Software and instructions are up here: https://litecointalk.org/index.php?topic=28691.0

At the very least please download bfgminer and make sure it runs on your system before you get your stick so I can help with resolving any software issues. It should start up and go to the "add device" screen.

Any way to find out about software and instructions somewhere else as litecointalk is down Sad

Instructions have been transferred over to the second post of this thread here: https://bitcointalk.org/index.php?topic=1248914.msg12967980#msg12967980

Sorry guys I haven't checked this thread in a while. Litecointalk got hacked and its still down, I'm going to take all the info from the support thread and either post it in the beginning in this thread or make a new support thread here.

BTW I got batch 2 in, so people that did not order from original batch have one last chance to order. I can ship them out immediately! Just check out the order thread here for instructions etc.

Just finished up a smaller batch 2 for people that didn't get a chance to order batch 1. Stick are available to ship immediately, and since this batch is a no risk and no pre-order (plus pricing went up on everything since it was a smaller batch) price will be $39 + shipping this round.

Payment instructions and the like are the same, so please follow the instructions on the first post. Limit 4 sticks per person this time so more people have access to them!

Say, got a question. Who's the best domestic quick-turn prototype PCB fab? We've gotten prototype PCBs made by SEEED, but they're in China - which is grating for obvious patriotic reasons and because it makes shipping suck for any kind of speed.

I use http://www.pcbunlimited.com

Their Panel share is ridiculously cheap for prototyping if you can wait 5 days, but their quick turn is not too bad either.

I've been playing around with a few moonlanders this weekend and they run much better on the cubieboard. Could be that they have an extra 512mb of memory, as well as the fact that they recognize my 10 port anker hub just fine. The custom minera image I've built will be shipped with all cubieboard orders.

5 Moonlanders at base clock(144mhz) connected to cubieboard.



Nice job on the custom minera interface...looks awesome Wink

I would assume they are releasing the board info so engis and small companies can prep designs to incorporate their 16nm chip....

They haven't released anything...those are just pretty pictures to look at. From an engineering standpoint you need detailed datasheets, pinouts, and IC footprints at minimum to begin laying out a board. Maybe you can get a crude schematic together with the info they have released but thats about it. 
1828  Bitcoin / Hardware / Re: Bitfury: "16nm... sales to public start shortly" on: February 22, 2016, 06:51:24 PM

My guess is that the 'snakey' lines are parallel coms of some sort and the bendy bits are to make sure the traces are the same length so signal propagation times are the same on all lines. Also note the lack of 90-deg corners aside from in the bendy bits. With 90-deg corners a trace is wider across the diagonal of the corner and that creates an impedance disruption in the transmission line at those points.


Yes if you see any "snake" type traces its because they are parallel IO traces to some other longer traces, so they need to make the traces the same lengths hence the snakes. If you check out your PC motherboard you'll see them all over the place on the PCIe and RAM lanes. When your talking about throughputs in the muti Gigabits/s even the speed of light works against you Wink

This does not matter on anything bitcoin related though, since these are very dumb chips IO rates coming to/from them are in the order of sub 1Mb/s, since nothing larger than a couple hundred bytes is ever sent to the chips( and return IO is even less...just an 8 byte nonce return and maybe a few bytes of chip info data).
1829  Bitcoin / Hardware / Re: New Miner X5 on BitFury 16nm chips on: February 22, 2016, 06:35:19 PM
Well if these guys have millions to spend you'd figure they have a least one marketing guy to write up a post longer than 5 lines...and maybe figure out how to put up a legit looking website...
1830  Bitcoin / Hardware / Re: New Miner X5 on BitFury 16nm chips on: February 22, 2016, 05:15:26 PM
I love how some random guy can come on here and post 5 lines about some vaporware, then get endorsed by bitfury, and people like sidehack and I, which have produced miners and have the support of the community can't even get access to a datasheet to make some miners bitfury knows we can make and will sell in the thousands.

Do these companies just love promoting scammers and companies that will end up screwing over the home miners once again?
1831  Bitcoin / Hardware / Re: Solar array starting to look good. on: February 19, 2016, 11:26:36 PM
Looking really good guys, very excited for you!

This is a question for buysolar, if one were to do a PV setup that wasn't grid tied (I guess you would need batteries to buffer) and mining continuously with it, would it be possible to keep voltage produced in DC and regulate to 12V to prevent inefficiencies from inverters and then again from power supplies?

No, the wire losses would be greater than any inverter inefficiencies, plus you would need ALOT of copper. You have to remember even in a 150w 12v panel you looking at 12.5 Amps of current. 60kw would need copper that can support 5 THOUSAND AMPS of current lol...ill let you do the math on the copper thickness you need for that Wink

This is why most solar setups are wired in series, and some have muti kilovolts running into their main inverters, or simply have an 120v inverter directly on the panel.
1832  Bitcoin / Hardware / Re: Solar array starting to look good. on: February 19, 2016, 11:20:21 PM
Looks awesome...but even building it from scratch with no labor/overhead costs you'd be hard pressed to ROI on this anytime soon. Even if you paid 60k for this setup that would be able to power 20kw worth of miners for free it would take over 4 years to ROI. Guess its worth it if your paying 15 or 20 cent power in jersey, since this will essentially let you mine for the long term and compete with the big players paying near zero cent power.
1833  Bitcoin / Hardware / Re: B-Eleven sha-256 ASIC miner on: February 17, 2016, 07:59:16 PM
Yes 2 - 2.5TH / Board sounds about right. Much as I like the simplicity and efficiency of String designs it is actually quite nice that this is a Conventional Buck Converter based unit, could make for a more reliable unit with undervolting being easier. Also I suspect that the added component cost is quite small and with Miner pricing not seeming to be based off cost it may have very little influence on the selling price.

Rich

Well your look at LEAST 100 bucks in component costs for the buck design in this board. Let say they sell the chip half of what bitfury is so around $5 that will be ~300 bucks, so I can't see them selling this below 400 per 2.5 TH.
1834  Bitcoin / Hardware / Re: B-Eleven sha-256 ASIC miner on: February 17, 2016, 06:38:19 PM
Holy shit...they are using a buck for every 4 chips...thats going to be one expensive board. Seems like every chip has a single tantalum output cap as well...thats insane. Looking at least 2-3 bucks of power components PER chip. Then chip cost on top of this...theyll have a hard time competing with bit fury. Does not seem like each chip can output more than 50GH based on the inductor either.

EDIT: Each board has 2 6Pin connectors, so even if they pull 200 watts per connector we are looking at ~400 watts per board, or 2.5TH per board, or ~60 GH per chip which is in line with what I previously calculated based on the power buck design.
1835  Bitcoin / Hardware / Re: B-Eleven sha-256 ASIC miner on: February 16, 2016, 11:30:52 PM
Wonder what the price will be. Too bad they won't start selling until April. In April you can buy Bitfurys gear.

And with Bitfury and BW stuff all online by then you'll be looking at  > 2EH on the network haha.
1836  Bitcoin / Hardware / Re: Bitfury: "16nm... sales to public start shortly" on: February 13, 2016, 11:03:51 PM
If they're in immersion cooling board form, they're certainly not going to be selling them.
Why? The whole point of immersion cooling is that it allows using the same boards design as for air cooling. The difference is only in how far the board can be overvolted/overclocked for optimum GH/$. Theoretically the buyer would air cool them to optimize GH/J, which means undervolting/underclocking.
 

Not quite...board density and ASIC spacing for Air cooled boards are big limiting factors. Sure you could slap a huge heatsink on an immersion board, but whats the point when you can only run the ASICS at 50% because of thermal constraints?

HolyBitcoin.com and Asicpuppy.net are the two US resellers, and bitshopper.de is the Euro reseller. They should all have a few units left.
1838  Bitcoin / Group buys / Re: Bitfury 16 nm chips and board design on: February 10, 2016, 06:32:49 PM
From what I see declared interest for 35000 chips so roughly 350 k
May be you should think about starting a tread for the people just to express interest in terms of quantities/USD.
The leaked chip price is 13 USD and I think it will be better with 1M order


It was 1M for a full lot of ~75k chips. That already has the discount Wink Not sure they can realistically maintain this price with current diffs and halving soon. Even if we optimistically get a working miner by April, bit fury will have already added their 16nm hash to the networking by then which is at least another 500 PH. We would be looking at a diff of about 200 billion by then, which translates to a profit per chip per month of about $2 for 3-4 months before halving.

Chip would have to be bought at under $10 per to be profitable. (of course this does not count costs for actually producing a board/miner etc).
1839  Bitcoin / Hardware / Re: Bitfury: "16nm... sales to public start shortly" on: February 10, 2016, 06:17:23 PM
Yea they either use 7000 or 7100. Depending on what temps they want to run the chips at.

Here is my "testing" immersion tank running 7100  Grin https://www.youtube.com/watch?v=p5-BaH8_SAk
1840  Bitcoin / Hardware / Re: Is the Anker USB 3.0 7-Port Hub a suitable port for USB mining? on: February 10, 2016, 06:04:31 PM
Thanks for your answer. I was looking at the Sidehack sticks, although I am doing this on a budget right now so I couldn't afford many of them. Such a shame that it doesn't work on the Raspberry Pi. Probably because the drivers aren't compatible with ARM processors

just install Ubuntu on a PC partition and make it double-boot;
it works great and ubuntu installer is smart enough to give you a choice between windows or linux on each restart.
Alternatively, Superbpag (USB 3.0) and Plugable (usb 2.0, but slots can handle up to 1.5A) are known to work with rasp pi (any of them, including pi zero).
BTW, gekkoscience sticks DO work great on rasp pi, of course, just not with that Anker.

I can confirm that the Anker hubs work fun under Windows/Mac with my scrypt USB sticks, but it does NOT work with the RPi (others users are saying no linux systems in general...it has to do with a bug that the Anker USB 3.0 chipset has).

I do agree the the Superbpag is hands down the best hub for any "USB Stick" based mining.
