AMT_Miners: Ya know, your site still advertises the 520 miner as:
Product Description
Plug & Play Bitcoin Miner
520 GH/s nominal performance ( + / – 10% )
Included accessories: USB Cable and Power Cord
Chip: Asic 28nm
Weight: 16 lb.
Dimensions: 10.50 x 12 x 16 high
Warranty: This unit come with a lifetime warranty.
Product specifications may differ from (+/- 10% running variance)
Your order for this miner will ship in 4 weeks or less.
Now considering I ordered at the end of Feb when it said the same time frame, with still no miner and many others far ahead of me in the queue that is blatant false advertising. No 'pre-order' wiggle room there. No mention of 'expected ship date' either. That is a firm statement which you have no ability to fulfill.
I highly suggest that you remove any shipping time frames from ALL your advertising...

Finally got my backplane....
but it was Bitmine who shipped it all the way from Switzerland!
So looks you can bank on Bitmine to 'semi-support' the product.
Still can't test my system because it looks like my raspi got fried.
+1 to Bitmine.ch for that! If that appears to be a real RasPi, think you said you have another around right? Pull the SD card from the dead one and use it in a working Pi. In fact, first use AMT's SD card in your Pi all by itself using 5v power fed through the micro USB - nothing else attached (aside from monitor/keyboard of course) and see what it does. |

I might do the whole technobit thing. That sounds like a viable option. Hopefully not an expensive one. Can you link it? Or PM it to me? I would be interested in going that route. Thanks for the potential solution and contribution  certain poserkos I won't name by name do nothing to contribute help its nice to have people who do contribute solutions  Here is the assembly service for an 8 chip board, 209 EURO: http://technobit.eu/index.php?id_product=67&controller=product&id_lang=1The owner (marto74 ) is in BTT. So we can ask if we can send the AMT boards and they can 'mine' it for parts. Please reach out to marto74 to see if he can accomodate this. THanks I am going to reach out and see what can be done. While it adds more expense at least we have a chance at getting working hardware with documentation and support behind it. And have ya looked at the enlarged pics of the boards layout Technobit is using? Massive more cooling on the chip side vs lil' stick-on chipsinks made easier by the CORRECT cluster placement of the asic's, much better core power VR layout as well not to mention using 2 pcie power connectors per/board vs only 1 (easier to divvy up the PSU outputs). Even are using what appeares to be Bergquist Blue thermal filler putty to suck out all the heat possible from the chip body  http://www.bergquistcompany.com/thermal_materials/gap_filler/gap-filler-3500S35_properties.htmOverall a very superior power/thermal layout. Looks very nice and per 'my spec' iff'n I was to do it. Icing on the cake would be if the board was Tlam vs FR4 fiberglass |

anyone know of a guide to mine solo with the rigs? id like to try a lesser sha coin than mining on cex i hvae the wallets ready is it just the same as solo gup or eruptor mining. open wallet with allow ip 127.0.0.1 port 1234 and just point miner at the same?
You have to set the config file for the wallet you want to mine to, with those settings. thanks i will try this. it didnt work the miner just hangs. no idea how to make the miner seek the work. Have you looked at QT's Help>Command-line options? Huge list of info there. |

Exactly the problem is not with the A1 chip its with the boards designed to run it.
Innosilicon had an agreement with bitmine that bitmine would have exclusive rights for 6 months, either outside of China or globally I don't know the ins and outs, but bitmine dropped the ball on getting their product to market in time because they had the worst designed circuitboards and poorly chosen components and basically didn't know what the hell they were doing. I think AMT also suffered because of this as they were using bitmine designs manufactured in the US.
As the deadline drew close for the exclusivity period to end the Chinese companies like Dragon started producing their own boards, but much better boards because they know what the hell they are doing of course, from what I understand they even helped bitmine by providing them with design and component reccomendations to fix the bitmine board problems. But it was too late. The deadline expired and before bitmine or AMT could even start to look at getting stuff out the door the Chinese started production. Game over.
In the mean time Technobit in Europe managed to produce circuitboards, albeit with less A1 chips on them, that worked in smaller application (up to 240MH) without issue.
Thats my take on whats happened from what I have seen and heard from various sources.
+1 That is pretty much my take on it as well. It seems that Bitmine/AMT took their business planning lessons from the underpants gnomes... Phase 1: Collect Underpants (or make mining ASIC chips) Phase 2: ? Phase 3: Profit |

any recommendation for newbie like me, i mean totally newbie  Go to the root of this Forum and browse from there. This is waaaayyyyy the wrong place to start.  |

a1 chips are they not made by innosilicon? bitmine uses those designs and resells to other groups (like AMT) and what appears to be a few others with similar problems. If I am in error then maybe its off. But my point is the few players out there like cointerra, hashfast and even bitmine are dealing with the same problems. Anyway it looks like its an individual design issue on a per company basis it seems. So I guess it could happen to anyone not well versed in the hardware side of things. That said these other companies with no issues seem to be properly calibrating things to work optimally. And advertising it based on that performance and its gravy if its faster. Right now I have one hashing miner (because one is totally dead in the water now and I swapped out the sole working card to get a full working miner out of it). I am hoping I can somehow revive the other one as I know one card is beyond saving but the other ones might be possible to bring back with the right setup. I feel the aggravation here others are feeling too, I just don't always wear it on my sleeve. I have been getting help from various community members, notably ISAWHIM, with my miner. I wont go into more than that but I have some other things in the works that might make the dead miner come back to life. As those of you with hardware I too have a 6k brick as well. Fortunately I have another one that actually works. I count myself very lucky at this point. But would like some results too. For my part I have been making good faith attempts to work with AMT to address my problems as I could also pass some of that knowledge over to those with similar issues. I might do the whole technobit thing. That sounds like a viable option. Hopefully not an expensive one. Can you link it? Or PM it to me? I would be interested in going that route. Thanks for the potential solution and contribution certain poserkos I won't name by name do nothing to contribute help its nice to have people who do contribute solutions AFAIK the A1 was designed at the behest of Bitmine.ch by Innosilicon. At least in the past, Innosilicon is an OEM chip design house not a chip maker or OEM per-se. Chip production for all A1's is by Global Foundries. Now, who controls the A1 design/production now... unknown. BitMine? Innosilicon? If Innosilicon has any say in it then they have an agreement with BMch unlike any I have ever heard of in the semi biz. Possibly result of contract point failure penalties? |

It's interesting but I see bitmine having alot of the same issues AMT has been having. Altho it seems less so. Refunds issues, delivery issues, all of the same. Like I said....seems like anything/anyone using A1's designs is having a ton of issues. Companies using other chips seem to be ok in terms of delivery. Something worth noting if you are looking for vendors. Just seeing a common thread here with the hardware is all. There is this race for a 28nm process, but at the same time with all the problems, it almost seems like the stable and already mature 55nm process or 40nm chips based solutions are better at this point to go with. They work they are stable....and most of all they are shipping and largely on time.
Realy  My technobit boards A1 are working non stop. And same is happening to other A1 hex8/hex4 technobit clients So do not speak bulshit please. You can always asume that everyone has issues but facts are different Never tried designing a higher density packaged version of those stand-alone boards have ya? Sure the A1 chips can run but making things run in a 1 board setting is entirely different than making a *system* of them work. ALL of the system builders are having the same issues simply because they had not planned on the chip being so off advertised spec when it was finally placed in their hands to do something with. I don't recall the Dragon Systems having trouble? The Technobit boards appear to work. It may be worth the effort to remove the cointcraft A1 chips from those bad AMT boards and sending them over to Technobit to get a new system. Drastic, but what other choice do we have? The only 3 pictures I have of Dragons show an entirely different packaging design than AMT tried. Much like BitMine.ch the Dragons went straight for a full rack design right off the bat though it looks like the Dragons planned even that better 'specially PSU location. |

Right and good luck starting legal proceedings in Europe. The EU or Switzerland it can take years just to look into it. The US in that sense is a much more consumer friendly situation. Basically anyone using the A1 chips appear to be having issues in some area or another.
ja. Personally, worse come to worse I'll see if it can be written off come tax time (if anything, as 'computer equipment') to maybe offset of of the cap gains tax on BTC income. While rather cheesed at this kerfuffle and most likely being out just over $4k, frankly, this past month or so I've lost more from some of my SEP holdings. At least they will eventually rebound though... Already told my FA to stay away from silver  Only taking this view because of the speculative nature of the biz to begin with and so only used a minor part of my xmas bonus on it. Shoulda taken a nice vaca with it instead... |

Ya know folks, Bitmine.ch still lists AMT as the Authorized Distributor for North America. http://bitmine.ch/?page_id=5426 btw, I also have a screenshot of that page for when that changes. As such, they are also legally involved in this mess. While they may have no direct control over how AMT is ran they DO have responsibilities for actions taken by AMT in their name. Just sayin'... One thing interesting that will come out in court is if AMT even ordered/paid for enough chips to cover miner sales... |

Power...if you dont have the space, or power in your home or facility then it makes sense to host it somewhere that can. Thats actually a bargain to host it at that price.
It is if you only have one unit. I just got a full rack at a nearby colocation facility, very secure large data center in Naperville, Illinois for $600/month which includes my first 40 amps of power (after that its metered but at a lower rate than I would pay at home). I could theoretically fit 27 Spondoolies SP10 in there (assuming I could afford 27 of them, which I can't alas). Power draw for 27 SP10's would be about 300 amps .. but my first 40 amps are included so i would only pay metered power for the remaining 260amps.. but considering that hosting 27 SP10s would cost well over $5,000 a month, you can see that a DIY rack in a good data center is still a much better alternative (granted my colocation deal is very good .. next best quote was over $900 so YMMV, but still if you have a lot of units paying a per unit hosting fee is probably never going to be a good deal vs a DIY rack). Hmmm.... Our facility has a good bit of open room upstairs and use only ~200kw of the 500kw feeding the place. Also have a 50kw backup genset. Anyone ever look at what the actual bandwidth of miners are? Might investigate doing a little hosting maybe (not a data center) and frankly the lasers we use here are worth more than a boatload of miners. Of course then again there is the cost of cooling... I'm already going to move my Ant pharm there soon as the bill there is only 7-cents/kwh  Und oww! nasty diff jump... |

How do you turn the pi on? There's no switch.
It turns on when the PSU is turned on. |
|

Hmm. Call me silly but in those pics it appears that one can connect any RasPi (assuming you have the tweaked CGminer from AMT or other software) to the GPIO cable and run the blades. Aside from some power breakouts, what's the purpose of the board the Pi is plugged into? The Pi's GPIO looks to run directly to the ribbon connector on the other board.

Thanks! Searched all over the Forum and found nothing on it.

Spondoolies tech are really nice nice guys. I talk to them often because they are hosting S10s for me starting in a few days in Isreal. Will move to S30s after testing the S10s.
I'm curious, considering it looks like you have to buy the miner(s) why pay $250/month each for hosting? Even my hungry 1.2(ish) TH/s Ant pharm only eats $205/month in electric. |

I am not sure if the A1 is the only game in town. What does spondoolies use? Bitcoin.ch might give you the board print out if you buy enough chips. I would suggest going on your own. I can help you if you need to know anything about importing or doing business in China. I would wait a bit til the prices drop and the hash gets faster, but its good to get a head start. Remember this, do not build a business, build a brand.
The A1 is not the only game. Avalon has a new one and there are several others also. Bitfury (eg Ant's) has improved their line as well. Und - how the hell do ya post an image here??? |
|
|
|
not to mention if you could make your own a1 rigs wouldnt you buy coincraft direct? not resorting to buy something someone else made?
When the A1's came out, aside from hard-core hobbyists that was not an option. Now it is. Personally, I'm sticking with my hungry S1's for now... Last I saw yesterday was just under $400 now. |

"WE" as customers cannot be granted receivership. I believe (not a lawyer) a court appoints that to a qualified and disinterested 3rd Party. Now possibly if some sharp folks - with mucho backing - applied to the court fto be considered for the role, maybe.
Even if only for the general health of the mining rig business I still hope AMT can find a way to recover from this mess caused by pre-orders for equipment that has not even been ran as prototypes before announcing them to the world.
