It is at Milo's house in Oakland.  


If you want to use it you could probably ask him for it and he might give it to you, if you have a good place to put it.

I have used it a few times and in my opinion it is just a toy, I haven't been able to get any good images out of it.   
But if you want to work on it and make it better it might be able to give you really good images.   Needs better image processing, the tv is not sufficient really.
