My final project will be a hands-on two player racing game. Each player will have a remote with two buttons on it. The remotes will control and drive a stepper motor. When each player push the buttons on his remote, the stepper motor will move. The faster you push the buttons, the faster the motor goes. I will design and 3d print characters that will stick to a laser cut piece that will stick to the stepper motor. A thin plate will seperate the motors and the moving characters. (Mynd) I have decided to call the project FAB Sprint.
When i started Fab Academy my idea for the final project was to make some sort of synthesizer. My ideas have changed throughout the weeks but now i have made a final decision. The motor game idea came up in the machine week, which was a group week. I came up with the idea to make some sort of motor controlled game but the group ended up by doing a multitool cnc machine. That allowed me to continue developing the motor game idea. My concept now is very similar to my original idea.
I want the box itself to be a press-fit box. To have the project as cheap as possible i will most likely use birch wood for the box. I will use two stepper motors, the ones we received for the machine week. I will create the two remotes using a two button circuit i will make in the lab. It would be nice to 3d print cases around the circuits to make them look more like game remotes. I have to create two stepper motor driver boards, one for each motor. The components for the circuits should be available in the lab. My characters/figures will be 3d printed.

I will go into more details into these topics on my final project page
I needed a case around the stepper motors and the boards
To include as many processes from the fab academy i decided to make a press-fit wooden box
I used the 3d program sketch up to design a birch wood press-fit box fo my final project
I then imported the file to VCarve Pro and used the Shopbot to cut the box out
I needed a plate to put on top of the press-fit box
I started off by cutting out paper prototypes in the laser cutter and when i was happy with the size of the plate and the holes i was clear to cut out the plexi glass
The 3d printed characters are supposed to stick up from the plexi glass plate.
I designed some kind of stand for the 3d printed character to stick onto.
I will go into more details on my final project page
I decided to use the 3d scan of my friends face from the 3d scanning and printing week
I printed two of them in different colors
I made two boards for each stepper motor
One button board and one motor driver board for each motor
I will go into more details on the boards on the final project on my final project page
I used the 3d scan from the 3d scanning and printing week
The plexi glass plate and the character holder was cut out in the laser cutter
The press-fit box was cut out in the shopbot
I designed my own circuits using input and output devices
This is written after i have finished my final project so all the tasks are completed now
It would be nice though to 3d print some casing around the button circuits to shield the components on the board
Will this project be entertaining and be a good example of a doable fab lab project for people starting out in fab labs
-24.May-14.June: Final Project development
15.June: Final Project presentation
I want my final project to be up for showing in Fab Lab Vestmannaeyjar and let people try it out
I will consider the project to be a success if people find it entertaining to play with and also if they want to make their own version of it
