I want to present my Raspberry Pi project.
An animal friendly mousetrap with photo, video and email function.
You may ask, why somebody would build such a mousetrap?
Step 1: C.A.D. Design
First of all I tried the design in Sketchup 8, which is still free
I could try a few designs virtually to see if everything fits
Step 2: Housing
To build the housing (350mmx110mm), I used 5mm foamed PVC Sheets.
So, I could use a cutter as CNC machine 🙂
Step 3: Infrared Barrier
To detect if a mouse is inside, I made an infrared barrier.
It was build on breadboard for test, but I was too lasy to make my own PCB, so I ordered it in China.
It took one week and the result is stunning.
I want to use an external power supply, but I decided later, to use the 5V from the raspberry pi.
Step 4: Transmitter and Receiver
To fix the IR sensors TEMIC K153P inside the trap, I manually milled two grooves.
They were placed behind the 3mm acrylic glass plates.
As you can see, the 9gr. servo motor is already mounted.
Step 5: Pi Camera with Fisheye
I used a cheap fisheye lens to mount in front of the pi camera.
For mobile phones these lenses are fine, because the phones have an autofocus.
The pi camera has a fixed focus so that the picture is blurry.
I will try to change the focus on the pi camera, but not for now.
