So, what do you do, after (hopefully) receiving your Avalon unit, it (suddenly) stops working (properly)?
It seems like it has an ATX power supply, fans, an USB hub, 3 ASIC modules, and a ARM based controller.
If power supply, a fan or the USB hub break, no problem, go buy another, replace and you're back in business.
If an ASIC module fails, given the fact that the unit is modular and expandable, it has a good change to work with only 2 modules. Maybe Foundation (or Jeff) can help with a 15 minutes test, disconnecting one of the (hot glued) USB cables between USB hub and one of the modules? 44GH/s is better than nothing, until a replacement part arrives.
But what if controller fails? Disaster! Maybe there's a possibility to put the firmware (or part of it) on a wireless router (w/USB) with the same chipset? Any idea anybody?

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.

there does not seem to be any warranty explicitly stated on the avalon website.

Yes but on one hand, every day of non-functioning costs you money. On the other hand, as REGULAR said, it's unclear with Avalon guys. So, I'm more interested of what can be done by yourself, at least until (hypothetically) you get your replacement parts. |

The term Buyer Beware has never been more applicable than when dealing with avalon.

It's just a WR703N with some custom firmware and an external antenna connector soldered in. If someone would be so kind as to rip the firmware from their Avalon and post it, I think I can use the openwrt toolchain to build from it a firmware bundle that can be flashed onto a factory WR703N. I'd be more worried about the DC-DC converters failing. No offense to ngzhang. |

I think DC-DC converters are on each module, so a failure will kill only one module, not the whole unit. Even this is depending on how a module reacts to a partial failure, be it a DC-DC or an ASIC chip (probably are multiple DC-DC per/on each module). |

Now I notice there's probably another module each ASIC module connects with a ribbon cable to.

Easy. Buy replacement parts or buy another Avalon. It's not like Avalon offers a warranty on their "no refund" devices  |

Got the DSO, DMM, soldering iron, and cheap microscope.
No hot air gun yet.

Do I really want to do business with a company that soooo drops the ball on communication? Silence is NOT golden in this case. Sigg |
