I got my 1.8W the other day. Great laser, and while I don't have a meter to test the output power it will light a sheet of white printer paper up in 20 seconds and burn a hole through a black cardboard box in 10 seconds from close range.
+1 to Grix's service, too. There was some confusion with my address (he sent it to the right address but in the US instead of Canada), and as soon as he realized it he sent out a new laser, along with a couple batteries to compensate for the delay and my not being able to run it (I'm using 18650s instead of CR123As). Both packages actually arrived at about the same time, but great service by Grix.
Thanks for the positive review! I try my best to make every customer happy, even when mistakes happen  1300mW lasers are now in stock, and the 1800mW model should be in stock within 2-5 days! When the 1800mW gets back in stock, it will be in a new body with better cooling capacity, yet the price will decrease $20, to $239! Some technical trouble, might be a while before the new model is in stock. A current-style 1800mW is on the way, though. And remember, if you buy something from bitbrew.net and use the discount coupon, you can save even more (even counting the cost of the delicious coffee)! |

Please don't let this affect Bitcoin Magazine. The magazine itself is an excellent contribution to the community and huge advertising for bitcoin. Don't let one person's mistakes ruin the whole thing. I'm sure Vladimir will exclude Matthew from any further involvement.

A lot of news: We've entered a cross promotion with Bitbrew.net: https://bitcointalk.org/index.php?topic=104688 The 1300mW blue laser has been renamed for the occasion  . The next two will have a free copper heatsink upgrade. Other news include four new products: - 50mW Green Laser
- 50mW Violet Laser
- Flash Paper
- Smoke Cartidges
Many lasers and items are now in stock after a long delay in restocking. In the near future we will release a new kickass laser: A very powerful 635nm Orange-Red laser, around 7-800mW! The price will be in the neighborhood of $199. And lastly, the 1800mW Blue lasers will get a redesign soon, with better cooling AND lower cost! |

I'm happy to announce that BitBrew.net and BitLasers.com are now running a cross promotion! When ordering from one, you'll get a 10% discount coupon for the other! To celebrate, Bitlasers is renaming the bestseller 1300mW Blue laser to "The BitBrew", and for the next two orders, the laser will be shipped with a copper heatsink instead of aluminium providing better cooling and duty cycle for no extra charge. We're also adding a variety of new products, like a line of new, cheap(er) lasers and some fun accessories. Bitbrew will be launching a new coffee blend, I've been told it's "A full bodied Italian roast with a smokey taste and mild acidity". Bitbrew has been around for a long time, and I'm very glad to be able to collaborate with edd. |

Hm, yes, that looks very cool. I'll definitely consider it for the eventual next order.

I haven't quite decided on a battery yet, but I think it'll be a 11V ~2500mAh battery which will provide about 10-20 minutes flight time depending on how hard you drive it.
Try 8 minutes. MAYBE. No way you will be getting 20 minutes on a quad with a 2500mah lipo. Here are the questions that need answering What do you plan on using for an Flight Control Board? Which esc, motors and prop sizes? Will rc control tx/rx be included? What frame will you be using? I think you are new to building multi rotors.. There is a lot more to it. You need to get the correct ESC (electronic speed controllers) for multirotors and repflash them if necessary , the correct motors for the application and the correct prop size for the motor/frame. Under propping or over propping will cook the motors. the you need to know how to program the ESC's so when they hit the low voltage setting they wont kill the motors and drop your quad out of the sky.. I have a self-built quad myself with mostly the same parts as this, it works great. I know how to build them. I was going to post full specs and documentation when I got the parts, I didn't know exactly what I was going to buy until yesterday. >What do you plan on using for an Flight Control Board? Hobbyking v2.1 with the newest KK 4X firmware flashed. >Which esc, motors and prop sizes? Turnigy Plush 30A, NTM Prop Drive 28-26A 1200kv / 250w, manually balanced 10/45 molded props. >Will rc control tx/rx be included? Yes, as said. The hobbyking HK6S, 6ch, 2.4GHz. >What frame will you be using? Hobbyking SK450, glass fiber, 450mm. |

Well, I've ordered parts for one all-you-need kit. If it sells fast I'll order several more. If more than one is positive that they want a kit, you can preorder with a partial payment and I'll order more right away.

I think the price is still quite good considering the assembling and adjusting I'll do. As I said you could get a copter for cheaper, but mostly in fully DIY packages without any service. And yes, I will provide assistance if any of the customers ever need it. It will not be hard to repair at all, and I have spare parts at home that I can send asap if needed. It's electric, afaik the majority of quadcopters are electric. It's more convenient imo. I haven't quite decided on a battery yet, but I think it'll be a 11V ~2500mAh battery which will provide about 10-20 minutes flight time depending on how hard you drive it. Anyways I think I'll order a set later today. I figure the worst that can happen is that no one buys it unless I sell at a loss, but whatever. At least I'll learn something Things might get a little bit more expensive than I anticipated.. What is the highest price you guys would be willing to pay for these kits? I can do $350 + shipping for a complete set with everything you need, or $320 for the copter alone, and I won't even be making that much profit. Is there still interest at those prices?
Also, are you guys more interested in the only-copter solution or the all-you-need solution?
ok so I am interested in learning about quad-copters but know nothing about the regular prices. You tell me if this is a good deal or not One disadvantage I see is if you do all the work, how would I know how to repair it (re-balancing the propellers?) and which tools I need for that. Will you provide customer support? Is this electric or gas? What is the range / flight time? I'm leaning toward looking for a gas one because I'm worried about it taking longer to charge up the battery than it runs for. |

Ok, I'll likely buy parts for one copter very soon, probably tomorrow, and we'll see what happens next. If it indeed sells quickly I'll probably buy more |

I'm considering expanding my bitcoin business to something other than just lasers, and I was thinking Quad copters would be an ideal gadget to sell! Quad copters are RC helicopters with four different horizontal propellers. Quad copters are very fun to play with, and they are surprisingly strong. These copters should be able to carry at least a load of .5-1 kilogram, more than enough to for example mount a camera to it! They are also relatively easy to fly. Although one will probably break a few propellers during the first few flights, after a while it will be very smooth and simple. The parts I will choose are made of high quality material and are sturdy and light. Some features it'll include are automatic gyro-stabilization, low battery indicator, etc. etc. Although I obviously cannot beat the cost of buying individual components from asia, what I am selling is my knowledge and labour, not the parts. Researching and building a quad copter from scratch can be a daunting task for most people, therefore I was thinking of offering kits where all the hard work is already done by me so that you just have to screw a few pieces together and start flying! I will be soldering the wires, setting the control board properly, balancing the propellers, and all the other things that require special tools, time and know-how. If my calculations are correct, I think I'll be able to offer a very competitive pricing as well, something like $280 for the quad copter alone and maybe $330 for everything you will need such as the radio, battery charger, spare propellers and so on. (Note that this does not include shipping which would be around $25 to europe and $40 worldwide). So I'm just wondering, are there interest for this in the bitcoin community? The kits are kind of expensive so I don't want to order some if I'm not positive I'll be able to sell them at all. Perhaps I can do on-demand ordering, but I doubt anyone would want that because of the extra long shipping times. Here are some videos of quad copters in action (Not my specific build though): www.youtube.com/watch?v=bsrzBwylodUwww.youtube.com/watch?v=xPcYI7gk6r4 |

I've spent hundreds of dollars on that site the last few years.. For them to accept bitcoin would be huge, but I'm a bit pessimistic about this. Perhaps we should focus on smaller websites first.

Have you done any builds with Nichia diodes?
Nah, I haven't. Their diodes are kind of expensive and they don't really fill any role that other diodes can do just as good. The exception are the exotic wavelengths, but they are hundreds of dollars for a single diode for now..  Though there are one diode that I would like to build something with once, the Nichia NDB7875 (at least the laser community thinks that's what it is), should be able to produce at least ~2200 mW of blue, but again, it's expensive. The whole laser would probably be over $300, I don't know if there is any interest for that.. |

Another bump! We have more lasers incoming, including the 1800mW beast, and some cheaper lasers such as a 50mW green and violet. Both will probably be priced at around $45. And as always, if you want a kind of laser that is not listed or that is out of stock, you can contact us for a custom order at gitlem@lavabit.com . |

There's one issue with their stance though, and that it that the EFF article they link to are over a year old, from around the time of the bubble last year. How much time will have to pass before they are comfortable with bitcoin's legal status? With this pace it'll be years until that time..

Drugs are one thing, but sending illegal firearms in the mail is a whole other league of risky. I don't think the Armory will be missed that much.
