Not with a basic stamp you could do it with an SX, then your galvos would also have to be able to move way faster that a stepper drive and be accurate at each laser turn on and off time. With the right hardware the programming would be a piece of cake.
If you take 50 beams of laser light rotating between them 30 times per second you need to move the mirrors 1500 positions per second. The most I could get is 60 or so with the stepper motor, like I said I don't have any real galvos so I have no idea what speed they can me modulated at.
That is why real galvos are so expensive, because they can do these things. Just take out a loan.
How do you think it should be coded. Really Andy, if you have enough smarts to design and implement a web site like yours and to work safely with high power lasers I would think a simple High and Low command would be something you would have learned about coding over the past few weeks. Please just spend some time turning on and off an LED. Why not run some longer wires from the stamp in your laser box to an external breadboard, just a few pins you can work with for output. I am not the hardware guy, I work with software algorithms. Post a program you wrote that you are having a problem with and I will be happy to help but I can not give advices on connecting high power lasers and basic stamps I do not have a degree in EE I only know enough to be dangerous to myself and I don't want to endanger anyone else or blow up your hardware with the wrong advice.

Think Inside the box first and if that doesn't work..
Re-arrange what's inside the box then...
Think outside the BOX!
LOL i know what your getting at but i didnt do my web site someone did it for me. OK i know alot about laser ill give you that!!
ill see what i can do.

Very good sir. I knew you could do it. When you have an interest in learning something nothing can stop you.
Next step is to move your mirrors turn on and off the laser so you get 4 dots on the wall in a line instead of a line. That will give you the effect of what you see in the movie. Not as many lines but lines separated by spaces that fan out. Then you move your timing back and forth so you see 4 dots on the wall move back and forth. Keep going baby steps, see what happens when you speed up the on off frequency things like that.
I am kinda busy as I just got two 1000 page manuals I want to finish reading this week. Good job keep it up.

Cheers mate, well ive taken everything apart at the moment, as im getting a new BIGGER box to fit everything in tomorrow.
so i cant play for a few days till i put it all back in.
1000pages!!!! i hate reading and im very poor at reading, thats why im no good at coding [noparse]:([/noparse] LOL

I was just bouncing around forums and saw this one and you guys mention mirror usable with lasers.
For whatever it's worth:
For cheap front surface mirrors take apart a·kaleidoscope (one that has glass mirrors, obviously, not plastic ones) . You can get kaleidoscopes for a couple of bucks at a gift shop or big dept store etc.
That's what i used for my 3d profile scanner a couple years ago, they worked great.
first surface mirrors can be found at thrift shops in overhead projectors and old microfichs- es old classroom projectors and the always seems to be a ton at
my favorite thrift,- scanners. but them are only 1/4" wide and 4 or 5" long. The CD drives have approximately 1/8" beam splitter mirrors. Anchor
optics or their other company Edmund Scientifics (great grab bag lenses)

Here is a nice link for you. See the links page. Lots of information on how to do what you are looking to do.

ive seen that web pagw before but didnt find it that useful as he using a professional kit and im not.
im gona connect the TTL up to the stamp metron. Red to the pin and black to the - on the stamp, what coding do i need???

up to the VDD and the VSS, it wont affect the power going to the digital pots or what ever else is connect to the VDD and VSS will it????

i would like to thank everyone on here who help espically metron massive thanks to him.
im gona move onto differernt stuff that uses software rather than coding to make it work.
