| Mar 1, 2018 at 20:18 | comment | added | KlaymenDK | Thanks for this neat design! A shame that making changes requires balancing all three components, but that's just the nature of the thing (so to be clear, no blame to you). | |

| Mar 1, 2018 at 16:44 | comment | added | Jim | @Spehro 102k total series resistance for the LED? Won't the LED light be imperceptible, rather than just dimmed like OP originally wanted? | |
| Mar 1, 2018 at 16:15 | comment | added | Russell Borogove | Mentioning the RC time constant formula and giving some indication of which way to change resistor values to make it smoother, dimmer, or brighter would make this a very helpful answer. | |
