On the Optical Phasor board (modeled after the Mutron II / biphase), the light dependent resistor cells must be shielded from ambient light to function properly.
On the current version I built, I used an old vanilla extract cap hot-melt glued to the pcb. This actually works pretty well, but it's no fun having to chug a bottle of vanilla extract every time you want to make a board :P
Ideally there would be a little 3D printed cap that covers the LDR ring and LED. This could snap into little holes strategically placed in the pcb, or just get hot-glued down (I like the snap-in holes idea though).
