code using pins on current flying spaghetti monster PCB version for current LED bus configuration. One could use pin 7 as an ADC input for flashing speed via a pot, but this would shift the output function to pin 5. Code changes would be needed for this.
50mm x 100mm board outline done in pcb-rnd to set constraints. The layout was then exported to FidoCadJ format. Freeform design of outline layer, silk screen and tracks on top and bottom copper done within FidoCadJ. At this point the design was exported back to gEDA pcb-rnd/PCB format for final touches and export to gerber for manufacture.
