Dual miner Grin
I am wandareing what the hell of buggy fork will be able to efficiently mine on two !SEPARATE! Pools Grin ltc/btc simultaneously ...
And I liked the part when BTC price move up all of us get exited and order and order and finaly all of us home miners get fucked...
The winers are China brothres for sure selling long premined  new machines Grin

Hi, it can run separatelly pools, you need to put the pools on each side separatelly  Wink

Yes from what I've read you can set different pools as it's needed.  One will be a BTC pool, and one a LTC pool.

Hopefully we hear more soon.  It could be interesting.

I love this miner, i can consider to enter into a group buy...  Grin

BTW it is controlled by a raspberry pi using USB (nice detail)
Still seems a bit pricey but thankfully with the BTC rise could only end up being a few coins when it releases.

We are sorry we didn't update the information for a long time.
Due to the uncertainty of crypto currency industry, to lower down the risk, we adjusted our strategy. We suspended our retail market, and focus on our VIP customers and the data center setup by ourselves. Because retail market need a bigger team to provide marketing, sales, customer service and technical support etc. It means the higher operating costs.
We are very happy to announce that our new batch will be ready at the end of Nov. The most machines are already booked out, only left very limit amount of machines. We suspend the plan to add machines in our farm, and now open the remaining batch for sale,  the price will be $1150 for each, and only accept 100+ order. it will be ready to ship at the end of Nov.

P.S.
We already added new wafer order, now we accept the booking for chips and miners.
SF3301: qty:2000+ , $25 per chip, the greater the number of the more discount
(We already open source our miner spec, please find it from https://github.com/sfards)

SF100(or same hashrate, new model): $1050 per miner, qty from 100+

Shipping date: Jan, 2016
Chips are what I am excited for 25$ a chip, lets get someone on making a custom miner stat!

In Sfard's defense, it came out before any of the new chips.....

Only, it didn't "come out". Two, maybe three miners are reported in the wild showing dubious results - hardly the "mass production" they claim  Wink

There are a few more then 3 but not a ton.  They picked a few resellers and sold them 5.  It seems each one got that 5 number.   

After that purchase all quiet on front from SFards on chips or miners.  I think they must be mining internal is my theory.  They  have the only modern scrypt chip, so they have zero competition right now but old gear.
No, they have the only publicly announced modern scrypt chip. No doubt there are others with chips just as efficient if not more hashing away purely scrypt.
There is no way to know this.  Unless you know something the rest of us don't know.   

I think you are underestimating how hard it is to get a new chip, and cost.  For someone to do in house make a chip, then miner on scrypt for it is a pretty big task.
I am trying to find it but I know for a fact there have been warehouses with their custom miners, I will update this post if I find it.

Hello all a little of topic?

Hey @J4bberwock how is the progress on the replacement board for the old gridseed orbs.

Thanks.

I think a big thing would be if SFards is making and shipping chips.  I don't think with the silence chips will be sold at this point to general public.  There are the lucky ones who ordered them early on with dev kits and such. 

That is a good question anyone that was working on a project have you tried to buy chips from SFards in any quantity lately?
If someone missed the train it looks like these people are reselling the dev kits but no extra chips. http://www.aliexpress.com/store/product/Bitcoin-Miner-SFARDS-152GH-Asic-Miner-Dual-Mining-Development-Board-for-Btc-and-LTC-Mining-28nm/1035615_32342132314.html

you're doing the lords work here...

btw...I almost bought that miner from russia...makes me wonder if there's more than 1 of them out there Wink

Ironically their only using what...55nm tech? Imagine what you could do with 7 or even 28nm
Um, check the 1st post here -- it is using 28nm.

Oh yeah, my bad. Thanks.

First off, thanks to carlosmnk for the RPi image.
After pulling it apart and dumping the redisdb file for credentials (wiibox:wiibox), I've got a working miner (with some quirks)

I've also to compiled the miner from github in an attempt to run USB straight from the serial breakout, but received the same "cannot open sfards port" error on each OS. This is different from the "cannot find sfards port" you will receive when trying to launch a nonexistant device.

I believe this is something related to the CP210x drivers, as the serial board uses an uncommon quad port PN.
They really are just giant versions of the USB Dualminers and Gridseeds of yesteryear.

Also worth noting, I've got two different hash board revisions across my three blades.

I'm traveling all week but will post detailed pics and a sanitized image with DHCP enabled when I'm back.

While these chips are too cool to completely ignore, i do see why they had to abandon the project.
The sheer number of parts it takes to build a hash board is staggering, especially considering that this miner was launched when both BTC/LTC prices were much lower, and had recently been through a nosedive to sub $400.

Damn shame.
Had to buy mine broken from Russia, they just never made all that many.

There should be a way, but nobody is reporting back...

So we won't know without obtaining one for ourselves.

Is there a way to run this miner? Just interested in the scrypt mining.
Thank you.

After trying for what seems like years, I finally got my hands on an SF100. (Yay...?)
The miner was shipped to me without the RPI, so I dont have any SD cards to image onto a new Pi.
If I load up a new Pi with Rasbian, and compile the miner source from the Git repo, can someone confirm that's enough to get one of these moving in the right direction?
I'm not sure if there's any software/firmware related to the breakout boards and their GPIO interface.
Thanks!

If you can compile the sfards miner source on rasbian it should be enough to get the cards hashing.

You should also be able to connect them via USB to any linux box as long as you compile their miner software.

Worst case scenario you have to find a way to operate minera(the wiibox controller) on your rasbian.

If you run into any problems or have success please report back to us.

Thanks.

Does anybody have a sfards sf100 that is working right now I am thinking about buying one cheap, I have read the last couple pages of the forum and was wondering how you ran yours? I have a silverfish up and running it was a pain setting up but finally got it I also have two hurricanes one has four boards the other has 5 I bought on eBay before I really knew much about this mining but don't use them anymore due to how much power the use and heat they produce.

I think you can run sfminer (available from their gitpage) on linux to hash with the boards. I never bought a sfards because I'm not sure.

At least the company was nice enough to leave their Github repo alive https://github.com/sfards/ASIC-SF3301
Chip data sheets and schematics all there.

May want to try & save em somewhere else just in case they disappear  Wink

Electrical engineer. Mining since 2014.
This miner was a huge failure was it even ever released?  Not that anyone even cares now that its totally unprofitable lol
It was released for real, I've seen few used ones in sale here at the forum.
