Not sure if you meant my wristwatch, or Westdave's clock..... I have design files for gEDA PCB, etc, but I dont recommend this design to anyone for a wristwatch. My HV power supply overheats after 15-20 seconds of continuous usage (transformer saturation). The original watch shown in my photo no longer works (transformer overheated, I think) , though the original prototype board is still working fine. Believe it or not, the original prototype is powered by a "worn-out" cellphone battery, that was charged 5 years ago, and it's still keeping decent time and running from that original charge. Every few weeks I confirm it's still running OK and the display his decent brightness.
The footprint was pretty easy to make; I used a digital caliper to measure the pins relative to 1 location. It takes a few minutes to gently wiggle the display into the PCB. The code is written in verilog, and compiled onto an FPGA. Unless you have FPGA experience and good soldering skills with SMT devices, this is not a project I would recommend. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
