When doing a short run you don't need to sell them in places where people need support.
Are you in the Neonixie google group?
Selling them here and there only gets you experienced customers so minimal support needed.
I don't need GPS.
To tell you the truth, I only use Nixie clocks as regular clocks.
I really don't care for alarms, GPS, countdown timers, stopwatches and everything else.
I love Nixie clocks for how they look, not for what they can do.
That's why I'm perfectly happy with the Chinese board I posted above, it's just still too large for some of my projects.
My only intention when I started this thread was to get a tiny board that can do all the basic functions giving me flexibility with my case designs.
