My raspberry pi revision 2 couldn’t provide enough current to drive my relay board and lift the chickens into the air. See those black and red wires I soldered on? Well now my pi can. My electronics lecturer would be proud of me.
After our local rat hobbled off with my springy rat trap Oliver and I decided to follow some plans from the internet and build our own home-brew rat trap.
We had to dig a hole in the ground and insert a smooth sided bucket
Then it’s necessary to thread some stiff wire through the centre of a corn cob so that it can spin. The idea being that the rat crawls along the wire to eat the corn, spins around and splashes into the water below…and drowns.
I haven’t caught anything yet but as usual I’m eternally optimistic, and if in a few days I still haven’t caught anything then I’ll add peanut butter.
