has an excellent service for small orders of small boards. So if no one on the forum has a spare to sell you, that's one option. I've used the service several times while revising the Adafruit design.
In fact, if you're interested in making an Ice Tube Clock from scratch, it might be worth checking out my hardware revision (project summary
and Adafruit thread
). The documentation is pretty good, and I do answer questions through email or, preferably, this forum. If you're interested, I might even have a spare board and case parts somewhere...
