4 x Low Cost 15K Scanner Galvo Set

So I'm looking into Building my own scanner now. And I have a few questions.
What other parts would I need to build a full scanner once I have one of these?
Can I start with one color (532) then add on as I get more money?
How does the analog modulation work? Does it plug in via molex to the DMX?

The basics are as follows.

laser(s) reflect off galvo mirrors. You can add more lasers in the future if space allows, but you need to use a PBS or dichroic filter to combine two colors.

There are two types of modulation, TTL and analog. Either way there will modulation input on the driver. TTL is on or off; there is no in between. Usually 5V to TTL turns the laser on, and 0V turns it off. Analog modulation allows for full adjustment from 0mW to full power. 0V = 0mW, 5V = full power.

ILDA is the standard that combines all of these components. It is a DB25 connector and its pinout is here: Laser Show Systems - Pinouts - www.LaserFX.com

But that's not all! You still need a DAC (digital to analog converter). The soundcard DAC is a cheap and easy way if you are just beginning to experiment. The next step up would probably be a USB RIYA Multibus Lite DAC. drlava was selling them at one point, and may still be.

Finally, it is nice to practice good wiring habits: Laser Show Resource Guide - Projector Connections article - Pangolin Laser Systems

I hope this helps, but the best thing you can do to learn more is read. There is no shortage of helpful resources available.

You can use a DMX controller instead of the ILDA port + DAC, but remember that you can only use the pre-programmed patterns.

Hmm. Looks like they have another one but a little nicer.

$190 each
5 Units x Complete 30k DMX Scanner Motor Speed Kit For Laser..

Looks like those are just dmx, no ILDA. Looks like there aren't any serial ports on the 30k like in the 15k.

@ Laser Freak -> Thanks for the info; much appreciated


I am also in for a group buy, as I stated before. I would be willing to do a GB if no one else is interested in hosting...... ;)



Edit: swimminsurfer256, when you say, "Again, would be willing to do a GB of these!!" do you mean buy one, or do you mean host a GB?

I meant I'd participate in a GB with either the 30 or the 15 (probably preferably the 15).

I'd be willing to host it if you guys want. It's not a problem for me!

I'm in exactly the same boat....I would either want the 15 or 30. And i'm willing to host as well (If Swimminsurfer doesn't do it) :D

Come on guys!!! this is a great deal. Who else is in? :evil:
 
Great info, but one more question. How does the actual laser connect to the DMX?
