Transform Your Laser Pointer to a "spot-flash Light" :)

Hi ... in this ultra easy instructable I will show you, hot to change your laser pointer to a (spot) flash light.

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 add two pictures, just for imagination, how powerful this laser/flashlight is. These two pictures have been taken from 5 and 4 meters distance - in complete dark.

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.

    It's dust and dirt ... and the big long line = scratch - I scratch the lens :(

    Not necessarily. I shined the laser through a drop of water and the circles and lines were still there, except moving. So the long lines can't be scratches if they move.

     Yeah I had that kind of thing too. 
    I asked my optometrist and they said it was little bits of dust + stuff floating around in there. nothing to worry about, apparently.

    Yeah its great to achieve Laser Fusion Milestone.The scientists at Lawrence Livermore National Laboratory in California reported that they had demonstrated that laser pointers pulses shot into a cavity can produce the conditions required to trigger nuclear fusion reactions.

    optics at work... must.... find...... LASER POINTER!!! Next time, try not to scratch the lens.

    I was thinking of just the same thing with the night vision!

    exept I am not sure how easy it is to put in the ir diodes

    What I tried - just roughly - was to put all in one small tube, and it worked. For now, I don't have the complete instructable, cos I'm missing 3 components to finish the whole item/idea. I purchase 2 laser diodes (904 nm) and I want them to focus in one spot to get sufficient light source.

    another way to achieve this effect is to take out the pre-existing lens in the laser diode, harder, but cheaper.

    You are right, although ... it is not really the same - only similar. I tried 4 lenses, before publishing this instructable -> and the lens from a laser pointer was there as well (I have used it in another project called "smallest monocular") ... but I was not really happy with that results - the diameter was smaller, than by using the camera lens.  On the other side, I put the lens on the top/cover of the laser pointer ... so there could be a little bit different results, if I would place it directly on the laser mount/diode ... I will try and let know.
