Laser Arcade Game Project

[Quaq]

Hey guys,
Just wanted to show off a project that some fellow students and I have been working on. 
It's a big wooden board full of programmable LED strips and an array of infrared sensors.  The goal is to allow up to four players, each holding one of my 3D printed "laser guns," to target the sensors and set off pretty patterns of LED lights (and maybe sound effects too).  The reactions will be made unique to each player through multiplexing.  The logic is done with a TI Tiva C microcontroller, multiplexors, and IO expander ICs.  We've been coming up with alternate "game modes" to program into the Tiva, like a target practice mode or perhaps a competition with the other players to fill the board with your color by a time limit.

There's our breadboard prototype circuit on the left.  We're testing some code before putting the rest of the LED strips on.

Here is half of my 3D printed gun with a protoboard circuit inside.  We have several differently colored guns for the players.

We drilled holes through the board and set the IR sensors in the holes on the backside.  This helps to isolate the sensors from outside interference.

Here's the team hooking up all the LED strips to the front.

It's not done yet - we are probably going to spend the whole weekend debugging the code 
Let me know what you think!
