sidehack, what do you thing a peltier would do? 22 watts of cooling capacity. cool the power section and chip. I would need frost precautions etc but I can do that easy.
stupid? oh yeah that has vapourminer written all over it. I mean anything worth doing is worth overdoing as the saying goes.
ive only known +50W peltiers to go below 0 degrees Celsius, i've been playing with a 40mmx40mm, that runs at 15v 7A for best results, cant get it lower then 7 degrees lower then ambient, off a sink.. |

As stated earlier...
you did? oh bugger me, I'm half reading things again!

What about using some of the high end thermal pads with slight adhesion- I know the Phobya has some thermal pads that are in the 7 W/mK and the lower end Phobya is 5 W/mK. I have never tried thermal pads with ASICS but it cannot be as bad as some of the manufacturers using a gallon of thermal compound. I ask because it would alleviate the need for cooler mounting holes.
well, sticking a CPU cooler to the chips would make a lot of strain, and having the mounds holds them tight to the heat source. if anything, large 3cmx3cmx3mm copper shim would do better.. but the Freezer 7 pro looks to have plenty of contact area. and I thought the W/mK was meant to be higher number is better? Nope. Wrong! http://www.ccfltd.co.uk/Trade-Support/Calculating_U_ValuesThe lower the conductivity, the more thermally efficient a material is. |

Also, I should mention we're looking to use a temp sensor that sits a few thousandths shorter than the ASICs, and park it right in the center of them, so it should make fair contact with the heatsink and get a decent measure of that temperature instead of, say, the temperature of the opposite side of the PCB.
got a layout for these chips? they going look like a 3x3? since they are 8mm by 8mm, thats a 24mm by 24mm, less any space between the chips, so give it 2mm between them 26mm by 26mm, so I don't think them stock Intel sinks would work, I can't find one atm to measure. I'm happy with throwing a "NoFan Icepipe" on that little beast anyway  |

Hmm, the one thing that CK's Solo pool needs is a API for that site to contact and get data off, there is no public API that I can see with the pool, and im not sure if Con would want to go that far as to add that in. A list of workers linked to that address with each ones info would be all you need, Con could add that in, depending on which one is less resource chewing, if any.. CK, any advice? |

When I first asked about BM1384 they offered me U3 I could pull chips off, but I had to correct the CSR who erroneously believed the U3 had those chips on it. A Bitmain rep also sent me a copy of an NDA, to which I responded with a few questions to clarify a section or two, and I never heard back. If they want some NDA going down before they'll work with me any more, they need to tell me and they need to answer my questions regarding said NDA satisfactorily before I'll sign it.
communication breakdown on their side, some how I'm not surprised, with their size and activity. you did attempt to communicate with them again? |

What about auctioning it. People get crazy bidding for stuff that is unique. I would start off the bidding at .35 BTC (if it becomes an option)
One could potential get more out of a raffle over auction, look at a raffle at a fate, each ticket is worth $5, and its for $50 of meat for a BBQ, but the people running the raffle could end up with thousands. where as people will only bid on an item upto the cost they are willing to obtain the item, so the $50 of meat could only go for $75. |

Well ajrgale I got back to write my answer. Seems like a lot of people have given answers that are pretty close to what I have to say.
Yeah, reading it over.. we are maxed at 30 at this time. we have 29 right now with 2 not mining so we have 3 empty spots.
all members have at least 1 stick check
we have more then 3th check
we are a rare pool that you don't lose all your shares if you stop during the 30 day run. Part A ends after 1 day Part B just dilutes check
we allow you the miner a minimum of 1 stick check
we allow you the miner no max hash as high as you want check
I understand this. I went away from sticks only 1 with a max of 50 because 50 x 10gh or 50 x 8gh or 50 x 18gh are all too small to let us ever really hit a block.
no comprehension, other then sticks only doesn't give best hashes, fare enough there, donate a PH or 2,
This setup allows you to mine 1 stick 24/7/30 . It costs you at 20-30 cents a kwatt for a month = 2 to 3 usd per month if you use a rasp pi, plus 25 usd for the stick or 28 bucks. If you do this for 3 months = 25 + 9 = 34 bucks if we hit you get .4 btc at worst.
I don't care about running costs, its going to be parasitic to the other miners of mine anyway. we are doing 3.75th average this is about a 10 percent chance for a block if you do it 90 days.
mean time calculation? so 900 days there is 75% chance give or take difficulty.. The goal is to get a 1385 chip miner in the 600 to 1000gh size that does .20watts or less.
The goal is to get 25th -50th in the club.
This is more viable way for a small miner to mine then any other method available.
If we can get to this good if not also good. At least we tried a way to keep home mining around in an affordable manner.
long term goals for the club. but, its all based on shares yes? so if i throw 1PH/s at the pool I basically get most of the winnings, like a normal PPS pool (if i wasn't donating to it) As I said, the way i though it was going to run, was if we all sign up, throw our names in the hat with what we can hash, if we get a block, 25BTC/stick, who cares what hashing work people put in, if you have a stick, its a ticket into the pool. but im not telling you to run it that way, no no! I was wondering how it is run, it seems to be a monthly run, with so many seats, if a block in that time, reward divided by shares less donations.
It has been discussed on previous page but I know it can be tedious to keep track, especially one guy.
It's true more people have a better chance but like notlist3d said the more people the less of a reward.
Kinda like winning the lottery and have 20 winners sharing the pot. More hash can be donated to push
the chances but as far as a club currently I think it has been discussed by phil to keep it low for now.
As these projects of sidehacks take off the club I'm sure will grow and more will help in tending to the club
needs.
One thing, and it has been mentioned before, is to have multiple teams mining the same pool but differentiated by team names or numbers. Not sharing the pot if your team wins.
i was basically wondering how the pot was divvied up. as mentioned, it looks to be per share.
Personally, I haven't properly considered the number of members. I assume there must be a cap, but I haven't considered the Pros and Cons for the community as it relates to the number. I was pretty lazy regarding the whole thing. I have said immense praise and thanks to our man Phil who is doing more than a fair bit of moving names, numbers, and keep people informed, thanks again bud. I literally setup my sticks to hash on the stick pool and have been playing with one of them seeing how high I can push it (375 was stable. Voltage max and Y cable in a hub which puts out high amperage), but in general I have been lazy about the pool. I should be more involved though, and I've always enjoyed your banter with sidehack and would appreciate your thoughts.
Phil has always done a lot for this community I did see some ideas thrown around in the other thread and since I have not put a fair amount of thought into the direction the pool should take, bare with me as I struggle through something with you.
I am going to leave the member cap alone for now, but will circle back around.
The concept is fantastic. Requiring one particular model of miner and allowing a separate worker with 'other' hash covers the best of both worlds. You have the mainstay of the compac which should and has been dominating the posts in the thread. Sharing information with Peers who may have much more experience, or sharing what you know and maybe help someone. I think it may even be something which inspires more interaction between specific people who are even more like-minded regarding other topics.
I participated in the groups of sorts. I'm sure you have seen folding @ home or the SETI project. Some fantastic groups of people can choose to have their own team so to speak and it may cause situations where it inspires some great values and interaction.
It may inspire a little healthy competition as well. Which is again great for a group. I'm not saying we are there yet, but maybe.
I think any mining machine can take advantage of the same system. For example, start a group of S3s solo mining, or make it an SP20 club and reward for best underclock. Make it somewhere you know a group of people who not only own the same miner, you can try out things and have people who are definitely interested be involved, make replies, share great information, and it gets better over time, but quickly.
Circling back around as I promised to do...
It obviously cannot be 500 people in 1 single group, but that doesn't mean that if there is a large interest of people who want to be in, that something couldn't be worked out. I think Phil is trying to be reasonable yet still keep it at a decent wow amount IF the pool hits.
There could always be second or third groups and that would invite some competition that way, and a little trash talk with the comradery.
I look forward to hearing yours and almost anyone else's opinion of how you grow the size but maintain the scale at something which could grow to be 90% socially dependant. i would also appreciate comments on the donation of additional hash which is not a compac, or GekkoScience product in many cases. Obviously that would consist of additional compac's at this point, but maybe ol' type zero may come around.
The possibilities and positive things which may grow could be great and I look forward to being more involved where possible.
Yes, I was half tempted to set up something like this myself, with the compacs, I talked to my boss to see if there was a way to setup a "solo-pool" using Cons software, with the infrastructure here, it wasn't feasible, then I spotted this one. i can see "this only miner pool" sprouting up, maybe I might just play with a U3 only pool.. I think OgNasty had his pool running seats and 1Oz silver tokens for auction every year/quater/months (one of them?) which is almost the same, a private pool with so many slots. so the concepts of set seats to a pool doesn't bother me, its basically based on what one can support.
I think at a certain point it get's to be unfun to try. It's lotto so the difference between 30 and 50 people is not going to make a huge difference on us hitting lotto. Are you wanting to join the group AJR? Or just making these suggestions?
But Phil had a pretty good setup of it being split part on no of people, and other part based on hash as so many have different amounts of sticks.
when I get my sticks yes, I'll join in. And no I'm not making suggestions, only questioning to what I know and observed. And back to Phil. Have you got a system that collates the hashes/users/donation properly? do you want to see if I can get someone to make a little website that shows everyones details and calculates a final winning output per person? i think Con has a decent plain text output that could pull info off. |

They can always go back and make more chips. I could be wrong but they are making the antminer router with older chips I think. So they have access to chips. It's just they are hard to work with on buying chips.
Also with it being a controller for U3. I imagine they will try to sell them aswell. But I could be wrong.
yes, and if they have a constant foundry running, no problem, but they make say 10K chips, thats about half a silicon bullion, at minimal failures. if they are using a 3rd party top make the chips, they will have to wait in line for the next person to finalise their product. If they are doing it themselves, they will have to retool back to the BM1384 over the xx85. that takes time, and if they are doing it themselves, they would focus on the lithographs they have installed now, instead of realigning the old ones. Also, are they not using a smaller lithograph for the 85 over the 84? As for the R1 as a controller for the U3 (or any other usb based miners) isn't it just a simple Atheros SoC, 64MB ram, 16MB flash. (no idea, never seen specs) with 2x usb off the SoC, and GPIO to the ASIC (probably a BM1384).. i could make my old WRT54GS into one of these, with a compac and have USB out to control a U3, enough room for a usb hub, power and a stick with a nice fan, running openWRT with Lukes or Cons software. |

Bit of updated info. I have a fully-custom 4-chip test board currently running below an S5 controller because it's the only thing I have with BM1384 multi-chip code. Novak's got me a schematic for the entire controls, including volt setting and temperature monitoring. I reckon tomorrow he intends to work on multi-chip code of our own. I'll be out all day tomorrow but when I get back I'm gonna get back to the PCB layout. I have an assortment of schematics on hand which cover node-level parts, the power system, and all the controls so all I have to do is put it all together on one board. My goal is to be ordering a few sample PCBs by Friday.
If everything works, I'll probably make a few so we can run a few for testing and I might raffle off one of them as a way of building interest and resources for the project as a whole.
I'm all in for a Raffle! I'm just trying to thing how one can accomplish this on here, these forums don't have a raffle ticket system, hey? |

What am I missing here? the club has only x spots open, first come, first serve, for only a month? I can understand you can only take care of so many people.
I thought the original idea was everyone runs the sticks with the solo, if block, even split between the total people running sticks (no share counting), so if there is 50 people running 200 sticks the 50 people get 0.5BTC each which would pay back most people sticks (if all 50 people had 4 sticks each, they would profit with 0.1btc)

Bitmain is unlikely to offer any chips I presume until their U3 is dicontinued. I feel it died at launch due to batch orders instead of single units but thats due to shipping costs.
Hopefully we hear about some chips by xmas, that would make my day.
They seem to keep the U series alive though. So most likely one day when U3 is discontinued a U4 will be released. Now that they released a ant router that controls U3's I think they will eventually have a U4 that plugs into it. But I still would rather have one from sidehack, so I hope BM changes mind. I thought they were attempting to dump the U3 v1 and v2? since they made more then they know what to do with, then revised it, without fixing the original stability issue, (also using the old bm1382) no one really wants them. Being at the cost of $60-150 to buy one of them units, doesn't help. When sidehack asked for some chips off BM, they offered him the U3s for the chips instead! On that note, if side just used the U3 chips for the compacs, it would of just been a U2 clone. Now I can understand if they have run out of BM1384 stock, and there is no BM1385 available in stock to sell to the public since they are all been placed on the S7. Following what I mentioned before, throwing paranoia at this and not knowing what was/is in BMs NDA, are they refusing since the NDA may of stated "you must not show how you use these chips" and sidehack has shown Dev side of things with 2nd hand chips? ignoring the fact they do have the documentation on them chips out in the public. ..or is the NDA just to cover how and where one receives the chips (which may state that one is required to sacrifice a goat over the couriers van)? back to reality, we just have to wait it out, for sidehack to setup shop to take in dead/damaged/useless S5 boards or BM to start selling off BM1485 to everyone. |

I had some issues with the second node's reset that took me until after lunch to figure out, but when it lit up I immediately did several pelvic thrusts and then ran into the office to excitedly request multiple high fives. Why wouldn't I want to share stuff that exciting with you guys?
I'd consider pushing this thing to 300MHz/66GH and see how much it beat the U3 by at its own hashrate, but the chips aren't heatsinked well enough. We'll have to wait until I have a better setup.
The highlighted is part of why I love your products, and I am a am a fan and buyer of them. Look at lot of the companies to see what your sharing they would want NDA and sue the crap out of you for releasing it. I honestly am not a fan of NDA's. But it is great how you share dev process with us. I get to see awesome product development and see it along it's way to market, without signing my life away. could be the reason bitmain doesn't want to sell anymore chips, "Cant show 'tem peeps how ya make stuff 'n' things!" and since its all 2nd hand stuff, cant NDA it! but hey, here's some PDF's to show what the pin-out is, and how to talk to it and how to power it, but you cant show them hoe you make a miner with them! |
|
|
|
I wouldn't advise anyone to pay down on a batch of chips without verifying samples first, no matter who makes 'em. If nothing else it also gets you a head start on dev.
Its mean main business with any other IC manufacturer, want 10 chips of the latest Arm CPUs? call them, they'll send you a sample! (i could be lying it could be all distros doing) Hell, even going though distributors, they happily send you samples. But hey, tell that to these head honchos .. |

...
I know some stuff that I can't talk about neener neener but I don't know enough yet to actually do anything about it.
...
Oh he's good at that, about a year ago I have gotten info out of him and told me to Shush about it. I have respect for him because of that, and what he did for people back then, I haven't followed much of what happen this year though.. none the less, I'm not going to throw him under the bus, I still see him as a good guy Guy. Just to have some more options to play with, I won't give up Bitmain or InnoSilicon about chips either.
I should probably go to a bitcoin conference one of these days. Not like I haven't been immersing myself in the community and economy for over two years now or anything, just never had the budget to take time off and go to wherever those things happen. If I make any kind of decent miner I should prioritize it though.
Any luck with them 2? PlanetCrypto is/was looking into InnoSilicon yes? |
|
|
|
I must ask Side, how's the talks with Guy going/went?
I have a feeling he would love to tell us all a bunch on this subject. But I suspect there is a big NDA stopping him. And if you have read any of these NDA's from asic companies it stops A LOT of information from going out. So I understand if we don't hear about this for a bit. But I would be pumped if he does say he got a chip source. he could go "not sayn' a thing" for things are going swimmingly, or "nup, not going there" if things fallen out. you know, the same way everyone else uses the "I cannot comment at this time" when they meant to say yes. but hey, could take the silents as they are still talking |

If he really shipped all of the boards he ends up pulling to you for scrapping the gold-silver then double-bag them in wall mart sacks and put them in duffel bags.
By the time they get to you, they will be already ground in powder from being kicked, thrown, and beaten dust by the shipping company.
you know, that'll make my life easer, I'd ball-mill them then wash the glass/epoxy away, leaving the metals behind.. Welp, the moment you say "go", i'll start hunting borked s5 boards  ... why is ebay aus so barren with any miner (anyone for a U3 for $115 excluding post?)? you'd half expect there would be some on there now.. so it'll be worth me getting some dead S5's and shipping it to side.. 2xS5's +$25 nice deal make that 1 S5 for 1 pod.. but I has 4x non-communicating NRB, can i haz 1?  I'll endeavor to find some BM1384's or S5 boards to trade, that should help the project more |
|
|
|
I'm all in for trading, you can have $50 and all my NRB boards, also if you want, cases and sinks too. but they are all dead, thanks to plugging the usb into a laptop, when the box is connected to a PSU, or vice-versa. (floating earth to grounded earth).. i just want my 400Ghs back  but be prepared to gather a lot of junk if you want to head this path. hell, i might buy the depopulated boards off you, for gold/silver scrapping :-? (shipping gonna be a killer though) |

AJR - what makes it bizarre is this chip takes direct output feedback and a divided reference rather than an internal reference and divided feedback like almost every other buck IC. The 2V reference is internally generated and I use a resistor divider including the pot to feed it into the error amplifier's reference input on the IC. Nothing else touches that part of the circuit, so I don't know what's causing the IC to put out 2.77V on the 2.0V reference. I assumed the buck chip was hosed but the second one I put on behaved exactly the same way, which means something that doesn't touch that subcircuit is either touching that subcircuit when it's not supposed to or is causing the IC to freak out from somewhere else with the reference screwup as a weird side-effect.
I would say check the pot and resistor, pop the buck off and test the pad(s) that dives that reference, if its direct grounded( 0 Ohms) or higher then normal ohms, that may be the issue. now how's the CP2012? is it hot to the touch? that could be throwing the voltage input off, if its shorted dead. anyone inrtrested or having issue with getting BFG 5.3 to work i had to use this bfgminer -S all -o stratum+tcp://stratum.mining.eligius.st:3334 -u your BTC -p x --set compac:clock=0x0782 with these driver http://www.silabs.com/products/mcu/Pages/USBtoUARTBridgeVCPDrivers.aspxThey work fine with windows 10 , I m trying to get to it work with minera with BFG 5.3 as the main BFG miner now not using the custom folder in minera  . never played with minera, but if BFG works with win10 and eligius pool, yes? but it cannot do it on CK's solo? should be as simple as bfgminer -o http://pool:port -u username -p password so bfgminer -o stratum+tcp://solo.ckpool.org:3333 -u 1JiWuyX94wrCr7JhkAn7x5qNMCEef1KhqX.toptekstick -p x |

Thanks for the solo pool change, more data is always welcomed! I'm sure it wasn't done only to support this club, but it's a good feature and I think we'll see more groups like this make use of it.
You're welcome. However I did make the changes purely for this club and hope it means more clubs like this in the future. I could see an s-3 club during the winter. Logic is s-3's are very good space heater if you need a space heater. 50 s-3's = 20 - 25th . run for nov dec jan feb mar pretty good shot at a block i would so love even 5xS3's... but mining at them months? its already 30 degrees'ish now and its only going to climb... oh wait, you're one of them other-side-of-the-worlders ain't ya? Then again, his sticks could have got a 65 million (and it looks like it may not have reset on the last block?)
But it should have reset when the last solo block was solved. I wasn't questioning the ability of a stick to get that share, I was wondering why his worker could report a better best share than the parent address. I could see an s-3 club during the winter.
I would totally point my S-3 at a club address for the winter! I'm just waiting for it to cool down, no sign of that yet in my part of the world... I know it working right i have it setting right here for now http://eligius(snip) I think you want the gekko stick support thread, this one is for the solo club that uses ck's solo pool. I'm a ware of that . Lke i said im trying to Join the club DOES BFG work with the CLUB if not then i wil use CG ? . I gues i should have asked sigh. sense thse is a pool issue not a stick miner issue were else would i ask ?. i don't see why CK's solo wouldn't run with BFG would but depends on settings.. but yes, for the support thread really, this is for the "im in" and "Hell yes!" posts.. |
