1  Economy / Computer hardware / [WTS] 24x BFL Single SC 60GH/s - February 2013 MiniRig order‏ on: September 26, 2013, 03:45:19 PM
I'm looking to sell and transfer my order from BFL which I opted to convert to 24x 60GH Singles from the original 1500 GH Minirig. Just want to see if I can sell the lot in one go.

Will escrow for the transfer of the order.


Please PM me if interested  Smiley
2  Economy / Computer hardware / [WTS] (3x) 500 GH MiniRigs or (24x) 60GH Singles - Feb 22 2013 -155 BTC (0.1/GH) on: September 12, 2013, 02:57:50 AM
I'm looking to sell my 1500 Gh/s (1.5 TH/s) BFL order. Even though they are shipping, I can't host all of them.

Order #171XX, placed and paid for on Feb 22 2013.

You can have it shipped as 3x 500 Gh Rigs, or 24x 60Gh Singles if preferred. Note that their Singles are shipping a lot faster than the Rigs right now.


Asking BTC 155 but open to offers. Will escrow through John K with release once the order has been officially transferred.

Feel free to PM me  Smiley


3  Bitcoin / Hardware / Anyone demonstrated a 28nm ASIC mining bitcoin yet? on: August 22, 2013, 04:36:40 PM
There's a lot of discussion about 28nm ASICs out there, but I can't find any proof that shows one actually running, with a hashing output and a watt meter.

I know "proof" is subjective, but besides receiving a unit and testing it myself, a video or review by a trusted 3rd party would suffice for me.
4  Bitcoin / Hardware / Redundant backup host machines for custom USB mining hardware? on: May 27, 2013, 09:11:41 PM
When the host machine providing work to your miners stops working for whatever reason, the miners stop mining, obviously.

Is there a way to connect your USB hardware to multiple hosts, so the backup machine(s) takes over, thus reducing your downtime?
5  Bitcoin / Mining / ASICMINER: 200 TH/s has been ordered for 2-3mo deployment timeframe. on: May 08, 2013, 07:56:41 PM
Quote from: furuknap
I would love to know

1. What are the two-three month perspective on hashrate, earnings, and profitability
[...]
1. 62+200=262TH/s. Earnings and profitability highly depends on the competitors and how the price range the purchasers will accept after two to three months. And please bear in mind that they are perspectives, only bonds could usually give a fixed range of profit predictions.

https://bitcointalk.org/index.php?topic=99497.4640


The current TOTAL NETWORK hash rate is only ~77 TH.

Is this not a huge 51% threat, or am I missing something? (besides BFL)
6  Economy / Computer hardware / [WTB] [LOOKING FOR] LGA775 Quad core CPU(s) - Shipped to Canada on: March 24, 2013, 07:35:24 PM
I'm looking to buy 1 or 2 QUAD core LGA775 CPUs to upgrade my Dual Core machines, shipped to Canada.

Don't mind using escrow if you can set it up with someone trusted and with escrow history on this forum.


PM me with what you have  Smiley

7  Other / Off-topic / BFL is keeping a portion of first batch chips for their own mining farm on: March 24, 2013, 05:11:27 AM
Quote
3c. are any of these orders likely to be part of the 'first batch' shipment from BFL?

Some of them are, not all of them.  The number that will be in the "first batch" is kind of up in the air at the moment, given the current disposition of our first batch. Since we have a limited number of available chips for the first batch, I will not, in good conscience, be taking a large swath of them.

Quote
3d. what is the (best guess) expected rollout schedule once ASIC shipments start and conversion begins?

I don't currently have one, and will be doing this based on what's available and trying to serve the customers of BFL fairly.


Is it just me, or is it scammy as hell to keep orders that would've otherwise gone to first batch customers, who pre-paid over 8 months ago, and who have already been waiting 4 months past the original delivery date, just so you can upgrade your own operation's hardware?

I hope it's just me over reacting  Huh


EDIT: This is from June 2012


I am opening a new offering, basically mirroring the BFLS product.  It is for the MiniRigs & SC ASIC offering.

IPO will begin tomorrow:

6058 shares will be allocated and sold per Minirig, initially 2 rigs worth of shares will be allocated, and 6058 shares can be traded in for the physical Minirig hardware. 15% of the shares will be kept for maintenance and operation costs.

Once the details of the ASIC unit orders are publicly available, available shares will double and be put up for sale. At that point, it will require 6058 x 2 = 12116 shares to convert your BFLS.RIG shares into the physical hardware (Mini-Rig or SC).

Dividends on RIG will be paid out the same way BFLS is currently paid, on a weekly basis and the amount will be what the unit(s) generate that week. Obviously, no dividends on RIG will be paid until the hardware is in actual operation.

RIG shares purchased are for a share of the unit, not to help fund the purchase of a unit, since the units have already been paid for. Funds will be reinvested into further ASIC orders, which means the ASIC units will be "pre-purchased" already, and you will be buying into already purchased ASIC units with your BFLS.RIG shares, not funding the purchase of ASIC units. This is an important distinction, since it means you'll start generating revenue much faster than a unit you would be "funding" the purchase of.

Ticker symbol is BFLS.RIG


The silver lining is that Josh believes in the ASICs enough to pay for some himself.

That begin said, should BFL fold, he'll be the first and possibly only one to get his money back  Tongue
8  Bitcoin / Mining / Harnessing wasted heat? Post your pics and ideas! on: March 21, 2013, 04:45:01 AM
Following a recent discussion, I thought it would be cool to start a thread so people can bounce ideas off of each other on all the possible ways of capturing the heat that mining rigs give off.

Since ~99% of the power consumed is converted to heat, there's a lot of potential for recouping or re-purposing that energy.

Obviously if you ever turn the heaters on in your house, a mining rig can offset some of the heating required, but I'd like to see what other creative ideas people might have.


Here are a few suggestions I've seen on this forum:


If I was generating that much heat, I'd probably figure out a way to heat my hot water with it too...lol.



I have a liquid cooled miner.  It is dead silent,  but the main point is that it heats our bathroom floor.  Pictures says more than words, so I attached a few.

Tubes under my bathroom floor and one of the temperature sensors (inside a blue shrink hose).  This is now buried in cement and covered with nice tiles.

The best thing about my water cooling and floor heating is that my wife keeps nagging me to buy a second 5970 to make the floor warmer.  Beat this with a air cooled system. :-)

9  Bitcoin / Development & Technical Discussion / Are 6 confirmations really that necessary on: March 10, 2013, 11:28:34 PM
We've all read about the 0 confirmation double spend, but I have yet to see ANYONE cheat a transaction with so much as 1 confirmation, let alone 2, 3, 4, 5, or 6.

So why are 6 confirmations touted as full proof? It sounds like someone arbitrarily picked 1 hr as the magic number. If you had the power to manipulate a transaction with even 2 confirmations, wouldn't the bitcoin network have far bigger problems than even 6 confirmations could solve?

DailyTech - Bitcoin Rollercoaster Ride Sees Currency Soaring to New High of $32/Coin

Some of these comments are so misguided (and some have very valid points):

Quote
By p05esto - I can't help but feel that at any point Bitcoins could instantly go to $0 in value. They seem really sketchy and mostly used by people doing illegal things. Could just be me, but this is how I feel and why I keep away with a 10' pole.

Quote
By kleinma - [...] Bitcoins if I understand it correctly are just hashes of data generated from video card GPUs. Meaning that as the GPU gets better, more coins can be produced, and eventually people will be able to make how ever many they want, causing the whole system to fail, or just inflation to cause one US dollar to equal 50 billion bitcoins where it is not worth it to have them.

Quote
By Solandri - A currency needs to grow slightly faster than the economy. If it doesn't, it becomes more cost-effective for currency holders to stuff it under a mattress and wait for its value to go up, instead of using that currency to increase their productivity through economic activity.

Quote
By Gondor - It is amazing that there are gullible idjits out there who would put a value on something as imaginary (and backed up by noone) as "bitcoins".

The thing with "bridge for sale" springs to my mind whenever somebody mentions this crap. The funny part about this particular bridge is that it is free (as in: everybody can create one at no cost). How daft must one be to invest real money in something like that ?

Quote
By TSS - I hate Bitcoins. There i said it. I have and always hate them and their concept. For a very simple reason.

Right now, we're paying with money that's made up out of thin air. The vast majority of money is virtual, made up by typing numbers into a screen. Now there are some problems with that.

But bitcoins are virtual money, paying with thin air, that you first have to burn a real world lump of coal for, before the numbers are typed into the computer. How else is that GPU getting the power in order to mine bitcoins? the biggest source of power in the world is coal. Wether we have a script add the numbers or a human doesn't matter, they are still digital bits floating around in cyberspace.

This is the madness that i hate. Rather then saying "right we just won't print any more money", we have to burn real world resources to limit the creation of virtual money. It's the ultimate form of decadence. Instead of paying for something with nothing, you pay for something by destroying another thing.

i HATE em. I'd rather return to gold, and i really dislike the gold standard for the same reason, turning a society that has learned to pay for something with nothing back into a medieval society which *has* to pay for something with something else or nothing gets done.

We could just, get this, put it in the constitution that the government is the only entity allowed to print money, and then, in that same constitution, tie the rate of inflation to the rate of growth of last year. 2% growth last year? 2% inflation this year. And then NOBODY gets to change that anymore. It can only possibly be changed by a 2/3rds majority in house, senate, president has to agree AND a referendum has to be held in which >60% of the population votes yes. It'll be a cold day in hell before all of that happens. And when the economy shrinks more or grows less then the numbers allow? TOUGH.

No need for bitcoins or massive lawbooks. The only problem that needs solving is people printing *more* money. Not people printing money.

Quote
By Shadowmaster625 - Only a fool would use as a store of value a currency that went from being worth $2 to $32 in a year. Imagine if the dollar went from being worth 2 to 32 euros in a frickin year. It would kiss its reserve currency status goodbye. (Assuming it was the dollar and not the euro that was so volatile!)

^Now that's a fair point, but this "fool" would be 16 times richer if that were the case.

By schmandel - It's safe to say that Bitcoin would not be around were it not for its use for black market transactions, primarily the Silk Road web site on Tor. There was some early interest in money laundering, but it's just another tool with limitations in this regard and really too small to handle laundering placement volumes for work of consequence. Bitcoin is way too much of a PITA for any legitimate payment system use unless you are some sort of True Believer ;-)

The limited number of Bitcoins is a feature that is a tribute to the idea of money that doesn't inflate due to fixed supply ( e.g. gold ) and all the magical ideological thinking that comes with it.

It is all working out as the creators mush have intended, the coins they mined two years ago for pennies are now worth dollars, a few parties hold nearly all the bitcoins in existence and are the central bankers of this not-so-decentralized currency.

Outside of the transaction engine itself, the Bitcoin infrastructure is remarkably amateurish and crappy, leaving it rife with hacking issues and fraud.

If small time black marketing and wing nut economic theories turn you on, Bitcoin just may be the place for you. However, if Silk Road is broken by law enforcement, I would expect Bitcoin to be gone, gone, gone.
11  Bitcoin / Bitcoin Technical Support / Any good method of reducing the size (dust) of your transactions? on: February 26, 2013, 07:56:47 PM
I recently made a large bitcoin purchase and was hit with a 1.0 BTC transaction fee.

I've read all the posts about "dust inputs" and "coin age" etc etc, but it all seems like so much technical jargon when all you want to do is make a transaction.

Is there any good practice for consolidating your coin in/outputs?

Lets say you have a wallet with 100 btc. At least with the standard client, you have no idea what that's really comprised of, or how many of those are old enough to be sent without a fee.

Is there a way to mop up the dust beforehand? Instead of having to find out they're too scattered at the time you need to send a payment.
12  Economy / Speculation / Is someone TRYING to crash the bitcoin exchange, or just old miners cashing out? on: February 14, 2013, 04:42:05 AM
The last dip to ~$21.7 looked like a party crasher was trying to dive bomb the exchange, rather than cash out slow and steady.

Just curious if anyone here has any economic experience in this sort of thing, is this attempted sabotage to shake investor confidence?
13  Bitcoin / Hardware / Are ASICs the last major evolution in mining hardware? on: February 01, 2013, 09:04:59 PM
Bitcoin was released into the wild in Jan 2009 and was first mined on CPUs, which everyone who learned about Bitcoin already had access to.

Then around Sep 2010 the first GPU miner was released. It picked up fast because GPU's were available off of any computer store shelf, and most PC enthusiasts already had one in their machine.

Sometime around May 2011 the first FPGA was demonstrated. FPGA chips were already available, but required assembly to work as Bitcoin miners.

Now we have ASICs coming onto the market, which are purpose built chips, designed for the sole purpose of mining Bitcoins.

The big question is, where do you go from here? Or is this the last major leap for Bitcoin hardware?
14  Bitcoin / Hardware / Is an 80% decrease in power consumption possibe when going from 110nm to 65nm? on: January 31, 2013, 04:55:09 AM
Crunching some power consumption numbers here and a little skeptical at BFL's specs showing 1W/Gh, considering Avalon gets about 6W/Gh 9.4 W/Gh.

Anyone here familiar enough with chip design to weight in on this?

EDIT: Looks like Avalon falsified their real world numbers on their site, even after the fist machine was already in customers' hands. They updated them to "reflect customers' experience" to 620w for a 66Gh/s rig.
15  Economy / Currency exchange / [WTB] BTC in Vancouver, Canada (or Langley, Abbotsford, Chilliwack) on: January 18, 2013, 04:34:42 PM
I'm looking for a steady supplier of bitcoins between Vancouver and Chilliwack.

I'd like to buy them face to face every few weeks at first, and eventually move to buying a steady CAD amount every week or so using an online payment option (whatever the seller would prefer).

PM me if you're interested in selling and are in the area  Smiley
16  Other / Off-topic / What's going to happen to the old returned BFL Singles and Mini-Rigs? on: October 05, 2012, 05:32:21 AM
Does anyone know what BFL is going to do with all of the old/returned Singles and Mini-Rigs after the trade-in period has ended and they effectively become outdated? Will they be re-purposed or recycled in some way?

I ask b/c I'd like to pick up a Mini-Rig for old times sake, especially if I can get it for the same $22/Gh ratio as the CS single, which comes to ~$540 (compared to the current going price of $15,000).

Anyone have any information?
17  Other / CPU/GPU Bitcoin mining hardware / Boot display signal sent to card without a monitor on: August 29, 2012, 08:11:25 AM
I've had this problem since last year, and I'm wondering if there's an easy fix I'm missing.

When I boot my PC with 4 cards, the boot display signal is always sent to the card in the lowest PCIe slot (furthest from the CPU), whether it has a monitor plugged in or not, which doesn't make any sense.

Any easy fix for this?
18  Other / CPU/GPU Bitcoin mining hardware / So THIS happened (burnt mobo pins), what should I do? on: August 24, 2012, 02:58:33 AM
After a year of running 5x 6950s, with the cards powered off of an OCZ 1250w and the mobo/cpu off a CM 500w, the ASUS P5N-T Deluxe refused to boot. Then I found this:



Obviously 5 cards was too much power draw from the 5 un-powered PCIe x1 ribbon cables.

I have some spare 4-pin molex connectors, is there a mod that'll let me connect power to the PCIe x1 riser cables?

I also have an identical board that was DOA, so I'll be re-sodering the 24pin ATX socket this weekend, but I'd like to make sure it doesn't happen again too.
19  Other / CPU/GPU Bitcoin mining hardware / 4 dead PSUs, there HAS to be a commonly failing component on: July 31, 2012, 01:49:30 AM
In the past year I've had over 4 "out of warranty" PSUs die on me. A 750w Silverstone, 450w and 480w Antecs, a 400w Enermax and a few no name ones.

So now I've got a box of dead PSUs and I'm thinking, there's got to be a particular component that's responsible for a large portion of the failures.

And yeah, I've heard all the "Deadly Internal voltage" warnings etc. I always wait a day before opening one up, but I've pulled apart quite a few to recover the fans, so now I'm looking to actually repair them.
20  Bitcoin / Bitcoin Discussion / Comparable Bitcoinwatch.com sites? on: July 12, 2012, 03:43:27 AM
