Price: $15 PCB Only / $65 Kit / Ice Tube clock

For the open-source fans, I have a neat little project for you.  It is an open soruce VFD clock called Ice Tube.  It is deisgned by and is based around the IV-18 VFD Tube.  I don't yet have one of these added to my VFD database yet, but basically it is an eight digit, 7-segment VFD display contained in a single glass envelope.  (It is projects like these that make me wish I had stayed an EE major...)
