Preparing small S7 setup - Grandpa's basement

[cniht]

Yeah I'm hoping for a very long and cold winter.  Not as far north as you but in the North East US.  My electrical rates are twice your own, which doubles my own ROI.  But not having to turn on the heater this year could also save me $600 USD.  And since I started at the end of summer mining I'm not paying full freight on my cooling costs, with the 30C to 35C heat we've had this year.

[torepia]

Grandpa wil go bankrupt on the electricity.

I was just thinking the same 6 S7's would be over 7k watts.    Even if he has cheap electricity hes paying a lot for the cooling he's getting from these.

You really should think about paying your grandpa for some of the power.  I do like the setup.... just man that is a lot of power to make someone pay.

Haha  

From first post: "So, I've been mining in my grandpa's basement since early 2013. This has been a win-win situation overall. He gets free heat (his whole house), and I get a location to host my miners. ^^"

To clear things up:
I'm paying everything, even the building materials, so I'm NOT leeching on my dear GP!
The thing is, this is a fun project for the both of us. And it actually gives him something to do during the day! Imagine how fast you rot, if all you do is wake up at 5am, and watch TV all day.. (when ur 87 years old).

Here he is, cutting like a boss:

And yeah, he's using his living room table as a workbench! ^_^

When you say your paying for everything does this include the electricity?  You didn't put that.

I like your project looks like coming along nicely.

Sorry mate, I'm paying the electricity! xD
Thanks, I'll keep this thread updated on the progress.

Ok I don't feel bad for the grandpa then . I was thinking he was getting stuck with the bill.

Still very nice project please keep us updated with pics.

Small update:

Intake "vent":

Outtake:

I'm a little worried about the air-flow, will it be enough to cool 7200W.. time will tell!

I got a 400 m3/h exhaust fan mounted on the "outtake". The idea with the T-split, is to be able to open/close the vent on the left (inside of the house). This way we can hopefully adjust the heat inside. The hot air will then flow into the basement, and rise 2 floors up.
If this vent-idea don't work out, I'll mount the exhaust fan directly on the outside wall vent. And add another separate fan to the inside vent, giving me 800 m3/h exhaust (with passive intake). I can direct the air from the inside wall vent, to another exhaust vent if necessary.

This is the type of rack I'm going to use:

And I'm gonna seal it with plexiglas like this, gotta love MS paint:

Cut holes for the miners & PSU. And make it air-tight around the rack as well. Hopefully this will help direct/force the cool air thru/around the miners, and create some extra pressure on the exhaust.

I can slide the top board on the right side off, to access the window:

Heat test with 4600W:

I never went above 32C, I actually think this will work, with some tweaking!

I got 3x 16A 230V circuits ready for 6x S7, two on each.

Looking nice.  On fan how is that routed?  It it pushing and going both left and right on duct behind it?

Thanks for sharing updates they are fun to watch.

Amazing idea of S7 setup

[Betwrong]

This has been a win-win situation overall. He gets free heat (his whole house), and I get a location to host my miners. ^^

Looks like a nice deal! Can't wait for the updates!

You said you'd been mining from 2013. So was it worth it? I mean really, I have couple of friends who's mining with Antminers and they are saying if you can have back the money you've invested - that is the best you can get.

[mindrust]

Have you gained anything from mining since 2013? Or is it only for fun?

The biggest danger there is the ROI time, just pray for S8's to not show up before you ROI.

I don't think praying will help.  I think a S7+ or S8 will show up before most ROI.   I doubt they wait for all these S7's to roi  before next model.

But I could be wrong.

[busyviable]

keep the updates coming! really interested in these kind of small scale home-made projects

[Nexious]

Will be interesting to see the setup once finished! Let us know how you get on.

Update:

Almost done, need to fix a permanent door solution:


Bitmain's APW3-12-1600-B2 PSU:

Starting two of these at the same time on a 230V 16A circuit, will make it pop! ^^ You need to cycle-start them.


"Rack" in place, testing Bitmain's PSU with S1's:



These two shelves will contain the S7's probably:

Going to seal it up so that all the fresh air goes thru the miners before entering the room.


Power draw from 2x S1's, overclocked @ Bitmain PSU:



When I used multiple ATX PSU's to power miners, I always used "add2psu", to merge them together:



PSU comparison:

You definitely don't want these PSU's in your bedroom

Thanks mate! It's pushing, and going both left and right. I can adjust the vent to the left to regulate the heat inside the house. I know this T-split is killing the air-flow, but I actually think its gonna work anyway! We'll see ^^

It was worth it. I was lucky with my timing I think. From April - Nov 2013, i mined LTC valued at 20k$ (24k in todays value, strange how things change like that.. :p) during peak in Nov. I sold half my coins, still got a couple of hundred ltc left..^^ I guess I could be bitter for not cashing out everything, but hey, I'm a believer!  

Edit after trip down memory-lane:

This was my first LTC block:

Good times! ^_^

I installed Minera Dashboard on a debian VM, the install was a breeze.


You can easily spot the miners who are unstable, and might need some freq adjustment, I love it.
