RGB Projector finished and LEGAL!

I posted a few weeks ago when I finished putting together my first RGB projector, but now I finally included all the goodies it takes to make it legal.

Here are some details:
Green = ~30mW @ 532nm
Red = 200mW @ 658nm
Blue = 50mW @ 473nm

I made the custom box out of sheet metal and I added a 1/2" piece of MDF board to the bottom to help keep the optics stable and to save on weight (the whole box weighs about 10 lbs).

Here are some pics:

First the safety features.......

All I need now are the stickers, and the VARIANCE!!!

Now that everything else is done, I have no more excuses for laggin.

:shock: :shock:

Wow that last beam picture there is one of the BEST picture I have ever seen from a RGB laser (and with so low output in mW) !!
I dont understnad how you do it :p

I think I need to take more photos from my RGB...
I never get my photos that good...... maybe I got fooled and my lasers is only 10mW :roll:


You have done a great job :) it`s just sweet..

Very nice pics! Good job on the projector. Let us know how the variance application goes!

Adam

can you e-mail me that ILD file you did use to create the last picture there ? :D

Sorry for posting this topic twice (in two forums). I just noticed that sometimes people post replies in one forum but not the other and vice versa. I can't tell sometimes which place is best to post topics, The Lounge or Lasers?????


Anyway, sorry for ignoring your question liteglow, I was trying to find an answer for you. When I originally bought my first system, it was for a small, single colored laser. When I wanted to combine the lasers, I made a bigger box but kept the same back panel since it already had all the cutouts for the connections etc. Basically, the labels on the back were done professionally, not by me.

As for the picture, all I did was create two parallel lines of about 30 beams each, set the color change to continous and slowed the scanrate a bit. It also helped that the camera was on a table. Everytime I took a picture holding the camera, the shots came out blurred.

Hope that helps.

BTW, can anyone that has done the full variance paperwork please send me a PM, I could use some advice!

thanks,

I would be interested in that as well

Its not too bad. I varianced a projector about 2 1/2 years ago. Took me about 2 weeks to get all the paperwork in order and sent off. Then it took about 6 months before I got an approval. I know there are several forms to fill out, plus you have to have a drawing of the projector and a manual. As well as a few other things. I know there is a web site that has all of the forms as well as info on what they need. I don't have the link anymore though. I am getting ready to variance another projector so I will dig up all the info soon.

I think you will also need a case interlock as well.

I heard that you don't need a safety interlock if I am the only one that will be using the laser. Something about having one would be "protecting you from yourself". Plus the projector uses screws to close the lid.

Is this true???

Is there also something about an emergency kill switch/button?

Jim

Sorry for dredging this post up, since if you submitted your variance paperwork you'll already know this. I'm just adding this footnote so it's recorded for others also going through this process.

The laser emission indicator light must be on the same side (and hopefully near) the output aperture. From what I can tell from your photos, the light is on the wrong side to meet the requirements...

The other thing, which you may already have done, is a 10 second power on delay for the laser. The "cheap" solution
to meet this requirement is done by using an "ignite" switch that is disabled for 10 seconds.

Aside from that, it's a good clean implementation!

For most systems, the emergency kill switch is handled on the laser controller side, though if your controller does not
support it, then you'll have to think about how to wire one in to the projector. This can be as simple as routing a remote
power switch.

:lol:
That's funny... You have the same exact blue and red lasers I have, AND the same power green... :o Makes a nice white don't it? :D Nice projector!!!
