Perfect. Now what I really need is a sugar cube camera with RGB output
and a 3 x 3 matrix, all for (say) $50.00 :)

Don't forget "consistency" as well. I've had some great deals from
surplus suppliers ... and a year later when I want some more of the
identical thing, they're gone.
I like surplus stuff for fooling around and experimenting. But when I
start designing something for a specific purpose, I don't want to
compromise good design just to suit the parts I happen to have.

some Nus to make it do stuff!!! COOL!!! I may have to try that one as
one of the projects in my class!!! Such great ideas! I sure appreciate them!
