When recently building my first PHR-803T laser, I noticed a distinct lack of help directly focused on how to properly solder a diode to a driver or a spring to driver- all important to properly making a laser. I think it would really help if someone could make a quick guide on how to solder...

Hi guys, Just finished up building my PHR-803t Dorcy junior build, which is all very exciting. However, so far I have managed no burning ( haven't tried much either though) and my laser emits a high pitched squeal all the time. What causes this? Problem in soldering? I'm more concerned...

Here is something cool I found while browsing on Wikipedia - A bunch of different minerals showing off their fluorescence from UV light, though some of you guys might appreciate this or find it useful ;D If you want the article, just look up UV light and it should be on the article somewhere.

So, up to today, I have noticed absolutely no mode-hopping with my X-25. Then I pointed it through a window today and the reflected beam happened to flash a foot or two to the left of my head, giving me a clear view of the beam. ( I was wearing my goggles, chill) I could not help but notice 2...

How much shock can a blu-ray diode take? I'm afraid to say I dropped my diode onto a wooden floor from about waist height...It was still wrapped in some Anti-ESD foil, but no bubble wrapping or anything.... :'( I don't have the other parts for my laser so I have no idea how to test to see if...

For my next laser project, I was kind of thinking of saving a bit of money buy using this host: http://www.dealextreme.com/details.dx/sku.12274 (Romisen 30mW). Since there is already a heat sink, for 20 bucks I get a host and heat sink, just need the Diode+ Driver ( Would I need to get an...

I am building a Dorcy Jr. Blu-Ray laser using this guide: http://www.i-hacked.com/content/view/272/94/ So I will be using a FlexiDrive from Dr Lava at 110mA, while using the flashlight as a host. Now, I noticed that the Dorcy seems to take 3.0 volt Cr123. Does this mean that I should not use...

Personally I practice Shotokan Karate. I have 4th Kyu ( Blue Belt, you start at 9th kyu and move down). I was wondering how many others out there practice any of the above martial arts. If your option isn't included, or you do any other fighting sport, feel free to leave it in a comment! And...

One of my big Christmas presents this year was one of Nova's X-series 25mW lasers. Shipping The laser was packaged very nicely. it came in a solid cardboard box, which was stuffed with bubble wrap. Then inside the bubble wrap was another paper box, in which was the aluminum case. Believe it or...

Hello LPF'ers. Canadian, but have lived in France for about 6 years now. ( slightly less than half my life). Am bilingual, french and English. Am currently learning Spanish. I own one X-25 with a 33mW avg. and 41mW peak. Will soon start building my Blu-Ray. :D

Hello fellow LPF'ers, I recently got a X-25 laser, with a 33mW avg. and 41mW peak. When doing the very few fun things you can do with such a low powered laser ( Smoking dark plastics, popping dark balloons, occasionally burning through THIN tape) I noticed that the dot was bright. Very bright...
