JAN 8421 Nixie Clock on old circuit board

Nixie Clock

I found this clock by accident and I really wanted to feature it on this site.  There are a lot of home brew nixie clocks but most involve re-engineering every aspect of the electronics.  Matthew took a different approach.  He found an old breadboard and located matching JAN 8421 (nearly identical to a B-5092) nixie tubes.  The board had an existing edge connector to Matthew designed a clock driver to fit on the end.  Be sure to check out his site for more information about the power supply and the timing circuitry.
