All quotes from BFL_Josh, 29th Mar 2013: http://www.reddit.com/r/Bitcoin/comments/1b8hvt/bfl_josh_updates_on_asic_status_full_transcript/

Performance: "If the cooling becomes an issue, like I said, we'd scale it back and ship multiple units."
-> there goes another one of BFLs promises down the drain: the superb overvlocking ability


Power consumption: "... it's not 1w/GH and we're trying to locate the source of the power drain. It may require a revision of the substrate and/or the PCB."
-> it seems batch #1 and #2 customers get nothing more than a prototype because some major corrections/redesigns might be necessary for the next batches


Guinea pigs: "... I'm thinking no one is going to care at the moment they just want to hash. Which is why we'll be shipping and then improving as we go."
-> Yeah, that's what cowboys do: shoot first - think later


Prototype: It seems BFL finally managed to get something like a prototype up and running: https://www.youtube.com/watch?v=4C4bgho5JSI
Originally advertised values for a Single SC: 40 Watt while hashing (at 40GHash/s).
Actual values for this little prototype board (with unknown hashrate): 42 Watt idle (!!), 160 Watt when hashing


Stability: "We are trying to nail it down. We have some boards at 1.76w, some at 2.5 and some at 4 and one at 6 ... What's causing even more consternation is the fact that the wafer we burned for tests runs at far less power than a second wafer we mounted on the BGA package... so it may be a wafer by wafer thing, and since we only have two datapoints, it's hard to nail down the issue. We're rolling the other 4 wafers off the line shortly (they may be done already I think) - and that will at least give us an idea of the power consumption between wafers with 6 data points."
-> unpredictable behaviour of the devices (intermittent errors, the worst that can happen in engineering, because it makes it especially hard to track down the source of error)


Long-term testing: Unknown. The devices might run fine for years - or blow up after a few hours. No one knows ...


Good luck with that, batch #1 and #2 customers! To reach break even in a reasonable time your ASIC devices have to run stable 24 hours a day, 7 days per week. Or at least don't blow up due to overheating after 10 minutes ...

Nightly News Headline: "Bitcoin miner burns apartment building down due to over heating chips in a device designed by Butterfly Labs."

Is it worth it guys?

Haha, you guys are just two fucking losers. No matter what BFL does, there will be a new thread full of shit with you two assholes running your mouths.

And no matter what BFL does to its investors you will be there to lick their balls and help get people on the scam-band wagon.  :D

Edit: Yes I am a loser that was able to make over 2000% gains by using bitcoins to buy litecoins and trade back and forth, while you suckers wait on BFL's every word like they are god. lol so fail...

That's very sad. BFL is such a reputable company serving their customers with a top notch customer service and still some people publicly rant on them  ;)

Favorite quote from the video:

"It's drawing 160 watts, the power regulator is only rated for 1/3 of that. But don't worry, the next unit will have 2 regulators."

Time to pick up a few fire extinguishers!

Now you have me a little worried.  I actually thought they would be shipping in a week or two.  Can anyone tell me if this has to pass UL certification before shipping?   Since it is made in the USA I would assume it would have to (since even my desk lamp that cost $9.99 at walmart has that sticker).    How long does that cert take?   Surely, it does not just take a day or two?

Honestly, with BFL's track record of keeping promises...I would get a refund, buy bitcoins, or order an AVALON.

BFL isn't going to ship anytime soon.

I just image Josh having to pay the UL office a visit  :D

UL clerk: "Please sir, tell me something about your power supply."
Josh: "It's drawing 160 watts, the power regulator is only rated for 1/3 of that. But don't worry, the next unit will have 2 regulators."
UL clerk: "Um ... next please!!"

+1

I most certainly hope this is the case. That way the first preorders aren't the customers screwed the most by power failing units that consume 2-3 times their rated amount of power, while customers who haven't waited as long automatically get upgraded units. If they could do a "trade in 2 rev 1 boards and get a rev 2 board" deal, I'd love to see that.

Hmm....

160 / 3 = 53

53 * 2 = 106

Which other regulator is going to provide the missing 54 Watts?

The one already on there? It was designed for 60 watts, so I'm assuming they can cover at least that much. It's the excess over 60 that they have to work about.

No.

"the next unit will have 2 regulators."

So where is the missing 54 Watts coming from?

The UL certification is not required by the federal government, but many municipalities require it, thus it's prudent that BFL supply it to be compliant in those municipalities otherwise be fined.

It's the FCC regulations that must be stringently adhere to, of which Josh adamantly claimed they were awaiting results back in a couple weeks back in September, for the FCC was still testing the units that weren't even built yet. To date, they still don't have a working unit to send out for testing. But, once approved, any changes to the units must be re-approved, whereupon new labels are made and need to be affixed to all units, of which can be handle at the rate of 500 per day by any autistic employee.

You aren't hinting that BFL/Josh lied to us, are you?

It doesn't even matter anymore. Avalon didn't have to go through all the regulations and red tape that BFL does. Heck, even our gov't agencies are very slow to process anything. If anything, BFL has to overcome even more obstacles here in the USA compared to Avalon in China.

BFL_Josh: "If the cooling becomes an issue, like I said, we'd scale it back and ship multiple units."


60GH/s!!! Has anyone seen this device? Me wanna buy!  ;D

He wouldn't! Would be? He couldn't! Could he? >.<#

My bad! November 3, and not September.

How to know that Inaba/BFL_Josh is lying:
(a) when he opens his mouth.
(b) when he uses the term "in two weeks".

it is better to fix power consumption before ship rather than that, because anyway if BFL ship thousand of SC only vga affected, asic not :D

now we know they have prototype it means their product is real

sr 4 my poor english

So... with some out in the wild... any earth shattering Kabooms yet?

Be nice if people that post follow up.

Why are you reviving all these dirty old threads?

Because he is on a holly resurrection crusade.

Oh?  Well he should carry on then.

You guys are so silly. Do you see an FCC cert on an Avalon? Do you see a UL cert on an Avalon? What makes you think an Avalon has less of a chance of burning down a house than a BFL?

Maybe this here? https://bitcointalk.org/index.php?topic=160406.msg1706353#msg1706353

(in the meantime BFL changed the casings because of cooling/heat issues - now they have two of those heatinks that are shown on the left)
