Parts you need:
1. laser pointer
2. camera lens from small "SPY" camera
3. glue gun or tape
And that's it :) ... just fit the lens to your laser pointer and you have a flash light. Have a look on the pictures.
Step 1: Results and Thoughts ...
I think, for such small 5mW laser it's really powerful. I could see my garden table with chairs that are cca 30m from my window. Have a go ... and you will see.
What I'm planing to do ... to make a small IR illuminator for my night vision. Right now I'm bidding on ebay for 2 IR diodes ... so, lets hope it will not overcome my budget for that project. Any way, my idea is to use these 2 IR diodes to illuminate the distance area ... and use one IR LED diode to illuminate the surrounding area. And these two IR laser diodes would be pointed at one point/centred on the distance of 15m or 20m.
* other advantage of this laser/flashlight is - that it produce focused light ... so it is not that easy to spot it from the side (the same like laser).
Hope, you enjoyed it. Thanks.
P.S. : I did a small experiment with my solar panel (from a small solar light) ... And this light could produce over 70mV.
