Shouldn't this be called "Project #2.5" now? (Or 3  ) |

Can anyone become a "merchant" or does there need to be an ecommerce site? This is because for someone in the U.S. to send money to Mexico going through Bit-Pay for the cash out to a bank in Mexico at a 3.99% fee is now competitive with the least expensive money transfer alternatives. Here's a recent report with some price comparisons: - http://www.consumerreports.org/cro/2012/03/the-best-ways-to-send-money-abroadPretty sure anyone can sign up, brb going to try it. NVM, not really. |

For me, the answer to deal with the problem of "what do I do when the hot tub is already hot enough?" needs no valves: it is a software solution to simply lower the hash rate when the extra heat is not needed. Given that the original purpose is to mine with free power, there is no point in using more power than the hot tub needs for heat because that power is no longer free.
That makes it real simple then, just a couple pumps, a heat exchanger and a temp sensor with communications to your computer to control it. |

The internal protection in a PSU will not allow the output voltage to go out of spec, I.E., it will never be above or below its rated output. Therefore a "brownout" cannot happen on the 12v side, but such an event on the input will simply cause a shutdown.

I have never seen a high quality PSU kill downstream components unless abused or pushed beyond specs. Honestly I haven't ever heard of any ATX PSU damaging components that wasn't related to user error or abuse.
+1, also insurance. |

So I drew this up for fun. Uses a 4-way ball valve, which you might be able to get an electrically controlled version of and make the heater automated. This drawing shows the use of an external radiator in case the tub is too hot.  Maybe someone knows of some way to make this same idea, but with some kind of continuously variable valve. That would be the best thing to do. |

Does anyone have any actual numbers on heat loss of such a tub? How much can I expect one to dissipate?

Very nice. I never considered using the EPS12V connector, because you could use it for a host system such as a cheap atom or VIA based mini-ITX board. And, if you are powering FPGAs other than BFL, you could even use one of these: http://www.newegg.com/Product/Product.aspx?Item=N82E16812198016 for a total of 12 6 FPGA per 6-pin connector. (edit, brain dead, said 12 meant 6) |

Yeah, I am not looking forward to that... it is almost tempting to just cut the ends off and do some soldering.
Yeah I am thinking that is the better route for hand assembly. Doing 6 butt splices would be a lot easier than building a cable assembly by hand. Well hey, I just found this thing:  That would cut the amount of work needed by quite a lot. You would only need to buy barrel adapters, and then there would be no PSU hacking needed. I might even do some, since gigavps offered 4BTC each how does that sound for everyone? EDIT: This one would allow for 3 BFLs per 6-pin, and if you need some, say how many so I can figure out how much stuff to order. |

Interesting address, is it really all in uppercase? |

So, did you send an email?
We have no concrete proof of any abuse, do we? |

*6 million scovilles...
Jesus. Did you just dip some peanuts in some pepper spray fluid? That's hot! |

Achievement unlocked: 3.3v. Even though the eBay seller sent me 12 AWG, I decided screw it, I'll use it. It doesn't match the 14 AWG for the rest of the connections, but meh it fit the spade terminals. Next is to find some 26 24AWG 20 conductor cable for the signal connection. EDIT: Hmm I might have a parallel cable laying around somewhere...  |

Make an animated version with some guy pumping the tail up and down like a pump handle and coins shooting everywhere. Add flashing text to say MAKE YOUR OWN MONEY, and then post it once or twice to some *chans. Don't forget a small logo in the bottom left and a short link to something similar but with a better explanation, using something like bit.ly or whatever. |

BAMT won't OC one of my cards. I have 4x5870 in my rig, all works 900/300 and 413MH/s, but now one card went to 374MH/s and i didn'i change bamt.conf. How can i repair this problem?
It most likely got flagged by "mother", that's the routine that helps keep things in check and stable. So for example, if a GPU hangs, it will disable OC and reboot to keep you running. See if there is a file in /live/image/BAMT/CONTROL/ACTIVE/ (It will be something like noOCGPUx, x being the number of the GPU that borked) If yes, then remove it. But you this means your OC is not stable and it will happen again so drop you current numbers. Thanks for the tip, same happened to me. Only problem is something is wrong with my rig so that it hangs on reboot, requiring a power off to correct. So the auto reboot was annoying. |

It's reasonable to assume that if any alternate currency were to really become popular it would get the negative attention of TPTB. Think about it: one day the USG starts to notice an unexplainable drop in revenue. They start digging to find out the cause of this anomaly and find a growing underground economy with a non-USD currency.
For crypto currencies, agencies with lots of computing power would become heavily involved in the effort to try to disrupt or destroy it.
It's what would happen if BTC really became mainstream.
i fully acknowledge that there may at some point be some negative attention given to bitcoin from the US government. i laugh at the idea that at this point, right now, bitcoin is seen as such a threat that billions are invested to "crush it". +1 |

You're right, but paying double price for a few more % is ridiculous at least (I'm talking about Platinum series PSU's)
I'll just leave this here: http://www.plugloadsolutions.com/psu_reports/DELL_D750E-S2_750W_SO-386_Report.pdfThe one and only Titanium rated PSU, at better than 96% efficiency. Can't find it for sale anywhere, but I wonder what it will cost in a few years when it gets removed from decommissioned servers. |

If it's a botnet Im fairly sure I will have confirmation of it within a few days, the "active researcher in a major company dealing in antiviral/security-software" I mentioned contacting a few pages back in this thread is actually prettymuch the "biggest star" in he's line of work: I got Mikko H. Hyppönen, the Chief Research Officer of F-Secure to look in to it. As soon as I have more I will be posting here.
Even if you don't use or even like some of their software, they have an excellent if not the best team of researchers. The same applies to some other well-known vendors such as Symantec, who also have world-class teams. |

It's usually a couple percent less than the best it can do. And the best it can do is usually with around 70-80% load. If 2-3% efficiency is a lot for you, then you should buy Enermax Platimax PSU, and run it on 70% load - you should get around 94-95% efficiency.....for a hell of a lot of money, it will pay out when your grand children get their mortgage paid out.
This is true. However, that 2-3% efficiency shows up as reasonably substantial additional heat which a) can reduce the expected lifespan in the case of cheaper PSUs, and b) must be dealt with on the cooling side of things. I tend to think in datacenter size proportions, so I consider efficiency carefully, factor in lifespan and ease of replacement, and sprinkle on some actual cost later. This will not usually apply to most users. |
