Minor nitpick:

120v x 20A USA You're kitchen might have a 2400w rated socket for your cooker, everywhere else will be 1800w.

Typical circuit spec for a residential electric stove is 240V @ 50A.  That works out to 12 kW.

(Not that you'd rip out the stove and plug in a mini-rig...what are you going to cook on? A campstove?  Grin )

They had to make wild promises in order to get pre-orders to fund the actual development.
Nobody would pre-order vaporware.

Don't forget that they also needed to make wild promises to scare away the still budding at the time FPGA market and other potential ASIC suppliers.

If people had known mid last year that BFL would deliver in 12 months and not 3, I have no doubt there would currently be a healthy FPGA market out there.  

And we'll never know how many potential legit ASIC suppliers were scared away by BFL's promise, leaving only the failed cowboys and Avalon behind.  But I would bet that number is greater than zero.

I don't know if it's possible to quantify the damage BFL have done to the Bitcoin mining environment, but I have no doubt it's huge.

My guess is they had to keep making shipping promises they knew they couldn't keep so they could keep getting "preorder" money so they would have cash to fulfill the return requests. Even if they get an ASIC to work, I would be shocked if they have enough capital to fulfill all of the current orders.

How BFL promised to begin shipping in late October or early November 2012 is beyond comprehension.  All the promises made to date regarding power use and performance have been based on simulations that now have proved to be wildly optimistic. 

I wonder how they intend to ship Jalapeno products.  An extra power supply will be required, along with a case redesign and fans.  They might as well refund customer orders now to avoid the hassle and months of extra delays.

It is pretty obvious now that they don't know what they are doing...  like the first season of Gold Rush

BFL probably filmed the past 10 months and will be on the next season of that show

It won't work unless there's an antagonist in each episode. Only if I had a clue as to whom that would be. Perhaps, if I had a quarter I could hunt one. One with a video camera that plays poker. But what are the odds of such an individual existing? I guess I could dream.

 Mini Rig casings are all garbage at this point

no they aren't - they are the new jalapeno cases!  Kiss

Order your 15 minute fireworks show now*T # + =


* Not an order, pre-order only
T Units expected to ship March 2013
# March means july
+ There are 30,000 orders before yours, don't expect aything before december.
= We've never made fireworks before, nobody here knows how to make them

Keep it Simple. Every Bit Matters.
Glowing red? That rig will be giving itself a rather realistic flame effect on the casing in just a few minutes with extra smoke fumes for a grande finale.

Hmmm... I have 230V @ 16A and 400V @ 16A which is enough for a big welder but could be insufficient for a mining rig. That sucks.

I would really like someone to put up a bet on a date when they will have 5 mini rigs operating in paying customers hands in the USA (really want to see if any BFLers take the other side).   Mini Rig casings are all garbage at this point but if they do not figure this out and ship, they will basically be shipping fire starters and bitcoin will draw the wrath of the ignorant media when some idiot burns an apartment (or dorm) down "mining for millions".   I have ZERO faith they will send anything to UL which could have MO shut them down after they start shipping since most munis do not allow untested electrical devices in their municipalities for this very reason.

It would be a good bet to create, because nobody is going to be able to run a 1500GH/s (now 1250GH/s) Mini Rig SC in their home @ 8000w

120v x 20A USA You're kitchen might have a 2400w rated socket for your cooker, everywhere else will be 1800w.
230v x 13A UK might get up to 3000w max on the kitchen cooker socket. Grin

Many US homes have a 230v x 30A dryer plug.  I have similar plugs for servers though not the same physical configuration.   7200W derated to 80% gives you 5760.   That is about as high as you want to go and of course getting rid of that kind of heat is challenging. 

Ignoring your wiring problems you would have.   Look at the pretty box dimensions.   And look at the fans.   Why paint it black, this thing will be glowing red in a few hours.   It will set your wife's cat on fire.

No idea how many chips are running in the video...

http://www.youtube.com/watch?v=4C4bgho5JSI

...or if the thing hashing 25GH/s in the photos is a FPGA Mini Rig or an ASIC...

...but assuming it's a 4 chip 30GH/s Little Single @ 160w/25GH/s...

1) 4.5GH/s Jalapeño is toast, needs complete board redesign. USB bricks are out. 160w / 4 = 40w/3.75GH/s

2) 60GH/s SC Single is toast, needs an redesign with enormous cooler, and more voltage regulators for 160w x 2 = 320w/50GH/s

3) 1500GH/s Mini Rig SC likewise is going to have cooling, power issues, and require a bigger case for the bigger coolers.
    (If they built it, it would blow your home mains fuses anyway!) 320w x 25 SC Singles = 8000w/1250GH/s

    1500Gh/s could be reached with 60x Little Singles but this would be 9600w!

The chips are ok....it's the board that is the problem....so they say.

They are doing a revision on the PCB & adding "power regulators" or something  Roll Eyes

Congrats on the "devil" post #666  Cheesy

If that was the case, v2 would be so incredibly superior to v1, the first buyers would be completely fucked over.

On the bright side, it doesn't seem true at all. They have this habit of over-promising and under-delivering.

Could it be that they had top change the specs of the chip (from 65 nm to 90nm or higher) while they switched to FCBGA?
