@ Phoenix

Most residential AC has 2 phases/legs installed.

All you need to 'make' 220 is a doublewide breaker.
(the phases are staggered and every other breaker is on same leg)
Exception is 3 phase industrial panels where it is every third breaker.
In fact most double wide breakers are 2 single breakers screwed together with the switch levers connected.

If you have a voltmeter and long extension cord you can prove it to yourself.
Just plug in the cord and measure from cord hot to outlet hot.
(hot is small prong/hole in US outlets)
Same phase, hot 2 hot = 0 volts.
Different phase, hot 2 hot = >220 volts.

The main REASON a miner would insist on 220 is efficiency.
A >220 PSU is often 10% more efficient at making 12VDC (depends on model)

I'd guess you have 220 and don't know it.
I don't claim to know what service is installed in Volcano, HI. though.

If dogie's guide is supposed to be some measure of trustworthiness, then surely doing something that fucks all your customers - past and present - to line their own pockets is about the biggest mark of manufacturer untrustworthiness there is? They should have been right down to C- or D immediately.

With frankenjup and withholding neptune refunds for months, knc should be right down at D- or lower now.

B+ is way too high, agreed. If they were selling any other several k$ computer hardware they'd already be bankrupt from all the lawsuits resulting from shipping disastears of first gen miners and the frankenjups.

As someone who isn't an obvious shill or troll,  I also agree.  The 2-1 thing and extra neptune being exclusive was outright deceptive.  
Oh yeah, add that to the list too.

Or not, since they let people switch back who had signed up for the cloud hashing.  Deception requires intent, which you should be fully cognizant of as the prevaricating troll that you are.

Don't do that.  Simply set up the auto-transfer for 1 bitcoin and send your friend 0.23 coins each time you get paid out.

I take it from your hostile response you are waiting on your Neptune to be delivered and are shitting yourself it's going to be a pile of crap you sesquipedalian windbag Grin

I have to agree with this. The lies they told and then turning the customer into the competition. Shameless and pityful.

Mmmm .... Lurked on this one for a while ... and have respect for Dogie with his excellent teardowns ... but KNC surely lost all trust some time ago?

If not ... why not?

Maybe because for anyone who isn't sucking down BS from Avenger and friends it looks like aside from doing a crappy job of boxing products before shipping and having a rather ruthless approach to replacing the damaged gear, KNC has pretty much done everything they said they would, which puts them in rather rare company when it comes to mining equipment.

They made it pretty clear early on that they were going to be building a cloud hashing facility, and that Neptune would probably be their last consumer-grade mining product. Despite the constant bitching in this thread there is exactly zero data to show that they violated their miner protection guarantee during the period in which it was supposed to be relevant. Avenger hammers on endlessly about pseudo-facts like this and then just in the past day has rather hilariously ignored that the pie chart showed KNC with 5% of network hash power prior to the spike as Neptunes were being powered on and shipped.  That was actually what prompted me to post.

If you pre-ordered a Neptune thinking there was not going to be a huge difficulty rise then you were delusional, since at the time that orders first opened it looked as if Cointerra and HashFast were starting to ship in volume.  That they both performed below expectations and the difficulty rise happened anyway thanks to cheaper chicom stuff and various dedicated mining operations (to include KNC's) instead doesn't change the fact that buying a Neptune was a bet that difficulty wouldn't rise too much by the time they shipped. You could argue the Q1/Q2 thing but when someone tells you they'll ship somewhere in a six month range you'd be an idiot to put all your chips on it being early in that range. If you chose not to refund then you made your bed and can now lie in it. I see exactly nothing untrustworthy about a situation in which people are unhappy with the outcome of a gamble they freely engaged.

The people who have complained about refunds seem to either be ephemeral trolls or to simply be unable to figure out how to provide the correct information for an international wire transfer. As this is a situation that could be resolved with a phone call or a short trip to their bank I don't see how this is a trust issue for KNC.

It sounds like they finally found someone who can box things up based on Elenelen's report that the Neptune modules were well packed.

Arguably with 3.3Th/s of performance they have exceeded their threshhold by 10%, and power consumption seems to have come in below the level they stated, so while it's more a motto than anything else, they did in fact over-deliver.

Mine shipped today BTW (I had a late CA order#), and my plan remains the same. Play with it for a while and then probably sell it on eBay if it looks like they're selling for enough. Same for the second one that will show up sometime later. I may well end up with net negative monopoly money but c'est la vie.  I was the one who rolled the dice, not KNC - and I didn't play with money that I could not afford to lose. While I have it, I'm hoping for a decent owners thread since this thread is a train wreck of useless posts by people who neither own anything nor have ever ordered anything from KNC.

Oh one last thing, I think the bitching about the IRS ruling is idiotic. I mean idiotic in the technical sense because it actually opens up some interesting options. If you have to pay capital gains on Bitcoin then the cost basis for the BTC would be the miner plus the electricity. If you mine less BTC than the USD equivalent of your cost basis you've taken a capital loss, which offsets any capital gains in other areas (such investments in more conventional equities such as stocks).  If you achieve positive ROI then you'd owe taxes at the capital gains rate which should be lower than your income tax rate. Or maybe you try another approach and deduct costs for your "hobby business", which under IRS rules means you can deduct costs up to the amount of revenue the hobby business generated, so you could probably deduct the cost of the miner as an unreimbursed business expense up to the USD-equivalent value of the bitcoins you mined.  Since you'd be getting a deduction against your bracket tax rate rather than the lower capital gains rate, this might work out, and the B2B terms of the sales contract from KNC actually reinforce this if questioned by the IRS - you clearly bought it under a B2B arrangement.  Alternately, it is reasonable to straight line depreciate mining hardware to 0 over a very short period, as they are essentially worthless within a year. One could think of this as an extremely expensive machine tool head that cannot be resharpened.

Someone dig out the photo of the knc datorhall for this bozo, so he can see knc totally violated everything they "guaranteed" their customers. And some.

Wow, you demonstrate your stupidity very thoroughly here. They promised not to mine with not more than 5% of what they SOLD, not 5% of the entire bitcoin network.

Sorry for the off topic but when I restarted my October Saturn it just keeps rebooting after 5s being responsive to Ping's ... at the same time it resets the blue light flashes very quickly.

I found that If disconnect one of the asic board from the board the miner runs well with the remaining one. ... I already tried to connect the "bad" asic to other connectors on the controller board but the same thing happens. ...

Is there any logs that I could look to see what is going on?
Does anyone saw this behavior before? The miner was running for ~25 days 24x7 without any issue but now this happened......
Does it mean the board died?

thx!



Sounds like you already isolated the issue.

About all a consumer can do is inspect bad unit visually.
Subdivide and conquor!

Is the ribbon cable installed correctly? (it can be hard to tell on the ASIC end of the ribbon)
Is the heatsink fan spinning?
Is the heatsink still firmly attached to the ASIC?
Has the heatsink been bumped/twisted hard?
The copper heatpipes can become un-attached from the aluminum block near ASIC.
Are the power wires OK? (visually inspect both ends of cable if modular power supply)
REMOVE BLUE EXTENSION CABLES!!!!!!!!!!!!!
(each extension adds 12 possible points of failure)

You could also try swapping ribbon cables since you have a known good one on the working ASIC.
Also try different connectors on the controller board.
 

Hope it helps!

Yeah it's well known what they did during that period, they even pretty much smiled, winked and shrugged it off once it was widely known.

They've pissed and crapped on a lot of people over the months, and they've begun to deliver a seemingly functional product now. There's good and bad.

Ignominious gloating

people, why is it you feel the need to rub salt into the wounds of fellow miners?
We have all been burned at one point or another, and if you haven't been burned then you are either more mouth than money or a god-damn leprechaun with all the luck of the devil in you.

We all understand how to calculate what our own mining rigs will make in their return of investment and whether or not they will break even, so can I just make a plea here; for the benefit of the community as a whole... quit with the ignominious gloating about how rolled-over one or other of us have been? please? It does you no favours to make folk feel badly about our expensive purchases. Let owners of these rigs discuss them in peace.

rant over.


++

 Elenelen you can't simply post a ++ that will get your pos deleted.  You have to type a couple of words as well Wink
Anyway, I believe the rhetoric is directed at would-be buyers to persuade them NOT to buy anymore pre-orders from any company.  IF there has been some wrong-doing, the discussion needs to take place.
 
 I'm pretty sure I read in this very thread that someone was able to get out of their "hash while you wait" predicament because of the discussions about being rolled over.

Got three people saying they have faulty rigs here, so "functional" is yet to be proved:

Yeah, giving away free money you literally stole from people with your datorhall.

It seems the self-delusion isn't just reserved for those buying rigs  Cheesy

Neptune's arrived about five minutes ago - Batch#1 order paid for on the 26th November.

I'll let you guys know how they perform! Even though they are late (very late) I am a bit excited :-D



If it is preconfigured with any pool details I will let everyone know.



Coins per 24h at these conditions 0.1121 BTC
How much did you spend on it


In total 13 BTC at $900 per BTC (inc. shipping / taxes).

I've already bought back the 13 BTC at $500, I'm expecting the miner to ROI around 6 months on its own BTC investment but I also enjoy mining and it opens up opportunities for getting some returns on alt's from time to time.




Sorry but you wont make a roi in 6 months, the next difficulty jump is 13 to 17 so how do you work out 6 months to return your money?
agreed...but...
it's already nearly 30% with 4 and 1/2 days to go....     how'd you get 13 to 17?

https://bitcoinwisdom.com/bitcoin/difficulty
clearly says 28.8



Estimated Next Difficulty:   17,351,720,663 (+28.89%)

the 28.89 is the change from 13 to 17 is how much in percentage
no, 28.89 means the estimated next diffchange is upping by at least 28.9%, period....
soon to be higher
I have no clue where you are calculating this 13-17%?

You really are dense. He means 13 billion to 17 billion not percent.

Oops, late to the party. Nevermind.

And also 220v is slightly very slightly more effective at carrying the power through the wiring as there is less resistence with higher voltage.

The main reason the US has 120 ac is because the voltage cant kill someone as 220 can if they get shocked.

I guess the big question I have for those who have received their Neptune's in the US and in Canada (if there aren't Canadian's other than myself in this thread) did you have to pay duty if so how how much?

Thanks,



 You don't have to pay duty but you have to pay the HST @ 13% of the declared value after converting to CAD which is a real downer since our dollar plummeted against the USD since last NOV.  I've had to pay this one every miner I've purchased... yes I got BFL'd.

As someone who isn't an obvious shill or troll,  I also agree.  The 2-1 thing and extra neptune being exclusive was outright deceptive.  
Oh yeah, add that to the list too.

Or not, since they let people switch back who had signed up for the cloud hashing.  Deception requires intent, which you should be fully cognizant of as the prevaricating troll that you are.

This isn't about if people can change their choice for cloud hashing.  This is about having to make the choice at all.
 
I read the KnC Plan B and 2 for one as being inclusive with each other when KnC brought them out a few months ago.  They only told people they were exclusive once it was too late to refund.  Did you realize that customers were going to have to choose one or the other?  There are people on the KnC boards complaining that they would have refunded if they were going to be forced to choose.

People were also expecting HWYW to go online at the beginning of the month,  as batch 1 was supposed to go out a month before batch 2. Thus,  many people (myself included)  view KNC as being late for batch 0/1.  People were withholding refunds because they felt KNC had good intentions towards their customers.

At the very least, there was incredibly bad communication.  I don't think it is proveable that they were lieing,  but I think if they were a US company and a customer sued them for a refund,  the customer would win.  

You really think I am a troll?  You don't think that is a valid complaint?

The main reason the US has 120 ac is because the voltage cant kill someone as 220 can if they get shocked.

 Line losses due to joule heating are proportional to I2R so if you double the current (which you would with 110V as opposed to using 220V) you quadruple your line losses.  So let's say you have a run of seventy feet of 14 awg copper wire and you run an 1800 watt miner on a 120V circuit.  Your losses would be about 2.5% or about 45 watts.   Run the same miner on the same circuit @ 240V and your losses are about 0.6% or 11 watts.
