It's such a grey area to define "stealing" your electricity when it's included in an agreement.
In any rental you really can't modify any wiring and certainly can't increase your supply legally, meaning the miners you could run *safely* would be relatively paltry and the consumption pretty low, not to mention the fact you are averaging your consumption with a whole building and I have a hard time really calling it theft.
All that said, doing anything of the sort without consulting the landlord is a risky venture as I'm sure some would see it as grounds for eviction (operating a business in the unit, wiring/fire concerns, etc.)

Alright, after 3 months of research and planning, some seed money, and an immense amount of elbow grease I can now officially call myself a Miner.


Welcome, to my Wizard Box!



Framing the box, mounting the electrical (8x240v, 2x120v, 1xCat5e)




Sub-panel run from main (60A 240v line to 125A sub) wiring finished and drywalling the interior



Soundproofing/Fire-resistant insulation



Box closed (for now, still have to finish the lid)




Woo! Mining!



Ductwork going in

Intake manifold



Exhaust manifold




Cold air intake and 8" exhaust (Still have to add the T to draw from the house cold air return directly above the 5" duct)



Miners and power supplies arrived in 3 days flat.




FULLL POOOOOWWWEEEEERRRRRR!




All assembled, sound is minimal, still have some work to tie in the exhaust to both the house heating and an external exhaust for the summer. All told by far the funnest project I've undertaken in a long time. Hoping to get another 4 miners by the end of this year, with the halving coming up I'm just waiting to see what happens to prices.

Wizard box Update 1

Hey guys, had these puppies running at 100% for a week now, I couldn't be happier! Still more work to be done to add in the 8in outside intake and hopefully add a second centrifugal fan as a failsafe and so I can bring the outside noise down.

Finished (Phase 1) 5in outside air intake + 5in inside air intake = 8in intake, 8in exhaust with ~1200cfm centrifugal fan I managed to snag used for $75  Cheesy




Replaced useless laundry room window with 2x8in manifold




The door needs to be finished, same with the lid. Sound is low enough once I build the laundry room door you really won't hear it through the rest of the house.




Half occupied with my 4 s7's





Mess o' cabling 




MINING FACT: In Alberta (Pretty sure it's actually a North American standard) you *CANNOT* wire up a standard 5-15 outlet with 240v and have it pass an inspection. We wired these up with simplex 240v outlets and built these adapters which are entirely acceptable to code.


Crowded exhaust





Always make sure your 240v breakers are properly ganged!


Going to be a few weeks 'til I put any more into the rig, waiting to see what the prices on these single fan s7's do because they would be a perfect fit in this box.

Until then, good mining guys!

Mikestang's right. If all the posts are about non-bitcoin mining hardware I'll just close the thread. You can start one in altcoin mining.

Your kidding right??? BTC mining at home is DEAD...all we'll see is is the same ol ASIC in a closet stuff LOL

The GPU mining rigs are creative at least,no matter what coin is being mined  Grin


As CLEARLY evidenced by people posting in this very thread, BTC home mining is not dead. Statements and opinions regarding the profitability and speculation of bitcoin hardware belongs in Bitcoin Forum > Bitcoin > Mining > Mining Speculation
Thanks!

No complaints if you lock up this thread and we can start a new one, more than a few users tried to get this chatter moved to the proper threads but apparently some people just don't understand how a forum works. Thanks -ck!

I am all for people posting their work on these forums for others to appreciate or criticize, I just feel pretty strongly it should not take an admin to MOVE YOUR HACKJOB GPU RIGS TO THE ALTCOIN FORUMS WHERE THEY BELONG!
Y'know, so that people looking to this topic for pictures and updates of BITCOIN mining rigs can find what they are looking for. I'm pretty sick of popping on here for an update or some feedback and seeing the thread hijacked for fly-by-night ETH miners trying to sell their rigs that any noob can slap together in a couple hours.

what brand of exhaust fan is that? been hunting for a high cfm fan but the max i find for 8inch is low 700


Good catch, it is an Elicent AXC 200B which *is* rated for ~700cfm, I believe I got that confused with the cfm rating of the ductwork (~1200cfm ideally, like more like 1100cfm with the 90's and duct runs accounted for.) Which I will be pushing for with a second fan on the intake side to boost cfm, add in redundancy should one fan fail, and cut down the noise by running each at ~80%.

I've played with the idea of adapting in a 10" or 12" fan which would push 900-1200cfm but I can't reconcile that cost, any ductwork over 8" I have to deal with a distributor and that's also a huge pain.

I haven't had much chance to play with pos intake vs neg exhaust pressure, the way my box is setup I'm definitely keeping the exhaust suction a bit higher because there's very little downside to pulling in indoor air vs. the negative of pushing outside air into the box and into the house. Something like that will come about in a few months when I have to look at mixing the inside and outside air reliably to feed the miners air above 10°C during the winter and capturing and filtering some amount of exhaust air to feed the house.

The way you're setup I can definitely see the advantage of building a box just to control the air a bit better and cut down the noise a bit,  just remember to measure once and then cut everything, that's the trick the tradies won't tell you  Wink

I haven't updated the pictures in a while, I've made some changes to the ducting system (Now 2x8" intake and 2x8" exhaust).

Total cost to build my enclosure (w/o wiring and fans) ~$400. It helps that I got most of the ductwork for free off of Kijiji Cheesy

Re: Bitmain's Released Antminer S9, World's First 16nm Miner Ready to Order

.....

Anyone out there using S9s successfully with zpool?

I just attempted to with one of my S9's it didn't work for me.

you probably have to use a proxy.

this is what i use
https://github.com/Stratehm/stratum-proxy

Shortened as so long but I just tried zpool and am having no issues mining direct to it.  Will test for 30 minutess or so and post a screenshot but right now it seems to work just a tad slower my batch one is getting: 13,797.82 but have only ran for 3 minutes.

So looking promising as far as running it.  Is zpool really paying that well?  

With stratehm it is noticeably more stable for S7 and S9, the S9 is significantly better than the S7 and I have never had my batch 3 lock up. The servers are not tremendously stable so expect to get 0.0002-0.0003 lower payout than what is listed by way of failovers, but you'll still get some good profitability.

Seems to be same results after 30 minute's.  No issues mining direct from a batch 1 S9.  Site is possibly slow though as in 30 minutes it show's hashrate much slower on zpool site.  Guess will see in a while if it catches up hopefully.:


I did lose a little hash compared to a normal pool (I've tested many on it).  Has anyone used this pool much is it really paying out so good consistently?

You'll find my miners there when profitability  is doing well (>.0018), no complaints all around. You'll sometimes find profitability will get mis-reported a bit due to the exchanges they use, but it's never too bad.

SHA-256 ASICs will work for any SHA-256 algo altcoin.

Keep in mind the most recemt ASIC's have a tendency to choke on the low difficulties presented by most altcoins, running all possibilities of given hashes + nonces and sometimes crashing the miners.

Coins I know of with reasonable difficulties (>1M):

Aurora, Digibyte (SHA256), Unbreakable, Terra, Neos, Digital (SHA256), Maza, C-Bit, Join.

Keep in mind profitability for these altcoins fluctuate wildly, check out www.zpool.ca.

im installing it now.. im guessing when i run it i connect the s7 to RPI-IP:3333 instead of mine.zpool.ca:3333?


Yup, you got it.

Well, it was a fun 25 minutes (while it lasted); let me know if you ever get sha256 stable..
Code:
[2016-07-26 08:14:52.665] Proxy 0:mine.zpool.ca:3333 failed, attempting reconnect

nice and stable with https://github.com/Stratehm/stratum-proxy

i too cant get my s7s to run on here.. will this work on a rpi? or do i need a faster pc?

i mean i see the install for the rpi, but is it fast enough.


No reason for it to have an issue running on an RPI. This is still my plan in the near future, rather than using my gaming pc to run the two stratums. It takes about 200MB of RAM per server instance, but really doesn't take much CPU if set up properly.

Is there some advantage to ckproxy that stratehm does not implement? I don't think I could ask for much more functionality.

Not really an "advantage"; however, the fact that it's written by the same guys that wrote cgminer (and BMminer being a bastardized version of it) , would suggest that the connection code from proxy to miner would have to be as good as it gets in ckproxy. That's not to say that one is "better" than the other, just that that ckproxy/ckpool can't be "bad" at handling the connections.

Can't argue with your logic. In any case I have thoroughly tested stratehm with S7/S9 and zpool and it is significantly more stable having a stratum handling failover as opposed to connecting cgminer/bmminer directly. It's far from perfect, but I know crackfoo is still trying to get the sha256 stratums more stable which, with either method, could potentially solve all the problems.

nice and stable with...

If it ain't stable for an S9 using ckproxy, it ain't stable for an S9. Undecided

I'm provisioning a new standalone stratum server now to see if there is any improvement running on a high performance ssd vps.


Stratehm proxy is fantastic, my S9 (B3 w/ updated firmware) is more reliable than my S7's on zpool, have only had to reset it once. (This was most likely due to messing around and testing stratehm proxy to a tethered cell-phone and not due to zpool, but there it is.)

Is there some advantage to ckproxy that stratehm does not implement? I don't think I could ask for much more functionality.
