Not printing yet, but everything works. Its talking to the software, all the motors work, bed and extruder heating and temp sensors work, all the switches work. Didnt quite expect that from the first time

All thats left to do is calibrating it and tomorrow I may print the first parts although I still havent received 2 replacement bearings so the print quality is probably going to be lousy. Still, Im happy

You might as well have linked them, I had not seen them and Im not sure many here have. So they are here:

Those video's are of bitfury boards, but at least thats a big step up from not having anything to show. Im not familiar enough with bitfury products to tell if thats really a custom PCB or an existing design, but unless someone says otherwise Ill assume they are indeed making their own bitfury boards. Good, major improvement in my book.


Problem is that those claims all come from newbie posters and its impossible for us to tell if they are true.

Is the heatspreader of the chip still flat? If the cooler was actually damaged while mounted, its reasonable to assume the flimsy alu heatspreader got dented or slightly bent too. Its even possible the heatspreader is no longer making proper contact with (all) the dies. I once had that with an AMD CPU, no matter what cooler I put on it, it would overheat, badly. removing the alu heatspreader solved that. Not sure Id be so brave with such an expensive miner where there are 4 seperate dies under the heatspreader, but I wouldnt mind seeing the pics if you decide to try

2-3 months should be considered a realistic minimum between tape out and deployment for normal production runs (ie without paying extra for hotlots) and assuming no serious issues anywhere with either design or supply chain. Hot lots might shave a few weeks off that, but reality usually adds more.

OTOH, if this chip will be 20nm like KnC's latest announcement, it might be considerbly longer. 20nm mask creation is slower due to the need for double patterning, and the whole process is still very new and not as well understood as mature processes. For a 20nm product anything before early Q3 seems extremely optimistic to me. (That also applies to KnC, Im not buying their Q1/2 claims).

FWIW.

Are you blaming government intervention also for inputs.io, labcoin, pirateat40, and countless other scams?
ITs been crystal clear from day 1 that these bitcoin security issuers and exchanges are violating relevant laws in just about any country on earth.

Now you may object to laws that require security issuers to register their shares, make certain disclosures etc, you may think its a good idea that an anonymous entity operating from a phone-boot in Nigeria can legally operate a money exchange and hold millions of dollars of other people's coins with no verification, oversight or accountability, but then you should protest those laws instead of blaming government for enforcing them when someone knowingly violates them.

Personally, I think bitcoin asset market is doing a very good job proving why there is a need for at least some sensible regulation and oversight, just leaving it up to the free market makes it a paradise for scammers and a useless minefield for investors.

Admittedly, securely storing coins is not trivial for non-nerds today, but thats being worked on. Check out trezor and similar hardware wallets. There are quite good reasons why bitcoin hasnt taken over the world yet, the ecosystem just isnt ready for it yet. If you arent able to handle its rough edges (or price volatility), you should just wait. Not everyone can be an early adopter.


You mean like gold and cash are broken or pointless because you cant rely on them not being stolen if you dont secure them ? Its not like paypal and credit cards are fraud free either.

anyway /OT

Bitcoin is working fine. The main problem is that so many people believe(d) that because something is related to bitcoin, that no laws apply and you can just freely break security regulations all over the world, along with violating money transmitter licence requirements and AML regulations.

The "its not illegal because... bitcoin" argument.

If you fell for that, and sent your coins to an illegal exchange believing that is a safe thing to do, its not bitcoin's fault. Not a single satoshi in my wallet has been lost due to scams.

Its not called stealing if its the government doing it.

Nope.
I-techpro (or something) was, but the CEO and sole shareholder of that company denied any involvement, responsibility or barely even any knowledge of labcoin.

Coming from a 2 post newbie who registered yesterday and is not sharing any of the evidence of his research, I hope you will understand this is not going to increase anyone's confidence

In a world of pseudonymous, irreversible currencies, gut feeling just isnt good enough. Countless millions have been lost by people relying on gut feeling.

I dont know whether these guys are legit or not, but as long as there no shred of evidence that they are legit and these products even exist, they should be treated correspondingly.

Riiiiight. Rhyming those statements is not easy.
Is neobee going to introduce fractional reserve bitcoins LOL?

What makes you think they have not even completed the design of the PCB?

I may not be a match for your ability to insult people, but my reading comprehension is just fine josh.

'There's no way a USB cable would support 120v, it would melt almost instantly the minute it touched anything.'


No amount of context makes that statement remotely correct. And in this case the context was that the guy actually measured 120V on the USB ground, he made no claims about any load. When I pointed out how ridiculous your statement was,  you "clarified"

'The guy was claiming that it shocked him and that it was plugged into his Jalapeno and also blew out the rest of his equipment... which would mean the wire would have to carry enough amps to do that, meaning it would melt @ 120v.'


Which is no more correct than your first statement, as common sense and basic knowledge of EE and ground loops would tell you, and as indicated by countless posts on your support forum. Your life threateningly shoddy PSUs are leaking 120V through the ground and to the USB, in many cases frying the electronics and tripping circuits, exactly as claimed in the first post you dismissed as impossible. So now its no longer impossible, or did I misread that too?

Ah yes, no substance, only ad hominems. Tell me Josh, do you still maintain its impossible your customers measure 110V on their USB ports?

Just today, 5 BFL customers reporting their PSU died, killing their miner in the process:

Several more stories here, with power trips and even sparks reported from the USB  port:
"only just touched the port without even inserting and several bright sparks arced from the USB cable to the iMac"

You think those were 12V arcs Josh? Yet strangely, not one reported their USB cable actually melted. But Im the moron right?

BTW no one seems able to get through to CS for an RMA, I guess that couldnt have anything to do with they COO being preoccupied with insulting people on other forums. A man in your function must prioritize.


edit: despite the broken english, this message is pretty darn crystal clear I think:

Problem is in power sources because besides regular output DC 13V 6A (as writen on bottom) passes through also part of AC from power grid. In Czech rep. we have 230V AC in grid and between DC output connector of powers ource and grounding pole in outlet was about 110V AC so about half voltage came through and was grounded by USB ports and ground wire in my PC PSU!!!
Lucky me that PC, three Jalapenos and also three Lancelot miners wasn't fried by these shity power sources...

110V on the USB ground. Where did we hear that before? No molten wires though. Now go tell your customers they are morons Josh, thats what you do best.

Oh I did. And other threads too. You dont have to be an EE to figure out what happened:

https://forums.butterflylabs.com/bfl-forum-miscellaneous/5295-throw-away-your-bfl-single-power-supply-hazardous.html

You guys are shipping fucking dangerous PSU's that are almost certainly illegal too. But instead of tackling that issue you have nothing better to do than make braindead comments about how its impossible that 120V would travel through a USB cable and insulting everyone on every board.

Some COO you are.

Utter bullshit. Even a tiny load can destroy electronic equipment. Even a static discharge. Never seen the anti static wrist bands your employees hopefully use? Static electricity discharges can easily exceed 10000V. But you think such discharge can burn through a USB wire?

But you already knew that, right?  You just wanted to post yet another troll with your worthless, utterly idiotic, mind numbing stupidity.

In short: You're a moron, please go back to your BFL forums with the rest of the idiots and leave the adults alone

After bending them back mostly right, you will still need to sand/lap the bottom. Be careful not to sand it down too much, if that gas in there escapes, its game over. Actually, that may already have happenend if there is only the tiniest of cracks. Ive ruined a fair number of GPU coolers trying to bend the heatpipes on a certain type of cooler to elevate them above some high caps on my cards. No visible damage, but cooling performance was terrible and you could simply feel that some pipes no longer got warm like the others, despite perfect contact surface.
