I dug around in the threads and on the net and can't find a powered usb hub that can handle twenty or more. Can someone point me in the right direction? I would prefer something that is somewhat compact since the wife is pissed off at the noise of nine s7's running in the garage, so I want something a bit more fun to tinker with when I am bored.


Ufo

*edit it was getting to be a LONG quote so shorted it rest is above.

er forgot to mention it probably was (inspector on hand etc) a 'city' ordinance ...univ town..thus landlords probably electrocuting self....but that was the rate ..(or I looked like a soft touch)

but yeah if i'd know what you did (duh) i prob would have done the same...as it was i squeaked by.....so its prob for the best

for those of you just needing a 32 port panel ..the charge for that complete was 500 bucks..guess that is more common ..thought they'd screw me on that but probably the 2500 bucks is the electrican's are taking in to account ..if we have to stand around all AM talking to the xcel guys till the electrical inspector shows up or not....this is wtf we are gonna charge for service install in this town

but if i do decide to do it someday I'll try your method ..but doubt it now so ..hell at least saved 1300 bucks compared to you (dumb and lucky always my 'idiot' back up plan)

 

You can safely get the firmwares you want from Bitmain's website. https://bitmaintech.com/support.htm?pid=00720140930114518599JXGHWWD80660

It is possible to flash your sd card to a old version and get volt control. If you use the latest Firmware that fix most serious issues, then you will lose volt control. The way to keep volt control while having smit's firmware + the proper cgminer version is convoluted to say the least.

So, who thinks I should put a cap on how many S5 boards a person can trade for pods? What should that cap be? Five? Ten? I know right now only 8 survey respondents have selected the straight trade option, but I'm also told that the market value for dead S5 boards has been increasing since this thread appeared because people are buying in anticipation of the opportunity to trade.

Should I worry about a cap, in order to prevent some folks from being taken advantage of by a few opportunistic individuals? Or should I not care and let the market fend for itself? I don't like being party to someone getting screwed, but at the same time it's not my job to be the dick police.

Also, y'all will be pleased to note that I made absolutely no progress on this or any other project today.

Yeah, market for the dead boards is getting rough. Like REALLY rough. I haven't been able to get ahold of the amount of boards i told back then (just 1) and everyone down here on my country is stashing them Guess it will be great for the project, maybe i instead will arrange a group shipment and buy-back of the extra pods.

Kinda nebulous atm on how i will handle it i have at least 4 peeps on my family interested on the pods, plus a lot of people on a miners group talking about these babies.

Speaking of resources, i've just got 1 dead board from a friend, there's about 15 more incoming my way, that would net about 16 boards "if" the project goes trough.

As soon as i have them all, and you say "go" i'll send'em.

yeah  as of this morning the 21st no one has said they have confirmed tracking for Batch 2 or 3.

the clock starts ticking on the 25th of oct when it comes to these batches. My guess is they will not ship any earlier then the 23rd.

Back to batch 1 does anyone have a batch date on the 20th of sept or 21st of sept?  If you do have you got any 'real' shipping info?

I do believe they were up to the  Sept 19th dates on batch 1

it can only be profitable on new altcoin if you instamine with tons of hashpower rented for 3 hours max, or even less if possible, because the outcome of a new alt is unknown there is the chances of a big gain

i would not try it for anything else, but it was profitable with cointellect, very profitable

Finally , Avalon get the Avalon6 spec in public officially .

 With electric THAT bloody expensive, your probability of achieving RoI on ANY current or recent miner is pretty much zero - in fact, the ONLY currently available miner that would show ANY profit at all would be the S7 (possibly a SP20 if you clock it WAY down for max efficiency or an S5 if you can undervolt it enough - many S5s CAN NOT undervolt at all though), but you'll be spending so much on electric to feed the miner you'd never pay the thing off or even come close.


 NOTHING other than ASIC has a prayer of being profitable for Bitcoin mining - Pi don't use a lot of power but they would hash in the KILOhash/sec range, even slow ASIC are multi-digit GIGAhash/sec and current ones are pushing into the multi-TERRAhash/sec range.

Your Pi would be trying to compete with the Thrust SSC in a max-speed race in your Model T Ford that has 2 cylenders not firing and thinking you have a chance of being competative.


 All current miners and most recent ones already have controllers built into them, no need for a Pi or similar to run them with.


 The Avalon 4.1 was LESS efficient than the Antminer S5, which was LESS efficient than the Spondoolies SP20 could be set up for (though the SP20 at stock settings was both a little faster and a little less efficient thatn the S5). I'd tend to ignore it unless you can get one VERY cheap ($200 or less + shipping).


 New miners have been anounced both by Lketc/BW and by Avalon - I'd wait a month or two for them to actually show up with real avaiability and pricing before I made a decision.

 Innosilicon also announced they achieved tapeout some months back on new gen SHA256 (A3) and Scrypt (A4) chips, and they have a history of building miners around their own chips - I expect to see something out of them at some point too, probably late this year or very early 2016.

If you can see it as an long term investment and if you can deal with it's opportunity costs (of not having that amount of money for something else right now or in the near future) it absolutely can. I reduced the overall energy costs in my specific case by 15-20%.

So if you are paying ~ $0.19 per KWh you can save in my case 3-4 cents per KWh -mining can be profitable again @ 0.16-0.15 cents / KWh.
With paying only $0.08  - that would save you 1.2 - 1.6 cents. Paying 0.068-0.064 instead of 0.08 is more or less negligible. That doubles also the time for a ROI.

See what I mean?

My idea would be stock fan cooled.

Twenty four hour run.

Most shares for the one stick.

Have to show a screen shot of hashing on hour zero and hour twenty four.

In theory cgminer would show run time really close to 24 hours.

Crypto glance would track shares


Lastly everyone could use suggested diff of 16

Most shares wins.

If cgminer crashes and does not show
24 hours disqualified.

a I need to think of a way to cheat what I just wrote.

B if we like this contest later on we could do a modified any cooling method for a second contest.

C if you can figure a way to cheat the contest let me know.

Should be possible to port mainline cgminer to it so that it can run all types of USB miners.

and now with the pretesting I think they took a few hundred offline today.

Blocks dropped to 128 or so after yesterday doing 169.

So from the data I see bitmaintech takes a few hundred offline then puts a few hundred online rinse repeat.

Maybe we don't do five or six percent like we thought maybe we do more like three or even two percent

So no point buying a batch 3

More than likely, whatever GH based on a value you get now will be worthless in a few years, because of raising difficulty, at least at hashnest, because its fee is based on the profitably of the unit its tied to ex; S5.

Otherwise you'd need a system where they devalue and overtime fee per GH is lowered.

Use multiple ones, 1 usb costs about 3-4$ here. You can easily buy 10 of them and then put them in a faraday box to shield against EMP charges.

I dont know about renaming, certain formats have different encoding and it might fuck up the data. Like if you rename a .mp3 to .txt, and then back to .mp3 it wont work anymore.

Your account gets locked if you use the secret question to change the password on your account, not just changing your secret question through your profile. As long as your account isn't hacked/you forget your password, you shouldn't need to worry about this.

well some thing i just did today got it working i did changer my ip but its all good now

philip we (or you its your show) should think about contest rules?

say only stock sticks but with aftermarket cooling. that way most anyone can participate?

I have Execl too , but being the home owner i claimed i was doing all the work myself found an electrican on craigslist to do all the work for 1k with my supervision of course.  Paid $500 for parts and $300 for the inspection permit.

so yeah with the permit it was actually $1800 .  And i dont know why they told you that , on the pre-inspection the inspector was fine with us doing all the work over the weekend then comming to inspect it later during the week.
