Catch an Escaped Hamster With Surplus Electronics





Introduction: Catch an Escaped Hamster With Surplus Electronics

Hamster got loose?
Have a bunch of surplus elecronics?
Time for some Hamster Sensing Technology.

Step 1: Assumptions

This assumes...

The hamster is coming out at night and eating food left somewhere.

That big pile of misc electronic crap you have includes:
- Something that will sense a hamster.
- Something that will wake you up.
- Something that will interface between the hamster sensor and the waker upper.

Step 2: Hamster Sensor

What made this possible and REAL STINKIN' EASY was the opto detector some friends had given to me. I had a feeling that some day it would come in REAL STINKIN' HANDY.

Give it 12vdc power, it sends out some kind of light beam, something gets in the way and reflects the beam, it outputs 12v on the output. Simple.

Step 3: Waker Upper

I picked a flood light as the waker upper. Shined it where I expected my head to be later that night.

Step 4: Interface

Opto relay from some scrapped piece of test equipment. Input 3-32vdc and it will switch 120vac power. It was already wired in an extension cord and the hot wires insulated. Kind of sort of semi-safe*.

*WARNING - This is 120vac power and will kill you dead if it gets a chance. Also it should have a fuse. And a heat sink. And be in a box. And other stuff.

Step 5: Hook 'er Up

Place the Hamster Sensing Unit so it's looking at the food.
Connect 12vdc to the opto sensor.
Connect the Hamster Sensing Unit to the opto relay.
Run a long cord to the floodlight near your bed.

Step 6: Blink Blink Blink

Huh? What the...? Who's flashing the lights?
Oh yeah, hamster!
Get up and find hamster acting all Mr. Casual like.
Put in cage.

    Always tought of something like that, but just leave the cage open in the ground with food. Hamsters come back home after a while if they can find their smell on it.
    Anyway, Nice and cheap setup good work!

    umm... i would rather escape-proof the cage instead of all that...

    May I offer an easier answer (and I'm sorry it doesn't involve tech...) You need rodent food, a bucket, and a couple of bricks. The bucket can be any material as long as the rodent can't climb out of it. Stack the bricks to make steps to the rim of the bucket. Place a very small amount of food on the steps. Place a larger amount of food, with a carrot or peice of fruit in the bottom of the bucket. My family raised many different rodents to sell to pet stores when I was a kid and this was one of the best ways of getting the guys back...

    i did that to try to catch my hamster when it escaped and it chewed through the metal bucket 0.0 i have no clue how and i'm pretty sure it was her cuase she also chewed out of her steel cage.

     The super hamster strikes again....

    Damn! WTF kind of hamster did you have?
    that said, the one i had ages ago was pretty psychopathic. The little £"%$&£!%%&%&&%%&%&'d squirm and bite and would run around like mad.

    i got a rare pic of that hamster:


    That explains quite a lot.
