Tired of changing batteries so often?
This time I’ve decided to hack salt and pepper grinder to reduce battery waste going into the landfill.
As many of you probably experienced, battery grinders don’t last too long. But there is an environmental friendly solution for this. It’s enough to turn it into grinder powered by 9V power supply. And it’s all made from reused parts 🙂
Socket was taken from the broken radio. Live wire goes straight to the motor, other one goes to the switch and further to the other pole of motor.
It took me a while to figure out where to place the socket, but at the end there is a space in the structure of grinder. It works great, and now I don’t have to worry batteries will run out during the romantic dinner 😀
