Really clever "memory" circuit in air "freshener"
Added 2021-09-15 22:00:33 +0000 UTCThis unit can actually tell if the cartridge has been unplugged - even when it's not powered.

And the way it does it with discrete components is VERY clever.

I donβt understand the point of having memory though?
2021-09-21 05:23:11 +0000 UTCI'm wondering if it's a low leakage capacitor or just evolved technology.
