I would probably separate the two modules at this point and see if we can diagnose them separately.
I trust you have no issues changing the colour of the laser just by shorting each TTL pin on the laser board? Power the laser on its own. Shorting the red pins together for example will turn off...
Correct. Just flow the solder nicely so each hole is connected together. Imagine the line of solder completing the circuit instead of the MOSFET. To be clear, this is for each MOSFET, keeping the 3 channels separate.
Good luck with it!
EDIT: I will try to get you a photo to make it clear...
Great to hear! I can’t wait to hear your thoughts on this. Some of the FX are impossible to explain and show to people on camera. There’s one that strobes between all the colours of the rainbow super fast and looks white when it’s still. Wave that around a wall, it’s very fun!
Maybe some photos...
I can’t think what would be causing this to be honest. Could you get some photos of the boards? If I can’t help hopefully somebody else can.
EDIT:
Just a thought. Did you bridge where the MOSFETS should be. Just excluding them will leave the circuit open.
As far as I know it should be exactly the same process. Just make sure the board is the same one as mine and you should be good. Obviously I can’t know if they’ve made any changes since I bought mine. If in doubt I’m sure people here can point you in the right direction.
Thanks for the reply’s. I was beginning to think I’d offended somebody, haha.
But hopefully people starting out will see how easy it can be to get stuck into RGB. This project totally satisfied my need for Sanwus RGB Handheld after I followed his production progress and final reviews. But of...
Quick Intro:
I'm sure the regulars here are familiar with my old thread regarding my experience in buying a cheap ass RGB TTL module. If not, that thread can be found here:

I basically just wanted the cheapest...
Quick update for you guys. I’ve just taken delivery of the replacement diode today. Never worked with one before. Managed to get the old one out and press in the new one. Just tested it to make sure it lights and indeed it does! Yay!
Anyway, after battling with all the glue and pressing the new...
Thanks for posting that. Saves me a job.
I’ve spoke to laserlands some more. They’ve agreed to send me a replacement 505 diode. So hopefully I’ll be able to get it swapped out without too much trouble or messing up the alignment.
I’ll kee you posted with anymore news and will amend my review...
Ah, I should’ve said at some point. The unit I got sent is slightly different from the photos on their website. See one of my previous posts with photos and you should be able to just see the driver board.
If anybody is interested in a close up I’ll post one later.
But my point being, there...
Sorry for double posting.
I’ve messaged laserlands, they asked for photos and then had this reply this morning:
“can you increase the current to the green?the current is not enough”
Any idea how I should respond to this? Surely I don’t have any control over the current to each laser. Is this...
Thanks for the input guys.
It’s 12v across the diode while it’s all connected and running as a white laser.
Diving any further into diagnosing this is probably way out of my comfort zone. I’ll message laserlands and see what they say.
I may end up just writing the 505 off, not bothering with...
