Does anybody have the commands for installing nano on the s3 by putty?
Tried "opkg update" and "opkg install nano" but get errores on the first already

The repository in /etc/opkg.conf is incorrect, so it doesn't have any packages to install.  However even if you fix that (add /base to the path), there isn't a precompiled nano package for this openwrt variant. I suggest learning some basic vi skills, as it's the lowest common denominator in the editor world (any *nix machine will have vi).

Pathes have changed on openwrt repository server, there are now 5 different pathes. You have to change /etc/opk.conf:

Code:

root@antMinerS3:~# cat /etc/opkg.conf
src/gz barrier_breaker http://downloads.openwrt.org/snapshots/trunk/ar71xx/packages/packages
src/gz base http://downloads.openwrt.org/snapshots/trunk/ar71xx/packages/base
src/gz luci http://downloads.openwrt.org/snapshots/trunk/ar71xx/packages/luci
src/gz routing http://downloads.openwrt.org/snapshots/trunk/ar71xx/packages/routing
src/gz management http://downloads.openwrt.org/snapshots/trunk/ar71xx/packages/management
src/gz telephony http://downloads.openwrt.org/snapshots/trunk/ar71xx/packages/telephony
dest root /
dest ram /tmp
lists_dir ext /var/opkg-lists
option overlay_root /overlay

Code:

opkg update && opkg install nano

should work after modification. You could do the changes also via webinterface of your Antminer.

It should be good enough for 500w, enough for an S3 but you may need to add a 5v load to get full efficiency. A 4r7 ohm 10w resistor across the 5v lines may well solve your problems

This is not necessary.  A simple jumper/bridge (paperclip or whatever) will do just fine.

the new EVGA B2 750+ supplies come with a jumper header for using the power supply not in cases!
They have accepted their power supplies are being used for MINING!

Hi,
We would honor the promise of earlier shipping than Sept. 20th 

Great news!

What are recommended PSUs for Antminer S3 to buy - in Europe/US?

I don't know much about PSUs, so a link to a PSU 101 article (at least as it relates to bitcoin mining) would be welcome as well.

I read:
http://www.reddit.com/r/BitcoinMining/comments/24intr/best_corsair_psu_for_my_antminer_s1/ch7mntp

"Efficiency ratings describe the amount of electricity that the PSU loses as heat while powering the unit. Because miners are always on and consume a lot of power, more efficient units generally recover their higher purchase cost in less than a year. In nearly 100% of cases you'll save money by buying a platinum (or gold) rated PSU."

Sorry for quoting myself, but any help with this? From a total beginner level, like understanding power draw on the PSU. Thank you.

Something to remember, when you select a power supply(s) keep in mind that even if you select the best 80 Plus Platinum supply, you'll want to get one rated at about twice (optimum/peak efficiency of most power supplies is around 50-60% of rated power) of what you'll be pulling through it.  So if you have 2 S3's and they're overclocked and pulling 374w each, then that's about 750w, so you should be looking for something in the range of 1200-1500w in platinum or gold rated. (also keep in mind that some power supplies have multiple +12v rails that usually max. out at 30A each, which might not be enough for a overclocked S3, so a single +12v rail might be a better choice)
Also, if you want optimum efficiency, use a 240v source if available (some houses have a 220-240v line for washing/dryer, be sure to switch the selector on the power supply to the correct voltage before you plug it in) which should add about 2% addition efficiency.

Perhaps a better suggestion would be to look at the efficiency curve of the PSU since although your assertion about effeciency at 50% load is accurate the difference doesn't necessarily result in savings that offset needing to size up to a 1200-1500 when a 750-1000W will do.. For example for 80 Plus Platinum at 50% load it is a minimum of 92% while at 100% load it is 89%, and PSUs will move around above that bottom threshold.

Anyone else made a deposit to hashnest.com recently and not received the deposit in account?

All my TX id is same as the previous one that worked, this one however never ended up hitting my account.

Is this a unique issue or happening to others? I have a support ticket in now. Hopefully it is resolved soon.

  not sure same as bitmain site that I ordered one L1 and paid by btc and in account still not say pay yet for one hour now.
I did them for it.

Can i have some bitcoin too?  I mean, considering youre just pissing it away, Id figured id ask.

[jpchrist]

If anyone is interested im selling 2 antminer S3s for 0.65 BTC each with free shipping anywhere in the US.  I can ship same day is payment is made early.  They are from batch 5. BOth units can be successfully overclocked to 237.5 and 1 can be overclocked to 250. Figure I'd see if anyone here wants them before I throw them up on ebay.  Send a PM if interested.

You might wanna try in the Bitcoin Forum > Economy > Marketplace > Goods > Computer hardware if you want to sell them. But remember on ebay buyer protection can hurt you bad. some buyer buys them hashes away for a month then opens a case and returns them full refund of shipping plus purchase price.

Sorry to say this but you have absolutely no idea what you're talking about.

There is some inefficiency to account for in most PSUs but certainly not close to 50% on current PSUs. Most PSUs will happily run 24/7 at 80% (or more) of their rated watts. Some good quality PSUs will run 100%+.

Poor example: Bitmain used cheap 1000w Gold Enermax PSUs in their S2s. And those miners use 1000w pretty consistently. Mine pooped-out after two or three weeks but many others are still using them many months later.

he means, this thread is "ANTMINER S3 Discussion and Support Thread"
and that guy's talking bout hashnest

  yes, for S3 but same owner.

I have a Corsair AX1200 high end power supply having min 90% efficiency at 50% load.
I loaded it with an overclocked S3 (s) running at 250Mhz and 500Ghs+.
The power consumption at Wall is around 400W at 220VAC.
I then connected it to a 12V DC Source directly omitting the Power Supply.
Now the power consumption is around 260Watts to 300Watts, the DC-DC converter's efficiency is near 90%.
So, I should assume from my findings that before PSU the S3 consumes <300Watts and at all 430W.
The ammeter used in both case where same and did testing multiple times with same results.
Antminer S3 <- 24VDC-12VDC Converter <- 24VDC Solar Charge Controller <-  <300W
Antminer S3 <- Power Supply                <- 24VDC Invertered to AC         <- 24VDC Solar Charge Controller <-    430W

What variant are they using with the S3?

@Askit2: Thanks.

Meanwhile I learned I should buy a Gold certified PSU. Agree?

Now the question: Antminer's Google Translator supported customer service says if I use 1 big PSU to power 2 miners, they will generate only 800Gh/s. Compare that to 453Gh/s per single miner.

Should I run 2 miners from 1 or 2 PSUs? How the math all adds up?

[Soros Shorts]

So if you have 2 S3's and they're overclocked and pulling 374w each, then that's about 750w, so you should be looking for something in the range of 1200-1500w in platinum or gold rated.

A lot of people from the various hardware overclockers forums like to keep saying this. While it is probably fairly accurate statement, under most circumstances for Bitcoin mining it does not make financial sense to go for that extra 2-3% additional efficiency when you end up having to pay $100-200 more for the larger PSU just so that you can run it at 50% load.
