Not sure why it would matter, as long as they got their box back.
Not sure either, I'm just going off this quote from BFL, which makes it sound like only singles purchased from BFL would be covered. The trade-in program involves return of a single, a mini-rig or mini-rig cards purchased from Butterfly Labs.
The date of purchase does not really matter, the credit is given to the customer as soon as the unit
reachs our office.
Straight off the BFL SC FAQ on the website: "Upon release of BitForce SC based Singles & Mini Rigs, all previous generation BitForce products will enjoy a full 100% trade in value when used towards the purchase of the newer generation replacements. This means your current device is protected from depreciation through this evolution in technology. This buy back offer is good for all previous generation BitForce units whether purchased directly from us or from a third party."So to answer your question, yes, they will accept anything whether purchased from BFL directly or not. Didn't someone send a broken BFL Single to the maker of Lancelot to hack? ....  ooops |

we can add as many decimal places as we want..... 16 would be easy
Yep, when Bitcoins were at $20 in July, there were plans to add another decimal place in case the value increased any further. It's literally a line of code change and shouldn't have that much of an impact. Code in the client software? |

Sorry, I was always under the impression that it was more fixed. That seems like a viable fix or workaround. Perhaps, the best thing to do for now is to store them to reduce risk of loss. For example, If you used a flashdrive for storage, I would personally not do that. They seem to go bad easier than I'd want to risk with any significant amount of BTC. |

This thread is like menstruation. Usually comes every month lol
Why don't people learn to how use the search?
I know how to search, but chose not to. Thanks anyway. BTW: How many times would the topic of menstruation appear if I did a search?  |

But assume the decaying number of bitcoins is real problem. Then your bitcoins may be so rare as to be useless as a currency. Granted, that may not happen in our lifetimes.
Lets say we loose so many Bitcoins that now 0.00000001BTC (1 satoshi) is worth $1. No problem, all we have to do is add a couple of extra 0's (small change in client software) and were sorted, we'll just price everything in Satoshi's. I don't see how this could make it useless as a currency. How many Satoshi's are there? 21*10^14 ... 2,100,000,000,000,000  ... Something like that. A lot I know. With the current world population at about 7,000,000,000. So, maybe 300,000 Satoshi's per person? Care to verify for me? In that case  It shouldn't be a problem anytime soon like I said before. But a hundred years down the road, how many BTC will be lost? Flash drives die very easily. And in these days, if they die, they take out several BTC's, not the very tiny Satoshi's. |

When Bitcoins get lost it increases the value of every other Bitcoin as the supply has decreased.
There is no real reason to bring back lost coins. What if I want to leave an inheritance in BTC for my family? I'd have to keep moving it around every 10 years otherwise I'd lose it with your proposal.
The reason to bring them back would be to keep the money supply viable. I'd rather do that than to take benefit of increasing my BTC value b/c others lost a bad flash drive or something silly like that to which we are all subceptible. It's not a proposed solution I'm stuck on. Just hashing the idea out to look ahead and solve it. Anyway, make it twenty years if ten years is too soon. Takes just a few clicks per twenty years. If you forget to do it in that period of time, maybe you already effectively lost them. Another thought might be to peg BTC to gold, and then increase the money supply after the last bitcoin is mined. Just brain storming. |

And what of the bitcoins i put on a flashdriver/paper wallet and put into a time capsule?
whats the point of having a store of value without being able to store value?
Minor inconvenience. The value is still there, you'd just have to log onto your flash drive once every ten years (maybe twenty) and just shift the bitcoins to another account in the same wallet on the same flash drive. But assume the decaying number of bitcoins is real problem. Then your bitcoins may be so rare as to be useless as a currency. Granted, that may not happen in our lifetimes. |

There will be a maximum number of bitcoins discovered. Bitcoins can be lost. I realize they can be divided to so many decimal places, but disregarding how long this would take to become a problem. Assume it is. What of the idea to "re-encrypt" (for lack of better term) any bitcoins that have shown to be inactive in all ways for something like ten years. In other words, people would have to at least relocate their bitcoins to another of their wallets accounts or spend them within ten years for them to remain in the economy. Otherwise, they could be assumed lost coins, and buried again to be re-mined (like finding some lost gold on the beach). Or re-distributed to all active wallets Late entry: This solution could possibly be implemented when/if it does become a problem, I'd guess. But should the community have to wait to see when this happens? |

I just ordered one today, and while customer service is extremely fast, they said that lead time was 9 weeks. That's as of today May 24th
I ask about 'lead time' for Singles a week and half or two ago. BFL responded: "Turn around is supposed to be 4-6 weeks, but we have been exceeding that." |

Hey,
That would be fine for me if the FPGA chip was not included. I would just really like the kit to include the daughter boards and back-plane and parts needed to construct the miner. What would be the cost of the kit without the FPGA chip? I would be interested in something like that for sure if it was cheap enough.
Same here. I'd buy a kit without an FPGA. But would hope the design is proven not buggy. Also, would need direction on how to proceed with loading FPGA. |

I may be able to make a kit or something..... actually the original plan was to just sell kits but I figured most people wouldn't be able to or wouldn't want to solder the 484 ball BGA and all the tiny 0402 capacitors and resistors + the ARM chip that only has 0.008 in. between pins..... I would be happy to make a kit though as long as there is enough interest.
I think there is interest. It's scattered, but they will come. You could even initially create a thread to sell the full blown, non-buggy(!) design and initially sell the design plans. And thereafter, if you wanted to compile and sell a kits, you could probably do that too. See my thread linked below, and you can see that it started to generate interest from the start. But it fizzled soon after, maybe because people realized it was best if was backed by someone with FPGA circuitry know-how. https://bitcointalk.org/index.php?topic=78935.0On top of all that, you can get feedback from us and we can together streamline the process to reduce costs even more. Six sigma!  One example I can think of, but admittedly just speculating on, would be to consider if the traces on the PCB could be made to act as caps near the FPGA (cost savings built into the design). I'm not sure if it would work, since the capacitance value might be greater than a thick PCB dialectric would allow practically. A capacitance measurement on parallel traces could test this idea. [late entry: I just saw that the capacitors are super cheap, so this would not be a significant cost savings at all, but if it was easy enough to design into the PCB, it could at least save the time to solder them into the circuit] I have 10 BTC waiting to barter for a complete non-buggy DIY design. |

Well I see this project is the design used by btcfpga.com. What am I wondering if the complete plans for this have ever been released. I mean I see so CAD designs of the PCB boards but I cannot submit those to a company to produce them.
What I am trying to do is basically build my own FPGA boards with this design because I really like this style of miner. I am really hoping that the original poster will release the designs for his PCB boards so I can get some made. I would really love to try and build my own FPGA miner. I am willing to risk screwing up a little bit as well to learn how to build these efficiently. I know that I am asking a lot but would it be possible to get a complete parts list and the PCB board designs so I can submit them for manufacturing. I really t
I'd also like to make my own. But seems these DIY threads tend to dry up as quickly as they start. |

The whole point of it denying you entry (with an increasing timer) is to prevent somebody guessing common passwords and eventually finding the right one for your account. Allowing someone to bypass the lockout once they enter the correct password would completely defeat the point of the lockout.
If you've tried to send me an email, I have not received one describing anything remotely related to what you've stated in this thread.
EDIT: If you're trying to login via TOR, it is entirely possible that somebody else using the same exit node was trying to get into someone's account. The lockout is IP based. You're allowed one failure in 24 hours with no penalty. Then the penalty is 1 second. Then 2, 4, 8, etc. The lockout is exponential based on failed attempts from your IP in the past 6 hours. The maximum lockout being 1 hour between attempts (3600 seconds).
The email I sent went to " webmaster@btcguild.com". And I did get a response, just checked. My account apparently got "pruned" or deactivated due to my inactivity (I was out of the country for 9 months). I understood the point of it increasing the timeouts. It makes sense from a security standpoint. But after I saw that the time keep going up, I waited more than an hour and it still didn't work. But it was made clear to me that the problem was my inactivity... and trying again (just now) a new message appears. I did not see this one erlier today. The message reads: "Your account was pruned from the active users database due to inactivity. An automated restoration of your account is being run, please try logging in again in a few seconds." Which concurred with the email from the webmaster. I tried again...and it let me log in. So, my problem was resolved. However, I do recommend the website be reprogrammed to warn people that login is failing due to a pruned inactive accounts. Seeing what happened, I will not use this as an excuse to move to another pool. I'll stick with it for now.  Thanks for your thoughts and help. |

It has been a long while since I logged into my mining account on BTC Guild ( www.btcguild.com). I tried and appraently used the wrong password. Ooops, no problem right? Wrong. The site says the IP adderss I was at is restricted for x number of seconds. Well, despit enow using the correct password, x keeps increasing each time I try to log in. Despite even giving it a rest for hours. It's a bit insane. As long as this website has been around, you'd think they would have a streamlined login and password reset feature. It's time to find another pool. Any suggestions on pools that are well designed for the user? Hmm, I think I would email the pool op or post a message the pools thread to find out what exactly the problem was? But that's just me I guess. If you change pools every time you have a problem with one you should be solo mining by now. Sam I did email him/her already. But in the meantime, I think that to have this kind of issue after the pool has been online for so long makes no sense. I can't see anything as a user that I can do differently. I'm probably not the only person to forget a password there. Anyway, it was the only pool I was in to date, and I was thinking that if it is that easy to get perpetually locked out of an account, then taking a low risk move to a new pool might not be a bad idea. Thank you for your thoughts on it. ||bit.out |

It doesn't appear to be a reason to move from BTC Guild. However, I will recommend that the webmaster change it to indicate an inactive account instead of an endless faulty password message. |

There aren't many pins used for communication. Usually 2 for actual job/share transfer and 4 for JTAG or some other means of bitstream upload.
The vast majority of pins is for the three required power supply rails, one of which is carrying like 10 amps of current any may not have more than very few milliohms of series resistance. I'd think there are like 100 power supply balls total on that package.
From that, I would think there is no need for a multi-layer PCB to support a FPGA chip like the Spartan 6x150. Is that an accurate notion? |

rph's boards are all custom and professionally produced. In fact, I'm pretty sure he ended up having the FPGAs soldered by a shop as well, but did the first ones himself by hand for prototyping (although I could be wrong about that). There is definitely an advantage to having them done by someone with the right tools. It costs money, but how much does your time cost? Not to mention the FPGAs that don't survive. In my experience, DIY is not about saving money. In fact, most of my weekend projects have been a huge money sink. That's not to say it isn't fun and educational, though! Admittedly, there is an element of fun involved, even in the prospect of considering DIY...and a dash of frustration...or maybe better stated, a cup of frustration.  I was looking at the images of the X6500 board here: http://fpgamining.com/products/x6500-rev3How many pins or balls or whatever are actually connected & used outside of the FPGA chip? It looks like only a few capacitors on the underside are used to connect some balls or pins, and a few traces on the top surface are used. Am I missing a lot of connectivity that is happening in middle layers? I am curious about how many pins are utilized for the input and output to the chip in normal operation. I don't see why all the dozens of pins or balls need to used on the chip during mining. Seems just a single data input, a clock, VCC, common and a single output are enough. Unless of course you have many inputs/outputs that go to or come from different/parallel 'threads' for lack of a better term. ||bit.out |

Did you try adjusting the rheostat from the 'darker' to a 'lighter' toast setting on a subsequent attempt? |
|
|

Interested.
How about we create a fund to pay for research or pledge to a developer?
I'm in 10BTC for the start.
Sounds good in concept if we were to set a ~1MH/$ goal, and require proof that it would work. |
