Wii Turrets

Inspiration

While talking about the ic2 protocol an idea to use the wii's nunchuck as a controller stood out as an idea that was fresh and could interface with hardware elements like servos to give real-life controlling some game like aspects.

What it does

The Wii Turrets will respond to the nunchuck controls: up, down, left, and right to aim a nerf gun that will fire unpon button commands from the nunchuck.

How we built it

Using a mixture of custom modeled 3d prints, existing attachments, wood, adhesive, and metal fasteners the Wii Turrets was constructed. The base was constructed with strips of wood and a 3d printed base, this makes up the bulk of the construction. Electronics consist of an arduino, breadboard, and 6 servos that we use to control the elements of the project.

Challenges we ran into

Hardware projects require a lot of patience and forethought as we ran into mounting issues, tight time schedules with 3d printing, and sideways firing issues when we mounted the nerf blaster the first time.

Accomplishments that we're proud of

A decently working prototype of the project, with a lot of the hardware mounted and correctly working. It was a great group effort and we got a lot of what we set out to accomplish done.

What we learned

Hardware is not to be underestimated, and often requires careful planning. Next hackathon likely choose a smaller size in scope for hardware projects. We learned a bit more about 3d modeling and printing times to make the prints go quicker. We learned about servos and the best way to get all of them on a single microcontroller, but it comes with power contraints.

What's next for Wii Turrets

Wii turrets will likely have a second iteration that will improve upon the mounting for easier use and more robust power system to allow it to go battery operated.
