When the robot overlords take over, they'll need to use our etch-a-sketches. Here's how to let a computer draw vector art using your favorite childhood toy.
**I'm going through and finishing a slew of old instructables I never published. I think I made this one sometime last year. Enjoy!
So, there I was, skipping class at MIT and hanging out at my favorite machine shop. While I was sitting in my favorite comfy chair, a flash of red shining from beneath a pile of books caught my eye.
"Aha!", I said, "What could that be?"
Further excavation yielded a classic red etch-a-sketch, perfectly preserved since Steve Cooke left it there twenty years ago.
I thought to myself, "I hold in my hands a perfect basis for a computer-controller vector drawer"
A maniacal grin crept across my face as I felt my plan grow to fruition inside my mind.
This, my friends, is the true story, complete with instructive pictures, of how a person such as yourself built a computer controlled etch a sketch. Sure, it's been done before. Now you can do it, too.
So, what are you waiting for? Skip a class and go build something!
Step 1: overview
The general idea is this:
you're going to take an etch-a-sketch, pry off the knobs, put motors where the knobs once were, and then build a circuit that lets you control the motion of the etch-a-sketch from a computer
