Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

  Grogster said   ... but it was on the outer edge of the PCB, and when they slice them up in the factory, that cut off the connection to the ground-plane.


not unheard of here either. I did a weird half-moon shaped PCB to go in the clock of a Harley FDX. I had it roughly routed in the gerbers as I planned to finish by hand on the belt sander as each clock housing seems to be unique. Same thing here - assembled and some of the segments of the LEDs were out. A trace was right on the edge and *I* had removed it as I shaped the outer curve of the PCB despite being oh-so careful.



Meh. It happens. That's what enameled copper wire is for     Got there in the end. ... a few bikes belting around with 'mites in the mix.

Glad you found it.

Me, I am too much of a perfectionist in that department, so have corrected the ORIGINAL PCB, so that the grouhd is much better routed and most-definetly now in place, and am having the boards made again.

Enamelled wire etc to confirm the error, but then I can't bring myself to leave them like that, so a new batch of boards it is.  

Your display looks awesome, BTW!

can't fault that.

If I were to get any more boards done there are a number of screw-ups I would correct but the run is tiny so the original 10 boards I had done (as a min order) will last forever and probably go in the skip with the rest of the workshop contents when I croak.

Until then, NO PRISONERS!!!!!
