Default Re: Tiny Pots?

Another thing that gives more varied patterns is a large adjustable speed range per motor...

That picture was three lasers (20mW green, 5mW red, 100mW blu-ray) all pointing into the same spirograph (held down using tape/sticky tac). It looked ok in person but the exposure was along the lines of 1/4s so the pattern will fill out a lot more and become more complex (In person it just looked like a figure 8 spinning fastish).

I find that lasers almost always look better in photos.

Just a quick question. Does anyone know how much (approx.)shipping to canada is for a few small parts from digikey. They don't say.
