[US-CA][H] 5+GHs Bitcoin Miner (BFL Jalapeno) [W] Bitcoins or Paypal

Hey!
I have a Bitcoin miner that I'd be willing to part with. I want to sell this model of Bitcoin miner. It is plug in and play, just grab the software/drivers from the Butterfly Labs Website and you will be making Bitcoins in no time. The miner only has about a month of wear. It will not be shipping with a PSU however, as I need it's PSU for another miner, but it just takes a standard 13V/6A DC PSU. I'm looking for ~40$ plus shipping. The miner tends to mine between 5 and 7 GHs.

A Look at the BFL Jalapeno and Little Single ASIC Bitcoin Miners

submitted by bitterone65 to Bitcoin [link] [comments]

Will my BFL Jalapeno be worthless by the time it arrives?

The difficulty is sky-rocketing. My order was made in July this year. It feels like a waste of money now.
Anything to make me feel better?

The $22,484.00 Butterfly Labs Mini Rig bitcoin miner is a huge, broken, unstable piece of shit.

(This was a rather controversial article posted on Buttcoin.org and became quite popular, even moving to the top of /bitcoin. It's since been mysteriously edited on the site [maybe by g-g-g-ghosts!] so it's being reposted here for posterity's sake. Some numbers may be off by now, but it was all accurate at the time of posting.)
Butterfly Labs has a long and horrible history with their mining rigs. They started taking pre-orders over a year ago, with a ship time sometime in late July. After numerous delays in production, shipping problems and general incompetence, the only thing they’ve managed to get out the door are some of their tiniest miners, the Jalapenos. And those mainly ended up in the hands of reviewers and blogs in order to keep pumping the Butterfly Labs hype train and securing millions of dollars of pre-orders still in limbo.Lucky BFL forums user Luke-JR however scored a sweet Mini Rig from Butterfly Labs (it’s just a coincidence he’s a driver developer for them I’m sure). This rig was originally promised to produce 1500 GH/s hashing power at 1500 watts for $30,000, but has since seen it’s hashing power slashed to a third of what was promised and it’s power consumption increased 75%, now just offer 500 GH/s at 2400 watts. They’ve promised to make good on pre-order buy sending out 3 rigs to match the initial hashing rate, so now it’s only 1500 GH/s at 6900 watts, a reduction in GH/Watt by a factor of 5.
So what does $22,484 buy you? Take a look!
Minirig is here! Today, my Minirig arrived.

FedEx apparently dropped it somewhere along the way, and the weakest part of the case, the thin metal part around the back of the PSU, broke.
http://i.imgur.com/lFcOHxP.jpg
I’m not sure how sturdy the back side was supposed to be, but its two pieces aren’t quite together either.
http://i.imgur.com/AVttcOt.jpg
The power supplies (EVGA 1500W) also created havoc interfering with the neutral on the power line. This disrupted X10 communication significantly enough that the pool overflowed because the system controlling it was unable to turn off the pump. Workaround: This PSU supports 240V, so we rewired the outlet. 240V does not use neutral, so now all should be okay.
Edit: 240V workaround is only partial. Still having problems
But the good news is, it all seems to be working for the most part.
Next up, installing it in the window so the heat goes outside
A twenty two thousand dollar box of electronics that is broken out of the box, that required the guy to do a sketchy electrical workaround to get partially working, that he is going to install in a window… and he’s happy about it?
In case you didn’t notice it, the delivered unit is different than the picture on the website. They had to install 2 power supplies instead of 1 and had to modify the case to fit. Also, if you didn’t notice, the LCD/Phone thingy in the front has been replaced by … a piece of cardboard spray painted black. Wonderful.
You could maybe chalk this up to a careless Fedex postman, but when you’re shipping something that costs as much as a mid-sized sedan, how bought putting a little more effort into packing? Dell and HP can ship bigger and heavier servers across the world without this kind of problem.
The unit had to hit its huge power draw increase by putting dual EVGA consumer grade power supplies in the unit. We’re talking almost a 75 amp load (6*1500/120), disregarding power factor. He could very well overload the circuit panel and trip the main breaker for the house.
Let’s take a look inside this guy.
This is from an earlier version of the Minirig (note the single power supply) This is apparently from an earlier FPGA but it will give you a good glimpse at what kind of craftsmanship you can expect from a computer that is half the average household income in the United States.
Consumer grade PSU and cheap USB hubs glued to the inside case.
Electrical tape and random velcro glued to the insides
A closer look at the USB hubs. Plugs are hot glued to stay secured.
Electrical tape everywhere, splices and voided hardware are the theme.
You can view the entire album here.
Despite all that, this thing can still mine bitcoins and it should be profitable. Keep in ind that many people jumped in on the preorders a year ago when bitcoins were still hovering around $6.50 per. Meaning customers paid 1562 bitcoins for that particular piece of shit, which at today’s value is $156,200. Aston martin money. How long will it take them to make their money back (as apposed to just hanging on to them)? If the difficulty didn’t change, they would make 37 bitcoins a day and recoup the initial investment in 124 days. Difficulty is jumping pretty much 20% every 12 days or so, so in the next week before adjustment, they’ll make 259, the next 12 days 369, the next 12 days 312, then 256, then 213, etc.
So by day 127, they’ll be halfway to breaking even, but by day 151 they’ll be making less than 5 bitcoins a day, and even if difficulty stopped rising at that point(which it won’t), it would take another 435 days for a total of 586 days to break even. If difficulty kept rising at the same pace, by day 200 they’d be making 2.4 bitcoins per day, and it would take 1024 days to break even with no difficulty increase. Assuming 25 cents per kw/h, and $100 a bitcoin, it would cost 0.43 of a bitcoin per day in electricity which means the unit would no longer be profitable on a power usage basis by day 307, at which point it will have produced 2620 bitcoins.
Bear in mind this is only for the first few units, and that’s running 24/7 pumping out around 24,000 BTU, so yes, medical bills from heat stroke will be on top of that.
But Alas, the chips don’t run nearly as well as they’re supposed to, frequently running too hot and giving multiple hardware failures. Coindesk noted in one of the first ever runs of the Minirig by hosting provide gigavps that it was running much too hot and erroring out.
At the time of posting, gigavps warned that the unit would be repeatedly shut down while ckolivas, who was assisting, modified the machine’s software to optimise performance. After some tweaking, the device was said to have been left to run continuously for two hours, and was shown to have an average hash rate of 478.1 GH/s. As you can see in the table below, ASIC number four (of a total of eight hashing chips) ran significantly hotter (86 degrees) and consequently gave the highest hardware (HW) error rate.
http://i.imgur.com/q3iGrnb.jpg
So, what happens if you just decide you don’t want this, you don’t want to wait over a year to get a $22,000 broken piece of shit? Nothing, because BFL won’t let you cancel your preorder because they’re now “shipping”, i.e. they sent out one unit to their own company shill.
http://i.imgur.com/0p3Up03.jpg
Which is of course illegal regardless of what Butterfly Labs may say.
So in summary: Don’t buy anything from Butterfly Labs … ever.

Is all mining now negative return-on-investment?

I have been closely watching the mining scene for only about 3 months, so excuse me if this sort of question is asked frequently, or is too speculative.
Is all BTC mining now underwater, with a negative ROI?
That's what it looks like to me. I initially got interested years ago, when the return was small and BTC was not worth much. I didn't mine because it seemed like a miniscule return on investment. Oh I wish I had started back then, those "worthless" BTCs would be worth a lot now.
But I started getting more interested again when that Ars Technica article on the BFL Jalapeno appeared. Holy crap, a machine that prints free money. He made hundreds of bucks in a week.
So I started checking it out. With the delays in BFL's product shipping, all the mining calculators show that any new investment in mining hardware will never break even. Difficulty is increasing so fast, that the only machines making money are already in place, and soon they won't even pay for the cost of electricity.
Now just to screw this up even further, BFL did a classic "Osborne Effect" announcement of their new Monarch board. Their existing ASIC machines are obsolete. The new 28nm machine that does not exist yet, is promised to deliver 600Gh for 350 watts, and costs $4680. I ran the numbers through the mining calculator at The Genesis Block. Unfortunately their calculator seems to be down at the moment, but I recall running numbers on a Monarch, delivered even in December, would not break even unless BTC went up to 2000 per dollar!
Now even accounting for BFL's broken promises, if I could buy mining hardware like this today and turn it on now, it would make a negative ROI. I run the numbers for every possible hardware I could buy, none of them are as cheap in dollars/Gh or Gh/watt as the Monarch. And none of them break even.
I decided to track the existing performance of mining using my dinky Mac mini's GPU. It won't mine much, and GPU mining will never break even in a network full of ASICs. But it would give a rough index of how difficulty is affecting mining. Here's a rough description of my results. At this point, it looks like mining is doubling in difficulty every month. Nobody can make money unless either BTC rises in value dramatically, or the majority of miners give up and unplug their unprofitable mining hardware.
So someone tell me if this assessment is realistic or not. At the moment, it looks like any new investment in mining hardware will result in turning every dollar of investment into 50 cents worth of BTC at most. With increasing difficulty, soon even existing mining hardware will be turning every dollar of electricity into less than a dollar worth of BTC. ROI is underwater now for new hardware, and soon will be underwater for all hardware, even advanced ASICs that haven't even shipped yet. There are only two ways that mining might ever make a profit. One is if almost everyone gives up when their miners become unprofitable. The other is if BTC goes up massively in value to like $2500/USD, which will only fuel the arms race even more.
Yeah, I know there is a big incentive to spread disinformation to convince people to drop out of mining. So don't try to BS me. Let me hear your honest assessments, or please point me in a direction where I can do research to figure this out.

Frequently Asked Question: What's an ASIC, FPGA?

So you're sick of just mining on your GPU, and not a fan of the electric bill after a month of mining? There has to be a better option out there than your loud GPU in your gaming computer. There is!
Shortly after GPUs became popular for bitcoin mining, enterprising folks started looking at other things they can re-purpose to mine bitcoins more efficiently. Around mid-year 2011, the first devices sprang up that are called FPGAs or Field Programmable Gate Arrays. These are nothing new to the hobbyist community, they've been around for a while for crackers and other security-conscious folks looking at ways to defeat cryptographic locks. Hey! I know something that uses cryptographic calculations to secure its network! BITCOINS! Yep, so some miners developed their own boards and slapped some FPGA chips on them (most commonly the Spartan-6), and wrote specific firmware and "bitstreams" to more efficiently calculate bitcoin hashes. The first generations were sort of slow, but still they had better efficiency than a GPU. Some of the latest generation included the Icarus boards, Cairnsmore, x6500, and ModMiner Quad.
In early 2012(i think my timeline is right), Butterfly Labs(BFL) was selling their own FPGA miner that hashed at 800 Mhash/s using 80 watts and only cost US$600 amazing! These grew very popular, but people could see that FPGAs still weren't the most efficient way to hash their shares. BFL then announced that they would be designing their own chips that would be orders of magnitude faster than anything ever seen. These would be the ASICs (or Application Specific Integrated Circuit)everyone is raving about. ASICs are--as the name implies--specifically designed for one thing, and one thing only. Bitcoins. This is all it can do, and can't really be repurposed like an FPGA to other applications. Who wouldn't want a US$150 "Jalapeno" that hashes at 3.5 GIGAhashes/s using only power from a USB port?? Crazy! So summer 2012, BFL says they will ship before Christmas. Various things happen and we now still don't have any confirmed ship dates from BFL.
A few other companies have sprouted up, ASICminer which I believe is developing their own chips to mine themselves, but in a responsible way as to not threaten the network with a sudden influx of hashing. bASIC was a fiasco that was developed by the creator of the ModMiner Quad(which is actually a fantastic miner, I own one, and love it.) where he took many preorders, promised lots of people amazing ASIC performance, but in early 2013 the stress of the whole endeavour got to him and he gave up, refunded money(I think it's still being refunded now, or maybe it's been cleared up already.)
Avalon is the only company we know has ASIC mining hardware in the wild. It is not certain exactly how many are out there, but they have been confirmed by independent sources. The Avalon units are expensive(75 BTC) and have been in limited production runs (or batches) of a few hundred units that were pre-sold out very quickly.
All of this info is gleaned from the Custom Hardware forum over at bitcointalk.org over the past year or so I've been involved in bitcoin. I may have some facts wrong, but this is the gist of the situation and hopefully gives you an insight on the state of the hardware war against bitcoin
Thanks for reading!

BFL Labs - What I know so far

Hey guys,
Not sure if you are aware, but Josh from BFL labs has advised units to begin shipping end of april. (Hopefully)
https://forums.butterflylabs.com/announcements/692-bfl-asic-status-3.html
There have been further annoucements and talk in the shoutbox regarding this.. information seems to be all over the place. so this is what I know so far:
18/04/13: At this stage they are in the final stage of testing and fine tuning the power consumption ( predictions showed it to be in the range of 1GH/J but its now looking closer to 170MH/J ) This will also likely improve over time but is still miles ahead of Avalon and GPU miners.
Minirig is no longer available for purchase as they cannot fit it in the case that it was intended for so after the Single SC is finished they will look into the minirig again, But the minirig is composed of Single SC's that are running on a higher clock due to more optimised cooling.
The chips are FINE. The delay is re-engeneering the power system on the boards to handle to extra consumption.
IMHO I think they will start the shipping process on end of april, They will start with the Jalapeno's and work their way up. Still no ETA for minirig though..
You may have heard about the tour on reddit http://www.reddit.com/Bitcoin/comments/1c3hyc/toured_butterflylabs_a_few_hours_ago/
This was confirmed by Josh but he also made a valid point, "Why would we pay staff to stand around watching" Once the shipping process begins they expect to ship 400 units per day. I would say the first week would be 200 units per day average while they sort out all the kinks. But I have high hopes.
UPDATE: Photos of Mini-Rig: http://imgur.com/a/Uanjr#0 Please note these may be an older model, But give you a better idea of how a slightly larger PCB will affect the production..
If you have ordered from BFL Labs, Please fill in your details here so we can publicly track how many have been delivered etc.
UPDATE 2: Found this on BFL website.
BFL will make 400 units/day. 2,000 units/week. 8,000 units/month. That means: ->4 months = 32,000 units ->5 months = 40,000 units ->6 months = 48,000 units
UPDATE 3: There are many photos and some misc information on BFL and the ASIC miners below. Forum registration is required for some photos. https://forums.butterflylabs.com/bfl-forum-miscellaneous/1099-orders-shipping-pictures-facility-when-my-stuff-here-why-delays-shipping.html
UPDATE 4 (2/5): There is a BFL update email going out now, so check your inbox. Also, Josh has been posting stuff in the last 12 hours, so I'll be sending out some quotes shortly.
BFL_Josh on order confirmation: I'd wait awhile before trying. It's not like we're going to cancle your order today. You got 10 days or so... BFL_Josh - Yeah Product server is dying.
We are doing this so that we can be sure everyone understands that the power usage is more than we planned. We don't want to get into a situation where we ship something out that someone isn't expecting.
BFL_Josh - Product server is overloaded. Wait awhile to confirm your orders. No orders are in imminent danger of being refunded without approval. Clicking accept does not change your place in the order queue.
BFL_Sabina - When the website is back up, please log in to the website and proceed with the confirmation process there. Confirmation by email is not accepted.
If you check the products page you will see the Single SC is much larger than originally intended and this confirms what I was saying earlier about the larger PCB. Will update when I hear further.. I would say they are staggering the emails as their website is overloaded and I don't have an email personally yet.. however this is all in the last 2 hours.. so we shall just have to wait and see...
Check back here for more updates. I will update as soon as it is available. Find the information helpfull? Tips are appreciated :)

BFL Jalapeno alternative?

Hey /bitcoinmining!
I recently stumbled upon some bitcoin in an old wallet, and I'm looking to re-invest my newfound wealth into BTC mining. I wouldn't be doing so looking to make a profit, it would be more of a hobby purchase. In my research, I found the BFL jalapeno, a machine that seems to fit my needs perfectly - under $500, small, and powerful. However, in looking into BFL as a company, all I can find is horror stories. Hell, the number 3 link in the sidebar is how to get a refund from BFL.
I've looked around a little bit, but all I've found (either linked from here or other places) are miners that are either inexpensive hobby miners without very much power, or monsters that cost well over $500. I just can't seem to find something small and cheapish that compares to the jalapeno.
So my question is: Is there a good alternative to the BFL jalapeno that I can purchase from a company that doesn't have a horrendous track record? I'm not looking for an ROI, but I am looking for something with a little umph under the hood: at least 5 GH/s like the jalapeno, in a box I can set on my desk and forget about, all in a package for under ~$500. Energy consumption isn't an issue.
Thanks!
TL;DR: What's an alternative to the BFL jalapeno that I can get from a non-shady company?

BFL asic update may 22nd.

https://forums.butterflylabs.com/announcements/692-bfl-asic-status-3.html
22 May 2013
Progress has not stopped here at the labs while we attended the 2013 Bitcoin Conference. We demonstrated a 5 GH/s, a 25 GH/s and a 50 GH/s miner at the conference that people could see, touch, stroke and pet, all while they were mining on an Android tablet. It was a good conference and we were glad that we could demonstrate working units and meet many of our customers and fellow bitcoiners. It was a pleasure meeting many of you.
We have resolved the issues with the long boards and are making some tweaks to the 5 GH/s boards that may reduce power consumption but will almost certainly reduce heat output. With that in mind, we should be getting about 200 5 GH/s boards on Friday, and we'll be shipping those out on Friday and Saturday.
As a term/jargon/technical note, here is the informal and/or official designations here at BFL:
Short Board = ~92mm x 92mm board that contains up to 8 chips and powers the 5 GH/s miner, typically with just 1 or 2 chips. Long Board = The board that powers the Little Single, Single and Minirig and can contain up to 16 chips in two banks of 8. Jalapeno is now called the 5 GH/s miner and is synonymous. The Minirig is now a 500 GH/s unit.
Our chips consume about 3 - 3.5w per GH/s at the chip level, so there is some room for tweaking, which we will be focusing on as soon as we get the final rev out for the Long Boards. Speaking of Long Boards, we have what we are considering the last rev for shipment coming next Monday or Tuesday the 27th or 28th of May (they may even be done with manufacturing this Saturday the 25th) and we will continue to refine the firmware for that board until the final rev arrives in KC. Assuming no problems with it, we will be being shipment shortly thereafter. The long boards will be powered by one or two PCIe style 6 pin Minifit Jr connectors. Please be aware that these connectors, while using the same form factor as PCIe connectors are not PCIe connectors, though they are electrically compatible with them (Meaning you can likely use an ATX PSU at your own discretion if you chose not to use our supplied power bricks). The Little Single and Single will have a 120mm fan at each end of the case in a push/pull configuration. Each bank of 8 chips will have a heatsink, heat baffle and 92mm fan on top of it. Cooling will not be an issue with these units and they will be fairly quiet to run if you are in a cool environment. The fan will scale up and down in speed as required due to heat. The units will be stackable and have a side to side or front to back airflow, depending on how you orient them.
We are expecting several thousand chips next week from our new packaging facility and expect to start shipping all product lines next week. Beyond that, we will be receiving thousands of chips per week at an ever increasing pace between now and until all of the remaining 68 wafers are used up. We have additional wafers on order and they should be ready about the time we've used up all 68 wafers should we need them. Soon after, we hope to have product on the shelf for immediate shipment, depending on how many orders come in between now and when we catch up the backlog.

Switch to dual-POW to give old SHA-256 miners a place to retire.

Just throwing this idea out there to see if it sticks. As bitcoin difficultly has climbed ever high older SHA-256 mining hardware has been turned off. I'm sure there are plenty of old USB block erupters and BFL Jalapenos just sitting around gathering dust. They are also pretty cheap to buy these days. How about we change dogecoin to be dual-POW coin (SHA-256 and Scrypt) and bring those old SHA miners into the doge family.

Email from BFL about rigs shipping

I just got this email:
BFL Products Shipping Now May 1, 2013
Dear earcaraxe,
Shipping of our BitForce SC ASIC miners has begun!
You may have seen news reports of our ASIC miners in the wild and some of you may have already taken delivery. It's all true. We're finally shipping. You will receive your order as we work through the shipping queue .
If you didn't know, you can check your order status on our website. Log in by clicking here. Use the same email and password you set up your account with.
If you don't have your password, use the Lost Password function to create a new one.
So what took so long?
This third generation of our SHA256 engine was a complex multi-year investment in bringing the latest semiconductor technology to bitcoin mining.
Developing a fully custom 65nm ASIC processor is not a casual undertaking. In fact, the new products have improved mining speed by a factor of 72. This much advancement doesn't come easy and it's fair to say that getting here has been eventful.
The key issue has been the engineering related to accommodating larger power draws than expected. A good example is the Jalapeno product. It was originally designed to be powered by USB but now consumes the power of a small light bulb (30w).
Consequently the power regulator, enclosure, airflow and PCB needed upgrading to suit. Although we are very aware of the undesirable dynamics of any delay, we were nonetheless obligated to make these updates in order to deliver a reliable product at the expected performance. The same adjustments have been made with all products in the lineup. You can see the adjusted product cases in our currently posted product lineup. (The Mini Rig case will be double shipped to satisfy their orders which is why we've run out Mini Rig enclosure stock).
Final confirmation is required
Please be advised that due to the adjustments described above, we need your confirmation prior to release of your order into the final build queue and on to final delivery. It may also be a good time to review your purchase altogether relative to the bitcoin market as this is the last opportunity to do so. If your order is not confirmed, it will be canceled and your money will be refunded.
Thank you for your support and we wish you great satisfaction with your product!

J'ai acheté un mineur USB en Bitcoin à Saint Lazare

Après avoir beaucoup réfléchi à investir dans le minage, fait des calculs, observé le marché, lorgné du côté des BFL Jalapeno, et vu la difficulté monter en flèche, j'ai finalement sauté le pas aujourd'hui en achetant un Block Erupter ASIC Miner usb.
Je suis convaincu que nous vivons une révolution, et j'avais envie de posséder un petit bout de cette histoire de crypto devises.
Je fais donc un tour sur le net, localise quelques vendeurs, les contacte un par un pour finalement avoir une réponse: Monsieur Spam en a plusieurs, il les écoule à 15€ pour investir dans autre chose. Rendez-vous est pris en plein centre de Paris à midi.
Je dépose quelques bitcoins dans mon wallet android, et en route pour ma première transaction crypto devise contre objet tangible.
Mon vendeur est en place, nous papotons: développeurs tous les deux, lui s'est mis à miner sur CG il y a longtemps, cette époque bénie où l'on pouvait chauffer son appart en gagnant de l'argent à coup de dissipateurs thermiques :) Les temps changent, la donne est différente; nous sommes convaincus que bitcoin est là pour durer, au moins faire bouger les lignes.
Vient le moment de payer. Je sors mon smartphone, scanne le qr code affiché sur le sien, envoie 15 euros, et "DRING" ! La transaction est effectuée quasi-instantanément, les bitcoin sont dans son wallet. Je l'invite au prochain meetup et sur reddit, on se reverra peut être, c'est une petite communauté.
Ce qui est impressionnant, c'est que lors d'une transaction de personne à personne dans le monde réel, le processus est extrêmement fluide avec les appli smartphone. 3 clics et boum c'est bon. Easy as cash !
Je pars donc avec ma minuscule machine, et me prépare à miner n'importe quoi à l'aide de CryptoSwitcher et CoinChoose... peu importe le flacon, pourvu qu'on ait l'ivresse.
TLDR: j'ai acheté un ASIC avec des bitcoin et ça s'est super bien passé.

Shipping questions and answers
Dear PimpDaddyApollojmr,
As you know, all three product lines have entered into large-scale production and many of you have received your orders. With BFL products appearing in the wild at this rate, many customers are eager to know when their particular order will arrive as well. With this in mind, we thought it might be helpful to answer some of the most common questions here in our newsletter update.
Q: When is my order going to ship? A: Orders are being shipped in the order of the date they were purchased. You can see the purchase dates being served every day on Jody's Customer Service blog.
Q: What's the status of my order? A: You can check the status of your order by logging in to your account dashboard. If your order is marked "processing", then that means your order is paid. If it's marked "production", it's on the assembly floor, and if it's marked "fulfilled", it's in a box headed your way.
Q: Has my order shipped already? A: When your order ships, you will be notified by email which will include tracking information - tracking information is included no matter which shipping option you choose.
Q: Why are the Jalapeno purchase dates moving so fast while the Single purchase dates go slower? A: We started shipping Jalapenos earlier and have already gotten through the initial large-volume order days. So even though lots of singles are going out every day, their served order date isn't moving as fast. Now that we're nearing the end of that initial surge of orders, the dates will begin to progress very quickly as we catch up to today.
Q: Can I have my Single shipped to me without a PSU included? A: Yes. Our Singles are designed with PCIe power cable inputs, like those you'd find on a modern desktop computer GPU. You can use your preferred ATX PSU, but we recommend a minimum of 300watts deliverable by the PSU for every Single connected to it. Note that many ATX PSU's won't provide power unless they detect that they're connected to a motherboard, so for those you can get a power supply tester to get the PSU to power your Single when it's connected.
Q: What about my order I just placed; how long will I have to wait? A: Daily production capacity will continue to increase until we have caught up with all back orders sometime in late September.
Q: Why does it take so long to answer all the emails I keep sending to you? A: Although we have built up a customer service staff of ten dedicated agents, our capacity is humbled every time our product cycle enters a phase of intense customer interest such as when a new product is announced or when we start shipping. This puts a lot of strain on our ability to respond. Even worse, some customers become frustrated by the delay, so they write more e-mails, but this only increases the load.
Q: But is it normal to wait more than a week to receive a response by email? Can I call you? A: Yes. While we do our best to respond to your emails quickly, it may take over a week to respond right now. We welcome phone calls, too.

[WTS] Last chance, only 19 hours left! 6.6 GH/s BFL Miner

I'm selling my BFL miner on Ebay. It sells in 19 hours, so if you bid the highest, I'll accept Bitcoins as payment (you can see in the description I say that I'd accept alt-currencies, with a wink wink nudge nudge).
If you have any questions, please ask!

Dear seppukkake,
Shipping of our BitForce SC ASIC miners has begun!
You may have seen news reports of our ASIC miners in the wild and some of you may have already taken delivery. It's all true. We're finally shipping. You will receive your order as we work through the shipping queue .
If you didn't know, you can check your order status on our website. Log in by clicking here. Use the same email and password you set up your account with.
If you don't have your password, use the Lost Password function to create a new one.
So what took so long?
This third generation of our SHA256 engine was a complex multi-year investment in bringing the latest semiconductor technology to bitcoin mining.
Developing a fully custom 65nm ASIC processor is not a casual undertaking. In fact, the new products have improved mining speed by a factor of 72. This much advancement doesn't come easy and it's fair to say that getting here has been eventful.
The key issue has been the engineering related to accommodating larger power draws than expected. A good example is the Jalapeno product. It was originally designed to be powered by USB but now consumes the power of a small light bulb (30w).
Consequently the power regulator, enclosure, airflow and PCB needed upgrading to suit. Although we are very aware of the undesirable dynamics of any delay, we were nonetheless obligated to make these updates in order to deliver a reliable product at the expected performance. The same adjustments have been made with all products in the lineup. You can see the adjusted product cases in our currently posted product lineup. (The Mini Rig case will be double shipped to satisfy their orders which is why we've run out Mini Rig enclosure stock).
Final confirmation is required
Please be advised that due to the adjustments described above, we need your confirmation prior to release of your order into the final build queue and on to final delivery. It may also be a good time to review your purchase altogether relative to the bitcoin market as this is the last opportunity to do so. If your order is not confirmed, it will be canceled and your money will be refunded.
Thank you for your support and we wish you great satisfaction with your product!
Jalapenos Out the Door Packaged for its adventure to a new home. Bye Jalapeno! Your owner eagerly awaits your arrival.

[WTS] 23.5 GH Mining Rig

At the moment I'm fielding offers for the entire mining rig.
I will not be parting this out and will be selling at as one entire unit. I will pay for shipping. US only.
Miners
Equipment
Current setup allows for 12 in each internal USB hub, 5 in each 7 port hub a max recommended of 9 for the two 10 port hubs. You can try pushing it with 1 more in each of the 13 porters and 1 more in each of the 7 port hubs but it isn't recommended. Based on that, there is room for 4 more usb miners recommended setup, and 8 if you want to push it.
http://imgur.com/a/Rm5pf
Please post an offer below. Going by current prices I'm looking for 8+ BTC. (Miners and Jalapeno alone at current prices around 7.8 BTC, .1 BTC per USB Miner and about 3 BTC (per ebay) for the Jalapeno) I know I won't be getting back what I paid for, but these are quality hubs and power supplies.
I've also put this on Ebay http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=281182502521, but I would prefer to sell it for Bitcoin.
