Would you like to show your electronics creation to your friends?

When I was eight, I made my first game. A wonderful game for a kid like me.

It was a simple piece of rigid wire twisted around, connected to one pole of a battery. The other pole of the battery was connected to a lamp and the other pole of the lamp was connected to a round wire.

This round wire was inserted into the rigid wire. When the rigid wire and the round wire touch each other, the lamp comes on.

The game was to run the round wire on the twisted rigid wire without letting them touch.

Yes, it’s a very very simple game, but at that time there was no Arduino 🙂

So I played a lot with this game and I told my friends how fun it was! But they didn’t understand much of what I said.

That’s because my game was in my garage and I couldn’t show it to them!

Until I made something simple, portable and easy to explain to my friends!

It was a “Color writable compact disk” 😀 Basically a mini DC motor, connected to a battery, with a round piece of paper on the rotor. The motor spun the paper, and my friends and I colored it while it turned.

Really a lot of fun!

But why am I telling you this story?

Because if you want to make something to share and play with your friends, if you want to make your own game, KeyChainino is for you!
