thanks! i really like your idea with the spacers. Where did you find all those?

i found them here:

http://www.aliexpress.com/snapshot/6261180047.html

edit: Keep in mind these boards are undervolted to 0.74v - 0.79v and without headsinks they will get hot, but the 2 fans keep them at aprox 45 degrees celcius

similar standoffs are available on amazon - some with prime shipping. just takes a bit to find the exact one you want. but start out looking for M3 standoff

I am considering breaking out my dremmel tool and modding a standard (albeit large) PC case for my project. Cut out all the inside casing, glue some rails on the sides to secure the blades on,and fan the crap out of it front and back. My biggest three issues at this point are:

1) Noise

2) Heat

3) Power Consumption

My ultimate goal would be to be able to consolidate all of the blades to one or two housing units (whatever that ends up being) and then doing my best to undervolt them in such a way that they are functional but still within the 400W threshold. It looks like you have found the sweet spot as far as the undevolt goes, now we just need to tie it all together with a central control board.

Yeah I could tell you had them under volted from the specs you posted. I had heat sinks I ordered from eBay on my first antminer and they kept falling off from the heat. I guess this won't be an issue with the blades at a horizontal flat posture. I also noticed your heatsinks were black where mine were silver...where did you get those? I found a guy on ebay who has high performance 120 mm fans for $15 on ebay. I used those for the secondary fans on the standard s1 configuration. I also found this case wall with about 9 fans on it that are powered with a standard pc power cord. I disassembled it so the fans were loose and took off a couple fans that had warped ball bearings. Worked out great...as long as my miners were stacked close together which I wasn't a fan of (no pun intended haha). How many do you plan to stack together ?

the heatsinks i got from here:

http://www.aliexpress.com/snapshot/6082979423.html

but i only have it on 4 blades ( 3 in the current setup in the picture)

the rest 16 blades are without any heatsinks

edit:

im going to try and put them all inside a 4u server case with rpi and power supply and all :-p wish me luck :-p

I saw this thread when it first came out but I was still actively using my S1s. I just ordered the upgrades and now I want in on this project. Reward or not, this is an amazing opportunity to revitalize old tech! Very impressed with what I see so far. If I can assist anyone in materials or other support feel free to email me here or at my email on my profile. I have a ton of hardware experience but am admittedly a dunce when it comes to hardware programming. Once you get to the linux side of things I am good to go,but chip level stuff...I am a chimp.

welcome :-)

my experience isnt that big either, but its just a matter of try try :-p

I have four boards (boards only) from the late 2013 batch. (will check the version at home) I will modify them with 10K adjustable Pot, this week.

Should be able to test many Volt/Clock settings once i can connect them to my PC. (I don't have any CP2102 interface).

I will stack them as ChoasiTec did. great idea ! Cheesy

Once i have a stable setup, i will change my last 4 blades (which are full S1 miner atm).

Can't wait for the control board !

ive order 80 10k pots :-p had the same idea, and since i have 20 boards :-p (I want to be able to set the chip volt at exact voltage instead of pencil mod which is aproximate)

i also have a server case 4U hight, thats where i want to put them all in, including psu, and rpi :-)

Temperature 32°F it is reality?

Nope, it reports 0 degrees because it cannot measure temperature

im guessing my boards are running at aprox 45 with the 2 fans

Well, ran out of cp2102 usbs

edit: now stable at 252 GHs
315 Watt / 252 GHs = 1.25 W/GH

wow

edit: I suppose it is without any cooler

i have a fan, and that helped, but im adding an extra just in case

Still have 15 boards left...

Your prototype will be posted on wednesday. tomorrow will be bank holidays for end of WW1.

Awesome :-p

I had a look at a few things regarding the hardware of the blades.
Each chip have an address defined on 8 pins.
each board will have the following addresses:
00-08
10-18
20-28
...
F0-F8
Linking both boards in serial shouldn't work since there will be 2 chips with the same address.
And I'm not sure parallel would work for the same reason.
If I understand correctly, the chips aren't pushing the results but are waiting for the result to be read from them.
if you ask for chip A8 result, you will have 2 results returned, and I'm no sure it will be something readable by software or some random garbage mixed from both chips.
Initializing the chips might not work for the same reason, since you are expecting an answer from the chips.

I get them to initialize, and it reports 64 chips, but the test, where it sends a known nonce to the chips for testing, only results in timeout, so for me, thats a dead end street..

I've just received a few parts to move on next step and work on the 8 hashing boards controller.
I'll also soon be able to make my own fine pitch mylar stencils. It will make the soldering job way easier.

Perfect :-)

Next on my worklist, something else related to the antminers. (sub 0.9w/GH at the wall on first gen chips)

my tests i have pushed them down to 1.1 watt/GH on the wall, and the chips are running with 0.74 - 0.79 v but im currious to see what you have in mind :-p

Has anyone thought of using a BusPirate to pull the info from the original Bitmaintech Antminer controller?
http://dangerousprototypes.com/docs/Bus_Pirate

it is first time I see it

but it has one UART so it should serve at least one blade

in that case it is quite expensive solution
better to make (buy) usb hub with 2 or more cp2102 and put it into Rapsberry, it should work

its for analysing the data going to and from the blade
