you need to figure out exactly what type of diode it is. This way you can get the driver set to the proper mA. Also to make sure you wire the diode up correctly the the driver.
Im building one from him tomorrow if i can get some flux and shrink wrap. My first build. Just be careful using the diode press tool and take your time. You have some options on the mA setting you would like with the kid. Check out the red laser section to find out more info on what setting would be best for that diode.
Yeah, i always put safety first, but honestly, i don't think i will be able to put this thing together!That's a better choice in my opinion. And that also a very bright and dangerous laser and these would be nessecary Eagle Pair® 190-540nm Standard Laser Safety Goggles
Or if you could find similar safety glasses but these are te best
