Do you have a price target?

Count me in for 4.

Yes, it's based on the same core software as my other clocks. I provide the 
source, although not technically "open source".. it's on my website for anyone 
to look at.
There is a link to the source (and compiled binaries) under "ESP32 Firmware" at 
the following link. I've been on 0.92 BETA2 for a long time and I would 
consider it release quality. It's easy to recompile once you setup the correct 
Arduino environment with the proper libraries (listed at the beginning of the 
code).

Cool, so far I got two interested parties! ;)

Would it be open source?   If not,  would you make a basic open source program 
which can just talk to the tubes?
If open or partially, I would be interested in a few/several kits.

Folks,

I started working on a prototype IV-21 clock sometime last year. I got to the 
point of an advanced prototype, ready to move to a PCB.. but life got in the 
way.

I never really bothered with VFD displays much before, but now they are growing 
on me. This one is a good size for a more close up clock, it's been my "desk" 
clock for about a year now.

I can put this into production, I have plenty of tubes on hand, but would like 
to see if there is any interest from the group. If I can get 10-20 interested 
parties, I would pursue it to a production kit. My design is as follows:

Dual IV-21 tubes, as seen in the cardboard mockup.
ESP32 Xiao controller (NTP/wifi software based on my other clocks 
www.neonixie.com<http://www.neonixie.com>)
Onboard DC-DC step up controlled by the ESP
Modern max6921 serial VFD drivers

I like to see the date and/or UTC time along with local, so I like the dual 
tube idea.

Anyone interested?

Regards,
-Moses
