Okay but how can you go through an airport scanner with this thing in your pocket during your holiday vacation is the big question Cool

Yep I was wondering the same thing. Tough to stop those guys from going through your stuff, and snapping a picture of the code to rob you when they get home.

Seems pretty cool. But it shouldn't be so small or expensive and they should use gold instead of steel.

And there should be a silver and platinum option as well.

May group bay 112 kwp panel

1 kw solar panel 110 euro + MWST with transport to Croatia
next week delivery

Might be able to get broken/defective/shattered panels without any warranty or guarantees for that price. But my local salvage company pays more for broken solar panels than that, so I doubt anyone in the US would ship panels to you at that price.
You might be able to obtain individual solar cells and put them together yourself, for close to that price? Might be a fun project, lot of work though, stringing the cells and encasing them properly. I stopped doing that when the price dropped below $4/watt. The large scale manufacturers just make the finished product so much better than a hobbyist can achieve. There is a lot of details that go into a finished solar panel, even the glass is manufactured with special anti reflective glazing.
USA is exspensive. market for solar this panel is not broken/defective/shattered panels this is panel year production 2010 .bankruptcy company.used in 8 solar field in germany. and i totally bay-paid and sold 168 kw
and have group reservation for another 168 kw but,no more panels.
in 2 days i easy sold 168 kw http://www.e-vozila.com/forum/viewtopic.php?t=5562

 warranty or guarantees is for pussy. who don't risk don't make profit.

If the panels are working to specification, it sounds like an amazing deal. Why did the solar fields go bankrupt? At that price offering I'm amazed no one stepped in to buy the facility and keep it running. There must be a reason.

Power storage. You need batteries and potentially solar tracking to make such a system a truly 24 hour solution for powering miners or homes unless it is on grid or grid tie solution.

LiFePo4 is likely a great solution but the costs of battery storage at the outset of a project is difficult and very costly.

MPPT's are not cost effective?

It's a good video but It's a bit apples and oranges. It only applies to a purely DC to DC off grid environment, and he clarifies that in his video as well.

As for the field in Germany, I seriously doubt it was a power storage issue that caused the bankruptcy, they have some of the best net metering rules on the planet.

I would be down to get a few panels if the price was at wholesale discount.  Wink

Just let me know how many watts you want and where you want them sent.

Sometimes it doesn't reset on the first attempt. With the power on, hold the reset button for 5 or 10 seconds then release, then turn the power off for 5 seconds then turn it back on. If that doesn't work, then with the power cord unplugged hold the reset button and plug it in while holding the reset button, then release the button, wait a minute then unplug it and plug it back in.

^The SP20 is about 2x longer than it is wide or tall, and works well. the back chips run a little warmer but are still at an acceptable temperature

It works well compared to other commercially available miners, but it's still a crappy design that most people aren't able to run at it's rated output because it gets to hot. The vast majority of people are underclocking their miners because of poor heat dissipation, energy consumption and noise.  The previous poster just explained in simple terms why that is and how to fix it.

Really looking forward to all of the nuclear and coal plants being shut down.

I fully agree with the coal plants being shut down.  But why nuclear?  We can now build nuclear plants that generate no waste and do not melt down.  That makes them clean and safe.  Also material from old nuke weapons are being used in nuclear reactors.  What an excellent way of getting rid of these dangerous weapons.
we can build nuclear plants that generate no waste ? ! O_o
what the fk have i missed please link me to an article or smth

os2sam apparently drank the Koolaid (jim jones brand, not to be confused with the stuff john lennon was drinking when he wrote imagine) and is just regurgitating the propaganda that he was told.
US just dropped 50billion on 2 nuclear plants that will probably never produce any energy(too dangerous to run, every nuclear plant should have been shut down years ago), for the same money we could put up twice as much solar power and have it all running in less than a year.

The price of the chips costing so much has to do with volume.
I'm sure to buy 100 is expensive as a full miner giver or take. The companies making the miners
has no incentive to sell hardware that can mine more than they sell for.
Once the machine is ran for a while, sell it get a new one and repeat. Sell the crumbs to the peasents.
Name one mining manufacturer who isn't actually mining with their own hardware?
Yea we're nothing but capital to them.
Plus the more hardware you sell, the higher the diff goes up and it makes it harder on everyone to make a buck.
The labor in china in assembling a miner can't be more than the cost of one chip.
I'm sure labor overhead is the least of their concerns in China.

Spring festival ends soon. Maybe they come back from the festival with some good news for us.

Yep you and the other thousand orders that bitmain is not interested in. Maybe they'll release an upgrade kit to the S7.

What are you thinking about getting a tesla and camping out at one of their free for life rapid charge stations? I wonder what their terms of service agreement has to say about something like that? 40kwh constant at 10cents/kwh would be worth about ~$35k a year. With tesla's 1.7% finance plan, they would be paying you about ~$25k/yr to sit at their charging station 24/7. (this analysis assumes that you're able to mine 10cents/kwh x 40kwh 24/7 of btc + the cost of equipment + any efficiency losses).   

Really looking forward to all of the nuclear and coal plants being shut down. Just think... it was only a decade or 2 ago that coal represented nearly 60% of the US energy supply.  Clean safe energy technologies are definitely on the rise. Shame the US just wasted over $50billion on 2 nuclear plants that will never pay for themselves.

If you'd like I can get you very inexpensive solar panels delivered to your house in Georgia that are fully compliant with all US rules and regulations for grid interconnection complete with a 20 year manufacturers warranty for under $1 a watt. I also accept bitcoin for solar panels. One of the oldest solar pv companies on the east coast http://www.ecologicalsystems.biz/ would be the ones providing the solar panels. Their credentials are impeccable so you don't need to worry about any scams with them.

    I know buysolar he is on my trust list because I know him and helped him setup a sp20e , some s-3's.
  He runs a solar company and is legit. He knows the  ins and outs of his state laws and federal laws as applied to solar energy.

Hey buysolar what's up?

Thank you for the kind words. I'm just enjoying the snow from the comfort of my miner heated solar powered home. I liked the poll you ran philipma1957, sorry it got cut short.
Yes I designed and installed the first privately owned wind and solar powered electric generators that were allowed to be tied into the public utility grid in my state, which last time I checked was the 2nd largest solar market in the US. I've also done a bunch of other energy utilization projects over the years. 
If anyone is really interested in setting up an off grid or on grid mining system utilizing the most cost effective energy processes currently available, I'd be happy to consult. But what I'd really love to coordinate is an energy deployment maximization plan for one of these larger scale deployment facilities, they are dropping the ball on duel purposing their facilities. Bitfury, Friedcat, Bitmaintech, Spondoolies, KnC... they've made great products, but they are showing their lack of depth on their larger scale mining deployments. It's only a matter of time before an entity steps into the fray with a more comprehensive methodology. All of these entities which are deploying miner facilities that live and die based on the cost of energy and the price of bitcoin at any given moment just haven't figured it out yet. I'd love to help them unhinge from the temporal whims of the bitcoin market space in a way that enables them to enhance the services they are providing to the general community and increases their competitive edge. If large scale deployments truly want to maximize the value of their participation in the bitcoin mining market space.... they will need a more comprehensive philosophy.

That's a really good price!

But let's compare it to hosting. You say about $1000 for 1kw system. Georgia gets about 1700 kwh per year, but you'll lost some efficiency for battery, etc., so let's say 1500 kwh, or roughly 2 months of power. You could host the miners at a bitcoin hosting facility for $180 for 2 months, much less if you agree to longer terms.

You need to run the miners for more than 5.5 years without downtime to break even compared to a hosting facility. Good luck with that.

You make some great points. But there are other benefits to consider too. There's a 30% federal tax credit in the US for solar panels as well as a super accelerated depreciation table, if he's able to use these incentives it will improve his ROI substantially. Also the panels and the electricity they produce can always be used for other purposes besides mining.  

edit: I also forgot to mention, that once your solar panels have paid for themselves, your energy costs drop to 0, at which point cost per kilowatt hour becomes irrelevant, and your only remaining consideration is the earnings per kilowatt hour produced.

Shows us the spreadsheet for a typical small farm so we can actually see the numbers.

I think you would be hard pressed given current and or future BTC prices to make a reasonable solar only mining operation viable. But show us the numbers to contrary.

Where is this farm going?
There are a lot of variables in the question you're asking. The answer is going to vary by a substantial amount from state to state and country to country.  For instance in my area, if you connect to the public grid, you get the electricity from the solar worth ~$0.17kwh + an additional incentive for clean energy of ~$0.10 to ~$0.2kwh + federal tax credits and depreciation which pay for ~50% of the total system price. So people in my state will typically get between 12% and 30% ROI annually depending on the exact components used and the buyers ability to use the federal incentives. My state also has some of the strictest energy standards on the planet, as well as a number of additional bureaucracies to deal with, So the up front cost of a solar system in my state is substantially higher than in other places.

Put me on the list for an 8 board complete water cooled kit when the price drops below $1200. 
Sorry to say that we couldn't provide water-cooled S5,and we only sell modify kits now.Price of air-cooled S5 may drop below $1200 or even lower cause value of bitcoin changes all the time,but will you buy it at a low price while bitcoin value is very low,too?

You make a great point. I agree, it depends on how far into the future you are talking about and a bunch of other variables too. If bitcoin is ~ $200 next week and you offered me the 8 board complete kit for $1200 at that time, I would definitely buy the kit. But if bitcoin is $600 in 4 weeks and you offered me the kit for $1200 at that time, I wouldn't want it.

Huh?  Your logic is all backward.  Why would you jump at buying a miner for 6 BTC and turn it down for 2 BTC?

Because at that price everybody and their mother would want to mine and difficulty would go through the roof before any chance to ROI.

78  Bitcoin / Hardware / Re: Modify S5 Antminer to watercooling on: January 30, 2015, 05:46:58 AM
For some yes, but for most ppl it is not worth Embarrassed

Atm i'm looking for an electric boiler with coil for steam&hot water. This way i will not trow away the heat and have warm water(~40c) at the sink but also washing machines!

Yes I'm also planning on using the liquid cooled miners to heat the water in my hot water tank. One of these 8 board S5's running at 2400watts should be more than enough for the average family. I even installed a heat sink for dumping the excess heat when the hot water tank hits the right temperature. Once I dig in the pool, I'll be able to use them to heat the pool as well. Right now it's 9 degrees fahrenheit outside and my whole house is being heated to a very comfortable 72 degrees fahrenheit by air cooled miners in the basement radiating heat through the floors. By using the heat from the miners we get to radically extend their usable life cycle. Once I've completed my solar pv system my site will be 100% self sufficient, the only reason for me to swap out miners is due to hardware failure or to increase mining density per unit of energy consumed. This is why mega farm commercial operations have trouble competing with small home mining operations. However I do have quite a few wonderful dual purposing solutions for them that would substantially increase their profitability.

https://bitcointalk.org/index.php?topic=936343.40

Hi,

Some good news for you, we have received a bulk order from one user for 9 units.

If you would like to place an order taking the total to 10 units we could offer a "group buy" discount taking the total price down to $1086.

BTC price is : 4.68BTC

Should you wish to proceed the BTC address for your order is : 1MKvKRKR44R5nieRfEzNpggNCJtqb3K6so

After funds are transfered please drop me a pm with the transaction I.D and your details.

Kind Regards,

syscooling


Its very nice of you to post here to alarm others.Only I take responsibility for this forum,and if we have group-buying activities I will post a thread and will never send you PMs.

Just trying to help. Hopefully, this guy doesn't trick anyone into giving him coins. He's obviously well practiced at conning people out of their money, the story he gave seemed very plausible. If I wasn't so paranoid (and have a strict set protocols that I use before sending anyone any money), I would have fallen for his con.
