    I was interested to see that electronic traps had largely replaced the
    spring-type, on the stand in my local farmers' shop.

    Now the blurb on the box stated that 4xAA cells would kill ~50 mice.

    If, very roughly, 4xAA gives 20kJ - that's 400J per mouse.

    Which, if you pardon the expression, seems to either be massive overkill
    (10J being enough to put the average adult female human into VF) - or
    pretty inefficient design..

    Anyone know what the electronics design of one of these units is?

    Incidently, the average mouse weighs around 20g. 400 J should raise its
    temperature by around 20 deg C. So, are these units not actually
    electrocuting the mouse, but cooking it??

    Not that I remember. I might buy one and find out.
     

  3. Actually you would be better off cleaning them and cooking on sticks with a
    satay dressing.

    I was interested to see that electronic traps had largely replaced the
    Funny; I was just looking at the same thing in a farm catalog today.

    I'm not going to bother with the math, but ... after the first kill I'd
    assumy the batteries have xx% energy remaining. yy after the second,
    and zz after the thirs, and so on. So I imagine the juice is adjusted
    to insure enough left at the 50th kill to do so successfully. Time
    would also be another factor of course, plus ...

    But mouse jerky doesn't stink.! Sticky traps do stink but squeals of
    distress can drive other mice away. This observation is based on: "in
    matters of survival, mice are smarter than humans."

    Why should it need to consume standby power? The mouse can switch the
    thing on...

    Say with a hinged small section of internal wall which operates a
    momentary connection trembler switch, when it is displaced. That starts
    up a step-up inverter that puts, say, current-limited 1kV between two
    foil strips running the length of the floor of the trap, for one second.
    Delivering it straight into one pair of feet and out the other, with
    the heart in between. IWHT 4J, per mouse, more than ample.

    Of course the motorised belt that runs up the middle, to remove the
    remains into a suitable receptacle and clear the trap for the next
    volunteer, would use extra - say another 4J.
     
  7. Sorry, but I don't care much for this Item, I use Electronic Pest
    Repellents and let mice and rodents roam free outdoors, where they
    belong as food for and playmates for cats and birds.
    It's better than having them dead in my house, no matter how clean the
    disposal system is in those Zappers.Since I placed a few on certain
    outlets they just don't come inside any more.

    BTW, I didn't call this group "Trolls", only those that respond as
    such., and there we have it.

    I'm all for fun-tech gadgets, but what's wrong with the age-old,
    tried-and-true snap trap? Fold the spring back, a tiny dollup of peanut
    butter, set it and forget it. Check in a few days, remove the whole thing,
    trap and mouse to the dustbin.

    Around here, simple spring snap-traps are so cheap, you can through them
    away with the mouse. 90+% of the time it snaps the critter's neck so fast
    he doesn't know what hit him. No squeals, pretty humane way to kill the
    things.

    Oh, it's just me - take me to a moonlit meal overlooking Lake Geneva
    and, next thing you know, I'm looking at the power transmission line
    pylons going up the cliff, trying to work out the voltage... :(

    Show me an electronic mousetrap and I'm not thinking about the "poor wee
    timorous beasties", but why 4 x AA batteries, what the sensor is, etc, etc..

    Snap traps have their advantages, but triggering is often hit or miss.
    Electronic traps overcome the triggering problem - but, as another
    poster has described, the death isn't instantaneous. Plus the cost at 1
    AA cell per dozen mice is high.

    Maybe the solution is a hybrid - a mechanical spring trap with an
    electronic sensor/trigger?
     
  10. You're an idiot if you think electronic scarecrows work.
    I have a bridge over in Brooklynn I'll sell you.
    And such you are.

    The Brooklyn Bridge is not for sale

    Now you are attempting to defraud the group by posting false sales items
    you are so low down and evil Zeus will strike you dead

    Prepare yourself for death your superior homosexual cybernetic days are

    You are an authoritarian homo deviant
    not an authority in this group

    Cease your little charade and reveal your true self to address control
    issues in person or I will continue to ream the control complex out of
    you through your cyberanus which is splayed out in the open here in
    every post you make

    Your only option is to leave this group in peace or you will leave in
    cyber pieces

    Regain your honor
    Uplift a planet
    And part

    Then I will take you to Olimpus

  13. How would a retarded **** that thinks wall plug bug scarecrows actually
    work,know what is or is not for sale?
    You're a goddamned idiot. This is not a for sale group and sales posts
    are not allowed here. If you think that is hat I was doing to the Roy
    Retard, then you are an even bigger retard than he is.
    Get the **** out of Usenet, you pathetic little twit.
    **** off, you inferior piece of whale shit.
    You're a goddamned retard.
     

  14. You're a goddamned retard.
     
  15. You're an idiot.
    You obviously do not know much about my nymsake.
    I'd like to part your scalp with some small lead pellets.
    If you could spell it, you might have about one millionth of a gram
    more credibility than your current rating. Both are at NIL values.

    Hint. The word has no I in it, and it has a Y in it, you fucking
    retarded little adolescent twit.

    You and your band of trolls are like the Al Qaeda of this group you are
    most likely accessing from a cave in the mountains of Afghanistan where
    the Taliban supply you with ill obtained technology and bootlegged
    software from their poppy sales and treasonous spies

    Your ticket to Olympus has been cancelled
    you are now in our celestial no fly list

    Zeus will deal directly with your insubordination

    I will just ream you a new anal aperture for your crossing over the
    river sticks I will enjoy seeing the crocodiles eat you up better that
    way

    Be aware that I know that you somehow tamper with precast material your
    moronic deceit is of no surprise to me or the group it is just another
    fine mess you got yourself into

  18. Notice the threads where proper electrical engineering discussions are
    taking place RoyTroll. Notice also that you are too goddamned stupid to
    have even the simplest participation in them. Why? Because A: You are a
    goddamned idiot that has a fantasy about having electrical knowledge. and
    B: You are, in fact, the troll. Romping through the group and making
    your retarded gay stabs at those that have found you out, and anyone else
    that disagrees with the stupidity that encompasses your pathetic life..

    You are truly pathetic, RoyTroll.

    Ah, you faggoty fairytale monsters are all alike, you truly are a sack

    There ain't no at those that have found me out fool.It's just you the
    retarded idiotic faggot, and that machine dude., that doesn't know a
    thing about eletricity, but allot about horseshit, trolling a group and
    abuse.....

    Go to hell, you post abusing piece of shit.

  20. Archiemedes' now I see you are a Suspected Al Qaeda Operative..it was
    an electrical thread until you grossed it out with your insluts and
    troll menality - You shouldn't even address my post, what are you in
    love?., everybody needs somebody to love...You had that someone..but you
    became a Troll - I never gay slurred you, you done it to yourself.Now I
    have my time and your ass is tall grass with the wind blowing over you,
    in time the rain will fall on you and you'll be cut off for harvest
    time...

    Take the music with your whole body and leave me alone, now.
