My 250mW 650nm popping a baloon at 4.2m

Hi! I ended changing the lens of my last red laser, I optimized it to burn at various meters of distance, the last test that I done was with a black baloon at 4.2m! And the baloon popped instantly!

Thats the coolest thing I ever done!

I think it can do the same at 5~6m, but due to the lack of space I was unabble to test it, it can light a match at ~2m, not bad (I don't know if "normal" 250mW 650nm lasers can do this without need of focusing it, only point and pop), this laser isn't focusable.

Here is my video, isn't the best, but I think is OK.

Thanks.

Wow, very nice! What exactly did you do with the lens?

I changed it, was a lens of a old Creative 20X CD-RW, now is a lens of a DVD Writer (both are good, but the lens of the DVD-RW comes with a good housing, easy to glue in place). After this, I focused it, and done!

I never seen anybody using that lens in their lasers, I think only I use it! So, I'm the pioneer!

Hehheh, yes, well no one has used them in a long time. Those results are quite impressive. :beer:
