It looks like I could replace the simple drivers with these and convert the diodes I have to TTL: ebay: 635nm 650nm 808nm 980nm TTL Laser Diode Driver Board 5V Supply Supply 50-300mA (I'm not allowed to post links until I have more activity on forum) Slightly cheaper than new diodes (but...

I wanted the laser to pulse to control heat buildup in my joints as the laser dissipates energy. Not sure if these generate enough heat to be a concern, but if it was easy, it seemed like a reasonable precaution. The laser powers up fine connected directly to the power supply. When connected to...

Also, you are right, I connected it right to the PWM output.

Thanks for the quick response. Here is what I am working with: 5pcs Focusable 980nm 30mW IR Dot Laser Diode Module Parameters: Size:12x35mm Wavelength:980nm Output Power: 30mW Working Voltage: 3-5V Focusable: Yes Laser shape: Dot (Rectangle to Oval) And I am using an old 5v cell phone...

Hello, I am new to this so be patient. Several years ago I assembled a simple red lazer (5v, 650nm) array to aid in healing sore muscles and joints etc. It works great. Wanted something a little more powerful to penetrate deeper into tissue so I purchased similar 980nm diodes and a $6 pulse...
