Missing digits are usually due to soldering problems between the VFD chip and the tube. Post clear photos of the solder side of both boards and we will check them.
also when i was done soldering it i noticed i was missing some parts, the parts i'm missing are:
12mm 3V lithium coin cell
Nylon 4-40 Hex nut X 10
Nylon 4-40 1/2" machine screw X 8
icsp 6 pin header, 0.1"x0.1" spacin
Check the packaging, sometimes these small parts get lost in the packing materials.
If you are still missing parts, contact email@example.com
with a link to this thread for replacements.
