Last year I was asked to repair the Minnesota RollerGirls T-Shirt Cannon that failed mid-season.  I created a temporary fix, just in time before the game. The repair got us talking about the future of T-Shirt launching technology. What would make this cooler? How can we improve this technology to make Launcher 2.0?

Minnesota RollerGirls’ Wet Spot (Lucas Saugen) and I started brain storming.  We met for lunch and started throwing around ideas.

What could we do better? In five years, where will the technology of T-Shirt launching be?  How can we make sure that there wouldn’t be a T-Shirt Cannon technology gap at the Minnesota RollerGirls?

Also, how can we make it so that the darn thing doesn’t break every season.

This blog post details some of the build, process, and technology that went into making the new Raspberry Pi powered T-Shirt Cannon for the awesome Minnesota RollerGirls team!

First we came up with a list of things that we wanted for the new T-Shirt Cannon. This would ensure it would be a viable technology for future games and entertainment.

Our Ideas:

  • Tweet – (Yes, Tweet when it has launched a T-Shirt)
  • Camera – To capture that special moment of hitting someone in the face.
  • “Capture all the stats!” Tweet the stats about the launch
  • Launch more than one shirt in a time-out period, which is ~60-90 seconds.

We also got ideas from the teams:
