Topic: BitForce SC - release notes (Read 12995 times)

True, I was just thinking of the el cheapo motherboards where they might put a 1.5 amp fuse on it to look good on the outside, but it won't actually run that much.  At least, I've seen similar things happen on other cheap electronics.

Is a fuse for a USB port typically only for one port or two?

Else it's pretty fucking useless fuse!

 

Motherboard designers are not dumb. If it's fused with a 1.5 Amp fuse, the fuse will blow before the trace burns through or the motherboard incinerates. That's precisely why the fuse is there in the first place.

Are the thin little circuit traces on the motherboard also capable of delivery that 1.5 amps though?  You could burn out a trace going that far beyond spec if the manufacturer didn't account for it.

On a typical motherboard, a USB port is fused with a 1.5 Amp fuse.
Plenty of headroom.

RHA: or BFL will perhaps use a "Y" USB cable to draw twice the power, like some USB optical disk drive do: http://www.cyberdata.net/products/cables/specialty/images/usb-b_2y_usb-a.gif This would allow 5W for a Jalapeno, or 700 Mhash/Joule...

Several days ago the USB Promoter Group announced availabity of the new standard - USB Power Delivery:

100 W over USB...
Now we know what BFL had to wait for. 
100 W rated Jalapeno could be quite a powerful coffee warmer... Boiler?
And one could say the requirements of 1143 W for Single SC and 28.5 kW for Mini Rig SC are far more realistic than before... 

AFAIK, there are restrictions shipping to Cuba, North Korea, Iran and maybe one or two others.

There are no restrictions regarding shipment to croatia.

how can i know if i can order something? would be stupid to order and pay and not to recieve..

can i get some assist please?

thanks

Hmm I guess two things that no one seems to factor in is that there is a limit to how much BTC is generated per month that gets given out to everyone on the planet - and also how much of that can be cashed in without killing the price ...
Though, BFL themselves seem to factor that into how they are doing this

Lol, JJ, continuing on your ranting as always.  If you don't like the company, don't buy from them.  Why do you have to crap on every BFL thread you find?

Your numbers make no sense, and you're basing them on a huge number of assumptions, not the least of which is that because the first SC order is X and the last is Y, there have been X-Y SC orders. How many of these do you think are interspersed in their order book from the mad rush at the start?

Put it another way, 108TH with a 3/30/67 Jalapeno/Single/MR spread would be $3.4M. Ask any small business owner how easy and quick the transition from being a $500k/year volume to several million, and then reevaluate how likely it is that BFL will be able to push out $3-4M in product in the span of a few months.

I should start another bets of bitcoin on whether the network hashrate will be over 100TH/s two months after BFL releases their ASICs. It would be interesting to see how many bets and how large are placed on each side.

The problem in this whole thread is that no one knows what the hell will happen because of the company everyone is dealing with. THAT is the truth whether people want to hear it or not.

200 emails are too much to deal with based on hundreds of thousands of dollars in orders?

I'd love that f'in problem in my business. Hi, yes temp agency, please send me ten people at $20 per hour for a few weeks please.

I answer, in detail, at least 20-30 emails per day myself in my company, plus another 20-30 personal emails. This doesn't take me more than a couple hours AT MOST.

Jesus, when are people going to at least DEMAND the customer service they deserve? Has there ever been anything like this where people are willing to throw thousands at an unproven company with a terrible track record just to make a few bucks?

I think that's called gambling, which of course is what everyone is and has been doing with BFL.

Look at the current mini rig trap for example. 15K product which will be obsoleted by the same company you purchased it from in 3 months and you STILL don't even have the damn thing yet.

They have already had your 15k for how long? 3 months at least? You don't think you funded their ASIC, which is in turn going to bite you in the ass unless you give them another 15K to hold onto for three months?

WOW, no wonder people called me crazy in my thread about how ASIC is not the same as previous gen mining technologies. Yet I am now seeing the same arguments I made being used by MANY BFL customers in this and other ASIC related threads.

Free Market, yep, that's the answer, even without nearly ANY information to make an informed purchase...Brilliant.

I sincerely hope this all works out for some of you, best case, many of you. Unfortunately, if you look at this objectively, a train wreck is on the horizon.

I don't care about mining anymore, I've made that personal choice, but I DO care about the future of bitcoin and would LOVE to see a petahash network we can all work off to increase adoption.

Mining is just the birthing phase for now folks, but if the baby is born with two heads...

Let's check in on the data we have so far:

https://bitcointalksearch.org/topic/what-asic-did-you-order-89538

^ at least 168 Gh/order.

https://bitcointalksearch.org/topic/wait-list-bfl-sc-pre-order-information-monarch-orders-too-89685

^ 215 Gh/order. At least 1152 orders by last reported.

1152 orders x 215 Gh/order = 248 Th ordered so far.

1152 orders x 168 Gh/order = 194 Th ordered so far.

And going with the claim made that BFL suggested the first shipment was getting filled around 500 orders or so:

500 orders x 215 Gh/order = 108 Th in the first shipment.

500 orders x 168 Gh/order = 84 Th in the first shipment.  

I'm hoping both these estimates come out too high, but regardless it's clear that difficulty is going to ramp up at an insane pace.

It would take 120 minirigs to 10x the current difficulty. How long do you think it will take BFL to ship 120 minirigs (or 50 MRs and 1750 singles)? Alternately, 120 minirigs is $3.6M at current prices. Do you think BFL has almost four million worth of preorders?

It would only take 12 minirigs to double the current difficulty.  It'll rise 10 fold very quickly, just based on the fact that there's 800+ orders.

I basically agree. Difficulty will probably go up 5-10x with the first shipment alone.

Do you really think that difficulty rise 10fold? I thought it doubled....

If you go back and read the post, he's not talking about the older singles. He's talking about what the SC singles would make at 40 Gh/s when difficulty is 6.8M and the block reward is 25. Here's the passage in full:

"I think the initial deliveries of SC will be quite profitable for awhile, if for no other reason than BFL's ability to deliver them. Even if the singles do 40GH/s, it would take ~425 of them to double the network. Let's say the ship 425 at the end of October in the first batch and that at that point the difficulty is about the same as it is now, as is the price. Within a couple days, difficulty doubles. If no other singles ship out for two weeks, even with double difficulty that single would pay for itself in 2 1/2 weeks. Now imagine they ship 425 more in November and 425 more in late December. The block reward halves, and difficulty is now 6.8M. Difficulty would probably be lower as GPUs shut off due to being unprofitable, but let's run with it. Each single is still earning almost 3BTC a day, and the November ones are also paid off."
