The two-wire chopstick sanitiser
Added 2021-03-16 23:01:16 +0000 UTCHaving already reverse engineered the four-wire version of this, I thought it would be fun to look at the simpler two wire version.
I love the visual effect of the tubes in these, but they probably are quite electrically noisy. (As well as being audibly noisy.)

I pondered that, but wonder if the continuous supply from the cap dropper would keep it latched.

2021-03-17 15:53:22 +0000 UTCI was thinking that looked like a relay position as well.

2021-03-17 14:03:56 +0000 UTCThe 2W10 location is strange, the only thing I can find on this is for a half wave rectifier, it may be an option instead of the discrete diodes but the layout looks like a relay position. Maybe the labels don't line up properly and the board has options for both versions?

2021-03-17 11:33:44 +0000 UTCI get the feeling it's not radio friendly.

2021-03-17 05:56:02 +0000 UTCThank you for exploring into the 120V side of things, Clive! These are interesting, but I think they would not like my radios. LOL

2021-03-17 00:49:05 +0000 UTCI'll say! from what I can see, it would dump an exactly equal spike energy into the mains as it does into the transformer. 220nf out from the SCR in both directions! Nasty!!! Of course, I have one on order!!!

2021-03-16 23:42:58 +0000 UTCGot one of them yesterday. Changed the mains wires straight away - they were crushed in a few places. Bloody noisy thing but does seem to produce a fair amount of ozone.

2021-03-16 23:29:37 +0000 UTCI thought it last time and I'll say it this time. These would make great SFX for amateur horror films.

2021-03-16 23:22:54 +0000 UTCIf you can’t hear it, how do you know it’s working 👍 Trying to answer my own question here, at 1.3 W, would 100 of these be more effective than 1 100x larger❓ yes right because we’re talking the surface area interface of the tube to create the corona These explainers have made me somuch more confident tackling small household issues❤️ thanks always BC🖖
