Talk:1796: Focus Knob

Maybe Randall is implying that he has issues with keeping the big picture in mind while doing detail work and gets lost in the details of implementation and vice versa. This means that for him the knob is more of an on/off or selection switch. Pulse Width Modulation would then allow him to use this on/off switch more like the knob in the picture shown. (... or whoevers voice Randall is speaking in as many people probably have issues with this, myself included.) I wonder if he obsessed over how to implement this comic: 1. As an on/off switch? 2. As a knob with limited none-usefull settings with "ideal" labeled between the actual settings available? 3. Like this, for simplicity, keeping the big picture in mind and not obsessing over the details of how it may under some circumstances be viewed? --162.158.91.95 10:19, 8 February 2017 (UTC)cdm

If the knob only has discrete positions, none of which lies within the balanced region, he could use PWM to simulate that position. Let's say the focus variable goes from 0 to 10, the knob can only stay on integer values and the "sweet spot" is around 7,38. He can make a cycle that rests on 7 62% of the time and at 8 38% of the time, and repeat this cycle with a high enough frequency so that his mind wouldn't know the difference from actually being at 7.38 focus level.
