Electronic mouse trap/killer
Just Allan
rats (cats? heh)... It used two large capacitors and the base was a
circuit board with some copper etched away, basically so the board was
halved. Food went on the inner track and when the mouse stepped from
the first track to the next it completed the circuit. The shock was
enough to kill the rodent and throw it clear of the trap, which then
reset/recharged.
Anyone have a scan of this old kit, or something similar to suggest?
Before anyone mentions it... It would be placed inside a large wire
"cage" away from kids & wildlife.
Thanks...
Allan.

Heath Young
myth)
- the caps were not big enough (and he discovered the mouse conductivity
index (Mc) was not high enough due to the insulating properties of fur) so
he decided that a microwave oven transformer and the requisite high
voltage rectifier would be an ideal solution. As the voltage was higher,
he reasoned, it should not be a problem with the Mc index. BUT, he
reasoned, the capacitor at only 2uF might be a bit too small, after all,
the capacitors used on the original design were 470uF. So, he went and
found/scrounged a whole heap of 415V phase correction caps, and placed
them in series/parallel to get roughly the same capacitance -
He ended up with 600uF of so at 1200V - he reasoned that it would be good
for rats as well - Apparently the test firing was a resounding success -
the mouse went for the bait, and the trap "fired". The Mc index was low
enough at this voltage that the capacitors dumped most of their load -
about 1000V of it - 200V was all that was left in the caps after
discharge.
The mouse actually did better than leave the trap. It exploded and what
was left was vaporised. Completely.
The shockwaves from the explosion blew the plastic box the trap was
mounted in to little pieces.
It takes 10J supposedly to kill an 80Kg person. That little 50gm(?) mouse
took somewhere around 100J (I think). Try to imagine the effect. Whether
or not this actually happened is another thing, but it is kinda funny in a
sick, twisted way :)
I don't think that the mouse felt a thing.

plague in central NSW and Roger Harrison thought he'd get some publicity.
Only one minor problem. It didn't work. Not at all.
Roger's excuse was that it killed domestic mice but not field mice. Yeah,
right. It sure as hell didn't make any impression on the mice from the local
pet shop. Actually, that's not quite right. It was quite funny watching the
little critters doing a dance each time the thing went off - but it didn't
discourage them at all. They still went for the food.

They aint anything remotely resembling 100% effective.

From memory it wasn't powerful enough so I modified it. Finally it would
blow the side out of a 1 Meg 1/4 watt resistor. Never did try it on mice.
I think the mods involved the transformer and the capacitors. More voltage,
more capacitance.
I used a metal box with insulated top section and a spike. The bait goes on
the spike, the mouse stands on the metal box, tastes the bait and WHAM, one
less 1M resistor.

And thats the evidence that your original 'the only 100% effective

Says nothing useful what so ever about whether even
all pairs of cats are ever '100% effective vermin killers'

Yep. One of the neighbours has a pair of cats and
doesnt get anything like that result on no mice.

By modified, Hi voltage rectification of output
and a added Very high voltage capacitor,
or increased frequency.
Maybe a sensor to power it only when a mouse is present.
ie detect the change in impedance when the mouse
stradles the plate!!
My 10,000 volt fence killed a dumb rabit once.
The fence at that spot was rather low, only
40cm off the ground with twin wires and earth
between mounted horizontally. The rabit jumped up and hit
it. It probably did this several times before meeting its maker.
Spiders also produce a very large zap and spark. In air
the spark is only 3-5mm but across a spider 1-2cm.
At night it can be heard and seen for 100m.
I bult it to stop possums in a orchard. It works
exreemly well. We once found fur embedded in the polly
wire. (ie electric wire). We had no cats or possums
or other vermin penetrate the orchard after that.
Dad once touched it accidentally.
An elephant would not have been as effective.
I tried with a 30cm dry grass stem. Not again!!
I built a tester for it. I glued a perspex box together
with 3 sets of screws screwed from opposite sides and almost
touching in the midle. ie 3 spark gaps.
It worked a treat. It was interesting though. After a short time
I had to srew the srews closer together for it to work.
I found this dificult to understand as the fence was
still working perfectly.
After lunch I tried it again....
KA-BOOMMMMM... perspex glue ... explosive gas mixture...
One LIVES, luckily, and learns...
In the old days for mice they just used a 44gallon drum.
The food was hung by wire over the middle of the drum
and the mice would JUMP for it. When the mice
in the drum stared to jump out it was full.
A mouse can free jump 60cm or so. I tested one.
( with a lot of encouragement)
I also had 2 cats. THey never worked together.
But they where excellent mousers, rabbiters,
bird catchers and anything else that moved
including possums. (holes right throught the cats legs!!)
I had to clear a stack(2-3meters only) of hay
that was infested with mice. I did it very slowly with a
pitch fork. The cats would jump in head first and
pull the mice out. Holding them with a paw they
would look at me and I spiked them and put them
in a stack. 64 mice latter we finished. One mouse escaped.
ie 4 made a mad dash and one got away.
I also recently saw a site where someone had stuck a
waveguide in the door of a microwave oven. This was then
connected via coax to a microvave antenna.
A BIRD ZAPPER??!!!
With the right shielding I am sure a microwave oven
could be made to do the trap job. It would just be a bit slow
and the mouse may leave.

Cats of the 'mousing' breed/nature whatever it is are not common, and are
treasures, I know someone in the country who breeds 'mousers' and still the
offspring are not always 100% mousers, also training is often needed when
they are young.

kill a mouse? (I have seen many electric fences rigged this way) so If you
turn the coil on when a mouse enters it would be very effective. Due to
reasons of cruelty I believe that anything you build yourself will be better
than anything publicly published :-) Good Luck

All dogs have fleas. Some have a lot more than others.

Yeah specially that dried dog food. I just buy it in huge great sacks,
rip the sack open with a knife and let the dog help itself when it wants.

Yeah, by far the best form of antiburglar device.
Handy for some of the neighbours too. One fella used to borrow
tools quite a bit but used to just about shit his pants when he
knocked on the big glass patio door thats the front door and had
the fucking great alsatian leap right up against the glass. He never
did actually turn and run, but he did stop borrowing tools |-)
Posty was even worse. The letterbox was only a few feet away
from another big glass door and the dog used to go absolutely
bananas when he zoomed up on his motorbike, dog inside.
The poor posty was terrified he'd end up coming right thru the glass
one day. Wouldnt happen, they're armoured glass like car windscreens.
Never had any burglars till that dog died of old age.
Main downside burglar wise is the holidays when the dog is usually away with
the owners and aint much of a burglar alarm for the house in that situation.

device. My sister lives near a pub and some take out shops, and there are
stray cats EVERYWHERE anyhow one night my brother in law was walking past
the pub and there was a security guard there. They got talking, and the
topic of these cats came up. The security guard (who had a dog) said 'watch
this" and whispered something into the dog's ear. In less than 10 seconds
this dog had apparently sped off round the corner, and returned with one of
the offending cats in it's jaws :-) Now that's one well train rottweiler
