Topic: New guy, Before I go out and start buy a laser projector.

Hi all,

I found an instructable on building your own ardoeno based laser light show. It uses modified  audio speakers as galvanometers. I then immediately ordered all the parts needed.

After sparking my interest, I found laser boy and really want to jump in and play.

My question is what are my options if I want to continue down this slippery slope?

Are the RGB ILDA laser projectors out there for under $300 even usable?

Do people here make there own?


How much will this realistically cost me for a small hobby project.

First of all, welcome to The LaserBoy Forum!

Yes. Many people here have made their own RGB (V) projectors, including myself.

As far as I know all of the really cheap pre-made projectors have an internal controller that reads from an SD memory card.

A lot of people actually use LaserBoy to make the specific kind of ILDA files needed to work on these systems.

You could also get one and modify it by adding a DB25 ILDA port to it. Then you could use a modified sound card (aka LaserBoy DAC) to control it (or any of the other ILDA complaint DACs).

You will find they are also TTL modulated lasers. That means they only go on or off. There is no control over intensity. So you only get 7 color combinations. That part would be a lot harder to upgrade.

James.
