Here's a simple, cheap and powerful laser I built today. It puts out a stable 160mW over at least 5 minutes without ANY signs of warming. [highlight](be sure to scroll down the picture to see both lasers)[/highlight]
(the other laser is a mini dorcy mod I did that puts out about 115mW and is VERY stable over at least 5 minutes. I used a LOT of solder as a heatsink within the head of the mini dorcy and ground down the head of the mini dorcy to allow it to fit within the blue heatsink.)
I hope the instructions are clear and I didn't miss anything... :
notice the open air space within the red heatsink - plenty of airflow around the diode, module and shaft collar
it uses 2 c123 batteries and the power could go up if you use a smaller resistor. My next one will use a 7.5 ohm resistor or maybe even 5 ohm.
instructions follow this post and the pictures will help you understand my instructions.
Sorry about the size of the images - they're big so you can see it better. The total setup cost about $40 and the component list is the following:
metal gear flashlight
diode
aixis module
heatsink
10 ohm 1 Watt resistor
switch
1/8" 4"x4" rubber sheet
1/2" shaft collar
copper washers
wire, solder
