This, this and more this!!!  Please be aware of which connectors you are using and use only separate 'lines'.

Too much current through those paltry 18AWG wires will burn them out!!!

With a name like 'Cablez', I'd presume you're the expert!

 

Seems he really is

10 slots at 15BTC each (will reach it probably) = 18K USD
I wish I was the owner if this forum

Don't worry, theymos will tell you it costs at least 10k/month to host this forum. (lol)

Don't worry, the projected US$660,000 per year in ad sales will cover that.  The words MONEY GRUBBING and DISCRIMINATION comes to mind. The words COMMUNITY doesn't.

Anyone know how much the guy offering to triple your BTC paid for his slots?

What exactly is it that you don't like? They probably took in well over $10m so far in orders - even they spent $100K on advertising, that couldn't terribly affect the customer price per unit - probably less than $20/unit.

I don't like too much seeing pre-order based companies spending big amounts of their customer's money (which have not received any device yet) to suck in more pre-order customers. It's not illegal, its not unethical unless there are huge delays, as per BFL, but honestly I don't like it.

Plus, +$1,500 for a weekly slot on this forum is simply retarded.

No doubt Asics are going to get cheap as hell.  It's just like the microwave, cell phone, and plasma tv all over again.

So any word on script for these beasts?  Probably not.

Edit:  Just read last page, nevermind.

[islandsound]

So what is the bottom line with this company?  Does everyone feel they are going to turn into another BFL debacle?

I've spoken personally to a couple people now about their dealings with TerraHash as well and it's not favorable at all?  What is going to happen, people like Intel and Samsung coming in and crushing all the small time players?  I am just looking for my small piece of the pie here.

Just buy bitcoins then. Or buy from a company that has stock in hand already, like bitfury. If you want to take a risk and invest into a pre-order I would suggest going with KnC. Also make sure you check out http://mining.thegenesisblock.com/

Max efficiency at 0.6V out w/ 12V input - 84%
Max efficiency at 1.2V out w/ 12V input - 90%
Max efficiency at 1.8V out w/ 12V input - 92%

And the whopper, 1.5ms typical rise in output current from 10% to 90%.  Not very responsive for such a small converter, esp for switching at 400khz.

And did you see that ripple voltage? !!!
Oh my gosh, between 8-20mVp-p at 1 volt!

It's too bad they couldn't use 2 of them at once.
It's too bad they don't have a SYNC function.
It's too bad the SYNC function couldn't be programmed to reduce ripple by interleaving.

If only there were such things.

Oh wait.....
They do have those functions.

Gee I wonder if the KnC guys noticed or it was just coinkydink

It's too bad the pdf you linked didn't include examples of how to deal with the known limitations.
Oh wait.....

All DC/DC converters have limitations.
The efficiency is not bad. It's 80+ and that's DC/DC at 1/12th supply V.

An engineer could design better given enough time and money.

But (there's always a 'but')

Not if you wanted off the shelf _and_ wanted some headroom within the $$$/time budget.
IMneverHO

25% of possible total supply voltage range for the device seems quite flexible to me.
They have V to spare if their thermal budget has any room left.

I almost forgot.
"And the whopper, 1.5ms typical rise in output current from 10% to 90%."

It's too bad they couldn't place caps around the ASIC to compensate.
Oh wait.....

Are you some kind of inductorologist with mad skillz?
I didn't notice your suggestion for a better choice.
Please include delivery time and cost savings if you do venture an opinion.

To me their DC/DC supply fits exactly their 'margin on top of margin' claim.
Thx for the link!

Time will tell

Coincidentally, I am designing a 3 phase DC/DC power circuit that currently delivers 0.84V @80A w/ ~92% efficiency based around the LTC-3829, tunable @5mV increments, powered by a 12V ATX supply (+-10 nominal).  Each phases lower FET dissipates a maximum of 0.75W, which is the highest of any single component in the design.   I've got roughly 20 hours into the design.  Further, synching does not eliminate ripple.   In ideal situtations yes, however that's why any spice simulator worth using allows sweeps of tolerance ranges.  The reality is that the load is not uniform across the phases.  I'm not even going to address the rise time and caps comment as its obvious you have little experience with this type of circuitry.

The reason I mention the inefficiencies of their supply choice are that the poor choice of external PSU was due to "lower heat" then a week later post that they are dumping an extra 100W of heat into the chassis, which about what a good PSU would do (80% vs 90+% designs that are readily available).  All it takes is looking at any motherboard, gpu, or other high amperage, low volt device and making a few emails.

I just called KNC from USA and no answer....lunch time.....called again couple minutes later and got an answer....althought not what I wanted to hear...arrggghhhh

BUT on the other hand, they didn't try to get at my money like a potential scam most likely would have....so all in all postive.

hh, what you want to hear?.)

BUT on the other hand, they didn't try to get at my money like a potential scam most likely would have....so all in all postive.

Answers? Only 15 bucks upfront!

To answer you both.....

I ordered the  Saturn (paid in full many many days ago so I should be day 3 if there is such a thing) and as I tried to upgrade to Jupiter, my credit card payment would NOT go through, so I placed the order but did not fulfill the purchase.

As I was able to figure out my credit card problem I called KNC to see if I could still complete the transaction ( or in other words pay for the upgrade.)

The answer I did not want to hear was 'NO, you can't pay for upgrade anymore.'

The answer I DID WANT was 'Yes, we will gladly take your money for the Upgrade.' WHICH is exactly what a scammer would have said if this is a scam.

So minerpumpkin it is a hell of alot more than $15 for the Saturn and the upgrade.

The guy who answered said that they will be selling upgrades for us to install once they start shipping but no price or timeline given, nor did I ask.

Call for yourselves and ask away....

What is going to happen, people like Intel and Samsung coming in and crushing all the small time players? 

No.  Of all the risks this isn't one.  Total annual bitcoin revenue is a rounding error for a company like Samsung or Intel.  In theory (and I am not saying it is likely) some years or decades from now when Bitcoin is many magnitudes larger it might attract the interest of a major semiconductor company however by then the Bitcoin ASIC companies who have survived will have years of experience.  A big player would simply buy the company outright to hit the ground running.

Not sure what the relevance of a part made by lineage?  Didn't KNC state the power supply used in from GE Critical Power?

Is http://mining.thegenesisblock.com/ the best calc to use at this point?  I see a bunch of them out there and this seems to be the only one that is either very accurate or is the least favorable.

Not possible imo, but if price gets at 1000 before Christmas not sure they will be still not interested!

Wow! That is quite bad! Been a while since I did the calculation. And it assumes mtgox exchange rate.  

I sure hope they come significantly above specs and before the end of September.
