Just finished building the Bulbdial clock, and everything checked out perfectly until literally the last two LEDs. Using the "Adjust" mode, all of the blue LEDs work correctly, and all of the green LEDs work correctly. When checking the red LEDs, however, the last two (the ones at the 4 & 5 o'clock position - which should project 10 & 11 o'clock) do not light. Instead a combination of blue and red LEDs light. When the 4 o'clock position red LED should be lit, five red LEDs (at the 11, 12, 3, 7 and 8 o'clock positions) and five blue LEDs (at position 26, 27, 28, 29 & 30 - when starting with the topmost LED as 1 and counting clockwise) are lit. When the 5 o'clock position red LED should be lit, five red LEDs (at the 1, 2, 6, 9 & 10 o'clock positions) and five blue LEDs (at postions 5, 10, 15, 20 & 25 - when starting with the topmost LED as 1 and counting clockwise) are lit.
I've visually inspected the boards and all of the solder joints look good. I've checked the orientation of the two problem red LEDs, and they appear the same as the 10 red LEDs that work correctly (i.e. flat end faces same way). Any hints on how I can troubleshoot this?
