Homemade tin foil shroud with 2 x 250 CFM extractors from Home Depot (piped out a basement side window). Just enough to extract heat from 2 x S7s and 2 x Neptune cubes exhausting upwards.


Inserting setup don't know that I have seen to close to this before on neptunes.  Do you have more pictures of the foil shroud? I would love to see a little more of it.

Thank you for sharing!



Not at the moment. But it is really very simple. I just placed and secured the 2 exhaust fans over the top wire shelf and built the shroud around the fans. There is a window behind the shelves which I boarded up, painted nicely on the outside, into which I installed 2 vents which are ducted to the fans.

this last pic is SO WRONG ...it is so mesmerizing thou...it just wants to suck me in....(must resist argh....) it is a CHAOS TALISMAN
of some type....LOOK AWAY.....(it burns my eyes....)


A chaos talisman, I love it, lol!  I though the same thing when I saw that pict, it's like a little ball of wires that somehow mines.  GOT WIRES?  Grin


I dig the "thing" to power the 3 S7s, but shouldn't you cover up that copper bus bar to prevent accidental electrocution?  Looks terrifying!  I hope you don't have a cat...

Nah, 12v is too low to get even a shock from, much less getting electrocuted. I think you start feeling electricity somewhere around 50v or so. This is assuming dry skin, of course. Wet skin would be lower. The only danger would be if something made of metal were to short the 2 bus bars out.

For the most part you are correct.  Just do not wear rings when working with this.  Seen several people have cooked fingers from letting rings hit bus bars back in my DC datacenter days.

Ha! Never thought of that. Probably since I don't wear rings, so I'm safe. Smiley

Figured I'd post this here for people who don't follow the S7 thread.

Decided to "make a thing" to power my S7s Grin. Hope some of you will appreciate this!







2X 2000w server PSUs sharing the load of the 3 S7s. Will shortly be replacing the PSUs with the 2500w versions since I'm actually pulling 4400w DC from them right now, which is 200w over their rating on each.

I've adjusted the voltage output to 12.6v on the PSUs.

Wow, looks homemade but effective. Very impressive! Do those fans do enough to cool those machines or you need extra fans?

I agree it's very impressive.  You no doubt put together a nice PSU for a decent price.  I like the look aswell.

Eventhough I like the look those exposed bars scare the heck out of me.  That is a lot of power running though there.

Prelude I really like what you did there.
When I use my 2000BBs stacked together I strap the fans using tiewraps and then my cables run straight off the GekkoScience break out boards to the miners, but I like your implementation of the separate connection bars.
Once cable is only 12v, but you are gonna get a nice little bump if you short that to ground with a sweaty hand my man. At least run some silicon, or actually, you could put a small piece of cheap plexiglass across the top of the bus bars. Terminal strips that long aren't that expensive either, but I know if I'd built it I'd be happy and proud of not needing other materials. You probably had everything laying around Smiley
Still though, some terminal strips with side guards would be a big bonus.

It is a good looking setup though for 4k watts. I have half a dozen in the closet I need to make a project with.
At the moment everything is running using the 2880s w/ Jabbers boards from Finsky.

Sidehack and Finsky have both treated me well. I've never had a bad experience with either of them with transactions, or with Jabber or Gekko's equipment. I do like the options on the GekkoScience b/o board for the 2000bb as well.

I think I am going to do what you did. I copy good ideas all the time and try to improve them.

Code:
A BTC mining experience with the best, proven record. 88 weeks + at 106% + and 181 solo blocks as of 05-29-16.
I will tell you a bit about two people who are unmatched in technical experience, troubleshooting, knowledge and time spent
online in the BTC world supporting not only pool members, but the entire community.
CGMiner is the software used on more mining equipment than any other software, and is written, maintained, with continuing significant achievements by these same two gentlemen.
The Pool and Database software used by many pools is written and maintained by them.
It is constantly under enterprise pressure. It handles multiple attack vectors and evolves staying ahead of every other cobbled piece of code in use at any other pool.
This is The Total Package in BTC Mining Software:
Kano of THE PPLNS CKPool located at www.kano.is
and CK aka Con Kolivas of THE solo mining CKPool located at http://solo.ckpool.org
If you are not mining at one or both of these pools you are not mining, you are searching.
Get serious regarding your numbers and evaluate the data yourself: https://bitcointalk.org/index.php?topic=1338693.0

On another note if you use the forum trust system as a gauge for buying or selling please take a moment to evaluate my personal opinions and consider how much weight this system sincerely helps anyone.
https://bitcointalk.org/index.php?topic=905210.msg13227629#msg13227629

Trust Abuse by dogie against many members is rampant.
He attempts to use it as censorship against anyone who dares call him out when he gives bad, or poor information.
He has given people advice which could or may have caused harm.
He offered to remove negative trust against me if I would post specific text. The text he requested is not truthful and I refuse to be extorted and blackmailed.
So should you.
Do your own investigation and confirm yourself if this is a one, two, three, or even four or five people incident and maybe he could claim truth or misunderstanding.
Once you see how many people have been abused by his methods I believe the truth will be obvious.
Everyone has an issue here or there, but few have so blatantly abused this forum's trust system.
Take Dogie's rating against me for example.
I have a blemish free record and have worked with many of the most trusted members of this forum with positive outcomes.
I have and would never buy / sell anything with dogie.
Be safe and don't use dogie's ratings system of any type. They are skewed by money and personal vengeance against honesty regarding his behaviour and comments.

what's the purpose of the busbar, and not just connecting the PCIe wires directly to your breakout boards?

obviously the load-sharing provides slightly better stability/overhead, but for ~$20 of extra materials and at least an hour of added assembly adding another PSU seems simpler

24" PCI-E cables with 16AWG wires and stripped ends - great for server PSU mods, best prices https://bitcointalk.org/index.php?topic=563461 also selling 6" M-F-M PCIe splitters and PCIe-PCIe
No longer a wannabe - now an ASIC owner!

I'm really not worried about the bus bars. I've got 2 DPS2500s coming in today, turning the setup into a 5000W beast instead fo 4000W. Once they're installed, I'll be putting everything up on a shelf out of reach. If it was somewhere where kids or pets could get at it, I'd definitely cover them up somehow, but as it is they're in a garage where only I have access.

They're definitely a pleasure to deal with, and both have great hardware to offer. I have a slight preference for sidehack's boards because they have a lot more options available on them, for example the load sharing, 5v for controllers, and fan headers with speed control.

Make sure you send me some pics of your setup if you make one too!

I needed the bus bars to use load sharing properly, need a common bus between both PSUs to pull juice from them equally. I went with this setup because the loading wouldn't have been equal across both PSUs while powering 3 S7s. One PSU would've powered 5 blades while the other only 4. That would cause one PSU to be overloaded while the other one was under utilized. I guess if I had the 2500BB to start with, I wouldn't have bothered, but it was a nice little project that I enjoyed putting together. I learned from it, and the next one will be more efficient.

So, I made another thing yesterday:









The 2 PSUs are PFE1100 units, pulled from an old cointerra IV box. Thy are really incredible little PSUs, 94% efficency at 100% load. Blows the socks off of every other PSU I have. Up to 8 of them can be linked together if needed, providing a whopping 8800W of pure efficiency.

You may have noticed the the light gauge black and white twisted wires connecting to the 4th cube. Each pair goes back to a breakout board on each PSU. Their purpose is voltage sensing at the load, and allow the PSUs to dynamically adjust their voltage level to compensate for voltage drop across the wires.

The 5 cube Titan (420MH/s scrypt, 1 dead die) makes for a prefect house heater. It's very quiet, which is a requirement with my better half. She didn't even realize they were in the house until she saw them! Temps have been warmer than usual, and these guys have been enough to keep all the heating in the house off so far. When it gets cold enough (below -5c constantly I guess) I'll bring in reinforcements in the form of a 6 cube Neptune.

Its been gutted.  All that is in there is a Raspberry Pi and the original power supply powering the Pi.  

EDIT: and as of last night there is now an Antrouter U1 there just because I thought it was neat.

They're made for it, so long as the load sharing pins are connected together allowing them to communicate with each other.

Hmm, that's interesting.  I have some of these left over from a Terraminer.  Sounds like you can basically make a "2200w" power supply out of them. Grin

Actually, you can make an 8800w psu out of them. Smiley up to 8 can work together in load sharing mode.
