Inside a Rentokil / Victor electronic mousetrap.

This American designed mousetrap is sold in the UK under the Rentokill brand. It's interesting in that it uses a pair of metal pads to zap the mouse for a short time.
Here's a link to Shawn Wood's video showing the trap working:-
• The Newly Designed Vic...
Shawn lives on a farm and controls unwanted rodents out of necessity. He features lots of new and old mousetraps including 3D printed versions sent in by viewers.
He used to show them working in more detail, but fell victim to militant flagging on KZbin and now censors the demos.
I'd like to stress that I'm not into animal cruelty at all. I think mice and rats are quite cute and know that people often keep rats as pets. However, I'm also aware that there are some environments where you just don't want mice or rats breeding.
If you enjoy these videos you can help support the channel with a dollar for coffee, cookies and random gadgets for disassembly at:-
www.bigclive.com/coffee.htm
This also keeps the channel independent of KZbin's advertising algorithms allowing it to be a bit more dangerous and naughty.

Clive you're a man of culture. Mouse Trap Monday is my favorite mouse trap channel

[@strayiggytv]

I actually petitioned to have these electric traps installed at my work place. They're one of the cleanest most humane ways of pest control. Before my business invested in industrial electric traps they used a combination of glue traps and starve boxes. It's very hard to work next to a glue trap full of screaming mice or listened to them kill each other in a starve box. Gruesome stuff.

[@joinedupjon]

One of the ladies at work insisted that we use humane tipover traps (made of opaque plastic), but of course neither she or anyone else ever checked them... until alerted by a rather insistent aroma. The' humane' trap had caught a mouse which had then starved to death and gruesomely rotted inside. It would be more humane to just finish the mouse quickly. I think this design would be improved by having a sonic alert when it had killed something cos TBH no one's ever going to check it in a shared office space otherwise due to feelings of diluted responsibility. I guess if it's at home you realise you've got to check it.

@Maling Tørk I've used a spring loaded trap before and they are NOT always instant. I heard it snap and saw it caught the mouse by the snout, a few minutes later I stopped hearing the mouse.

[@ollieb9875]

Sorry but if you've literally got hundreds of mice IN THE HOUSE and they're shitting all over the food, eating the potatoes, chewing wires, poison is the way to go. Placed carefully within the building, cupboards, alcoves etc where no cats or children etc can get to that's it. Displaced mice caught in humane traps and transported elsewhere will be killed by any local colony, for example. Generally the poison is a blood thinner like warferen it stops clots and the mouse dies from brain hemorrhage after about 4 days of coming back each day to snack on the treaty product.

[@m0rthaus]

@@ollieb9875 Yeah and that's exactly what Gena and others are referring to - Warfarin is a decoagulant and when used in doses high enough to poison it makes it's victims extremely thirsty, so the mice (or rats) seek water outside the house, weakened, dying, and it's at that stage that predators like owls pick them off and eat them - subsequently also imbibing a dose of poison. Poisons generally available publicly cause long, slow, inhumane and ecologically impactful death - use something else if you have even the smallest bit of concern for other species. As an aside to your example. If you've got literally hundreds of mice in the house - you've let the problem get way too big before addressing it.

[@Fifury161]

I was going to buy the multi kill version of this, by the time I found something at a good price I no longer needed it! I guess the multi kill version has a very similar circuit - it removes the kill and resets, so the mechanics would be worth looking at. They also make a WiFi enabled version. I had started designing my own using the traditional mechanical trap coupled to an ESP, using the kinetic power of the trap to power up & send a signal that it had been activated. As you can tell I spent way too much time thinking about it and no longer had a problem to deal with!

[@seanet1310]

My guess for the strict cutoff for battery voltage under load is to get past humane rules or considerations. A low source voltage will be a low output voltage and if too low may result in pain but a very slow death of at all. Glad you didn't show footage Clive.

[@demef758]

What you have there is essentially a Kettering ignition coil circuit, Clive. That buzz you're hearing is transformer squeal, which cheap transformers like this will do unless given a dunk in some hot wax. Probing the waveforms with a scope probe on the primary (don't mess with the secondary!), would unlock the mystery of the circuit's operation. The discrete diodes protecting the CPU input are needed because the IC protection diodes are not very robust, only designed to snub out infrequent static zaps. They can't tolerate continues overvoltage stress like this. Discrete diodes can absorb a helluva lot more energy than the IC's input diodes can.

I use the victor rat traps (field rats- only a little bigger than mice- but too big for this trap, which I also have). Biggest downside is that they are very difficult to clean. Victor's newest rat trap was modified to make it easier to clean. Far more humane than a glue trap, more sure of a kill than a snap trap (so also more humane in that way) and no need for poisons, which will end up going higher in the food chain. There is also a Wifi alert version, but I've found the alert is pretty flaky.

[@rkirke1]

Great video! I agree that it's well designed electrically, but "humane" definitely needs the inverted commas! Some years ago I had a mouse problem at a rural property I was living at. I'd always prefer not to kill anything, but catching and releasing mice was literally illegal in that area. As an autistic physiology grad with an interest in electronics, of course I locked on and spent about a week researching & designing what would be necessary to make a truly humane electric mouse trap. I ended up pouring over piles of mouse cardiac physiology papers, ethics guidlines, running dozens of LTspice circuit simulations, the lot! TLDR; My conclusion was that it would be impossible to make one that wasn't either extremely elaborate, gruesome, or very dangerous to people. I never ended up finishing the prototypes because they were terrifying, but for the sake of morbid curiosity I'll outline below what I determined would have been needed. (CW: animal suffering, explaining how the trap in the video is horrific imo) Most rodents, including mice often exhibit "spontaneous cardioversion" - i.e their hearts will often automatically regain a normal rhythm after entering fibrillation (abnormal heart contractions = how electrical shocks usually kill). Electrical conductivity of the paws is usually very poor too, and they are highly sensitive to pain - many laboratory 'ethics' guidelines I read completely prohibited euthanizing lab animals with any kind of electrical shock to the paws. It's horrific to even say it, but I don't see how the above trap wouldn't just cause some mice to be paralyzed in pain for 20 seconds at a time until they suffocated or died of exhaustion. The only solution I could devise that might claim to be consistently humane was completely OTT. It had a cockroft-walton multiplier from mains, up to around 3kV to mitigate poor electrode to skin conductivity. Specially arranged spring electrodes were needed to ensure contact was with the head and sides of the mouse, not the paws, and the initial shock needed to be several joules to ensure instant loss of consciousness (big capacitor, big bang, potentially gruesome because of the power levels - the mechanism for ensuring loss of consciousness is by inducing a sudden temperature rise in the brain). It then needed a control system to apply a lower AC voltage for several minutes to ensure consciousness isn't regained and that cardioversion doesn't occur. This also had to ensure that enough current was being delivered, but not so much that it literally cooked the mouse and/or became a fire hazard. CONCLUSION: A proper electric trap needed to be elaborate, gruesome, *and* dangerous to people.. If you must, just use a traditional snap trap.

Disposable camera flashes are fun. Definitely enough to give an overly inquisitive human a nasty zing, but I'm guessing not enough to be lethal to a mouse?

Imagine you're looking for something because you really smell peanut butter, all of the sudden 4,000 VDC goes through your chest

'E's passed on! This mouse is no more! He has ceased to be! 'E's expired and gone to meet 'is maker! 'E's a stiff! Bereft of life, 'e rests in peace! 'Is metabolic processes are now 'istory! 'E's off the twig! 'E's kicked the bucket, 'e's shuffled off 'is mortal coil, run down the curtain and joined the bleedin' choir invisible!! THIS IS AN EX-MOUSE!!

I love that quote. Edit: It's a monty python quote, about a parrot.

[@dashcamandy2242]

No no! 'E's pining!

[@carnright]

Great video :-D Is it a negative ion generator ;-) ?

[@coolvideoish]

Awesome to see you promoting rechargable batteries.

[@Equiluxe1]

I got a few of those about 15 years ago and back then the mouse detection was via a spring contact suspended from the lid where you thought wires went.The only thing they killed was the batteries so I went back to poison and break back traps which I still use.

[@johnrehwinkel7241]

Perhaps another reason the power switch discharges the filter capacitor is to add another degree of safety so it can't give a delayed zap after it's turned off.

[@Richardincancale]

Hi Clive... What frequency is the step-up transformer operating at - can you loosely couple a scope on to the cool to check? Incidentally it would be a neat little IOT job to add a LoRa board to send an alarm when the trap has tripped, to avoid the rotting dead animal smell @Andreas!

[@Darwinpasta]

I've used these. Only problem we've had was the power switch on top got gunked up somehow, cleaned that out and it worked fine again. Great for car floorboards and places where pets might try to get into it (where you don't want to use the snap traps).

[@d_s979]

It would be nice to have to option of an audible alarm in addition to the green LED. I may go days between trips to the basement and would find it useful if I would know sooner if there was a dead mouse to be cleared.

[@timmgiles]

Used these, I think the same make. Very good. Within 3 days, all the mice in our house were disposed of - 7 mice across 4 traps. There was also a big daddy RAT version :-) but that didn't catch anything.

[@user-li1mj1jx2j]

Why am I watching this and why is it so comfy?

[@neville3151]

The trap doesn't actually electrocute the mouse.....by complex circuitry.... it instantly forces this entire video in to the mouse's brain and causes a cerebral overload.

[@joeyc818]

I love your videos clive I also love to drink when I watch 😆

[@keithking1985]

that looked like a well made trap. but the old one's still can't be beat'in for reliability. i bet a lad could make one of those if he put his mind to it! : )

[@junker15]

I wish I'd discovered Mousetrap Mondays before the last rodent problem. I dispatched them using standard spring traps (which don't work very well -- the mouse cleaned the bait off three of four traps before the last one actually worked). Also, that is the very LAST time I use glue traps. About half the trap had been chewed up and the mouse failed to escape. :o( Next time (and I'm almost guaranteed a "next time"), I'll be busting out the multi-kill version of this trap. Better this than having to have my car towed to get wiring harnesses replaced or finding another A4-sized hole in the filter of the Shop Vac.

[@funksterdotorg]

I bought one of these and it seems to do the job, but it eats batteries. Do you think it would cope with a slightly higher supply, say from a 2S pack of lithium rechargeables? 8.4V isn't too wild for the parts in your simplified schematic but I'm not sure if the omitted parts might mind?

[@ericthecyclist]

I've got a device called a RatZapper which has a bit larger space for the rodent. I was wondering how they sensed the rat without the sense circuitry being destroyed. Now it makes sense. Thank you.

[@everythingFromNow]

The best trap ever - got two mices in one trap. Guess he crawled by his dead friend and got zapped!

[@rangerjones5531]

Honestly, I clicked fully expecting to see a mouse expire!😊

[@LeonardAngussmith]

I did not know that electronic mice were a problem such that we needed traps ........well I thought it was funny. Thanks for the breakdown again.

[@qwaqwa1960]

That must really spew the EMI! All radios in a one-block radius silenced. Good way to know when it's been tripped...

[@greggb1686]

I had one of these - it worked fine for a while until a build up of schmoo in the crevices between the pads stopped it working. Repeated attempts at cleaning failed. It's very hard clean in the limited space with lots of angular corners.

[@Polite_Cat]

thats quite thoughtful of them to include a battery test on each powerup so the mouse wont just get a huge shock and lay there injured.. still, i sorta feel 20 seconds of electricity is less humane then the standard mousetrap that i think kills instantly. i wouldn't want to hear when a mouse goes in there.. you'd hear the buzzing noise and probably the mouse trying to escape and throwing the box around..

[@deltab9768]

I'd imagine it going a bit like this: m.kzbin.info/www/bejne/fYfXpJqkfdWdacU It probably goes stiff and sits like that for 20 seconds while it's paws burn. Then it falls dead.

[@noahhare2272]

Mousetrap Monday has called they want their trap back.

[@treelineresearch3387]

I have to wonder if the op-amp is actually cheaper than using a microcontroller with an ADC and internal reference to measure the battery voltage, but then this design may be 10+ years old and maybe it was cheaper at the time. Also given the lack of an ADC according to the datasheet the op-amp is probably being used as a comparator and outputting a logic level go/no-go signal, so the "battery dead" threshold could probably be adjusted for 1.2V cells by changing a resistor.

[@JackSassyPants]

This is a fascinating circuit, but I'm not fantastic at understanding electronics diagrams. Are there any KZbin channels or online resources someone could recommend on learning basic electronics?

[@fanplant]

Give it a little flip!

[@Datadog-1]

The LEDs lit during the initial buzzing noise which makes me think it’s putting current through the plate to see if there’s a deceased mouse (or other conductive item) in the box

[@stargazer7644]

The buzzing noise IS the trap putting voltage on the plates. You’re hearing the transformer operating.
