Having extreme belief in a religion does not make them stupid. You should not underestimate your enemy. Anyone use Cash, anyone use BTC. Not that it matters anyways.

Money is like food, or a car, it does not matter who use it. People should do better things with their time than point fingers at silly things.

You should mine outside China's pools anyways. Better payout and the Chinese has plenty of hashrate already.
Check out Kano, or Slush pool if you need steady payouts i'd say.

I'm way disappointed in Cryptsy too. Withdraws always has been slow, sometime 1-2 days (wtf?! for small amounts too). And they keep spamming me to go to Crypsty.ca to trade FIAT/BTC but its dead, no volume. Not sure why they arent integrating CAD with USD.

Is it so hard? Coinbase is doing just fine that way.

I am in Canada, so no.

I am not sure what people in US would be ready to pay for shipping, i'm guessing they would rather buy from people in the US for a single unit. For a batch, it could be doable if the price is right.

Ebay tend to be way more expensive, i recommend, again to check around here, you may get much better deal. Ebay tend to be 50-200% above forum prices. Just be sure to use the trustable escrow services.

In this case you,re only going to need 13~ S4, equal amount of ethernet cable, a router and a switch or two with 10 ports~, surge protector power bars for every outlet.

One air entry, one air exit, one or two fan to move the air.

I suggest you post an ad in the computer hardware market place and see what kind of offers you can get.

The battery only has USB output? Because i don't know if a single port can handle all that load. If you had a battery that can output all its power through a single connector(if it can through the usb port then good), then power the hub and the Pi, then plug the hub in the Pi, then 2x 5.1 2v output could give you 16 watts to play with?

Just not sure what you would do with a 5.1a 2v output.

Oh, i see now. Sorry, i don't know how to do this. If you used a Y splitter, plug one into the controller and one into the solar hub, i think you might be crossing current which i believe to be very bad, because they would not be feeding exactly the same voltage. If that was not an issue, this would work.

A USB port only feed max 300mA and 500mA i believe, so i don't see how you could feed a usb hub from a usb port in the first place. Maybe there is a hardware hack possible to feed the current from the solar panel to a battery, then the battery feed the current needed to the Hub, with either a hack or using a barrel adapter.

You're going to need specialized advice here, maybe RichBC or someone else with good expertise like Sidehack will read and comment.

I am not sure i understand, is there simply a problem with using powered USB hub ran by a AC-DC PSU?

From there you can use a USB Y splitter if you mean to get more power from the Hub to the stick. Especially useful to get more hashrate from the yummy Gekko Sidehack stick.

You simply flash your favored image strait into a SD. I use Win32 Disk Imager. Whatever was on the key before will get overwritten. Its the same for AntMiner SD cards or any image or OS image in general.

I don't mean to "push you off base", you'll just notice, especially for non high quality OEM psu, you will get little interest and very low offers. As far as used hardware go, its often 50% off retail price just for the fact its second hand. (And you typically lose fully or partially the warranty.)

Most educated buyer will probably stick to EVGA, Seasonic PSU or Superflower, Seasonic, etc as OEM. Thermaltake are typically in the "usually decent" category.

TLDR they are expensive, average PSU, not horrible but not particularly good either. The biggest problem with this one is its being sold at the same price as premium, top notch PSU.

It should probably be 170$ brand new. As a buyer myself, for a used one i'd put up 50-60$, if i badly needed a cheap PSU. But i would probably not use it much or for long, since i like to keep my miners running on cleanest power.

The cost here is lower and it account to about 20% of the BTC return. Also the efficiency @OC 393.75hz is the same, actually marginally better because you dont spin the fan any faster thus (1300-1155)0.8 = 116gh of income gained after paying for electricity. Great bonus.

Also China farm are also cheaper. So that would make it the majority and the price everyone need to compete at. The majority of farms either have cheaper than 0.5-0.07 or make their money out of ripping off people with crazy expensive hosting.

Regardless of your electricity cost you should run a S5 at 1.29TH/s because it does not change the efficiency. As long as its profitable to any extent, overclocking will make it better.

You can also feed downvolted current the S5 a little bit, or the v1.91 ones by a lot. When efficiency become critical or if you're somewhere you pay exorbitant electricity costs such as 0.1 to 0.15.

Just to be clear, here. You're asking 150USD per PSU and not for the lot?

The PSU has a Poor OEM so 150$ sound only a little low for all of them, while 150$ per is way too high (can get EVGA for 100$ which are superb).

I just honestly can't imagine somewhere with such dirty air. Even here in Québec we have relatively okay air and the dust does not accumulate overnight at all. It takes a year to have an accumulation that raise the temps by 7C~ for GPU and 2-3C for antminers.

And once a year, blowing compressed air through the heatsink is not really much maintenance imo, takes a few seconds per miner, which i only need to do at summer anyways because its cold 8 months a year here and then heat mean absolutely nothing, dust or not at this point.

If you live in a very dusty environment you'll need filters and lots of them i guess.

Anyhow. 17kW is not too bad on 240v. If its 120v that would be 141AMP~ which indeed sound too much for a "room". You'd need an industrial grade power circuit. Especially if you want to add some A/C during hot season.

Multiple of threads of his are like that. Posted, then locked, as if this was an ad board. Its not really so it feel like he is trying to silence the flow of information. I don't know if its a scam, but its definitively not someone i'd be interested in dealing with and i advise anyone with doubts to simply stand clear.

Scam or not, the method is distasteful.

No need for computer for running the S3 per se, the S3 is self sufficient, its controller is included, you just type its IP in your web browser on a networked computer to connect to its open-wrt software and input the settings you want. Then the mining will happen by the miner's controller.

Miners don't "work together", they all individually point to a pool and the work is pooled there.

It is not a USB device, so no, nothing of the sort.

You will need PSU's for 50 S3, so quite a lot of them. Ethernet switch, you will need 50 ports, unless you try to setup wifi on them. And 50 ethernet cable. A router to plug all the switches in. A couple of 10-12 port switches would probably be cheaper than one big one.

And earplugs.

A very powerful one, and i don't know exactly depend how much space you got to let the air through. And yes, there will be dust, so what ? Use compressed air from time to time and buy box fan filters on ebay or such.

Dust don't really do much unless you let it accumulate by the inch. Unless you live in a very dirty environment or next to a volcano, you should be fine. Here i just blow some air through the heat sink every few months for good measure.

If they are really dead then i guess thats too bad. At least you can get something back for dead S5 boards. Just wondering if those are actually dead. Let me know if you need to know what to do with your dead boards.

So for a few days, i was able to run them about half the time. Meaning they would usually crash when i go to bed and not being there to restart the whole thing, they would be down for the night.

However this morning, they suddenly stop actually hashing. They show hashing, but on poolside, they are not. I later noticed whenever the runtime on the controller would reach 1 minute, the controller restart.

So not only does a whole 4 board miner goes down half the time, and the other half of the time its just not mining. Now when i get it hashing, it actually get don't get valid hashrate.

Thoughts?

I tried different controller, same thing, different miner, same thing, different psu, same thing, different pool, same thing. So unless all 3 PSU decided they don't want to run these anymore and went on a strike, i don't get wtf. They still run 2x S5 each just fine so i doubt its the PSU, but i spent all day on it and i can't figure out what the problem is.

You would need several big 240v 15-20A A/C to cool all of that, its not a good idea, just push the air strait outside. I hope thats in a warehouse because that would be a lot of noise.
