Alright, I'll bite, I'm a sucker for laser gadgets.

Order placed, discount applied, bitcoins sent.  Will report back if/when the device arrives and if it hits their specs after testing.

-X

Yay, the unit finally arrived.  Well packaged, well put together, this thing is ridiculously bright.

One note, the sale if just for the base unit, you will need a couple of CR123A batteries and a set of appropriate safety glasses on hand.

Good seller, I am satisfied with the transaction!

-X

Thanks a lot for your feedback! Smiley

Prices on 635nm (orange-red) and 405nm (violet) lasers have been decreased from $199 to $159 and $165 respectively. I just want them gone since the blue one seems to be much more popular Smiley


get a focusable 100mw or more green laser!

It's already on the way.

Any plans to sell parts? I've built a couple of these, need to replace the driver in one of them.

Sorry. I figured, while lasers for bitcoin is niche enough, parts for lasers for bitcoin would just be downright impossible to run a shop with Smiley

HOLY SHIT A FUCKING HANDHELD YELLOW ONE?!?!!
BUY
BUY
BUY
BUY
MUST BUY WITH BITCOINS
MUST BUY YELLOW HANDHELD LEGAL LAZER!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Yellow lasers cost hundreds of dollars for a few milliwatts.

Also, a new red diode seem to have been discovered out of nowhere. Testing is being done, but if we're lucky we will be able to see ~400 mW of 660nm red for pretty cheap ( like $90 ). A lot of exciting stuff happening in the laser scene now!
Wow nice, what product might that have been initially designed for?



I don't know.. The diode wasn't extracted from a device, but someone got it directly from a supplier/manufacturer which he hasn't named yet. It's possible it would be used in very high speed DVD recorders or pico video projectors.

Some updates:

One of my major suppliers have closed their business, so I'll have a little delay on the new blue's. I should have enough parts to make one of them any day now, but the other will be at least another week away.

Thanks for the support, guys, I really appreciate it! I'm still waiting for parts for various lasers including two blue ones. But remember, I still got a sweet red and violet one in stock, no love for them? Smiley

I should get a news module or something installed so I can easily show the status on incoming items on the store.

It's not a secret that lasers like these are regulated in some countries. The buyer has the responsibility to check their local laws, if they order to a country where it's illegal, that's their risk.

That being said, I don't ship from a country known to export lasers, I mark the lasers as flashlights, they look like flashlights (and technically lasers are a kind of flashlight, portable light source), and I offer to ship the tailcap and batteries in a separate package to prevent customs from testing it if they actually do inspect the package. So if someone does order a product despite the legal status in their particular country, the chances of customs busting the package are very slim. And even if they DO bust the package, I'm pretty sure that person won't get in any legal trouble, they'd just return the package to sender. At least that's what my country does to gray-area items.

I’m in the USA and my mommy government doesn’t want me to be in control of my life (they’re illegal). Can you ship the laser in multiple parts in different packages so customs will pass it through? If yes, how much extra does it cost? I’ve already had one Dragon Laser confiscated by customs during shipping and it kind of sucks losing that much money.

I've got all the info you need on my site under shipping information:

I mark the item as flashlight, and it does look like a flashlight on x-rays (because it is built inside a flashlight shell). You can also buy batteries separately or elsewhere, then the customs don't have a way to test the laser (I don't think customs keep CR123a batteries handy).. I can ship the tailcap separately as well, but that would of course cost a little more in shipment.

I'd be interested in a green laser that's better than 5mW, but not so powerful that the reflections off of dust particles fuck you up.  
 
My 5mW green I use for star pointing, but if there's not much dust in the air, people nearby have problems seeing unless they're closer to me.  But what I don't know is what the "limit" would be so that if I accidentally caught the reflection off like a sign or something that it also wouldn't fuck my shit up.
 
Whatever that value of X is to be as bright as possible w/out fucking my shit up on stupid reflections, that's the green laser I want. Smiley  Now I understand that staring at it would be bad, but like soon as I see it have time to turn away/blink.  What power green would that be?

I've heard about 75mW is perfect for star pointing. Very bright beam but not bright enough to reduce your night vision. You shouldn't really worry about reflections unless you are using hundreds of milliwatts or the reflective surface is very close and very reflective (like a mirror), only a direct hit should be any concern.

Cutting stuff ftw! I wonder how it'll do against the tires of a car ...l Tongue

Uh that's just video editing... Undecided

No shit, sherlock, it's just a joke Smiley


Also, good news: I've ordered parts for two more blue 1.3W lasers, and a 100mW green one. They should arrive within a week, two weeks max, but you never know with the postal service..

I'm also investigating how to offer a reliable 1.8-2W laser, because of the interest. I'd have to use a different host because it would need better heatsinking, and I'm not sure of the batteries either. Some CR123s can't handle the current draw. I'll get back to you guys.

When will you have lasers in other price ranges in stock? Also what other styles of lasers can we expect and by when. You have some very cool stuff. I'd be interested in things in the 160$ price area.  Thanks!

Read the thread, hehe, I think I've answered that at least three times Smiley

Yes, there will be more laser in the catalog soon, including green lasers in various powers, weaker red and violet lasers, and possibly a more powerful blue laser. tl;dr: a bunch of more lasers.
455  Economy / Service Announcements / Re: BitLasers.com - Handheld Lasers and accessories on: April 16, 2012, 07:50:00 PM
How wide can the beam be spread with the included lens?
Also, how about a green laser that will work as a pointer for a presentation, so isn't dangerous, but is brighter than the usual stuff?

You can unscrew the lens completely, which will make the beam as wide as a regular flashlight (Over 1 meter diameter dot a few meters away).

I will order green lasers in various powers very soon.

I noticed that the wickedlaser pointers claim that they can stay on continuously without you worrying about overheating. Do they just have a badass heatsink on them?

Their spyder III series is massive, yes, but I think the most important factor is that they have set the current quite low on purpose to avoid lasers breaking. In others words, the diodes in their lasers could potentially produce much more power, but then they would also produce more heat.
456  Economy / Service Announcements / Re: BitLasers.com - Handheld Lasers and accessories on: April 16, 2012, 05:55:10 PM
Violet lasers can detect UV-sensitive markings (invisible pens for example)

Yay, I can read the invisible ink for a fraction of a second before the paper catches fire (assuming the violet ones are as powerful as the others) Smiley

You can unfocus the laser until it becomes no more dangerous than a flashlight, hehe
457  Economy / Service Announcements / Re: BitLasers.com - Handheld Lasers and accessories on: April 16, 2012, 04:10:29 PM
They look very cool. But what are they intended to be used for? They are definitively too strong for playing around and too weak to cut materials. I am sure there are billions of other uses for lasers but right now none comes to my mind. So a round of question to the interested parties: what would you use yours for?


It's hard to explain, things don't have to have a practical use to have a value. I know I said in my first post that lasers are not toys, but then again, maybe they are toys for grownups. The magnificent beam in the night sky is a sight that always makes me gape in awe. And the gadget factor is just enormous Smiley

Though they do have some actual applications:

Astronomy (Pointing out stars)
Aligning stuff
Signaling
Long range illumination
Violet lasers can detect UV-sensitive markings (invisible pens for example)
Creating fire

Those look pretty awesome, how much will you be selling the blue lasers for?

The one I offered when I lauched the website was $189. I wish there was a way to display sold out items and their price on the website in a non-clumsy way, but I haven't found one yet.

I'm drooling at the 2.2w blue laser by survival lasers here : http://www.survivallaser.com/Survival_Laser_II_Special_Edition_445nm_Parts_Bundle_Laser_Components_Only/p556088_5173902.aspx

Any chances of doing something high powered like that? Grin

He's got a little more resources than me, so what he has done is bought a bunch of diodes and cherry picked the most efficient ones, but diodes are expensive, so I doubt I'll reach those powers any time soon. But as said above, 1.8W should be doable, and for much cheaper than the survival laser one. Smiley

That being said, there is a new type of blue diode being researched by the community as we speak, discovered in a movie projector. If that turns out to be more powerful than the current diodes in circulation, maybe we will see >2W lasers soon after all!


Price is no issue for me, so long as it's reasonable for the hardware, labor invested, and such. That all being said, if I see some good feedback on your previous orders, would you by chance be willing to build one custom for me? Perhaps a 2W blue 445nm, before you are offering them to the general public? I suppose that might be asking a bit much, but if not, I can certainly wait until you stock them.

Yes, I could do that, but as said I don't really have the money to buy too much stock, so by offering it to you exclusively I'd also have to make the others that might want one wait longer for me to restock, so I think putting it on the website, then first come first serve, would be more fair.
459  Economy / Service Announcements / Re: BitLasers.com - Handheld Lasers and accessories on: April 16, 2012, 05:43:34 AM
Is it possible to build more powerful handheld lasers? Perhaps a 2w model?
In all honesty, I would like the beefiest laser possible, so I can use it to cut materials like wood, plastic, fabric, etc...

I'm reading here that the violet laser is a single mode, meaning you can focus the laser into a very small point... Are there laser-builds possible that utilize more milliwattage, but still have that feature?


Yes, higher powered lasers than what I sell is possible, either by increasing current alone (But that would shorten lifetime and duty cycles, so I'm not going to do that), or upgrading components like the heatsink to allow a little higher current, and a high-efficiency lens. But that would of course increase the cost, lenses alone can be quite expensive.

The higher single mode would have to be a violet one, they could potentionally go close to 1W.. But the best for burning is still blue 445nm just because of the sheer power. As said above, a 1800-2000mW laser is doable, and I think I will sell them in the future sometime. (Not cheap though, just saying. It would cost at least $250).

They are T-rex branded, my supplier states these specs:

Quote
Visible Light Penetrated Ratio: >55%

Optical Density: >5.0(OD+5,OD+6)

Attenuation Ratio: 10-6

I test every pair before I sell them to ensure adequate quality.
