Eight digit B7971 Clock

[Mitch]

Finished. No cut traces, no jumpers, and no bugs reported so far. It runs the same firmware as all of my word clocks, Nixie and LED.

Big and beautiful. Do you have any more pictures or documentation about the design?

Nice. I actually have eight of these tubes. Just saying.

Looks like you have a second board behind, with colon partially visible.

I hope you bought your tubes awhile back; the recent b7971 prices are crazy.

Thanks! Boards and programmed microcontrollers will be available from me, full kits elsewhere.

Documentation is at angryelectrons.co, in the downloads section. The assembly manual isn't finished yet. Operations manual is the same for all word clocks.

The board behind the clock is the six digit version. I don't have enough tubes to run both without decommissioning one of two other B7971 clocks that I have. I may just do that.

Looks really neat Mitch. I'm also a 7971 clock fan. I have a seven digit but not 8 yet!!! Are you going to sell some?
