If you are into building things from scrap materials, here’s a fun DIY you can make at home and it’s a pencil sharpener machine.
It’s basically a sharpener with electric motor and you’ll need no more than just a DC motor, sharpener, plastic bottle, battery, switch and a little of epoxy adhesive. A very simple build from a creative and intelligent idea.
Well, if you’re someone who’s just into mechanical pencils and have no time for this, then this isn’t for you to try. Otherwise, you can check it out with the video below.
