Here's a
link
to the video I finally got done. Sorry again for taking so long. I'll talk about that a bit in a minute.
Right now, and you'll need to watch the video to see how the pool setup page is, I have a technical question. How the hell do I set up for solo mining with this beast? I want to take a stab at a couple of SHA-256 alts, for fun, profit, and your viewing pleasure. If possible without taking the thing apart and running the boards individually with Hexminer.
As to how long this is taking, I again apologize. My personal situation is ugly. My wife, as of six hours ago, is hospitalized for probably a week. I have a newborn daughter and a seven year old son, and more stress than I can really deal with. I have been a bit snippy with some people on the forum where I try to be measured. If I stepped on any toes, I'm sorry. Due to the constant medical issues, I have had to take a leave from my job to care for my children and wife. For the moment, this miner is my sole source of income. That's not much. Obviously unsustainable, and I'm working on fixing that ASAP, which leaves me little time for keeping current on this, and little incentive to take it off of Eligius, where it's making me something every couple of days. I do believe I can probably do better by mining alts and trading them, but that's a bit difficult right now.
If the above sounds like whining, I'm not prepared to deny the charge. It's been rough. I'll shut up now. The miner works good, at least
Yesterday, AMT was supposed to start delivering the Coincraft based miners. To my knowledge, no one has received tracking info on that yet. I have been very upbeat about this company, because they were good to me and because I like the machine. But if there are no tracking numbers out in the wild in the next couple of days, I'm going to be very disillusioned. AMT, I know you read this thread. Please come through, here. I want you to succeed. But you told me that you wanted me to be objective, and objectively you're not doing so good. Make it right for you paying customers. Even though some of them have gone off the deep end, it's still the right thing to do.
As an aside on that, AMT's business partners in Switzerland are cutting off their own balls with their continued stalling and silence. Come on, vendors, TALK TO YOUR CUSTOMERS. Even when you fuck up. Even when it's bad news. If they are informed and kept in the loop, most will forgive. You can't please everyone, that's an impossible task. But you can keep most of 'em happy by just being honest and informative. Most of us know that shit happens when you're working with bleeding edge technology. Tell us about that shit happening, and you save yourselves ten pages of FUD, easy.

ok, the thing has now been hashing nearly continuously for a bit over a month, totally reliably as near as I can tell. I'm still working on a video. Lots of personal problems at this end.
The "sweet spot" for voltage appears to be 895mv for me. I've gone up and down from that, and got lower average hashrate both ways. It seems to average 83 GH/s local, and around 81 at the pool.
I hope to make a video detailing all the features that I understand (sceenshots and whatnot) later this evening.
My overall impression remains very good. If the quality of this machine is an indicator, AMT is the real deal. They do need to improve their customer relations, but that is true of just about every ASIC company out there, with the possible exception of Bitmain. I want more of these. And bigger

update From here on out I'm going to put any new news or changes to the top of the page, and put in a reply that says OP updated. For those of you into conspiracy theories, get out them screen grabbers! (I will probably delete and reformat as I go along)
This is just a minor update. I've been running the thing on two pools, primarily Eligius, but briefly on BTCguild. Made better money on Eligius, and I really like Whizkid, so I think it unlikely that I'll do much more if any pool exploration while I only have the one machine.
I've done some playing with the voltages, and I get weird results. If I leave it at 900mv, the setting it was delivered with, it is very steady at just above 80 gh/s. If I up the voltage, I get runs where it approaches 90 GH/s, but it's all over the map. Now the weird part. I've been averaging about 83 GH/s with it set to 890mv. I'll tweak a bit further, but so far undervolting has given me better results than overvolting. The "chip frequency" is set to 540, and I haven't touched it. I don't know what it does. Any insights would be helpful on that. I'm going to try dropping the voltage a bit more next, and see where that leads.
Also, while hashing on the guild, Cgminer kept showing four modules with two disabled. A hard reset (power off) put it back, but reboot didn't. Didn't seem to harm anything, and it didn't do it on Eligius. I don't get that. It has two modules. As I said, it's weird, not traumatic. As far as I could tell, it didn't affect the hashrate in any way, it just looked odd.
Money is tight as hell right now, so I'm not tearing the thing down until after the first week in february. When I do, I'll take pictures of every component and post them up in this thread. I may put it in a different case, as I have a good sized one laying around. Then again, I might not
Ok, guys, here it is.
This is a first impressions post of the AMT 80 GH/s miner. It arrived yesterday (1/7/14) at about 6 pm. I wasn't here, so it remained in the box. I posted a video of the unboxing on youtube. I'll edit this post with the link in a bit.
First impression is the thing is bloody small. Then again, it's not very power hungry, so this doesn't seem to be an issue. It's very nice looking in a plain sort of way. I'm a bit of a minimalist anyway, so that appeals to me.
It has an actual powerswitch on the back of the PSU, instead of a softswitch. This too appeals to me.
Enough of that, Kevin, does it hash?
Well, yes, it does. Jim had sent me an email saying to call him to talk me through setup (which I'm still gonna do, since My bashing didn't learn me everything), but I got that email after midnight so I took a stab at it myself.
Bear in mind that I am a noob in the extreme. I've read a lot about these devices, but this is the first one I've ever seen, let alone used. I had to do some research in how to use putty and the like, but I got in, and I figured out how to set up the built in version of cgminer for Eligius. Got that going just a bit ago, and it's happily hashing away.
Here's a link for that, for tonight at least. I intend to experiment with solo mining alt coins in the near future, but right now I don't know what I'm doing well enough to even attempt it.
http://eligius.st/~wizkid057/newstats/userstats.php/1NAivofNXdKhzPvigtWLWMWxYT64huQ8QIt's hashing around 85 GH/s, so a bit better than advertised. So far my only complaint, and this may not even apply to the units being shipped to real customers, is the lack of documentation. I know very little about linux, so I had to do some searching to figure out how to get into the thing. But I DID do it. The miner works good right out of the box. I suspect that I mined a bit to AMT's account while I was figuring it out, and they're welcome to it.
I'm going to leave it hashing on Eligius for a while, while I sleep at least, and after I talk to the AMT guys and have a better idea what I'm doing, I'll start pushing it's limits. I'll also post video and screenshots for future sessions.
If AMT can deliver these in bulk, I think they are a good entry level miner, and if the big ones work as easily as this one, this is a winning company. They lack polish, but so far I love this machine.
Also, this is a self moderated thread. I'm not into deleting stuff, but if it gets out of hand I will. That being said, I have thick skin and I like to debate, so don't hesitate just because of this. I figured a divergent thread was probably appropriate as things get lost in the noise on the official AMT thread as it is.
Oh, there were some questions asked of me in the other thread.
It is a pair of Technobit HEX16B hashing modules. I haven't popped the case open yet, but I think the on board computer is a raspberry pi. As near as I can tell it's intended to be a standalone unit, but I'm not sure I have it configured properly for that. Not sure I don't either. I'm watching Cgminer in a Putty window. I'll probably shut that down and watch my Eligius page to see if it's still going on it's own in a little bit. I'll update y'all on that.
It runs very quiet. I can hear the fan, but it's not screaming. The case is barely warm to the touch and it's been running for a couple of hours now.
Can't think of anything else right now. Feel free to ask me anything. I'll answer all but the most personal questions as best I can.

EDIT
I think a disclosure is needed in your post. Those that followed the AMT thread will know, but others may not, that you were sent this miner for free by AMT in an attempt to prove their legitimacy. I think its also reasonable to mention that while you received your demo miner, actual paying customers still seem to be waiting for theirs for 6+ weeks now.
Puppet is correct, I was sent this unit to evaluate it. I split this off from the main AMT thread, and failed to note that in this thread. No concealment intended. Just an oversight. As the shipping delays, I don't have any knowledge as to what's going on there. Those that say they can't get hold of AMT puzzle me, as I've yet to have any problem, either by email or phone.
EDIT2: Here's the link to the unboxing video.
