A FREE sample? lol A half watt is too sweet an idea, but not for my $$$$$. Unless it can be had for $500 or less.

Re: Using keychain red laser driver w/ these diode Sorry for the pathetic post. Just out of the 100 or so cheap pointers I trashed, none had pots. As far as the IR laser I too have wondered about this as I now have several "chip" style ones and thought about making a laser assembly by stacking...

video : If I were to use this, which I might, I would get the dollar store, most transparent, mirrored front glasses, then put this behind them on the lenses. EDIT focus is at infinity lol i have no sleep for 26 hours now TIME FOR BED Video was not as dark b4 upload sorry

Someone send me a meter and I will be happy to test this stuff.  ;D LOL J/K But as far as that goes if someone wants to use this stuff fine, better than nothing. With my tests so far I have found a few that show nothing, no dot, nada. And here's the one below 0%transmission around 620-645nm...

Yep your good on heat sinking, and where did you find the Coleman? My Wal-Mart has a silver one that runs on 2 cr2 batteries and I am looking for that one.

I think I will email them back with the prices for a 6x diode from here, and a 803t...

There are several other colors that block these colors, one blocks under 0% I will post pics of these soon and thank you for the rep.

Ha, $1500 for an 85mw blue-violet Sanyo diode!

After some more testing I would say these would be ok for friends watching from a distance. 5 feet + http://www.barbizon.com/catalog/index.cfm?Series=2&brand=37&BrandTitle=Gels%2FFilters%20in%20Sheets  gels in sheets congo blue is #382 trans. .56% data: I changed my tune because all original...

Ok so I have some Ideas time to post them: 1: A heat sink made from an old P1 heat sink by drilling a 1/2 inch hole centered on the mating surface w/fan 2:Thermal epoxy by mixing epoxy and Arctic Silver 5 (gotta test if it conducts electricity when cured) 3: Applying some sort of Heat sinking...

No problem man, from the reading I have done at 420ma we are getting closer to 300mw of power. It does need good heat sinking at this level but with a 1 inch cube ALU heat sink I run mine for a few minutes with no problems (knock on wood). If I should not do this someone please stop me!

I have been thinking of gels for a while as I have one of those theater gel sample packs with 1000 or so samples in all different colors, with nifty little papers that show what wavelength they block. So I tried it with the lowest blocking filter (double blue I think .5% transparency, congo blue...

Re: Using keychain red laser driver w/ these diode Weird I've not found a cheap keychain laser with a pot yet.

Get a Fluke... LOL... they are overpriced as heck. Mine was a gift, but If I was to buy one I like the Eclipse 400-047.

Thanks, figured they were high end. [smiley=sad.gif] Oh well maybe they will send a few goodies still.

http://www.photonic-products.com/index.html They have all kinds of diodes and other cool laser stuff too.. Just realized I should have put this in companies. Oh well

Yes the dummy is necessary, to tell the correct mA at the correct voltage of the laser. this thread explains more: http://www.laserpointerforums.com/forums/YaBB.pl?num=1197651171 If you don't use the load the mA will not show right, and the voltage is weird too.

No problem, this diode is POWERFUL!  ;)

Re: Finally done it (I killed it by sneezing) Thanks for the tip, I got rid of the pot though and have new diodes so I am back in business YEAH! Microdrive @ 420ma on a 22x lg long open can! 16x on DDL home built driver @ 250ma!
