Another group had a foam cutout of a three-fingered-hand and they didn’t need it so they gave it to use so we decided to paint it green because salad fingers is green and then we stick a wooden stick into it.
Then we thought we should make that hand slap a piece of paper and make hand prints we figured out how to make a motor spin up and down and out a gear on it and tried to glue the foam hand’s stick onto that gear so the hand will move up and down, But the foam hand was too heavy so the gear kept on falling off
We decided to make the hand cutout using craft foam so that the hand will be lighter. We made two of them and glued a stick in between them
We decided to make a cardboard box and make a slit going up the middle and put the motor in it and have the circuit board and all the other wires back in the box. It was very difficult to get the motor wit the spinning part sticking out and the box part of it behind the cardboard wall, but we eventually managed to squeeze it in there.
When we tested it it was too hard to put paint just directly onto the hand. so we just put two different colors onto a piece of paper and let the hand mix them to make a different color when it came down We found that the paint splatters and it launches little blobs of paint when the hand comes up and down. In this picture, we put down blue paint and the hand mixed it into purple
When we made the coding, we made a button that makes the hand start going up and down, a button that makes it go faster and a button to stop it. The slower button stops for half a second every time it goes all the way up or down. The faster button stops for one tenth of a second every time.
