Are these guys real? Want to buy some Sony Entertainment Network cards... Yes very real  Ok, thanks:) |

Now orbiting Australia... ORB has just been enabled on Bitcoin Gift Cards https://bitcoingiftcards.com.au/.  Although it won't show up in the list on the site footer just yet. Are these guys real? Want to buy some Sony Entertainment Network cards... |

Price is down, miners turn off their machines or sell them when that happens.
Wait for the firework when one of the big boys goes belly up... |

I almost missed this great company. At the first look simple memory producer, at the second look there was much more. Swissbit cards offers high security and even eliptic curve encryption.
Looks great. Where can I buy one? |

I would still be vary careful dealing with this company; -- We are a bit new here, aren't we?  |

lol i got just over 1 gh/s cloud mining and for the past 3 days my btc balance barely gets above zero then plummets back down to negative btc. There is no way i would invest at this time, not till btc prices goes back up..

Same here. I have almost 200 GH just for fun, balance is below zero for days now. No idea what is going on. Sometimes I point my own miners to ghash to cranck up the balance a bit;) |

LOL:) Can we cangtip already at bitcointalk? |

I see a whole sheet of private keys for casascius coins in that video. All fully readable!  Sheets of 22-character codes that were discarded from Series 1 which had the misspelling in the hologram... Series 2 and beyond have 30 character codes. I hold my misspelled coin dear... |

We as the Zeta Mining team will actually prove that FGPA based mining hardwares may be capable of competing with the latest ASIC miners. Follow us!
Please do the math for us: cost and power consumption of the FPGA vs expected hashrate. Think we are done with this thread rather quickly then. |

Lijkt erop dat de BTM bij de Waag in Delft out of funds is. Althans dat meldt de machine:  Maar er zou nog genoeg btc moeten zijn als je het wallet address bekijkt:  Hopelijk ziet de operator dit en wordt het gefixt... intron |

So it seems the ARM can be powered from
EM field. Willing to share the part number of
the NFC chip?
Yes, the microcontroller can be entirely powered from the EM field produced by the NFC reader, and it can draw enough current to perform elliptic curve operations at a reasonable speed (currently about 1.5 s for a multiplication and I think this can still be improved). I'm using the AS3953 chip from AMS. It sources up to 5mA at 3.3V for your external circuitry, but in practice if I draw 3-4mA the voltage falls closer to 2.5V. It's a bit tricky to get this chip working because you'll simultaneously be debugging the reader side and the target side, so let me know if I can help. I'm using an "Energy Micro" Cortex M3 from Silabs, as these have good efficiency and very low sleep currents. With no LEDs illuminated, I'm able to perform elliptic curve multiplication running its internal RC oscillator at 21 MHz powered entirely from the EM field (in the video, I was running the micro at 21 MHz). At faster clock speeds, the device browns out. Thanks a lot, like the details:-) |

Do you support testnet?
No I don't but I could easily set one up on a separate VPS. However these servers do have running costs and there's not much in the way of incentive with running a testnet pool is there? No:) Just asking. |
|

|
|
Thanks for running the pool!
Can check my stratum code
now:-)
