So I’m looking at using both an arduino and audio dac solution with a switch between. There’s a few animations online to be done through audio and an arduino can be used alongside for safety as well as controlling simple patterns as well as colouring. I have reserved tomorrow to design a pcb!

Ahahaha!! So development, ive not even looked at your link but I have already ordered one along with a salvo unit. The only difficult part at the moment is the software to drive the darn thing....

Really brief question (hopefully) taking the following product: ebay.co.uk/itm/Focusable-12V-500mW-808nm-Infrared-Laser-Diode-Dot-Module-TTL-Fan-Cooling-Kit/193179877367?hash=item2cfa6afff7:g:l6sAAOSwQ69dtquT Whats the likely hood of being able to replace the LD to maybe a red green or blue...

I'm always up for looking at code! I suppose this also replies to @paul1598419 I could use PWM to control the laser power in order to get a better balance. But my first call is to buy lasers. Im thinking mainly about cost here but here is my idea so far...

Excellent info, yes I will be buying the diodes and a small driver board. Thank you for the information it’s really well received. I’ve had a few technical projects prior to this and I feel that I’m up to scratch. I found arduino sketch someone made which incorporates a single laser and I will...

That’s an interesting thought and wow, ok I will probably buy some LDs with a custom driver to get them working. I suppose one benefit is the cost; the LD will be super cheap at this power. I would of thought I needed more power if the beam was moved all over the place.

Hello! I've just stumbled across this forum due to inspiration to create my next project; Laser projector. As a bit of a background im an electronics engineer now software developer and so therefore my physics/optics knowledge is very limited! I've looked through a handful of pages and found...
