Holographic fly repeller (FLICKER ALERT)
Added 2024-08-19 14:40:30 +0000 UTCAn unusual device bought from a local shop (Home Bargains in Edinburgh).
It has a spinning holographic blade that must appear as some sort of monster predator to flies.
The battery/USB switching circuitry is very novel and intriguing.

I am going to take it apart to have a looksee, as i'm kind of intrigued, I'll let you know what I find.

When I looked in the battery compartment, it has a single NiMh batter with the wires Hot glued onto the teminals! yet it is being charged at 5.1 volts. It also spins slowly compared to the one you showed. I will do a strip down tomorrow and tell you what I find- I may even do a video now I have a proper grown up Cell phone.

2024-08-23 05:28:00 +0000 UTCSo are they using the mosfet instead of a diode to minimize the voltage drop when battery is operating?

2024-08-22 10:21:08 +0000 UTCThey get used a lot here over Biltong displays... Though the ones ive seen aren't holographic thy are just a bunch of fishing line that spins. Think its more the movement that bothers the files

2024-08-20 15:00:20 +0000 UTCHow much did yours cost, Clive? They look to be around $30 to $40 here in Australia.

2024-08-20 01:24:21 +0000 UTCSome of the restaurants (bakeries) use them around here. Not sure if they work, but they keep the health inspectors happy. Looks identical to the one you featured.
