First, I'd just like to thank anyone in advance for helping.
Okay, so first off, I'm wondering how exactly I'm supposed to power this module: http://o-like.com/b2b_cpinfo.asp?id=966.
I hooked it up to the 5V on an ATX Power Supply. I'm pretty sure the 5V was going to it and that the power supply was on, but I'll probably check right now with a DMM. Basically, I'm not sure exactly how TTL modulation works. I'm guessing it is used with the 2-pin adapter which I didn't plug anything into... but, does it need to be closed in order for the laser to turn on?
Second, I am thinking about trying this: http://www.youtube.com/watch?v=qCUiCs-aYNk, but I have a few questions. I just received these galvos: http://www.laserpic.com/Ebay/Z30%20galvos.pdf. So, in order to do this, how would the wiring work? I wire one keyboard's headphone output to the input signal section of one galvo's amp board, and the other keyboard's headphone output to the input signal section of the other galvo's amp board? If so, I'm a little confused. There are three wires for the input signal (black, red, and white). The manual says the black is ground, the red is +x/y signal and white is -x/y signal, but... what would that be in terms of the wires from the keyboard?
