Green+Red is not recommended as the colour mixing is poor. | + | * You can choose either Blue+Green LEDs (recommended) or Blue+Red. You could interchange some Green for Red.

| - | * Slider height: I specified 15mm shaft sliders, you could change these for 10mm. 15mm will protrude 13mm out of the case, which might be a bit long. 10mm will only protrude 8mm, so they would be less likely to break off and will probably be a bit more sturdy. TK. suggests 1k should work, the others are too high in resistance to get good jitter-free values (10k sliders with the shorter shaft don't appear to be available). | + | * Slider height: I specified 15mm shaft sliders, you could change these for 10mm. 15mm will protrude 13mm out of the case, which might be a bit long. 10mm will only protrude 8mm, so they would be less likely to break off and will probably be a bit more sturdy.
