"Some new equipment" being everything required to work with BGA properly. Balling gear, probably some good IR reflow stations with preheat trays, stuff like that.

Military trained me in 2M on a Pace 2500 in the early 80's. So have a handle on IR reflow and the trays. Have any specific manufacturers and models in mind?
I have 0 experience in BGA. WTF is "Balling gear"? Thought BGA chips had the little balls built into them. Think I've seen (Digikey?) BGA sockets like Intel uses for CPU's.

Just thinking outloud here:
1) If BGA sockets are available,
2) and a board with multiple sockets (say 4+) could be designed,
3) then, in theory, one could purchase a board and a hash chip (Spondoolie) and be up and running,
4) one could then buy additional hash chips and "grow" in hash power as desired.

I get that the sockets would add additional expense to the initial board cost, but would add the flexibility to cover multiple purchasers needs.
Maybe if one bought the sockets in bulk one could drive the cost down a tad.

I don't think you understand. What we intend to do is built it well enough that it won't break or fail, and then sell it such that you can actually turn a profit. If the only way to build it good enough to meet our standards is to make it so expensive it's not worth buying, we'd rather not build it at all. We'd rather not get sales than sell something we don't think is good enough to basically put on a lifetime warranty. If I've built it well enough, it would be the customer's fault it catches on fire - something about cranking it to maximum power, taking off the fan and then stuffing it under a couch cushion.

If I built something like the Dice I'd use a matrix of more manageable chips instead. Unless you wanted to pay me at least $500 a week and sponsor some new equipment for the dev, I ain't messing with Spondoolies chips.

The Avalon nano is easy to improve on, since it was built with their previous-gen chip. I expect them to have a next-gen chip in a month or two that I'll probably take a look at.

Also, the shipping yard is in China so we can't really just drive there. I'd rather have the machinery than the money back, because if I got the money back I'd just spend it on the machinery again and that would probably mean paying the $750 shipping fee again, which ain't gonna happen.

"... some new equipment for the dev,"
Like what equipment?

Ohm's Law sucks sometimes. 100W / .5V = 200A. Hhhhmmmmm, so circuit traces made out of #2 welding cable? LOL, wonderful mental image.

"... - something about cranking it to maximum power, taking off the fan and then stuffing it under a couch cushion."
I would pay good money to be a fly on the wall . . . but only if the user sat on the cushion. LOL

"... and it would be very difficult for me to care less than I already do about scrypt."
ROTFL, I'll think about this off an on all day tomorrow and snicker uncontrollably.

Every international shipment we've done that's >$2499 has been a customs nightmare.
For what little it's worth, my heart goes out to you.

So, Novak and I did some discussing yesterday on priorities.

We have 1200 chips from Bitmain, and between their out-of-stock statement and that they've not addressed the question I've asked three times regarding more chips, I have to assume 1200 chips is all we'll see.

Demand for Compacs seems to be pretty high. We were planning on making about 600 Compacs and 200 Amitas with 200 chips left over for dev on larger boards, but I think what we'll end up doing is make 1000 Compacs and zero Amitas, with 200 chips left over for dev on larger boards.

I've got one thing left to test and Amita hardware would be done; a few steps past that and a 4-chip pod board would be done. A few steps past that and 18- and 30-chip TypeZero boards would be done. I'll probably make prototypes of these things with some of the dev chips, but will not manufacture any batches for sale.

If Bitmain (or Avalon, or BitFury or whoever else with a decent chip) will work with us in the near future, it shouldn't be too difficult to adapt the completed designs to a new chip. So it looks like, for this round at least, we're stopping production with the Compac.

Unless someone wants to put up a quarter million dollars for a full batch of chips, but we probably wouldn't get 'em in hand until October anyway and by then Bitmain, Avalon, Spondoolies and SFARDS will be rolling on better tech.




PC, if you do something like that I'll build boards for you. The BE300 was what got us started on this project in the first place.

Prudent.

1) I believe you'll easily move 800-1000 stickminers globally.
2) I also believe that there is a substantial market for S1 replacements.
3) If it were me, I'd reserve a larger quantity (300-400) for multi-chip dev. As it's a skill set (multi-chip dev) that few others have.
4) Bitmain "promised" to release their new product line in July (I'll share the email if desired, think I already shared that with Novak in a PM), anyway, we're sneaking up on August . . . .
5) Since late May antpool's hash rate has gone from high 50's PH/a to 80+ Ph/s and last time I checked they're the second largest pool.
6) Our contacts in the 3M immersion cooling world have indicated to us that the Spondoolies work well immersed . . . How would they know that, unless it's been tried.
7) Getting a VC to put up 1/4 mill for outdated chips would be a very hard sell even with a brilliant board design.
Cool Getting a VC to fund a competitive startup with an aggressive plan not so much. i.e. a company that designs hash chips, builds boards, and either hashes with those boards and/or sells some.
9) If the big 4 release new chips in Sept and whomever acquiesces to selling you chips, I'm betting you'll have a product in time for Christmas. Not pinging on you, just stuff takes time.

GekkoScience et. al., I can think of no other I would rather have designing/implementing boards, you are always at the fore front of our minds in that regard.

But designing/implementing a board without chip availability is a moot point, regardless of the targeted consumer community.
It boils down to a simple supply chain management problem. A problem that I can imagine has multiple solutions.

I think it's safe to say that the BE300 is a dead horse, and I for one am gonna' quit kicking it.
Having said that, I think it's time to pickup the BE300 style torch and design a new chip.
How that would happen, exactly, I'm clueless, but would jump on the supportt/participation bandwagon in a heartbeat.
Just to be clear, I/We are not a Richie Rich and could not fund a 1/4 mill effort.
But we do have contacts that would consider that sum to be "pocket change".

Used to think the small hobbyist miner was a dying breed. I don't hold that opinion anymore.
I believe, at the latest, when the next block reward reduction happens most if not all the small to medium sized miners will go the way of the dodo. That includes us.
I think this time next year the panorama will be very polarized, the extremely large and the extremely small.
So positioning to manufacture and sell to the small has merit.

"With AM doing what it did.  Would be intresting to see someone take that chip and make it and see if you can get better results.  But I'm sure to get the right's would be a mess with AM and cant really consider them reliable."

We have given thought to purchasing the IP (as licensing is out of the question) for the BE300 (assuming one could find the legally clear IP owner). From what we know, it would be a nightmare with the possibility of actors coming out of the woodwork after the fact demanding compensation. If an entity were to obtain the IP for the BE300, the design would need to be "tweaked" to make it a derivative work (~20%) to stay clear of IP infringement. Likely after that expense(s) it would be cheaper to "start from scratch".

And yeah, I'd like to get my hands on qty 100 BE300's.

They also have not responded to my last two or three inquiries regarding chip availability and/or new-gen chip information. The last email I got from them was 12 days ago with a tracking number.

Relieved to hear you have a miniscule amount of "raw material" to work with, else a lot of your "time, hate, and discontent" would have been for naught.

Have been doing some research on the Avalon4 and the sfards.
Not really impressed with the sfards as I'm not an alt crypto kinda' guy.
Now an Avalon4 remasked and shrunk to 12nm-16nm, hhhhmmmmmm.
Really like the ability to tweak bunches of stuff. Understand that's not so much of the hash chip itself but the ecosystem it lives in.

IMHO, what this community needs is to find a chip designer and get something designed and manufactured in 12nm to 16nm (isn't that what AM started out to be?)

Anyway I promised I'd STFU . . . .

Any word on the chip order?

From three posts and 36 minutes farther up the page:

Also, everyone posting and PMing me about picking up a couple sticks, don't. Sales aren't open yet. We still have no public review or opinion from half the testers.

Welp, i'm sure that gets annoying!

It'll be ready when it's ready. I'm sure when they have news it will be posted. No need for daily inquiries.

1) My last post was on July 09, 2015, 04:17:43 PM (6 days ago).
2) It was a statement not an inquiry and thus required no response.
3) My question was NOT about stickminer availability. RTMFP
4) If sidehack finds me/us annoying he can ban us post haste at his leisure.
5) You are not privy to the back channel communications sidehack/Novak and we have had pertaining to this critical (and might I add brilliant) development effort.
6) By posting in the public forumn versus a PM was complying with his request to NOT be PM'ed about trivial matters (completed product availability).

The question was posted because very recently (yesterday) Bitmain has indicated to us that there are no chips (BM1384's) and S5 hash boards available for sale as they have all been used up making complete S5's (The price of which has risen ~$100 in the last 2 weeks). They are also unwilling to sell broken hash boards. It seems they are even having (creating) issues with supplying warranty based replacements. We have 2 boards that need to be replaced under warranty and they are giving us "the run around".

The above is a "sea change" in attitude with respect to our relationship with Bitmain.
Who in the past has been more than willing to supply us with "raw" components for our immersion cooling endeavors.
I suspect that they are "cleaning out" inventory of their old designs and at the same time gouging the ecosystem due to the lack of mining H/W availability.

Anyway, back to lurking.

Hey sidehack with all the last post, Im a little bit lost  Tongue

What is the road plan?

You will produce stick and S1 upgrade or you change your mind ?

stick ------practice r-box board with BM1384 chips --------- S-1/S-3  with newer chips then BM1384

I think the above is the newer plan.

But also not completely sure.

As it sits right now.

I want 2 sticks, cuz' they're cute and to keep/run for posterity.

Currently have 10 S1's (20 hash boards) that are cold and dark and need to be upgraded to something cost efficient.
The S1's are currently listed for sale on eBay, but the closer this project gets to having a viable S1 replacement/upgrade board the faster I'll pull the listing.
Also have space available on several S(odd) waterblocks in the farm (~5 hash boards).
And will want additional hash boards for 2 phase immersion cooling testing (unknown quantity total, but at least 2 to start with).

If the S(odd) replacement/upgrade boards are BM1384 based or whatever based, that's fine with me, as long as that board runs at or below .5W/GH/s

Also have 3 dead Prisma boards whose hash will need to be replaced with something more reliable.

Have been holding off buying new hardware because of this project, Bitmain has not yet released their new product(s) whatever that may be, and Bitmain has no available S5 hash boards and controllers for sale.
All things being equal, I would prefer to purchase from GekkoScience as their designs are typically superior, thoroughly tested, obsolescence resistant, and as such represent a better "bang for the buck".

We need to be buying H/W, ideally something that is physically compatible with the Bitmain S(odd) product line.

Ain't phishing for a deal, just stating what our business needs to do to continue growing and remain profitable.

Hey CG, Wassssuuupppp!

You wouldn't, per chance, know who AM sourced those heatsinks from?

If one were to TIG the sinks together and TIG a cap/tank on each end with an appropriately sized piece of AL square tube stock down the center. . . .
Will post pics when finished.

Any word/rumors on FriedCat's whereabouts?

Sorry, I don't have any knowledge of where AM was sourcing the heatsinks and haven't heard from Friedcat since last year.
I imagine if you weld 4 heatsinks together, you could have a pretty solid short range potato cannon, which should hold you over while sidehack works on the boards.

LOL!!

Well the 4th of July is on the horizon.

hhhhmmmmmm.

A liquid cooled potato cannon. Interesting concept. Now if I can just get DARPA funding . . . .

Too put a fine point to it, I'd like to see: One thousand, additional, profitable, 50TH mining farms in one thousand homes.
Howsoever the H/W is implemented.

During the time I've been involved with BTC ecosystem I've witnessed a paradigm shift in mining concentration.
When one of the "Big 4" operates the second largest pool, and pools that were huge now account for a small fractional part of the total network hash, I get really concerned.

What I meant about costs regarding patents is, if the budget for the project so far has been about $600 I don't think we're gonna be able to scrape together however many thousands of dollars it takes to file a patent claim. I'm also sorta allergic to BS, and every patent I've ever [tried to] read makes almost no sense because any technical information is completely obscured in stupid legal language. I mean if someone wants to go through what I put together, decide if it's patentable, translate the technical information into Vogon and push it through the system pro-bono, sure we can patent some of the TypeZero stuff. But right now I'm a little more concerned with being one of two engineers in a two-man business than being a paperpusher. You may be right about everything, but that doesn't change the fact that I'm broke and undertrained in legal documentation.

Also, and no offense to PlanetCrypto because I know he really likes liquid cooling, but I really don't care much about it. There's just something reliably low-tech about a heatsink and fan that makes things so much easier for regular people to work with, and since making things regular people want to work with is our priority, I'll stick to considering those needs. That said, if our Spec1 boards are compatible with S[odd] heatsinks, it also means they're compatible with the waterblocks folks are using for them, so there you go. The Spec2 board would be built dimensionally as a Prisma board, which I know PanetCrypto has worked with in immersion cooling attempts. Something like that might be better for an oiltank. If y'all want to figure out the best ways to high-density or watercool the works-with-aircooling boards I want to make, I won't get in the way. But I'm not going to retool designs for MinerEdge-style boxes unless someone wants to specifically commission that project and pay for the dev. The miners I want to make are for people, not corporations.

Also, no progress. Family reunions all weekend. Hopefully I have PCBs in the mailbox on Monday though - barebones 18-boards and version 0.5 Compacs.

Regarding patents and patenting:
We're more alike than you might think. I stayed an E-5 in the Navy precisely because I loved the tech versus the paperwork (Was THE senior E-5 in the Navy for almost a decade till I got caught and was forced to advance or get busted to an E-4.)

For some types of patents the process has become much simpler and dramatically cheaper. As is evidenced by http://www.legalzoom.com/sem/ip/patent/patent-lb.html?kid=07705699-061f-2529-72f2-00004a8dcce3&cvokid=07705699-061f-2529-72f2-00004a8dcce3&keyword=legalzoom%20provisional%20patent&matchtype=broad&cvosrc=ppc.google.legalzoom%20provisional%20patent&gclid=COLYl-qWxcUCFQ4yaQodDIIA_w

Jesus, look at that URL. Anyway.
Depending on your upcoming design(s), we would entertain taking on the patenting process BS and is something we can converse about when the time is ripe.

Regarding non-air cooling:
None taken. But let's see if I can make a case for a liquid cooled design for the masses. Air is a REALLY low density liquid. As such, there is a finite limit on how much cooling can be packed into consumer product. That limits profitability of an air cooled consumer design. Which makes them less profitable than an "industrial" design. Traditionally, liquid cooling adds several levels of complexity and failure points, most notably the mechanism to pump fluid. Now if one could design a liquid cooling system that used convection to move the fluid. . . .  This also solves the noise issues that plague a home design that can largely be ignored in a DC. And while pumps have a lower MTBF, fans fail too. And then there's the KISS principle.

Standardization is what made the small block Chevy engines/transmissions, Ford Model A, and Ford 9N/2N/8N tractors advanceable and popular designs. Combined with their affordability. If I were designing something, anything, I'd lean towards something that had become the "defacto standard". In the Bitcoin mining H/W world, I think, hands down, the S1/S3/C1/S5/S? boards physical dimensions account for the majority of the hashing power out there. I think I'd steer clear of a Prisma physical dimensions design and focus on packing the largest amount of hashing power into a board that "bolts up" to a S1/S3/C1/S5/S? cooling device. Be it air, waterblock, or immersion. If it had an edge card connector that plugged into a server PSU all the better, poke poke.  Grin

I contend that if you put that much hashing power on a board that meets those physical dimensions (or Prisma dimensionality) that it will no longer be able to be cooled by air without ridiculously massive heatsinks.

The Prisma design is nicely dense, but is finicky with regard to heat. Due to the huge surface area required "on air" to keep them from burning up (here I'm referring to the cooling not a flawed circuit card design). Friedcat's design to "tube" the heatsinks was brilliant but required from a heat dissipation standpoint (and that required a "one off" heatsink design). Hash chip (BE200) temperature from the front to back vary enormously. The last chain of chips on each board in a properly operating Prisma have got to be on the edge of max Tj. I'm surprised they survive. Waterblock and immersion cooling solves this issue.

IMHO, to keep the consumer/home hasher "in the game" of BTC mining (as this strengthens the BTC ecosystem) they need the kind of industrial strength high density hashing power that large farms can afford to implement. In effect what I'm talking about is miniaturizing a mining farm into a desktop unit from a W/GH/s standpoint. Superior high density board designs (efficient and flexible) are a component of this solution, but, pretty sure you can't do that "on air". Cuz' if one could, the "big boys" would be doing it. Haven't ever heard of a large mining concern that doesn't have a facilities chilled water system, for a reason. This becomes all the more important because home hashers typically buy electricity at a premium price (residential rates).

These small scale mining issues will become more, not less, pronounced as transistor size decreases and eventually bumps into the quantum wall at or below 12nm (Dec 2015 - Feb 2016 ?). The "big guys" will be able to afford and manage those high density designs because they cool with a denser liquid that is enabled by economies of scale. Something the home hasher, currently, can't afford to do.

Am reasonably confident that if you'all produce a high density design that has a common dimensionality (S1/S3/C1/S5/S?) and it can't be cooled by air (in a reasonable volume), this community will figure out a plethora of ways to cool it. Like yourselves, there are some pretty bright bulbs in this box. And am not saying, by any stretch, that I'm included in that box.

First step is to get a board to work with because it's obvious that the "big 4" don't give a F@#$ about us little guys. Little being defined as sub 500TH/s mining operations.

Another key element in securing the survivability of the "little guy" is a source of state of the art hashing chips. Because a board design can only be as good as the components on the board. AM could have been this if they hadn't imploded. And why I'm REALLY interested in who owns the IP for the BE300. But those are topics for other posts in other threads.

As I understand it, Novec Fluids are chemical cousins to 3M's Fire Suppression fluids used in Data Centers.
It's like a "thicker" fluorocarbon freon.
I've personally had my hands in tanks of it and I'm not growing any third arms or heads.
And while it wouldn't be my first choice in a beverage I'm pretty sure it won't kill ya' if ingested in small quantities.
It does not get shipped as a hazardous, toxic, or flammable item.
Pretty sure even the US postal system will take it.

7000, 7100, 7200; when a small quantity is poured into your cupped hand evaporates in seconds.
We use it around the shop as a circuit board cleaner.
But at ~$300/gallon it gets used sparingly.

The MSDS sheet is on the 3M website if really curious.

And it's not nearly as slimy as mineral oil, yuccchhhhh.

Given your quality power breakout boards. I can see this as a big plus in your stable and will help out all I can. The biggest problem with mining as everyone knows is ROI and the cost of running and the heat. A really good idea would to make cooling a big priority. I would like to liquid cool my stuff. just makes it simpler to mineral oil submerge everything and pump the oil through a fan cooled panel like a old cars ac condenser. another idea is make a master backplane for data that you could plug in set amounts of the miner cards so scaling can be dine like the old 10gig miners.

Some stuff we did with immersion cooling.

I didn't really reverse-engineer much. Most of it was just common sense, though I did look at their board a bit to figure out the inter-node level shifters (and I think I improved on some parts of that just a little bit).

I've standardized a design/interface? Which part?

If by "record time" you mean "over a month behind the initial timeline", then yes.

I think trying to patent anything we come up with will probably cost more than, basically, the whole rest of the project. I'm not sure tuning code is actually a patentable idea, since it's been done before on other hardware. I dunno, I think you're complimenting our efforts too highly - but maybe that's because I'm pretty disappointed so far.

"Most of it was just common sense, ..." For you'all easy-peasy, for the majority not so much.

"I've standardized a design/interface?" chip chain design and USB interface.

"If by "record time" you mean "over a month behind the initial timeline", then yes." Apply the 80/20 rule. 80% gets accomplished in 20% of the time allotted, the remaining 20% of the work takes 80% of the time.
Or stated another way, figure out how long you think it's going to take (in hours, days, months, etc), double the number and increment to the next time measurement metric. So something I think will take 2 hours really takes 4 days.  Grin

Using the later estimation method, I'd say you're way ahead of schedule.

For my own projects I always add on an additional 10%. I lovingly call that additional time my "fudge factor". I include it to compensate for all the unknowns that can't be budgeted for. Like staff being called away for family emergencies (family first, rightfully so), supply chain delays, natural disasters, and a million other things that can't be anticipated. Project management is a combination of math and art. It's not a precise science, it's a fuzzy science.

Patent protection doesn't protect what you've spent. Patent protection protects what a thing/idea is worth. It protects future value. It's a time constrained value estimation.
"I'm not sure tuning code is actually a patentable idea, since it's been done before on other hardware." But likely not the way you're going to do it, on the H/W you're working with. That makes it distinctive, and hence patentable. And probably worth protecting. Even if you only improve how it was done in the past, that improvement is patentable, and again, I believe, worth protecting. You deserve to be paid equitably for your effort, because it's not something everyone else can do.

Now I'm gonna' shut up, quit distracting you, and let you get on with your day.  Grin

Given your quality power breakout boards. I can see this as a big plus in your stable and will help out all I can. The biggest problem with mining as everyone knows is ROI and the cost of running and the heat. A really good idea would to make cooling a big priority. I would like to liquid cool my stuff. just makes it simpler to mineral oil submerge everything and pump the oil through a fan cooled panel like a old cars ac condenser. another idea is make a master backplane for data that you could plug in set amounts of the miner cards so scaling can be dine like the old 10gig miners.

Some stuff we did with immersion cooling.
