Seems odd I've always just used pool-x, no downtime and all my shares paid...

Plus the local pickup recommended, and the fact he's selling it as broken. I doubt a scammer would do that. Hmmm interesting, don't these things have a warranty or is it just "If it goes wrong, your problem"
243  Bitcoin / Hardware / Re: Cryonics Frosbit claiming 1000Gh/s - $15K?? on: May 24, 2013, 11:43:33 AM
Their Facebook page claims they've already reached 40% of their pre-order quota, and delivery is on the 15th July (little under two months). So more BS, or there are some very foolish people that read Tech Crunch!

They have no prototype, just rendered drawings.

https://www.facebook.com/Cryoniks

Techcrunch is pretty sad, maybe they got paid off.

Heh facebook page, 17 likes but they've got 40% of a pre-order batch for $15,000 units, right. Some more technical gold from these fellows:

"You're very welcome! We find that the average North-American home is already pre-equipped to handle the power requirements of our units. For reference, we find that the average clothes-iron consumes roughly 1200-1400W when heating. A standard U.S 3-pronged outlet is sufficient to handle the working loads typical of our units. Hope that helps!"

Ok, so most North American homes have multiple outlets running off a single 15-20A 120V breaker. 20A*120V = 2400W, so an entire dedicated 20A circuit isn't enough for a single one of these miners, but they've somehow managed to find the "average" home is equipped to handle it somehow? I suppose if maybe you ripped out your oven, and wired up a hookup for this miner, but that might be something to inform potential customers about.
Great scientific research, references a clothes-iron as backup.

The machine doesn't exist so it's all irrelevant, they just don't want people to be put off ordering by the big energy draw.

Probably cheaper to buy new ones. Can someone find a good replacement on eBay?

Depends what the original CFM of the old fans was. I quite like the Arctic Cooling F range. F8 is 8cm, F12 is 12cm etc. They don't push loads of air though. Scythe make some of the highest performance pc fans but they can be very noisy.
245  Bitcoin / Mining / Re: Anyone know if I can switch my rigs PSUs over to 220V? on: May 23, 2013, 10:29:48 PM
it is STill the same number of watts, it is not magic you do not get anything for free......
Mmmm not quite. Most PSUs will run More efficient on a 220V line.

It's still the same wattage being drawn by the cards, that much is true. But, at the same wattage and higher voltage, the amps go down, which means less heat (heat = wasted energy). This lowers are draw from the wall, and can lower your bill. Only by 1-2%, but still...

EDIT: fixed a crucial mistake, and fixed a typo.

I was not aware of this. The lower heat would also mean less cooling required and longer part life though, wouldn't it? If so, I think that benefit alone would be worth it. Unless it's only a small amount of heat that is reduced.

I think the only parts getting reduced amperage would be the wire from the wall and the primary coil of the transformer, not gonna make a huge difference as those ain't things that are likely to go bad, the solid state components give out wayyyy before the transformers!
246  Bitcoin / Hardware / Re: Official CedarTec Topic - New ASIC [Scam?] on: May 23, 2013, 01:17:14 PM
So how is it that people in the altcoin forum who scam people for a couple of litecoins get a scammer tag quite rapidly.

Whereas a group that have set up an entire website, fake hardware and company continue to be allowed to have an account, thread and non-scammer tag. Yeah it's kinda obvious but the title still says "Scam?" when it should blatantly read "SCAM!!!!"

they have allot of money to throw at their scam, its a non-profit venture

You're back again? Whatever mr shill.
247  Bitcoin / Mining / Re: so my electric bill came in on: May 23, 2013, 12:29:36 PM
You might get a front door to the face if you tried that and weren't quick enough. Plus they could seize anything in the house for 'inspection' if they wanted, I know people who've had PC's/mobiles taken for months as 'evidence'
248  Bitcoin / Hardware / Re: Eyes to the horizon: A bitcoin ASIC project will be announced in June on: May 23, 2013, 12:01:59 PM
Seeing the pricing you propose for 1TH in model B (1,000-1,200BTC/TH/year), I'm afraid your IPO price will be too expensive. I would take into account that Bitfountain's IPO price was 0.1BTC per share, for an expected deployment of +250TH. If I do not recall it wrong, each share is 1/400,000 of the total profit/hashrate, which means that their price for TH was 160BTC, not a hefty 1,000-1,200BTC price tag.

Even at today's difficulty, a TH would take about a year to earn 1200BTC. Ridiculously overpriced, especially as that price only leases you the hash rate for a year.

At today's difficulty, 1 TH/s will make 1200 BTC in 27 days. (without electricity costs). You know, 1200 BTC per 1 TH/s is 1.2 BTC per 1 GH/s. Similar price as Avalon #3


True but with that you actually own hardware that can be resold etc, with this you just wait to hopefully get paid more than you put in.

Just a thought; DRM can always go wrong, and often does, generally punishing the paying customers whereas pirates and leeches quickly find a way around it. May not be the best idea.
250  Bitcoin / Mining / Re: so my electric bill came in on: May 23, 2013, 11:10:54 AM
this cop busting/raid thing is getting me a bit worried...

Sad


 Invite them round then? How many kw are you pulling from the wall? Anything above 1-2kw constant is gonna look odd to the power company, and some are obliged to tell the police if something looks dodgy.


Just invite them round for a cuppa, explain your concerns and show them your 'servers'.

You trying to melt your laptop? Many 'M' gpus run up to 90 odd degrees when just gaming! Oh yeah the 9700pro was great, remember playing BF2 on a vmodded one!
252  Bitcoin / Hardware / Re: Eyes to the horizon: A bitcoin ASIC project will be announced in June on: May 22, 2013, 09:13:06 PM
I think everyone is using the same chips from the same supplier in China.  They all appear to have like performance and the same 130nm architecture.  That can't be coincidence.  100t is a lot of boards and a LOT of power to get up and running.



Nope if you paid attention they are 64 pad chips at 400mhz that they seem to be designing themselves looking at the pics posted.

In a lqfp no less, ie something like this.


At last a seemingly properly professional development without daft amounts of pre-hype.
253  Bitcoin / Hardware / Re: Klondike - 16 chip ASIC Open Source Board - Preliminary on: May 22, 2013, 04:03:34 PM
As for myself I'm more of a hardware kind of guy. I intend to design and solder some nice boards for hobby purposes  Grin , no intention of selling it though. If the avalon guys release the VHDL source for the FPGA I'll go that route, if not I'll be forced to use a microcontroller like Klondike (and burnin) uses. So I'll be watching this thread. 

I ordered a few extra chips to make some dead bug miners.  No doubt I'll struggle with the 1.2V etc but I've wasted $8 on worse things.

I wouldn't worry too much about the software, there will be a bit of time between sample and production, should be enough to iron out the protocol.  Anything that doesn't need a board re-roll is ok.

Dead bug idea is great why hadn't I thought of that! Should make heatsinking pretty interesting too! I'm imagining a watercooling system made from bent copper pipe with ASIC and voltage regulators attached at random intervals using some thermal adhesive. Would look really cool.

Found a 2a 1.22v switching regulator that takes 5.5 to 36v and is only $3.80 in singles, perfect for this kinda thing.

254  Bitcoin / Hardware / Re: RaspberryPi made ASIC board for Avalon chips anybody? on: May 22, 2013, 03:12:24 PM
When I saw the list of avalon boards, I thought why not have it made by the pi-makers?



you mean Sony? lol

yeah keep wishing


How on earth have you confused Sony and the Raspberry Pi Foundation

255  Bitcoin / Hardware / Re: [Guide] Comprehensive ASICMiner Blade Setup on: May 22, 2013, 02:33:16 PM
I just know I wouldn't trust more than 5 amps down a single PSU wire, better safe than sorry! And at the moment it won't really be drawing any power due to sitting at idle; ie the chips aren't at their TDP and neither is the power draw, just strip another cable coming out of the PSU and add that to the other input. I really don't see the need for more grounds than positives two of each should be fine, maybe three if you want to overclock. And get some Arctic F12s they're only a few quid.

As for what he's done, yeah it is odd to do it like that. Although the smaller the run of low gauge wire the less problems there should be.
256  Bitcoin / Hardware / Re: [Guide] Comprehensive ASICMiner Blade Setup on: May 22, 2013, 11:47:30 AM
Those wires could melt or burst into flames, they have almost 10 amps going down them! This may also be the cause of the random restarts, either that or overheating; running without a fan is just asking to burn out your chips.

Stop being daft and read the bloody setup guide! Unless you want to kill your new 50BTC worth of hardware before you can even mine.


What would be better, getting it improperly setup today and running for a few hours till it dies. Or actually researching and setting up properly and getting years of use out of it.
257  Alternate cryptocurrencies / Altcoin Discussion / Re: I need help. on: May 21, 2013, 12:30:13 AM
Probably need to use a different port?

My port is already pretty high... it is 10263. Do any other coins use that?

Your coin is trying to tell you that you've copied too much code. Do something original and it will work fine.

This is funny, do you think plain out copying the YAC FUD will work?
260  Bitcoin / Mining / Re: Anyone know if I can switch my rigs PSUs over to 220V? on: May 20, 2013, 11:42:28 PM
He said that some of the power supplies they use up there will take 110 or 220 also but that once you hook it up it always wants whatever it was hooked up to first.

So he thinks they'd put a sensor and a circuit to remember that and burn it to memory forever, rather than just a sensor.

Think twice about allowing him to rewire your home.
