Tell me the outer diameter of the Radio Shack speaker for this kit so I can update the design.  I made the box after I lost track of the speaker so this box is designed for a 32mm speaker.  I did add another speaker mount for up to a 52mm diameter speaker like what you can get buying those little amplifier balls at the Dollar Store for $1!

I bought a Radio Shack Theremin to play with, to experiment with to see if I could control it with my "RoboGuts™ S.T.E.A.M. Education Program " for another X-Project ... so far not any really good results ... but still the little box makes the Theremin more fun to use.  

You can see how I added a LED into the hole above the photoresistor ... I used a 3-color LED, but probably would get better results with a plain white LED.  I'll give that a try when I get one.
