Hello
I have been feeding crows by placing walnut kernels on my window sill for a few months. I thought it would be an easy and fun project to place a digital camera next to the window, and let it automatically take a photo whenever a birds flies by to take the snack with him.
My first try was using a laser and a light sensor. The walnut was placed to break the laser beam and as soon as the birds would remove the walnut, the camera would be triggered. This didn't work too well, because the birds seemed to not like the laser-light and stopped getting the snacks.
So my current thought is, I should use something different to trigger the camera. Like a switch that activates when the walnut is removed. A low pressure sensor or just a button which is easily released by a small weight (a walnut weights about 2-3 gram). I looked online, but couldn't find a switch for what I am looking for. I was also looking for pressure sensors but they usually work from 10 gram+. Maybe I'm just looking for the wrong components.
Does anybody have a suggestion on what components could help me to achieve this?
I have a Teensy 3.6 and 3.2.
p.s. This is my first post in this forum, so I hope I did everything right
Thanks
Sam
