I believe that bugs refers to only software.

I don't have a ps3. I didn't build that laser. Thats just one of them that in my collection.

Post some picts of yours smile

When I say bugs, I mean problems and things that can go wrong.

WE SEE SR'S HAND!!!!!!!!! but oh well. There is a guy on youtube with a laser pointer that can be seen on a bilbords like half a mile away....a really good laser...

Spyrorocks · Jul 02, 2008 8:07 PM

If any of you ever want to get a green high powered laser, DO NOT buy from www.wickedlasers.com. They will scam you.

dragon protector x · Jul 02, 2008 8:12 PM

ok. Lasers are fun tho. make the dogs chase them....spot on the wall shuts the birdy up....yea.

I will. In fact, when I get the time, (Either tommorow or this weekend) I'll try to put up a working demostration with my laser. I ripped up a broken PS3 and took out the diode.

Have you ever seen the old star trek phasers? I'm trying to rig up mine to work like that. Technically the laser is violet but it looks blue to me. I just got a webcam and am trying to work with it so it can produce in HD.

Spyrorocks · Jul 02, 2008 8:29 PM

Its 405nm, which is technically violet.

Because of florescence on white objects, it will appear to be blue (473nm).

405nm is a strange colour, it will do funny things to your eyes.

Did you use a driverboard when you built it, or just rigged it up to some batteries?

Spyrorocks · Jul 02, 2008 8:50 PM

Heres a little video I just made...

I generally avoid working with lasers unless I really need to.

And I handle the lasers with the power off.

bmah · Jul 02, 2008 9:13 PM

Wow. That's sweet!

Spyrorocks · Jul 02, 2008 9:19 PM

Doppel, I have full laser safety gear so its all good wink

bmah · Jul 02, 2008 9:43 PM

It blows my mind Spyrorocks that you would approach anything like that at 14 years old. At that age, I was just satisfied with Laser Tag! :S

What do your parents think of all this?

Spyrorocks · Jul 02, 2008 9:50 PM

Haha, well mostly they think it is a waste of money (My first green laser was a 95mw CNI green, which cost $200), But I don't see the problem on spending money on something that you like.

bmah · Jul 02, 2008 9:53 PM

Oh, don't worry. My main hobby of mineral collecting is VERY expensive as well. A lot of hobbies are, because often you are seeking something either expensive, rare, beautiful/aesthetic, high-quality, etc.

DragonFireOKN · Jul 03, 2008 1:10 AM

SR, sorry for not responding earlier, my dad's having surgery and I had to ride down to central VA.

For the Blu-ray laser, I simply removed the diode and welded it together with a laser container, (A round tube) Then I rigged up a battery to it and made a trigger myself.

Right now, I'm working on a laser that uses a driverboard and can project a green laser to 2 miles away. I should have it completed sometime next week. My mom works at a hospital and she sometimes brings home old computers and other machines which I can find parts in.

As soon as it's finished, I'll put up a video and upload it here. When I finish my modifications to the blu-ray pointer I should be able to put it up as well.

NEVER hook a laser diode directly up to a battery without any sort of current regulator. You will severely shorten its life and quite possibly kill it with a voltage spike.

Laser container? Do you mean housing?

What size of crystals are you using for your 2 mile green? What size of pump diode? How much output are you shooting for?

2 miles isn't that far for a properly collaminiated green or red laser.

It does have a current regulator. Although the one I'm making is a prototype.

Yes, I got it specially made to fit the diode.

2 miles is an estimate based on my math. I could have made a mistake. I'll double check. I expect a little over 550nm. I'll have to check on my crystal size, I have it written down.

Spyrorocks · Jul 03, 2008 1:33 AM

140 foot match light successful.

What size of pump diode are you going to use?

DragonFireOKN · Jul 03, 2008 1:50 AM

I don't know the exact specifications but here is the basic size: http://www.epn-online.com/lib/image.php … 193-0.jpeg

Hmmm...

Do you really know what you are getting into?

Huh? All I see is a bunch of random characters!

EDIT: Okay, I see it.

Before playing with lasers, please put the googles on, 'mkay?

Spyrorocks · Jul 03, 2008 1:59 AM

Dragonfireokn: By size I meant power output.

DragonFireOKN · Jul 03, 2008 2:13 AM

310mw (peak), I believe. I will double check on that but I'm pretty sure that is correct. It usually gets down to 205mw after it settles down.

Doppel: I've been working around lasers since I was ten. I have all the proper safety equipment.

Spyrorocks: You'll see what I can do just as soon as I can get the time to finish my emerald laser. I have a 16 page essay to write by Monday...

Spyrorocks · Jul 03, 2008 2:23 AM

What brand of safety goggles do you use?

310mW.. what an odd diode. Usually diodes are rated to the nearest 50mW. With a max efficacy of 20% conversion, you will be looking at a MAX of 60mW of 532nm. Probably lower.

What wavelength is the pump diode?
