This whole rig probably costed me about $35 and will last forever. Difficulty: Medium-Easy
Step 1: Basic Setup
For this project you will need...
A Motion sensor......Lowes $20
Some water proof house wiring (gauge 12)......approx $1-2
Leather strip( you can cut a little off of your sons baseball mitt if you have to you only need like 3-4 cm)
An old small tupperware container
Kitchen silicone Sealer ......$2
Replacement plug (in wire)
Outlet cover and box
Aon old watertight container(I used a kitty litter box)
Step 2: Getting Started
First cut two holes in your large watertight enclosure (kitty litter box) one for the motion sensor and one for the power line. where they are put is up to you. Attach the motion sensor to the hole with the appropriate cover seal all cracks with the silicone. do the same with the power line.(see picture below)attach the appropriate wires to each other( power to the sensor).
Step 3: Finish the Wiring
Now add the Outlet box and appropriet hardware to the setup. (I used hot glue to secure everything, the 2 by 4 is for support) depending on what type of enclosure you are using you may need to use a different setup. REMENBER TO SEAL EVERY CRACK WITH THE SILICONE! Now we wait for everything to dry.
Step 4: Choices...
Now you have to choose...
Depending on the type of pest you are dealing with you may have to coose a different solution.
For pretty much any pest i'd reccomend using an ultrasonic emmiter (target, this isn't a good solution if you have a dog or cat)
For above ground pests I used sound in general.
I used a small motor inside a tupperware container full of beads. I attached a peice of leather to the axle for even more noise.
Step 5: Putting It All Together
Now add the solution device to the rest of the setup, put on the lid, plug it in, and TADA! you've just made an extremely effective pest deterer(the one I made worked well on deer, raccoons, and other warm blooded above ground animals. (make shure the setting on the motion sensor is set to 'TEST' mode so that it will only go off for 5 seconds or so in day or night.
Step 6: Other Ideas
-paint the outside to match your decor
-using more wire make an external/extended range motion sensor and hide the box
