    it's kinda dogshit but for this application it (cmos version) would be good enough. or better than that, there are dedicated pwm signal generators. i meant this thing in terms of complexity needed

    It was a good insight into how the lightbulb dimming tech of the 80s/90s worked. Also why the dimmer switches back then were so dangerous with the capacitor likely just a few mm's away from the light switch which might not have been properly wired because UK homes back then didn't run a neutral back from the switch, but daisy-chained the switch and the bulb together and then ran the neutral back from the bulb
