Buffer, 5:11 PM
Hello, i do, price is 15$ per key, payment is in bitcoin
Let me know if you need a download link
5:12 PM
Sounds good. I will need a download link. Bitcoin address?
Buffer, 5:13 PM
Ok
How many do you need?

Just one
What exchange rate shall I use? You don't accept any other crypto with lower fees, do you?
Buffer, 5:16 PM
No, sorry, only bitcoin
You can use preev.com rate
Just make sure to pay enough for fees
5:24 PM
Ok, funds sent through an exchanger - you should have them in about 10 minutes. 0.000323BTC sent (per preev.com)
Thanks very much!

Complete Scam. Comes across as responsive and helpful, and the MOMENT coins are sent, he's gone, never to be heard from again.
How is this guy still allowed on here?

current buys on bitstamp:

550 1239
545 1801
540 2611

510 4334
505 4557
500 4970
495 5265
490 5418
and there you come with your 30000.
It will cause a drop from 560 to about 500 if they would be sold in one time. Ridiculous.
2 Minutes later, the price would be at least at 540 again.
Invalid logic. Those numbers are cumulative. (At that time) a (market) sell of 4970 BTC would have driven the market to 500USD. You don't add all of those numbers up, that's why the bid wall is ALWAYS higher at each lower value. Notice that if you look down the list, the USD goes down and the wall goes up - without fail.

nah, merely technical reasons.
The field size to store in a computer's memory an amount of Bitcoin is 16 decimal places. Typical variable size. 8 places before the decimal point (as the maximum amount a transaction can be is 21 million), and 8 places after.
Satoshi merely and probably pretty arbitrarily placed a decimal point in the middle, for convenience, thinking that this will roughly do in the foreseeable time.
Although I agree there was probably a technical reason for the 8 figures of precision, it had nothing to do with "8 places before and 8 places after". Even if we were talking about typical variables, you're probably thinking of, for instance, 8 BITS before and 8 BITS after, not 8 figures in base 10. The output variable in bitcoin transactions is an 8 Byte variable where each unit represents 1/100,000,000 of a bitcoin. Thus, the minimum transaction is (0x0000000000000001 / 100000000) = 0.00000001 BTC (Aka 1 Satoshi) and the maximum transaction is (0xFFFFFFFFFFFFFFFF / 100000000) = 184,467,440,737 BTC Why exactly 8 bytes were used when 7 would have been able to create a transaction that still contains more BTC than will ever exist (720,575,940.379 to be exact), I can't be sure. It seems to me like a gigantic waste of a byte in the blockchain for every transaction. Enigma |

Bitcoin might not be dead, but until they figure out a permanent solution to prevent exchanges from dropping like flies needing centralized exchanges, I'd say Bitcoin is in a deep coma.

Any competent electronic shop can repair that in less than 10 minutes. Check your area for "Electronic Contract Manufacturer". They'll probably charge you tech time at 40-100 bucks per hour (depending on area of the country), but it's a piece of cake repair. Yeah, the pads and some of the traces have been ripped off, but that's no big deal for anyone who is a real technician.
If there are no Electronic CM's in your area, try a HAM Radio repair shop - some of those guys are pretty darn good.
I can't even tell you how many USB/HDMI/etc connectors I've fixed for people who did the exact same thing. Solder connector in place, solder pins to any remaining pads/traces, use wire-wrap wire to extend pins to missing pads/traces. Easy as pie. Add a few dabs of scotchcast for good measure so that the connector can NEVER again be ripped off.
Best of luck,
Enigma

That would explain the (pretty significant) volume drop on Huobi, but why BTCe, Bitstamp, and Gox?
Because those are Chinese traders too. and Gox is based in the United States Um. No. Thanks for playing, try again. |

That was a very, very interesting documentary. Thank you for sharing! |

Just a thought: can`t we just hard fork bitcoin to invalidate the coins in posession of the FBI?  It goes against just about everything I believe in, and yet I can't help but love that idea  |

There is nothing magical about today's price or $1000.
They are your coins, do with them as you please, but if you want to lock in some profits, my advice would be to sell proportionally to the price.
Lets say you have 100 coins, currently worth ~$350K. Pick some number you are comfortable risking. Lets say $200K. So you sell the difference, $150K worth of bitcoins now. If/when bitcoin continues to rise in price, keep selling so that your remaining coins are still worth $200K. That way, not matter how high bitcoin goes, you will never completely miss the boat, perhaps one day you will only have 1BTC left, but it would still be worth $200K. At the same time, no matter how low it drops, you would have locked in a decent chunk of profit.
ANyway, thats roughly how I do it, and have been doing since $100/BTC.
And sure, "had I known", it would have been better to keep those coins, but I dont regret my strategy one bit.
Absolutely. Please take the advice of someone who believes 350 * 100 = 350,000. Excellent Plan. |

Hello everyone,
I have been tremendously busy the past few weeks, and I've realized that when these chips ship, I'm not going to have time to do anything with them. I've got 40 chips from this batch (3.233 BTC Cost). If anyone would like to add to their own order, I'm willing to sell these 40 that I've got coming.
PM me an offer if interested. We can do the full transaction very publically here.

German customs seem to love refusing ASIC's..... some BFL's were also refused
Corrected: German customs seems to love refusing electronics that don't have the proper certifications and are therefore illegal to import.... Some unmarked BFL's were also refused. Enigma |

Um.. What? Given a 2 layers board and a 32Mhz oscillator that is routed all over the place, I think the FCC would not be so sure..
Enigma
2 layer board? The clock is routed in the middle of a GND plane and has one below and a power plane above. And there is GND stitching around the edges. While I don't have access to FCC testing facilities here I'm reasonably sure that a 32 MHz clock won't cause any grief. It could be different if the 300 MHz hash clock was route all over the place. Was the comment about "insane power supply" in that other thread aimed at mine? I'd like to know if someone else said that. I thought you were doing this in 2 layers.. I suppose I haven't paid that much attention though.. Agreed, should be fine then. Maybe I'm remembering something from the very early days of your development. Not sure what you mean about the insane power supply - I don't even recall talking about such thing, so it obviously wasn't aimed at you.. Enigma |

Enigma
For example take a ATX or mATX mainboard. It has multilayer circuit (not 2 layers), the oscilator is greater and there are more circuits than on the K16. The power feeded into the board is huge compared to K16. Not to mention the power filters and transformers. So I assume that the circuit traces of the K16 are not enough to emit EM interference so that the values are greater than FCC aproves. And let's keep in mind that those values are given at 1 meter from the device You will not sleep with the k16 boards. In my opinion this is somewhat not important to discuss since there is more EMI using a cell phone. And if you decide to have a "farm" of k16 they will probably be placed in a location far or away from people (due tot the heat and also to prevent accidental intervention). And anyway we are discussing about an experimental device. There are lots of things to improve and this is only one thing of them I love self proclaimed EE's. Where's my facepalm picture... |

Comments? Quote from: JHenderson on Today at 08:40:04 Thought FCC guidelines were to resolve interference issue with other electronic components not mitigate against potential heath risks. FCC and FDA are different Contrary to all my competitors I do take EMC seriously and designed these boards to be compliant. (which did increase price) Emission testing is scheduled for next week, but the Lab hasn't yet confirmed my appointment. The boards will be tested against EN55022. https://bitcointalk.org/index.php?topic=179769.msg2678377#msg2678377There are no components on the board that their function will generate interference greater then the maximum admissible value of FCC. This is just marketing IMHO. Um.. What? Given a 2 layers board and a 32Mhz oscillator that is routed all over the place, I think the FCC would not be so sure.. Enigma |

GREAT NEWS!
I've got it running at 300MHz and it's much more reliable than at lower speeds. I now have 2 chips doing 600 MH/s total with fairly long periods with zero HW errors.
I tried several capacitor values for result capture and the 30pF works well up to about 360MHz. At 380MHz it's lost sync. I tried a brief run at 360 MHz and it worked ok. I need to get a fan working before I run extended tests at higher clocks.
I'm following, but not super closely.. Doing Result capture like this, are you using good capacitors (2, 5, at most 10%) or are you using standard +80%/-20% caps? If you're having to tinker with values that much, then variance between the parts that people buy is going to be a real issue.. Add-On: I just looked.. the 30pF is a 5% part, so that's a plus.. I would still suggest buying a few of the same part number from different vendors (to guarantee you get samples from different manufacturing lots) and make sure the variance doesn't cause issues..

... If I added a 1of4 analog switch and used the 2 available lines then I could sequentially sense each of the 4 thermistors, allowing separate readings for each quad. I could then relay them as status values for the driver to decide what to do. IS this something that is worth added cost of a switch chip?
I would say 1 sensor for 16 chips in the center on the heatsink. The heatsink will spread the warmth more or less and a sensor in the middle will probably pick up close to the highest temp of all 16 chips. This is better way than measure in different spot and calculate average. 1 sensor in the middle will actually always read the lowest temp of all the chips MINUS the delta T between junction and Heat sink (could be many degrees C). The BEST thermal monitoring uses one sensor per chip, and always makes critical decisions (like over temp shut-down) based upon the highest reading - not the average. Just because the average temperature is 'safe' doesn't mean that one hot chip isn't about to explode due to an over-temp condition. Enigma |
