  • Be careful to orient your stacks of LEDs correctly. Read the silkscreen carefully as it is correct. The graphic in the pdf instructions is wrong/outdated. I know because I mistakenly used the orientation of the “special led” to the crystal in the photo as a guide and got it backwards. No big deal, I learned how to desolder with a desoldering pump along the way.

No public wish lists :(
