Do you know why they won't ship the rest of our miners while they work out the firmware?

What? Have they stopped shipping?

No, didn't think they had stopped, as per what I previously wrote; I'm no where near the manu facility anymore, i'm in Stockholm flipping a coin as to whether I sort out this accommodation mess, or head back to the UK and sort myself out there.

Dude it's b/c of the Swedish coed's there are no rooms, everyone coming back to uni this past month and undersupply of student residence means Stockholm has even more of an accommodation issue than it's notoriously known for.

Have i just killed the Jupiter!?!

Just setup a new miner. Fired it up and recognized that one front-fan didnt work.

I didnt care cause without the case airflow should be OK. I started to change the setting via the webinterface and then the miner suddenly shut down.

I checked everything and found that the front-fan wasnt working cause a blade was STUCK!

So i "unstuck" it and fired the miner up again but NOTHING happens...........  Undecided

Whats going on???

UPDATE:

Fan is working normal again.

Situation is like this:

I start the miner and everything is OK, i can access the webinterface and edit things.

After pretty exactly 1 min the miner shuts down abruptly...  Undecided




this is PSU fault, i think!

i will try another PSU later

at the moment the miner runs with 3 cards

it doesnt matter which card i deactivate as soon as only 3 cards are applied the miner works

edit: i am using a seasonic 1050 gold

So then you are against what KnC is trying to do?  (Selling ASIC's in general?)
since their incentive is not opposed to their customers/investors.

So you feel KnC's business model is opposed to their customers but are not against it.

I guess I'll stop...lol

I'll start this with a disclaimer. I know shit about Sweden.

But I do know University towns. I'd go to the university student union and check the bulletin boards. There are usually a bunch of places that never see the papers or craigslist or any of that, and they are often cheap.

In Reno and Boise, that was about the fastest way to find a place. When I moved to Boise in '90, there wasn't a place to be had on any of the "official" channels. I found a place in two hours through the above method.

Hope it helps.

Maybe, but on the otherhand I have clothing at home. Warm, waterproof clothing, and more than three days of it, including more than one pair of jeans, and shoes...

This whole 'blame the power supply' story sounds pretty suspect to me.  The power supply can't 'force' current into a board...  There is clearly a board design problem here, and it looks to me to be highly unlikely that any specific known-to-be-fully-standards-compliant power supply would be more likely to cause it, other than simply being capable of providing higher instantaneous current - which is clearly not a flaw in a power supply.

I imagine this will turn out to be something that happens when you do something like turning the power on and off at exactly the wrong cadence, or something like that.  Somebody probably left a necessary diode out of the design.


Correct, and capacitors can't be damaged by having current applied "before they've discharged their load", nor could a PSU force current through one.  Capacitors would be damaged by excessive voltage over their rated dielectric rating, and PSUs are designed to keep voltage constant through their rated current capacity.  

There's a great deal of bad/incorrect information being passed around here.

I'm guessing that voltage control suffers near zero current.

Went back and re-read lots of your posts and still didn't see it, but thanks for the answer(s).   No way I'd get on a plane without first checking out Biomech's suggestion.  Getting on a plane to get clothes?  Really?  Take care.

Same question but substitute Corsair AX860.

Look there's no science behind what i'm relaying as i'm not first hand dealing with any of the cap issues. And i've probably not relayed the exact broke English/Swedish version I was told by one of the engineers present. But for sure the fact is every blown cap that has been set back via RMA has been using a Corsair HX850 to power it; and it's the one consistent link, and Anotherhost.se unfortunately were running all their hosted boards with that power supply and have had to switch.

It's only to the UK, I get to sort out more than clothes obv. but clothes are def a limiting factor when you packed for 3-4 days. An E111 card would also be of use, maybe actually telling my friends and parents in person what i'm doing might be considerate as well, seeing as I was like; "checking out Sweden again, back in a few days", or words to that effect. General admin with other bits I was working on, loose ends that need tying up, etc.

(..) Fact is part of the reason they were able to demonstrate a working device so promptly based around a chip with minimal post fab refinement so it can be in your hands asap, is that there will inevitable be some refinement required. What they’ve achieved so far is incredible. This post refinement period is typically 12-18 months, not 24 hours. We all knew margins exist to ensure these devices can be in your hands asap, the 8 DCDC -> 4 DCDC boards is evidence of that. The additional voltage regulators were a now unnecessary overcompensation, and turning off 4 of the modules as you have observed means far less wattage consumed.
(..)

Great achievement - Cograts :-) Well done Bitcoinorama and Knc team!

Yes, at zero current, voltage is zero - from Ohm's law E = I/R.  Happens when you turn the switch off.  Otherwise, the PSU itself draws enough current to keep the constant voltage regulation circuitry regulating a constant voltage.

So you feel KnC's business model is opposed to their customers but are not against it.

Think about it; their incentive is (pre)selling as much as possible for as much as possible. Selling more means increasing network hashrate,  screwing their previous customers, particularly the ones that havent received their goods yet (you ordered BFL, you know what I mean). They cant even really control the speed of this, since whatever they dont sell, KnC's competitors would sell, and then some. Thats just the nature of the beast, not something I blame KnC for. Add to that the fact that asics cost next to nothing to produce, so the price will just drop proportionally to difficulty for a long long time, and you can easily predict what will happen. Ever cheaper asics, ever increasing hashrate (at least until we get somewhere near marginal costs) and miners crying their tears out. Its gonna keep happening for quite some time.

IN theory KnC (or anyone else) could have priced their products not according to their perceived value, but according to their costs, from the start, spreading their NRE over far greater volumes from the start. But then you are asking a for profit company to forgo enormous profits, taking the risk of not recovering the NRE and on top of that, demand would have been so astronomical that they could never have delivered anyway.

Bitcoin asics are a weird market, I dont blame anyone for the dynamics of it, there never was a solution for this other than profit (and risk) sharing arrangements with the vendors, asicminer style.

ANyway, if you want to continue this discussion, we should do it in another thread.
