After reading the dirk's slightly reanimated Monopixel thread, I got to thinking a little bit about an alternate design based on the LEDancer project. The main advantage of this approach is that there are a lot fewer solder joints, and the wiring is a lot simpler (not as easy to mess up).
The basic idea is to use the same LEDs as with the LEDancer, but use a pcb that holds only one LED, and use ribbon cable to connect them together. A sample design for that PCB is included, the board being approximately 0.35" x 0.475". The attached board is good for up to 12 LEDs in a 'string', with the proviso that every third board would have to be flipped upside-down about the horizontal axis (and the LED mounted on that board with pin 1 in the upper left corner).
Just a thought coming out of Covid-19 boredom, as it's likely too late in the year to do anything about it (and assuming that the LEDs used with the LEDancer are still available and not too expensive).
