Thanks Paul, It is the different size dots that was throwing me. All good now.

OK, thanks Paul, They are not out that much. As you say it is probably the different size dot diameter. I will leave it as is. John

Thanks Paul, I will have a try rotating the dichros and see how that goes. John

I have just received the Laserland RGB 300 mW Module. It appears that the colors are not aligned correctly as it is not a white light when all colors are on and it appears one color is off to the side. Is there a special technique to aligning these lasers? John

Good tip , thanks. I wasn't aware of that product (4Duino).

No problem, Thanks Paul.

Paul, Sounds good. Where can I find some DIY build examples or video with the RGB module?

They look very interesting - thanks

OK, thanks for the info on the link to the analog Module. I will stick with the with the RGB TTL at this stage.

OK, that's great, thanks for your advice. Yes, I will get the shunts for the header pins.

OK, that looks like the way to go with Laserland. I had a look on their site and came up with this unit. Would this be the unit you are referring too? They are certainly cheaper https://www.laserlands.net/diode-laser-module/11010003.html

OK, That is what I thought may be the case 5v = on and 0v = off. Thanks for the clarification. This is the unit I was looking at: https://laserpointerstore.com/laser-modules However, I will have a look at analog power control to get a greater range in colors. Any suggestions where they can be...

I am about to purchase the RGB White Laser Module with TTL from the LPS. I am a little confused how to activate the individual colors. Is it just a matter of applying a dc voltage of 5 volts to the input for the particular color on the board? I have a number of lasers but have not had...

Thanks Paul. It is what I originally thought but as I have had little experience with lasers and like to know what I am up against before I progress in too far, I wanted some clarification. Thanks Paul and guys for your help.

Thanks Curtis, As far as I understand it - looking at the dot from a long distance is OK but not close. Correct me if I am wrong.
