Jürgen just sent in a new clock that he will soon be selling as a kit on his website.  It is an IV-12 based vacuum fluorescent tube clock with a clean looking sandwich style acrylic enclosure.  The kit will also include a power supply, lead forming tool and gloves.  The completed enclosure should be 196mm X 65mm X 23mm.

This is a neat looking clock. I like the acrylic tube plate. I would like to see nicer fasteners used...maybe SS Allen head sockets? Quality fasteners make a BIG difference I like this tube...really pretty and still cheap! Probably not for long though if it's use becomes popular.

Hello Michael,
the fastening in the final version of the kit is made with flat allen head screws, of course. As I have taken these pictures from the very first prototype I had only such screws with a lenght of 12 mm on stock and when you have a total thickness of 22.5 mm of the enclosure you'll get problems when try to screw with 2 x 12 mm ;-)
