Just checking in to see how things are going? Do you still think you will have samples up and running by the end of the week?

Even if you use Bitcoin through Tor, the way transactions are handled by the network makes anonymity difficult to achieve. Do not expect your transactions to be anonymous unless you really know what you're doing.

They're coming along slowly. The work on the high current DC/DC supply is progressing much slower than expected, so it's holding things back in some ways. Other aspects of the design are being worked on, and some work has started on the next revision of the board. |

Just a bump to push this one back up.

Slowly, but going decently. We're talking to the chips, though we're still working through a few issues communicating with a vanilla build of cgminer using the BFL communication protocol so we can live hash on the network. Rewriting the mess of firmware BFL released is a bit slow going, but it will definitely be worth it once it's done. I've moved on to now working on the design and layout of the 8 chip board so we can get it sent off to fab. |

Thanks for the updates, really looking forward to the boards. Now if we can just get BFL to hurry up.

I've been waiting over a year for my Singles.  |

And we're hashing. There some interesting things that are coming out in hashing, I'm really excited to push the chips and see how they react even if they are the dregs of BFL's barrel.
In other notes, other features are looking like they should be working great. It appears that the on die thermal diode is functional, so we should have per-chip on-die temperature measurements, which will be much more accurate than a thermal sensor just placed on the PCB.
The latest board revision is almost done and should go off to fab this week. The major changes are dropping the onboard external clock generator which we aren't using, as well as moving to 8 chips. It will also feature a major revision to the power supply to solve some problems and ensure it's exceedingly stable.

Great news! Let's face it, complaining about delayed BFL chip delivery won't be as much fun without having some cool boards sitting around!  |

Probably should put something here.... Maybe an LTC address?

No. We're using a completely different MCU, and the hardware is very different. Some features (like the temperature diodes) require additional support circuitry that isn't on the BFL boards. |

Fair enough, hopefully we'll see some of the innovation eventually merged back into the BFL firmware, if anyone has time to write the code! |

I'm curious too. Did you got engine 0 working. I'm pretty sure it is a hardware problem but still interested if I'm wrong...
