That's pretty cool.... have you considered a long exposure pic?

A long exposure would just overlap all over on top of itself, it would be a big green blob! What I need to do is build a amp so I can unhook it from my shelf stereo and run it off of my ipod, then I can take it to the basement or garage and fill it up with smoke. That would be some cool pics!
Anyone know anything about LM3886s? I think I'm gonna use 2 of those.

you should try a simple darlington amplifier to start out with i also have access to those ic's so i might try and let you know but im waiting to get my hardrives mounted so i can start experimentation if you get it to work post pictures please :)

I built this
How to Build the CMoy Pocket Amplifier





Thats the way to do things when you dont have any prototype board :D
I added 2 pots to try to level the x and y movement. The X is much more sensitive than the Y as it is now.

And it doesn't have enough power to run the thing, I think you need at least 10W to get it to move enough. I might look into this darlington amp though...

It would be a mess
A long exposure time would technically be considered as a shot that is longer then the automatic settings.... so even a 1 second shot would look awesome...

I think it will get some cool results...

yeah idk how much the darlington amplifier will help idk the power it will put out depends on how you build it i guess but in simple siren circuits it will pump the volume up. GET A PROTOTYPE BOARD :) also known as a breadboard there only like 15 bucks on ebay.
