Single Piston Auto Tapper

I am playing tap my Katamari. It's a very simple tapping game, but I grew tired of tapping myself. So I built a machine to tap for me!

I just added a small motor, 9v batter, and a switch, and presto, a tapping machine!

I used the single piston designed by sirmakesalot. I tweaked the piston for the radius of my stylus, and added a small hole in the middle of the Gear Housing Axle for the motor spindle.

Then the stand is hoist it all above your phone.

Ah pistons, the best way to translate rotational movement to vertical movement!
