexed from 74HC595 shift registers
(technically slightly out of spec, but have always worked fine), and use
the output enable line to PWM all of the displays at once for brightness
control. I run a separate PWM on each filament that's off, keeping it
I’m interested. Have 10 DT-104’s I’ve been saving for a long time. Sent from my iPhoneOn Nov 18, 2022, at 1:43 AM, neonixie-l@googlegroups.com wrote:

Thanks everyone for your interest. PM me please if anyone else is
interested, either in beta testing a board or buying one when it's
released, I'll keep you informed.

Ian,
Yes! I had that chip in my list of ones to test. Can't find any TLC5916
anywhere, BUT can find sporadic stock of TLC5917. The TLC5917 looks
identical except it says it adds short protection detection? It also can
run 3.3v, so saves a level shifter if running an ESP.
Do you know if there
Ian,
My research brought me to that same exact driver from TI! TLC5916... but
yes, no stock anywhere. BUT there is spotty stock of TLC5917 here and
there. Seems to be the same but has short detection? Runs at 3.3v too.. so
I save the logic shifter.
My other option is a regular 595, or actually
