(Somehow I don't think that a few Antminer U1/2's pose an interesting challenge to hackers.... Undecided)

Cheers

Hey I've got 2 more coming :=_)
BTW Here to learn not to make money ( YET }:> ) and that I'm doing Smiley
Thanks for new info and fell free to correct my noob theories when not to lazy Smiley

P.S. I'll try posting a bit less , but unless I don't ask answers are not given so bare with me plz

Mine was low to. But in my part my miners were redirected again right at the end of the round. So slushes antipool hopping code got me good. Is anyone elses bfgminer being redirected to the russian IP still. I was fine all week and got hit twice this weekend. My equipment is in a remote data room, running all BFL hardware. Good thing for API.
[/quote]

Things I wound helpful was checking that slush is the only pool in the pool list , deleting  bfgminer.conf and starting whole hing from BAT with SLush pool as only pool showing.
Seems to me that then work was done you will get bogus block from slush just to try and stop pool hooping.

What should happen is that once block is solved and no more new block are found all
your miners should start working on bogus block just to make sure you stay on slush
when it's dinner time Wink

There is always Murphy's low , my computer went out yesterday and I only started mining this morning (there was an blackout with all the power in the house) so go
figure Tongue

When you want to use another pool do the same thing , single BAT that will show
your pool of choice as only pool (not active) buy only pool showing , when you want to go back to slush just use different bat and report results.

It's not that well done in BFGMiner I must say and you still have to monitor from time to time that no new pool found it's way in but it can only do that through bfgminer.conf file.My theory is that when your miner sees no more mork on slush it hops to pirate pool.

Anyway best of luck Wink

My BAT EXample :

bfgminer -o http://stratum.bitcoin.cz:3333 -u Eagle92212.1 -p xxxxxxx -S antminer:all --set-device antminer:clock=x0981
 
Worked so far.

However high speed workers are probably better targets.

What happened on mine (and just realized it was a brand new one just got in 10 days ago) was the item pulled away from the motherboard completely. Just fell off. Piss poor workmanship all done by computers.

90 days of Warrenty: If your antminer damaged during the warrenty, just ship back the units and we replace you a new ones.

Business plans/proporals, custom service and RMA request: info@bitmaintech.com

Might be worth a try too , seems like such a waste , parts won't get you much of your
money back.

Sorry everyone for starting such a heated discussion over repairs.

I just finished contacting my second local college and found some interesting things about the bitmain s1 antiminer.

The motherboards are NOT normal boards and can not be soldered on. Heat will destroy them. Guess this is the future of motherboards now. They are only one sided boards with everything added in layers over layers using some form of adheasive/electrical process to make things stick and connect.

What happened on mine (and just realized it was a brand new one just got in 10 days ago) was the item pulled away from the motherboard completely. Just fell off. Piss poor workmanship all done by computers.

Of course I purchased several off ebay as new and can't return them so I'm out, my bad I guess. Anyway bitcoin is always a high risk venture and always will be for the time being.

Guess will be selling it for parts for best I can get. Just letting everyone know the motherboards are not like TV or computer boards etc. That is why they don't repair them. If they work good enough to pass test that's all they care. I have 7 computers and workstations and only 2 have similar motherboards where items (at least larger ones) can't be replaced without microscopes and some sort of fancy adhearing processs etc.

Good to know , thanks for info ...

I checked the pics and it can only be SMD cap if that's the case , maybe you should
try emailing  few bigger and better equipped electronic repair services just in case
before you give up.Whatever process they are using to put components onto these
boards those processes can be repeated with right tools,I wouldn't give up on it
just yet , i bet these people could do it http://info.zentech.com/blog/?Tag=Electronics+Repair+Services

Hahahaha don't be silly  Cheesy

Thing that closed our shop was general price drop of new stuff to the point it was more
profitable to buy new then repair old and outdated.

And now the same arms race in ASICs for Bitcoin mining disappointing  Huh  

I'm not buying anything else until they build something like this :

I used to fix computer motherboards and graphic cards for years but I didn't read the thread carefully , true , things I that learned I got from a trained old serviceman.

I'm actually 34 yrs old and got at least 300 repaired motherboards graphics and PSU's behind me that had bad caps , mosfets , mosfet drivers or generally fried chips on them but I will just stop answering to this.

"popped out approx 1/8 inch and now shows as dead" doesn't spell blown , leaking and "shows as dead" can mean a lot of things.

I never read "visibly blown cap" part , only cap 1/8 inch out of the board ...

Direct current can zap you nicely and blown cap can be tested (it will say BAD) but some of them CAN hold a charge (LESS charge though).

There are caps that don't even look bad but are actually empty and not working ,  to be completely sure you need something that can measure capacity (ability to hold electrons) and to do that you first need to remove cap from the electric circuit otherwise
god will know what are you measuring.

Does anyone know where I can get a bitmain S! Antiminer repaired? Seems one of the caps or something popped out approx 1/8 inch and now shows as dead. Or is it just a waste and for parts now? 1st one to go bad. Cry
"Quote"

Sorry  Grin Any electronics repair shop should be able to do the job.BTW you can only test caps once they are completely out of the circuit.

One cap change + new cap shouldn't be too expensive (10 to 30 $ maybe) + they will
have to check everything else related so you'd be good to go.

If you have a local friend who knows something about it he could do it for you for free.

Never even saw one in real life , i assumed it had it's own PSU board.

BTW did cap just LEAP out of it's socket because of bad soldering or does is look
swollen or is there something leaking from it's top / bottom ? If it's true than it's
gone but don't assume that leaking 250 V cap can't hold a dangerous charge even
if it looks bad.

If cap is the only reason for it's fault then it would be no problem and you can do it alone with semi-good quality soldering iron but caps in most cases blow like that (when it's just one) due to fault of component BEHIND them that draw their power.
Is it SMD (Surface mounted-tiny tiny  Cheesy) of regular (a little less in size than 1.5 V AAA battery?
Anyway transistors and MOSFETs can be changed too with low cost but you are better of getting someone qualified to do it (like a electronics repair shop).

We are talking about BIG Antminer not USB version right ?

If you try to fix it yourself make sure that you use new cap with more Voltage I.E. if an old one was 1500 mF 16 V replace with 1500 mf 25 V.

P.S. If it is cap on PSU part of the machine STAY AWAY FROM IT , high voltage current is not a thing to experiment with unless you know what you are doing (If it's 330mF 250 V for example it's PSU cap for sure).They can hold dangerous voltages inside them even if you unplugged the gear , it takes days for them to be fully empty and fixing those things can lead to even more catastrophic failure.

Not been affected yet by this, thank you for heads up, but what I have done is put a block in my router from communicating with that dot addy, so hopefully the worst that would happen now is they would go offline rather than mine for someone else.

BTW Great thinking my 2 / and 1/2 erupters just stop working and submitting ANYTHING
to ANYONE  so if in case it's true Slush pool did great job at making this meaningless
for anyone to try again GJ

Just enable powersave mode in case this happens again and you  can't solve it so
you don't waste your gear for nothing.

This is what happened to 2 and a half of my usb erupters who weren't giving shares
to my workers on slush pool.It Was Friday night Central European time.Most likely it was my gear going bonkers but I checked for most usual mistakes and everything was fine except erupters although they were working full capacity weren't submitting to Slush.MOST PROBABLY it was my gear and lack of experience though Smiley

P.S. Only pool visible in BFGMiner was startum.slush , hope this helps ...
P.P.S. Rest of them (more than 70 % of all of my Mhs) was accepting shares from
Slush and working fine.

    You can save money by using any old USB Hub and old ATX PSU instead of
it's default power supply (even old 300 W PSU will give out at least 10 A which
is more than enough for 7 of any USB ASICs).
   You should open it first and check if any Caps on the ATX PSU are leaking
and replace them or just don't use that PSU.
    You just need to shorten BLACK and GREEN wires on ATX plug with a piece
of metal or copper wiring to give it a start and then solder RED Wire from any
Hard Drive / CD railing to 5 V on the HUB factory power supply jack and BLACK
(Ground) wire next to the red (one is enough) to GROUND on USB jack HUB side.
    From what I've seen all those USB ASICS tend tend to pull more power
than factory declared values and then they get really hot and pull even more.

PS. IF you have a multimer you can check which wire in HUB Stock adapter
is 5V by setting it to 20 V and then putting one pin (any) inside the jack
and the other on metal around jack , set Multimer to 20 V and put the other end of multimer (+ and - , don't matter at this point) at the end of USB Hub PSU Jack wires (ground will show 0 V).5V is inside , ground is metal around iton all models I'seen so for but always check twice before soldering the cables.

3 usb Erupters and 1 U2 Antimer are all on one hub now and I don't see them
crying for power or getting too warm (adding some cooling on them , like a passive cooling used for N/S Bridge on old motherboards with a kitchen rubber or two is also not a bad idea).

Same thing can be done on AT PSU but you don't have to shorten GREEN and BLACK wires as they mostly start by themselves and have a build in switch
Just read 10A or more on +5V , open it and take make sure caps don't look blown) and you're good to go  Smiley

Actually I was thinking to get my old HeatGun and some Cryoflux and go back to fixing all those old ATI cards with good MHash/s rate as their main flow is generally too much heat even when you don't overclok them so chips tend
to get too hot and actually desolder slightly from PCI-E card.

They still sell here for a hefty price due to litecoin mining.They will mine Litcoins
and I will mine the Litecoin miners  Roll Eyes

P.S. Forgot about shipping cost entirely tnx for the reminder , it would go
on top of import tax which can be anything from 20 to 50 %  so no ebay or
amazon for me Embarrassed

I had the same problem but then I read that it's calculated at an hourly rate and now it's 10 time faster but important thing to know here is that as long your client (miner program) is accepting the new blocks you are getting the reward even if you don't see it right away.I calculated manually  Cool You can see more info (in fact you can see ALL the info) in your stats.

If you're accepting shares you are getting reward.

P.S. Finally found a cheap 2 GH U2 Antminer  Roll Eyes  Roll Eyes  Roll Eyes

Generally average output is better than on other more marketed  servers.
One thing I like about it (apart from nothing hidden part) is that slush is
configuring the pool to work to the optimum and using all your resources.

If there was no pool like this somebody should make one  Grin

I can only make an assumption that mining site and pool don't just build and
protect themselves on off-the-shelf parts so all work is done by Slush.
 
Almost bought 2 x 2 Gh/s Antminer today but the price here is still way off so I
have no choice but to wait for things to settle down.  Angry

   I've been mining for a month now with 3 usb erupters at around 1 Gh/s
and I can recommend slush pool to everyone as this is is the most honest
pool I found so far.
   "Luck" is not really a term I would use for describing anything that has
any computer generated numbers behind it , luck is when you throw a coin
in the air and it falls on head or tails or when you roll a dice but slush is
generally making sure to the best of his (theirs?) abilities to make sure that
everyone gets a fair share of that "generated" luck.
   I tried 50BTC BTCGuild , mining PPC etc etc and this is only pool not hiding
anything from you as all other pools are hiding the blocks you found and confusing you with steady income that is less and less in time to the point of nonsense.
   Also , Bitcoins , in my opinion , ARE NOT MONEY , they are just a big pile of
nothing that people believe is worth 500 $ per unit at the time of this post.
   Nobody knows for sure where this goes from here but as I upgrade my gear
slowly I will keep on using slush pool if it survives as it's the only honest deal
out there I found , also , mining is not work and it doesn't take anything from
my regular computer experience.
   On slush pool at least I know everyone is looking for blocks and solving them
and sharing the profit fairly according to their speed.
   Never forget , pool owner is THE OWNER OF BITCOINS MINED so trust that
the pool owner is an honest guy(s) is the most important thing for me and this
is the only pool I trust so far.Way to go slush !  Cheesy
