With the addition of the wireless from the raspi all you would need is a power lead coming out of it for the psu. (yes I know a wired connection is better but if its close enough to a router then why not lol).

I have heard that wifi on the RPi3 is merely adequate due to the onboard antenna. Putting the RPi3 inside a grounded metal case would make it worse. Now, if you modded the RPi3 with an external antenna...

So basically it would be a Sidehack S4 but a load better

A few refit boards, atx psu, some nice quiet fans front and back, a raspi and usb hub all inbuilt to one 4U case. Sounds nice and tidy to me Wink

Probably not, given that the boards are flush with the heatsink on 3 edges and the 4th has all the connectors. But the heatsinks do have tapped holes on all 4 edges, so mounting like that is an option for sure. Unless you had custom heatsinks, but then you probably couldn't use all the screw holes if the heatsinks were smaller than the boards and you could get overheating chips from poor contact around the perimeter.

If you took a flat-bottom case you should be able to mount 6 board/heatsinks in there; a bit of drilling will get you holes through which to solidly mount the heatsinks. It wouldn't hurt to put a beam across the top that's notched to stabilize the boards further. You'd probably need to tie into USB headers same as inside an S3 case, and to fit power cords you might need a board built with straight PCIe instead of right-angle, but otherwise there'd be no issue. Tuck a small hub in the corner and call it good.

If you have C1 waterblocks (and there were independent manufacturers building similar things, if I'm remembering right) these would mount right up.

I'm actually curious if an off the shelf water cooling plate or two would be able to be affixed to them.
Hmmm

As for the server rack solution, same kind of solution could be done like with the S1 boards.

I wonder if these boards will be able to be installed into a 4U server case etc.. I realize you would need to source heat sinks, but nothing else would really be needed would it?

You could come up with this kind of solution https://bitcointalk.org/index.php?topic=650462.20
Antminer S1's on a rack.

Saw that. Be more interested in a way to do it off the shelf.
Maybe some cut rails the boards can sit in. Which could then be mounted inside anything. Hmm

The group buy must be talking about per pair. I didn't pay attention to details, as soon as I saw it was advertising stuff I hadn't made yet I figured the whole thing was unnecessary.

I'm basing the 2TH/board estimate off 33 chips per board at about 65GH per chip. Of course that can go up or down, 65GH would just be the nominal setting for the power consumption I'm looking for.

Only the mechanical parts of the S-miners will be reused. Heatsinks, fans, et cetera. The only other parts are the hashboards (obviously not reused) and the controller (obviously not reused) and those won't be reused.

Pretty sure this question has been answered several times (at least once recently), and when you asked a similar question earlier in a GB thread I responded there too.

Hadnt seen it brought up in here? Been following pretty well for a while now..

Quote from: sidehack on December 18, 2016, 01:16:22 PM

If an S3 can fit in a 4U server case then these can also. There was talk about a year, year and a half ago about trying to standardize something like that for more industrial-scale mining with swappable boards. Probably be more fitting discussion for the dev thread than a sales thread though. If I remember, I'll get some measures when I'm at the shop later.

As for bringing it up here. You said this was a betterplace for it.

I bring it up so we can all get a plan to what is needed when these launch.

As for the 4TH statement? The group buy says 4. Not 2... Seen 4 mentioned elsewhere as well.

Thanks

Sidehack, the 4TH boards, what will these use from the old hardware? Mounting case and heat sinks?
I'm just wondering if these boards could be mounted easily in any casing, 4U rack maybe, or PC tower with lots of fans etc. How hard heasinks will b to find

Before someone starts quoting this as a source, AFAIK there is no such thing as a 4Th board, but rather a 2Th board (~200W):

Well, I think I like this idea of a loan concept, Let me give you what I have and good luck. (just got to collate all my BTC's into one account and pass it over to you)

Haven't been on the board in a while and get back to see all the good stuff I've been missing. Shocked

Definitely interested in 2 of the 2Pac for now.

The pod will have to wait for some cash (which might be in time for the Bitfury chipped ones), and hopefully get a S1/2/3 upgrade also.

Headed to the 2pac sales thread now. Grin

Problem I have with them, is they block MAC addresses on their network, unless it's been authorized.
So unless I can somehow trick the system into thinking my miner is a laptop, no joy
But using a USB setup through my already approved laptop. All good

shh...

Your problem is very minor.... *edit* just saw the pun in this one

My Christmas chips from Bitfury have entered the US. Expected delivery Tuesday.

Soooooo excited! I have been anxious for the BF pods.

When they are finally released, I plan to try and build up a proper sized individual solar/battery system for them =) Power outages are rampant in my area. This will help alleviate much of my heartache with my home miners. My internet connection is cellular and already on a similar system.

I've always been giddy about the concept of single devices that could come close to 100w/1Th. Unthinkable not long ago.

I don't think I'll have time this week with a lot of manufacturing going on, but I hope to have a BM1384 pod PCB sent off for by month's end. And then I'll be for the most part in a holding pattern with manufacturing, which will get me a lot of dev and test time in January on BF16 stuff before 2Pac manufacture kicks in.

Luke-Jr was given a 1-chip Compac to develop around. I don't know if the 2Pac will be supported by default (under S5 compatibility) or not.

Evil beware: We have waffles!

Something I will be interested to find out is if BFGminer will work with the 2pac. Per the author BFG is supposed to work with Antminers from the S1 up to the s5. I know its pre-built binaries for Win and 'UX works perfect with the 1-chip Compac with no special switches needed.

Or just run a stratum proxy on the laptop and keep miners on their own switch. There's probably a lot of ways to do that, but it's not really necessary to discuss here.

I don't know if there'll be an update to cgminer proper, that's between vh and ck. VH's code so far compiles cgminer with --enable-gekko like Novak's, but vh's code is better. There is no code "for the chip so it talks to cgminer correctly"; the chip is a fixed hardware implemention so it only knows one way to talk. The code is so cgminer knows how to talk to the chip correctly - or more specifically, chips plural.

For anyone running Novak's cgminer for old Compacs, I'm going to recommend using VH's new cgminer instead because it should do the job better. Novak's was a rehash of U3 Icarus driver (and BM1382 chips), but VH's code is designed a lot more specifically for the BM1384. It'll run even a single-chip Compac more smoothly than Novak's did.

That is exactly what I was trying to assertain

sorry for the lamens wording about the chip talking Cheesy

I'll get a spare raspi sd card to compile the newer cgminer when it's released. Can't wait to be able to see more info such as temp etc on the BW pods.
