Beam scanner galvo and actuators

[Stuka]

I'm interested in possibly adding an open loop "beam" scanner to my projector plan, similar to the "Skyman" product offered by Technical Artisans. I'm looking for something I can modulate with an audio signal or by "manually" varying a 5VDC input voltage.

Can anyone recommend a source for a comparable REASONABLY-priced galvo and driver circuit?

I would also be interested in a source for REASONABLY-priced TTL-triggerable actuators to be used for beam routing.

Unfortunately, I still don't have access to an Internet connection that allows me to search Ebay - hence, the questions!

Thanks!

GM20's will do that.



This driver schemetic is designed to be used with a line level audio input. It can easily be modified to be used with alternative inputs

stuka-
by far the most shows i have done have been dmx controlled.
not that you are planning on using dmx, but one feature i like in my dmx setup and that i miss having in my computer controlled set up is the ability to run a signal from the djs mixer right into the board controlling the laser.
i am able then to adjust the input on the dmx's audio slider and i can get really nice results.
and that's just with a clunky motor actuated beambox.
i think it would be sweet to have direct music signal to a computer based system giving you the chance to make your beam show dance with the beat and not just on the beat.
