Introduction: Humane Multi-Mouse Trap Zapper - No Pain Instant Death

By

Let me start out by clarifying the conflict between "Humane" and "Mouse Zapper".
I have a major mouse pest problem where they eat all my dog and parrot food every night - and many of them .
I tried purchasing several mouse traps which all face different drawbacks:
1. The sticky pad - the mice glue themselves and for hours struggle to get free exhausting themselves to death and die of hunger.
2. The pipe trap - locks them in and then they eventually suffocate after hours - Very bad!
3. The box trap - sometimes cuts their tails when it shuts and what do I do with them then?
4. The standard smack trap - fast death (50% of the time) but only gets one mouse .

So .. I devised this multi-mouse quick death trap using an Arduino which zaps them in the head for 2 sec killing them instantly with no pain (same as done on larger animals human eat ).

Step 1: How It Works....

Here is the back side (end) of the mouse path .. When it reaches the bate it is sensed by an IR sensor which the Arduino senses and activates the zapper

Step 2: The Trap Door

In this picture you can see the trap door activated by a standard mini servo located under the floor..
See details in picture

Step 3: Video

I hope the video of the zapper working with run properly .. I uploaded an MP4 from my cell phone....

    else   digitalWrite(relayControlPin,HIGH); // No Shock

  //Serial.println(NoseLocationVal);
