How did u turn down the coolig fan from the dell 750 watt psu ? Im running few of those and they are a bit loud
Depends on the model but this may help
I'm using server PSU's. Dell 1570W one's. They power 3 ants... (2 oc'ed and 1 normal freq).... Can get them to work all 3 oc'ed... But it will take me some time... As the PSU has 5 Output pins which have a max of 312W per pin. I would need to connect the 5 pins in order to get the full 1570W out of it..without worrying that I will ruin my PSU. (Happened to some 930W one's I had...I wasn't aware that they had a max W on the output pins).

I didn't think to use Server PSU's. Yes, the price per watt is remarkably cheaper than your typical desktop PSU. Looking at pictures, I can't tell how you would be able to use this. Is there a breakout cable that attaches to the only port I can see?

On this forum you'll find loads of different PSU conversions.... Just one example of many:
http://www.rcgroups.com/forums/showthread.php?t=1750411

You'll need to jumper a few pins together... but it's really REALLY easy.
Then you can opt for another jumper (of 2 pins) and that will lower the fan speed.

The PSU I have....it sounds like a boeing 747 on the runway... so that jumper saves me a load of headache!
Installing a couple of 1k resistors will reduce fan speed depending on load.

see http://www.raptortechnique.com/12vpower.htm

I thought thiers was a little messy thou, so I made up some resistor banks that just plug on.

For extra fun, lets say

A block was mined from the US pool,
whilst I was visiting England,
and my pool was pointed to Mtgox in Japan,
but my miners where in Australia.

For tax purpose where did I receive my property, who do I pay the tax too ?
283  Bitcoin / Legal / Re: Bitcoin Is Property Not Currency on: March 27, 2014, 10:47:53 AM
Thanks bbeagle for your reply it is appreciated and probably correct. Am just throwing out thoughts.

Am not actually a US citizen but you can bet this will be exported to the rest of the Anglo-american empire real soon.

So just for fun.

Lets say others adopt this.

Am a UK citizen living in Australia.

I transferred money from a UK bank to MtGox Japan and purchased BTC.

I purchased Mining gear with the BTC in the US for delivery in AUS.

I used the gear to mine BTC on a US Pool and purchased more miners with that from China in BTC, Miners in Aus.

They mined coins on a US Pool, that I exchanged in Aus to my Aus bank Account.

My overall position is probably negative (loss) for the year.

Assuming each country adopts a similar policy, I have a bit of a headache.

284  Bitcoin / Legal / Re: Bitcoin Is Property Not Currency on: March 27, 2014, 10:16:14 AM
If you mined a coin at $1200 then you technically received property worth $1200 that is now worth $600.

When can you realize the loss?

This is hurting my head.

If your in a foreign country and using a US pool, are you liable for earning on property in the US?

Surely this is virtual property and a virtual problem.

If you use a off shore pool and exchange, then your property is outside US until you exchange that foreign currency for US dollars is it not ?

OK, you have overseas property gains by US terminology but in that country it may be a virtual property.
285  Bitcoin / Legal / Re: Bitcoin Is Property Not Currency on: March 27, 2014, 09:23:09 AM
 Cheesy Can you guys base those earnings on MtGox rates, $122 wasn't it when last traded.

Or do you have to base it on the price of an US Exchange  Wink

Now what if there was only one US Exchange and it was like a fraction of the real price (no buy orders obviously).

Are those coins Earned oversea's ? or in the clouds ?

So much to go wrong here.. Shocked
286  Alternate cryptocurrencies / Mining (Altcoins) / Re: new to mining on: March 27, 2014, 04:58:25 AM
So I have around 2000 USD$ and I want to create a fully functional mining rig I'm pretty sure if I have someone else build it it'll cost more so I'm going to buy parts but i'm really strict about the 2000$ limit I want to do a sha-256 algorithm

suggestions
A)buy a shitty laptop and buy a butterfly labs to connect so i'll save a few bucks
or
B)buy a case motherboard-graphic card-ram(which i have 2gb laying around somewhere)-cpu- and probably just make the 2k$ limit
or
C)is there a 3rd option?

if its option (B) could someone guide me in creating a rig?

A = research butterfly labs, do not buy from them, you may as well toss that money in the bin.

B = Not worth it for Bitcoin, speak to others about altcoins, some claim its still profitable I believe.

C = Just buy some Antminers from bitmain, it is debatable if they will break even now but they hold the best chance. you can get 3 x 180GH/s and still have some change.
287  Bitcoin / Bitcoin Discussion / Re: What if Bitcoin was a currency? on: March 27, 2014, 03:19:20 AM
Lets all pitch in and buy a sovereign Island, declare its official currency as bitcoin.

Setup our own exchange there and a data center to host pools.

Think of the press that would get  Cheesy

Just need to find an Island now  Huh

Edit : Forget the Island, Bitcoin to the Moon ^^

The nest will actually link to each other using the same wifi network I believe. I have another in the house by my bedroom. So with the phone alerts and link to that one I should be good. Im mostly worried about when I am out of the house.

If you already have nest in the house then yes, defiantly stick with them.

If your really paranoid ( no offense meant, I myself have turned mining gear off whilst away for a weekend) there are a few options.

If the nest has an auxiliary output you could switch a contactor with it ( if it activates your miners are shut down ) without electricity you will limit the damage.

If you really want some form of suppressant perhaps a large bottle of co2 ( ask in your local pub, they have bottles out the back Wink ) and a gas valve coupled with shutting off the electricity may do the trick.
290  Other / CPU/GPU Bitcoin mining hardware / Re: Building Antminer Shed. Any suggestions on design or air flow? on: March 27, 2014, 12:00:07 AM
Absolutely will Smiley


soo... Fire extinguisher, Nest Smoke Detector, remotely operated light switch and IP cmera to look and see inside if I get alerts. Should be good to go.

+100
I have little experience with the nest smokies so can't vouch for them (I have been installing smokies for over 10 years and no-one has ever asked for them) however am sure there good, all good quality mains smoke detectors have an option to interlink to each other with an extra wire ( so you can have one in the house that will activate at the same time) There are also some battery models that have a wireless radio link to each other. Like this http://www.sdfirealarms.co.uk/fire-protection/radio-wireless-fire-alarms/battery-only-radiolink-alarms/ei3105rf-radiolink-wireless-optical-9v-smoke-alarm.html, wired link is obviously better but not always practical.

Oh? Do share how!

No, please don't. Water and miners do not mix.

I recommended a couple of Brooks smoke detectors (wireless linked) one for shed the other in house.

You could mod this to shut off the supply or operate an Halon fire suppressant but sprinkler? I suggest not.  

Edit : small thought experiment

Metal Shed (or other with wet floor) + Electricity + Water + Mad nerd trying to save $$$ of miners on hearing Smoke detector

Shocking

It will not be metal. I twill be cement board which doesnt burn. It will also be pretty water tight- about as tight as you can get. I have another shed on the opposite side of my yard that was custom build that doesn't leak a tad. I think it will be alright.
No worries, my comments where more in respect of those suggesting putting in a wet sprinkler system not the shed itself. I would recommend a co2 extinguisher by the door though.

First official Beef for Bitcoins thread lol



Just Thought it worthy to note that for those in Aus there is http://www.honestbeef.com.au/index.php that excepts Bitcoin.

I have not tried them as I think am too far from them for shipping.

Packs are 20Kg so make sure you have plenty of freezer space.
293  Other / CPU/GPU Bitcoin mining hardware / Re: Advice building Antminer S1 Farm on: March 25, 2014, 12:11:50 PM
Can someone give me advice on design?  

1) What kind of line should I have my electrician run off my panel?
2) What PDU to get?
3) Which PSU and how many S1's per PSU and per 120v circuit?
4) What racking to get?

1) 240V, more amps the better, if you are going to go big discuss it with an electrician. Get him to put in a sub board and think of future capacity.

2) will ur internet work if your local exchange has no power? If not its a waste of money, but is probably not cost effective anyway.
sorry read pdu as ups  Grin do you need a psu (maybe this is a us term am not familiar with as i have read it a few times recently) will normal sockets not be enough? make sure they have an RCD and think of a sub board for protection.

3) If you are handy with a soldering iron and noice is not an issue I would go with modding server supplies, theirs a few threads about them here already, I would recommend 1 per Ant for redundncy as there really cheap anyhow.

4) Any that has enough depth + a bit, mine is a little short. Wire racking will allow better air flow but is conductive so take extra care.

Additional

If your having new line installed get the electrician to install an isolator near the door, its relatively cheap initially and will provide quick isolation should you have problems.

Put a CO2 extinguisher near the door.

Whats shocking is that you dont know what you're talking about.

Goodluck with your solution when you're not at home.

You best make sure that shed is bonded to earth and has an Residual Current Device on its supply  Wink

296  Bitcoin / Bitcoin Discussion / Re: How do we know if Satoshi is still alive? on: March 25, 2014, 05:26:20 AM
but I am sure, he is swimming in the pool full with money.
Actually, the one thing we know for sure is that she/they/he are NOT swimming in pools of money. It's all right there on the blockchain.

Not a single penny of this person(s) wealth has yet been touched!

This means one of two things:

1. They/she/he is waiting for their BTC to be worth FAR more than it currently is before they're willing to touch even a fraction of it. Meaning they anticipate enormous valuation increase within their lifetime.
2. Bitcoin was a gift to the world, and the creator will never touch any of the wealth. The implication being that it was - and always will be - an utterly selfless act.

Given just HOW MUCH wealth they have, scenario #1 seems exceedingly unlikely to me. If you have millions in BTC, what's the harm in cashing in a few thousand to buy yourself something nice?

Again, NOT ONE PENNY has been touched! Take from that what you will.

The conclusion I must draw, as a man of reason, is that the invention of Crypto was a selfless act - a gift to the world just like Newtonian physics (Isaac Newton was paid only in books for that revelation).


His true reason was world domination.

Once Bitcoin goes mainstream and is worth a $hit load he is gonna come out and buy ur and everyone else's a$$.

All Hail Satoshi, Emperor of the Earth

If your looking for subject matter I found this an interesting read earlier today from Techcrunch.
http://techcrunch.com/2014/03/22/enter-the-blockchain-how-bitcoin-can-turn-the-cloud-inside-out/

Just a snippet
Quote
You see, it’s not that hard to imagine other blockchain-based systems which aren’t currencies and don’t attract as many “colorful personalities.” Suppose you replaced the Internet’s centralized Domain Name System with a blockchain for Internet names (like Namecoin) such that every DNS request included some proof-of-work effort. Or you used any blockchain (including Bitcoin’s) as a notary service. Or you built a new blockchain for crowdfunding. Or you replaced a centralized system which absolutely does need to be scrapped — that horrific barrel of worms known as TLS/SSL Certificate Authorities — with a blockchain-based solution powered at the browser level.


300  Bitcoin / Mining / Re: Nearly burned down my home due to mining farm (tips on how to stay safe ) on: March 20, 2014, 07:40:12 AM
I still think it is a good idea to run your 110v/240v through a hold on contactor, connected to an axillary relay of a smoke detector.

Smoke detector activates - rig powers down.

Maybe I will look into making some kits up. Although its difficult as each persons situation is different.

May also be worth adding an Emergency Stop button at the door of the room to activate that contactor manually.

Edit : These could be done relatively simply with wireless battery smoke detectors ( from memory they cost around $100)
         and a wireless relay unit attached to a custom contactor box, with 3-4 10A input/outputs. So a basic system would be in the region of $300 - $400 + $100 for each additional detector ( placed anywhere in your home) sounds expensive but if your using detectors that cost less than $70 then you may as well not bother cus there cr$p.
These are of the top of my head figures for 240V version ( not aware of suitable products for 110V) if there is interest I will investigate further and make a demo unit with proper costs.

Edit 2 : Maybe a pain in the ass when the kids burn there toast and it shuts ur mining rig down, so dont bank on putting xtra detectors near the kitchen.
