Unless you prefer eu based company technobit I can assure all of you that I am having eight chip coincraft board in hand hashing like I beast 240-250 gh And pulling around 3W/GH I believe, albeit overclocked, but without even accounting for the PSU inefficiency. Based on the same chip, AMT are still claiming 0.5-0.75 W/GH at the wall, and thats up from their previous ludicrous claim of 0.25-0.5W/GH. To quote AMTs favorite shill: Yes, I do believe the unit will produce up to 1.2THs, running around 600Watts.

Here are all the addresses I have from HashFast:
Not everything is a conspiracy. This is one is easily explained.

FWIW two cointerra rigs arrived today at my hosting facility and are now hashing away. No tracking number, they just arrived.

A pic of you shaking hands with Ravi, or it didnt happen.

Not every shape can be printed, at least not with my single extruder printer, or not without printing support material which can be a pita to remove. The photo of the object you posted would already be problematic.
These printers work by putting one layer on top of the previous. They can not print "in thin air". You can print overhangs, but not much more than ~45-55 degree. You can also do whats called "bridging", that is printing a short piece in thin air between two supports, but it will sag a bit and the first layers of a bridge usually look rather bad.
That cover you posted, no matter in what orientation I would rotate it, there is always either unsupported overhangs, or some serious bridging, and in places where any sagging probably means it wont fit.
Now the programs we use can generate support material, so that any shape is printable, its a bit like scaffolding, but it will usually take some work with a dremel to clean it up.

I would be interested in some caps for window hardware. The original manufacturer doesn't exist anymore.
What kind of model would you need? Any chance to scan an original part, or so?
Id need a 3D model in STL format (or sketchup or something that can export STL, which is almost any 3D program). Scanning, hmm, .. ive not used one yet, but what Ive seen, I wouldnt expect miracles. If its a complex piece, maybe it would help as a starting point, but someone is going to need to get his hands dirty with a 3D app either way. All that said, Im not entirely sure what you mean by window caps?

Is there a timeframe for this that I missed?

Can we choose the color that the item is printed in?
Just from the ones I listed in the OP. I dont have much color atm, but I did receive some new materials I will be experimenting with once the printer rebuild is complete: - Taulman Nylon. Supposedly even stronger than ABS, and very flexible in thin prints. This can also be colored with textile paint. - SoftPLA. Rubber like material, broken white. - SmartABS. Pretty much like ABS but would be easier to print large objects with. Also white. None of these are tested, and some of them are considerably more expensive, particularly the nylon is somewhat pricey if you need large prints. Coming soonish: - Carbon fiber reinforced PLA. For the record, printer is down for upgrades. Hope to be printing again in a day or two.

Even if they do end up shipping on schedule, I don't think I'd buy from them again unless they offer a really good repeat buyer incentive. Simply because of the terrible customer experience..constantly checking here or on ecointalk to see if there has been a new forum post and nothing.. while Cointerra spoils their customers with high resolution pictures and detailed descriptions on what's going on every week.
Would you rather have a product on time and within promised spec (remains to be seen of course, but still plausible for BA), or a month late and 20% below spec, but with high res pictures along the way?

we’ve delivered on our promise Some balls... Did they hire Inaba?

I see. Well, I'll think about it and try to find out what others are using in this application.... and maybe think of something else, or a design that would look decent at low resolution. Thank you for the explanation. What is the effective resolution? Or the size of the smallest 'bit' that you can extrude at once?
THere is no resolution equivalent in extrusion printing. I can get an accuracy of maybe a few dozen micron, a layer height of less than 100 micron, but the nozzle is 0.4mm wide. That doesnt mean I cant print thinner lines than that, because you can, if the filament is "pulled" in to thinner threads, but it gives you an idea. Id guess that anything smaller than 10-12 pt font is not going to look good at all.

So Nextreme 3 is indeed delayed/DOA. No other reason for this move, and no way eASIC would otherwise give Ken the netlog and IP. I guess thats their way of making up.
Not sure why people consider this good news though; a 55nm asic has most of the disadvantages of a 28nm structured asic (lower powwer effiency, lower performance/mm˛) without having the key advantage: time to market. I guess its about the only thing Ken could do, but good news, it aint.

You are all looking too much into this. A few week ago everyone was saying AMT was a fraud now we are correcting their gamer lol
"Fraud is a deception deliberately practiced in order to secure unfair or unlawful gain " In that sense, yep, they are still frauds. They are deliberately deceiving (prospective) customers.

I can make it, but whether it will be good enough is something else. For this to be useful you need very high resolution, and an extrusion printer is limited in the way it can print "2D". THink of it as writing with a fairly thick pencil: you can make accurate sketches with a thick pencil, but you cant write tiny letters. Especially not if you are not allowed to put down more than one layer of crayon on any piece of paper. Or another way to think of it, can you write the text nicely with one layer of cooked spaghetti? A blocky font might work, or something with an even line width, but frankly, for this application you will want a laser sintering printer. Thats unfortunately hardware thats totally out of a hobbyist price range.

Awesome, It would probably be around 20cm x 20cm x 3-4cm high. I will work on the CAD file, pretty sure I can export Inventor to STL. Any idea of shipping cost to US?
Shipping will likely be ~$10 if its less than 350gr, $15 otherwise (uninsured, no tracking). 20x20 is pretty huge though. Depending how "massive" it will be (infill required). If it becomes a print that takes >12-24 hours to print, I do reserve the right to refuse it. To give you an idea, just download cura: http://software.ultimaker.com/install it with default settings (reprap, 0.4mm nozzle), and import the STL.

Sorry if you mentioned this already, but what do you need to create one of these? A 3D CAD model, dimensioned drawings, etc? I have two things in mind that I would be interested in getting.
One last question, can this material be painted on? I wanted to make a custom cribbage board and then detail it with paint.
I would need a (faultless) STL file, thats a standard 3D format for these things. A sketchup file might be ok too, but no promises, as sketchup stl export is sometimes a bit dodgy.. If you cant use these programs, but you do have drawings and the model isnt too complex, shoot me a pm, we might be able to work something out; unless the design is really trivial, it wont be for free, but Ill do it for a very reasonable sum. As for painting; yes you can. Its recommended you use a (automotive) primer first, then acrylic paints will work fine on both ABS and PLA.

Hello, I am interested!
Specifically up for a Raspberry Pi case.
So I just pick one from Thingverse and you'll sort out the rest? I'm based in the UK btw.
Yep, pick one and choose a material/color. Please pick something original . Ill slice it and give you a material/shipping cost estimate. Could be a few days before I get around printing it though, bit of a backlog, especially if you want ABS. BTW, you can get a timelapse of the print itself. The camera is mounted on the frame, not the moving bed, so unfortunately for most prints the video looks like a blurry mess, but for some types of prints, using one frame per layer it can look awesome. Here is a recent print of some rocket parts: http://www.youtube.com/watch?v=ZIpOr63hTB4Probably wont look very interesting for a typical raspberry case though

Vince says we switched from Nextreme to Easicopy, Puppet says we should do Nextreme with Easicopy happening in parallel for later.
I would like to draw everyone's attention to the following diagram (pay close attention to the first step in purple, as it's a requirement for both approaches):
[...]
As such, the wisest move would probably be to do both, in parallel, but only after checking some samples work (Nextreme).
Nice digging, lucky I caught it in this maelstrom of trolling. Pretty much confirmed what I thought, however, it also strongly suggests my earlier hypothesis is correct: nextreme 3 is not ready. Your links refer to nextreme 2. No reason to assume the flow is any different, even the timing will be pretty much identical, but try to find any information or PR or whatever on Nextreme 3 on easic's site and you will draw a blank. ebeam might only take hours, but if you dont have prefabricated nextreme 3 wafers to apply the ebeam process to, that doesnt help you.

Q. What went wrong with the RTL? A. I didn't get a direct answer with this other than delays were made to make better decisions about what direction the company would take due to competition and bitcoin price.
The difficulty rise was too rapid and manufacturers started offering very efficient 28nm products at $3/GH - Ken realised Nextreme chips were too expensive to manufacture and too inefficient on power. The right decision was to switch to Easicopy, and this is the decision I believe Ken made. I've been saying it for a while now, quote me on it later. If this is the case, people should be extremely impressed with the companies ability to "turn it up", and ken's guts to take this step despite the fallout we're seeing on the forums. You are overlooking one crucial element : timing. Easycopy as I understand is a full mask set process, like any other asic. Tape out process would be pretty much identical too, and therefore if the RTL is only finished just now, and even assuming eASIC has some magic software to synthesize an RTL in to a GDSII by pressing a button, it will be months before that results in actual chips. OTOH, nextreme should in theory allow at least samples in a very short amount of time (especially ebeam samples, but even single mask wafers ought to be lot faster). So even if those chips are less power efficient and (far) more expensive, I doubt it wouldnt be worth it. We are no where near the point yet where asic production cost is an issue. I do agree that Easycopy should be developed in parallel for when that happens, but I see no reason to halt nextreme chips unless for whatever reasons, these cant be manufactured within a short order either. Which would point to eASIC nextreme 3 not being ready.

RasberryPI cases will not be worth it though. You can get them for around 2$ from Aliexpress.
Which is true for all things that are made in large volume. With volumes in the 1000s (never mind millions for rasperry cases) injection moulding is infinitely cheaper (and faster) than 3D printing. The thing with 3D printing is that is can print one off pieces while still being affordable. Perfect for crazy experiments, own designs or things you come across on thingiverse. I mean, can you buy this on Aliexpress? Or.. this?
