Single Revision 3

[Cockeyed]

I expect delivery in about a month, yes, that leaves ~8 months... and power cost is 0, since they will most likely be housed in my DC.  But even factoring in power, depending on what BTC prices do, it may be paid off sooner (or later if the fall is dramatic)  I based my calculations on $4/btc.

 Is there a limit to how many you can put on 1 PC

127 per USB port.   I imagine you'd run out of power points before your PC ran out of USB ports

This is the number from the usb-specification, and even if somebody said, it will not require any CPU-Power from the PC and a "healthy" usb-port is enogh, I would not be too sure. Depends all on the amount of data which is transfered and on the latencies. I really don´t know what data is transferred, but if that will turn out as a problem, you could use an usb3-host-port on your PC, together with a huge usb3-hub. That will give you some air with all the usb2-devices. But with just 10 singles you will not encounter any problem. Just my 2 BTC-cent on this...

Anyone have a general idea on how long the wait is, currently, between ordering and shipping?

Go here and draw your own conclusions:

No one can tell you what the current wait is, not even BFL. People that have ordered in mid-December have started getting theirs (some have, some haven't). People who ordered in early January still haven't received anything. It isn't yet clear whether BFL is now catching up, keeping up, or getting further behind. As for how long will people who order now have to wait, your guess is as good as mine.

[P_Shep]

Probably on the slow boat from china now.

[abeaulieu]

Ordering now is probably after rev 3, unless BFL steps us their production size big time. Which they certainly should, considering that most people's reservations in ordering the singles is how long it would take until it gets into their hands.

[Cablez]

I have had my orders in and it is looking like I may be getting the rev3s??  yeah!!     ;)

BFL really does need to get themselves together though and get me my unitz.  Can't wait for the end of the month.......

[abeaulieu]

I'm surprised they are still keeping their 4-6 week ship guarantee. I wonder what they're backing it with...

[DeathAndTaxes]

If they don't meet the 4-6 weeks you can cancel and get your money back ... guaranteed.  There is nothing else "backing" it.  Not a single person has received units in <6 weeks.  Some early January orders just shipped.

[abeaulieu]

Some early January orders just shipped.

Awesome. Seems like they're making some good progress. I hope this indicates confidence in their design such that it will accelerate the order fulfillment.

[Inaba]

I'm not seeing where they are claiming 4 - 6 weeks on the website anymore.  Beyond that, I don't recall them ever guaranteeing 4 - 6 weeks, just an estimate... though I may be wrong about that.

[Cablez]

I believe the 4-6 week statement was on the order form no?

Actually I don't see it anywhere now. Hmmm

You can see it on the order page for the Singles. They use the word 'guaranteed'.

Look at the 'Order Terms' section on the right side of the page, above the photo of the old Rev 1 Single PCB they are no longer producing.

[abeaulieu]

When you get the confirmation page after placing an order (through Paypal, not sure if other methods get the same page) there is a block of text:

Delivery: Units are guaranteed to be shipped within four to six weeks from the date of purchase. However, your delivery time may be significantly less depending on the production group your order falls in.

[Inaba]

Ah got it, I missed that... was scanning for 4 - 6 instead of four to six heh... oops!

[Cablez]

Your not alone Inaba, same here.  Doh!

I assume this is a special processing unit built for Bitcoin mining? You just plug it into a USB port and you are good to go?

I suggest you do some more reading before posting.

Maybe newbies jail should be extended from 5 to 10 posts...

Actually, he is quite correct. It is a FPGA(google that term), built specifically for SHA256-hashing, or Bitcoin mining in this case.

Of course he's "quite correct".

Are we in the mode of stating the obvious now?!
That's _much_ more annoying than simply stating "subscribe".

You realize that this is the newbie board right? I reserve the right to act like an idiot.
