A rather unique opportunity to explore a prototype of a product that did make it to market, but seems to be hard to find.
I've got to admit that I felt a bit uncomfortable making this video. I get the feeling that the inventor put a lot of time and money into designing and trying to get funding to bring this product to market.
A note came with this device suggesting it used the antenna disabling technique.
There's a broad-spectrum patent that seems to be associated with this product, but it doesn't specifically mention the antennae effect. Just that the antennae will bridge the gap between the electrodes. It seems to suggest the main difference from a traditional insect zapper is the horizontal plates and darkness more suited to crawling bugs.
It also suggests a timing of 30 seconds of zapping every 20 minutes.
Here's a link to the patent, which expired in 2002:-

The engineering of the case is complex and stylish, but would have made the unit quite expensive to manufacture in this form. If the product had taken off and been a huge commercial success, the inevitable clone products would probably have used a much simpler two part case that plugged together with a single base plate contact pin and safety switch. The circuitry these days would be the inevitable 8-pin microcontroller driving a small CCFL style transformer and multiplier arrangement.
I'd like to know the history of this unit and how much work and experimentation was involved in testing the concept and designing the unit. The resin moulded case is immaculate and would have been expensive and time consuming to make as it predates 3D printing.
Here's a link to an Australian science/art museum page showing one of the commercial products with the simpler case and latch at the front:-

This also keeps the channel independent of YouTube's advertising algorithms allowing it to be a bit more dangerous and naughty.

Many cockroaches 🪳 died to bring you these plans 😅 Death Star 😂
Yep: Clive
There was a product marketed around 1991 in Australia called the Magic Mushroom that looked similar. It was fantastic & cleared up an infestation. Only sold in TV adverts & we could never find another. I keep searching every couple of years for one, search brought me here… I have tried a couple along the way, none as good as the mushroom was
No. Just… no.
i know this is an old video, but I'm a little confused by this – if cockroaches eject egg sacs upon death, surely this would just mean that they go and die elsewhere, and still eject the egg sac? and said eggs would be close enough that they would eventually make their way back to the area?
This is so odd. The technology is like from 1985. As is the use of a CRT flyback transformer.
yeaa
Ooooh its a flyback
I like it
I found cockroach, i will run naked outside burning the house and go to canada, never to be seen again.
Was not expecting a bad dragon refference, kinda shocked me lol
Was not expecting to hear Bad Dragon
I've seen cockroaches go crazy after chemical treatments. They seem to be able to detect heat or carbon dioxide.
I breed Dubia cockroaches to feed to my pet lizards. The first time I saw one of the egg sacks, it was kinda freaky!
Looks kinda like vacuum furnace door.
I think if you have cockroaches there are bigger issues than that thing can solve. Better off dousing the whole area in gas and burning em out
I believe putting the primary windings around the secondary is to create higher voltage with more amperage so as to do the damage to the antenna and not explode the whole insect.
That transformer looks like the flyback transformers I used to see on old tube television sets.
