Tiny Pots?

[rog8811]

where can I get the switches that reverse a motor

You can get them here

If you get the centre off version you can do both directions and off.

And you wire them like this......

Edit:
And also, how do you get these amazing patterns:

I don't know if anyone has commented on that, but since its my picture I can tell you that the factor that contributed the most to that picture was a long exposure time .

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.
