Clock in a bottle

CodeDalek

This is a unique clock that uses a Russian Numatron tube. The tube is a seven segment display that uses incandescent filaments for each of the segments. This technology is from the same period that the now popular Nixie tubes, however it operates at low voltage and glows with a yellow color. The kit contains incandescent Edison base tube as the display case for this single digit clock, It is a bulb within a bulb. A single digit clock flashes out the time one digit at a time. There are four bulbs that indicate which digit is currently displayed (Tens of Hours, Hours, Tens of Minutes and Minutes).

I'm presently building the kit. It looks as though the battery holder must mount to the bottom of the PC board? What's jp1 for? Is the PIC pre-programmed?

Yes The battery holder mounts on the bottom. JP1 allows the decimal point to be wired up to the MCU. I did not want to test the in-circuit programming with the decimal connected. The code currently does not drive the DP line.

I uploaded the code and hex files when submitting the project. I don't know how you access the files that are submitted with a project including the Source and PCB files.
