Major components as they ended up (swapped a bunch of stuff mid-build -movie magic)
1)Arduino uno
2)Pololu Jrk 21v3 USB Motor Controller with Feedback
3)Concentric LACT2P-12V-20 Linear Actuator with Feedback
4)Luxeon Rebel LED Breakout - RGB Triple Play -(sparkfun)
5)Air pump is a cheapo portable fishtank pump with a gearmotor swap

Building it took about 100 hours + a bit of time on videography, editing, effects, learning things. The test UI you see is a C# windows form I wrote integrated with terraria using tconfig and a custom mod to launch it. I'll post some more specifics in the future
