Eating fresh pineapple daily for a few months can greatly reduce floaters.

The wavelength doesn't really matter (although a high powered CO2 laser would ionize the air along the beam's axis adding to the overall detectability) but you'll want to encode your message/ intention in binary pulses and repeat at a fixed interval.

The first number not nameable in under ten words, only needs nine words to name.

Might be able to use it before long as I've just gotten another 532nm to "experiment" with, lol.

Makes sense...thanks!

This is a video of a 532nm laser's dot on a white phone in which I place a red filter between the cam and the green dot. The red filter makes the green dot appear red. My question is: What is the source of the red laser light? https://youtu.be/LoOnOmp9J8c

Re: 1W 638nm C-Mount Laser Apparently, C-mounts require CuW onto which to be mounted. Taken from a .doc from Torrey Hills Technologies LLC Understanding of Laser, Laser diodes, Laser diode packaging and its relationship to Tungsten Copper: The laser diode is directly soldered onto the copper...

Re: 1W 638nm C-Mount Laser Here is an example of a C-mount laser diode:

Video of a red spiro I threw together in about 20 minutes.No planning involved just a couple of DC motors salvaged from cd-roms.Each wired with it's own (inadequate...way too touchy) pot with some diy mirrors made from a cd (speed control only with no reversing).I don't think it turned out too...

Thanks man! Maybe the format will catch on...seems to me that stereography and and beam shots were made for each other,lol.

Cross-Eye 3D stereogram I made with my cheap webcam.A beamshot of my first O-Like 200mW 650nm.

Thanks for the info,which I was certainly not aware,but I was just stating what the battery testing mode of my meter reads for two rechargable CR2s tested separately without a load.

Alright,here is a link to a photo of the multi-meter I have.At the upper-right hand side is the mode select position which states 1.5v(4.0mA) 9v(25mA) http://i190.photobucket.com/albums/z109/rgcurro_2007/DIGITAL/MULTIMETER-2.jpg?t=1280284449

Those measurements were taken using the "battery testing" mode of my meter where a fresh 1.5v battery would measure 4.0 mA or a fresh 9v would measure 25 mA.
