Um in that pic a least one chipsink is very askew. AFAIK they are (should be) epoxied to the chips so odds are that chip has been partly torn loose and will most likely be shorting out... If lucky they used thermal tape vs epoxy. Is the chip(s) still square with the stenciled outline? Still firmly attached?

No.  The heatsinks are attached just by thermal tape.  One of the heat sinks fell off and it is clear that is is thermal tape.
Then at least the chips should be OK.

I wonder if I should remove the chips and have them sent to technobit to assemble devices:

I'd certainly look into it and if possible, have THEM remove the chips from your boards just to minimize chance of you damaging the chips. Just unscrew the boards from the big heatsinks, give a twist to loosen the TC bond and remove them to save size/weight.

Does it have a micro-usb on it? Stand alone Pi's get their power through that. V1 chips use 5v @750ma, v2 chips require 5v @1a.

I am just waiting for someone... anyone... to tell me how to wire together the AMT parts!
Perhaps Opieum2/MrPark can post a few pics of the cabling?

Ja. Saw an early youtube vid from Dec. 23 on unboxing/starting up an Ant S1 and yeesh! The thing had TC all over it like a paste feed line blew off and sprayed it.. At least AMT hasn't done that yet.
6087  Bitcoin / Hardware / Re: New Official AMT Thread on: April 29, 2014, 11:54:05 PM
Just to nit and keep info straight, yes all thermal compound must be removed from where it dunna belong however most thermal compounds including Arctic Silver are not electrically conductive.

They do have a dielectric value (makes fair capacitor material). If in the wrong place it is like tying small value capacitors across leads/traces. That can lead to fun things like unwanted signal coupling between traces/leads, changing clock freqs, etc.

Any silver bearing material is to be used carefully as it WILL attack any aluminum parts it touches and the corrosion from that certainly cause a real short.

very unfortunate situation.  I have a brick that I paid $6,000 to acquire.  still waiting on that missing backplane.  

wary of sending anything back to AMT since they don't seem to be receiving anything nor is there even a chance of getting anything back.
Given the slim chance of help for ya, for now guess it's up to us...
As ISAWHIM said, the backplane can be repaired. After repairing it what needs to be done is find what card caused the overload.

Trouble shooting basics:

With backplane repaired, and inspected for any shorts along where the trace burned:
Remove ALL of the ASIC cards and plug in only the floppy power connector. No GPIO to the backplane yet.
Briefly power up. Any smoke?

If not, power down and GPIO cable time, along that line; Is the GPIO card plugged in right? If the board sockets are not keyed if lucky there is P1 label on the sockets to identify which end of the socket gets the red wire on the ribbon cable. If no label, then standard practice is to have the cable leading straight out from or into the edge of board, not folded over the connector. No guarantee on that.plug the GPIO cable into the backplane and either the RasPi  _OR_ the mainboard that has the 24pin PSU connector on it. Not sure how AMT did it... Opieum, since I don't have a miner just guessing so comment on that?
Dragons look like they use GPIO from a real RasPi to the mainboard and then a cable from main to the backplane.

Briefly power up. Any smoke?

Turn on again and see if you can log into the RasPi.

If you can that only leaves the ASIC cards which will need close inspection around where the backplane plugs in.

The 5v most likely feeds the SPI interface and a data signal level translator for ASICs. Hopefully should not be too hard to see where that 5v rail is being shorted...
6089  Bitcoin / Hardware / Re: New Official AMT Thread on: April 27, 2014, 12:55:50 AM
Plugged my miner is after I got a blackplane from another AMT customer.  Note: AMT has not shipped me a backplane.

This is the result:



The backplane started going up in smoke when I plugged it in.

Notice the burn marks at the top.

No wonder they conveniently forgot to include a backplane.
eep! Would be interesting to know where that trace is fed from as it tales a fair bit of current to do that. Is not from the 2.5v tab regulator as that is self limited to 1A. Don't think the GPIO can supply that either even if backwards. Got a shot of the end of the board to the left of that floppy connector?

Sanitized works for me - just looked over at the other and way too toxic.
And yes them are some pretty messed up rigs due to grossly improper packing posted over there.

Nope. Don't do Facebook. Hate the entire concept of it and refuse to support anything that ass Zuckerberg is associated with.

I know whatcha mean. The lil Atom PC I have for my TV mmedia is the the BTC core host (only takes 20 w) with a 60gb ssd in it. Shocked the hell otta me to see that massive chunk taken! Found out you can relocate the db so moved it to my 12TB NAS bucket. Works perfect.
6094  Bitcoin / Hardware / Re: New Official AMT Thread on: April 25, 2014, 01:46:03 AM
@AMT_miner technical question, what should be the baseline setting to run cgminer at?

Code:
cgminer --lowmem --bitmine-a1-options 16000:800000:8000 
this is the nominal setting. I presume this is the mode it is supposed to hash at?

Also for the Rosewill Hercules 1600W PSU you recommended what is the recommended hookup for those? I want to make sure this is all correct and according to your spec before moving forward. Ideally I would like to be able too get these working according to your recommendation. I will reach out be email as well to get the correct info. Thanks



16000:1000000:8000,  is the bitmine turbo setup so the above will be bitmines setup for nominal yes

but the amt machine runs 16000:750000:4000 as a1 option i believe in nominal and  16000:800000:8000 as turbo.

Josh told me in his office while taking possession of the demo miner, the first two settings are set the same with no difference in output, with the third setting, turbo, being the second. I believe one would have to look at the programming to see if such is the case. Hope that helps, all.
just to clarify what i said the amt miner runs with mode 0/1 16000:750000:4000 (i believe to be the power save and nominal setting in web gui) and mode 2 16000:800000:8000 as the "turbo" setting dunno if altering these settings to the bitmine a1 options of   16000:800000:8000 nominal or 16000:1000000:8000 turbo would make a difference except generate excess heat and blow it up!

my wonder is if you can "solo" mine on the machine or with it. would i need to install a wallet on the kernel sd? if so i wouldnt want to even try. linux is a pain. or could you somehow run byproxy through pc and router like a gateway?

I'd say PM ISAWHIM about the settings. He is/was part of the A1 chip dev thread and should know or point ya to someone from there who does...

On solo mining: DL the full Bitcoin core client onto a small pc with a lot of storage (currently the blockchain db is just under 19GB) and run it in server mode. Point the miner at the PC's ip address and hash away.
Oh, there is a bootstrap file of the blockchain current up to Jan of this year last I looked that reduces the time to get the whole blockchain to 'only' about a day or 2. The feed is purposely throttled to keep you bandwidth usage very low.

 The only other thing to add is that I was able to do a lot more with the broken wallet by connecting the hard drive to another PC. I was able to do that because I run Ubuntu (Linux) which usually will run on any machine it is plugged in to while, if it had been on Windows, I don't think I would have been able to plug it in to another machine. That would have meant I was going to have to ship the laptop off to a factory with the Bitcoin in it or buy another hard drive before I did. Linux is a more secure operating system for Bitcoin than Windows IMO.
As long as the drive is not encrypted Win xx would see the drive just fine aside from maybe having to go into Administrative Tools > Computer Management > Storage to get it recognized. Just don't try to boot from it...

but if they are an "Authorized distributer" shouldn't the same rules apply? If not why?
They may.
But - last time I looked at BM.ch (end of March) they only had pre-order, no 'reservation queue'. Is why most of their customers are in the same boat as those here over refunds. And Toots is right. You can cancel from their new queue only because you had not given BM.ch yer money yet.

AMT,
     Are you going to post any official updates to the status of the 1.2 TH miners? This is the official thread to discuss your hardware.
Agreed. AMT, ya know, something like this update from Black Arrow? http://www.blackarrowsoftware.com/store/bitcoin-miners-progress-update--17-april-2014.html
They too and their customers are in a world of hurt but at least reasons are being given.
6099  Bitcoin / Hardware / Re: New Official AMT Thread on: April 24, 2014, 03:14:22 PM
AMT,

Still waiting for the missing backplane and cable that you promised to ship me a week ago.

It has been 3 weeks now since I got my miner.... it has not been runniing because of missing parts.

Are you going to compensate me for the 3 weeks that I am unable to mine?
It may be an ass-backwards way to get them but have you tried PM'ing Phin to get the parts from his miner? Considering he does not mine, might actually be useful for that.

Well, I pinged Bitmine, and they claim that they are sending me the backplane.  
Faboo! As for the GPIO cable, it is a standard and common item through Amazon, Digikey, etc.
