Well it's stuck, I can't remove it or press it, so I'll have to stick with this I guess.

No, the head just doesn't want to fully screw on, the heatsink seems to long, but I think it's the brass ring that's stuck mid-way into the pill. As for the battery, it's just to tick for the barrel, so I used jumpers for the tests.

I'd like one too.

Received the package today, and well, it's done! But I'm missing the proper battery, I used a RC2 from DX that doesn't fit in the barrel (almost) to test and set the current.

Received my package today, and everything works. Thanks Glenn.

Cool, and they even say the got near TEM00 beam specs. This could really be worth it.

I've been using a very small aluminum tube I had found at hardware store (no idea what it was supposed to be), and though it has collapsed (because a part of the wall was thinner), it still works well.

We have a microscope thread??? Anyway, that's a cool simple DIY microscope!

Woah, that's really cool! I wonder what's making it glow like that... Maybe the yellow pigment, or the alcohol...

Well maybe Daguin or some other forum builders have some fully assembled lasers for sale. Edit : here's a link to the 18650 kit http://laserpointerforums.com/f64/fs-18650-build-kit-easy-assembly-445nm-blu-ray-red-43857.html

Get yourself a 18650 (did I get the number right?) kit from Jayrob with full copper heatsink and "hot option" (if you never built a laser before) and take a look in the Group Buy section of the forum for good deals on these diodes.

This is just a regular Casio projector diode, nothing special there. You can get them cheaper in the GB section.

Could you please post a link? Because this sounds really weird : argon lasers use gas, yet you are also talking about DPSS (IR diode pumped crystals) and diode. This is IMO a 488nm DPSS laser, but at 1W??? Not sure about this...

Found this one on a couch at a home I'm renting this summer : It took me by surprise when it jumped on my lens... So I brought it outside : Haven't yet edited these images, this is raw camera output.

I think they are pulsed... But that's for projector use.

Me too, I'm in! I got a 445nm diode on the way, a flexdrive, an aixiz glass lens, and I do have building experience. Plus I got a great camera and macro lens. :D

Awesome, a new contest! :D I'll start working on one very soon...

Well I finally found a way to delete the bad marker. Everything is OK now. Thanks anyway.

But I hate pie.... :( Here's some rare sea birds I spoted today... a Plover : an adult tern : tern chicks :
