Lawerence Berkeley National Laboratory
When you have everything (scintillator, circuit board) ready, you can assemble everthing together in a box. I'm not going to go into details on how to make the box since it's very easy (if you know how to play LegoTM, you'll have no problem making the box. If you want, you may see the sketches of my design of the cosmic ray detector box.
Well, that's it. Now you can play with it. Do some experiments. Or even go to Death Valley and observe the behaviour of cosmic rays.
