101  Bitcoin / Group buys / Re: [CANCELED] [GROUP BUY] Hashfast Babyjet 1.09 btc = 2.5%, serraz ESCROW. on: September 02, 2013, 11:50:52 PM
Sad news on the Baby Jets.  They are currently ranked the highest in ROI and you had a good idea with this group buy.

http://cointerra.com/product/terraminer-iv-2ths/?added-to-cart=18

We can still do group buys for these beasts.  Shipping later so they are ranked just below the baby jets.

Also I am planning to have you ship my chip order directly to me and have not heard word of setting up a payment option or shipping address.  I think I PMed you once with an address but need to edit the address now.  I am moving and will be hosting Baby Jets and Terrahashes while I build with the chips being sent to you.

Thanks for the hard work marto74
103  Bitcoin / Group buys / Re: [OPEN] - GROUP BUY of BITFURY Chips + DRILLBIT SYSTEM mining assembly on: September 02, 2013, 07:45:03 PM
I think it is safe to assume hashfast will not ship until November at the earliest (given they just taped out a few days ago). There may be 550-1650 MPP chips shipped out by HF in Feb 2014 needing a PCB home. HF have said they will provide an open source ref design for 3rd party builders.

are you guys working on 28nm systems?

We have a few possibilities in the pipeline for our next project. Main priority of course is to get this one done first, but yes keep your eye out for upcoming Drillbit mega boards. Thinking seriously about Cointerra. What do you guys think? The main issue is that their stuff is huge so it won't be very well suited for small scale mining. Though there might be possibility to set up a few community based minifarms which everyone could chuck in for. Something like that.

Anyways, in the meantime, Bitfurys baby. One thing at a time. Got something special for you any minute now.  Wink

Barntech

IHMO that is great news that they succeeded in tape out.  But by Feb 14 the Baby Jets I offer open source hosting for will have chewed into the difficulty quite a bit. I am not sure if there would be enough interest in us creating CADs for HF chips that late.  Why not open up reels and gerber files at the same time as Baby Jets?  Unless they are offering us new technology to develop on I am not interested.  Maybe they think their chip will still be interesting by then.

It will be refund per chip 0.086BTC minus 5%...

I think that this is fair compensation for all the work you have put in over the last few weeks finding out the intentions of hundreds of buyers. If you didn't charge a fee I was going to tip you something anyway so call the 5% a tip... Smiley

Some of us are not as wealthy or rich liked you, we have a couple of mouths to feeds and rent to pay every month, well if some of us  request for full refund may you consider their request. "stripykitteh" could always give more of his generous donations.  Smiley

Given the risk in getting chips late and the rising difficulty, I call getting back 95% of what I put in not a terrible result. I'm not in the habit of giving out donations for nothing, but sometimes you gotta take the deal that's on the table and move on.

And if i am not wrong, unless you were the one buying btc when it was 250 usd to purchase,  then you have made money by the way btc has risen in value?
105  Bitcoin / Hardware / Re: Klondike - 16 chip ASIC Open Source Board - Preliminary on: September 02, 2013, 03:52:25 AM
Were there not updates to the design since the last firmware update?

There are no chips to test on since the last update I am afraid  Grin

So no there have been no updates made publicly since the updates made on the public github
106  Bitcoin / Hardware / Re: Klondike - 16 chip ASIC Open Source Board - Preliminary on: September 02, 2013, 03:51:22 AM
Is there a precompiled cgminer binary to run K16 for linux?
My github repo has the compiled cgminer in it. I haven't tested it on anything but my own Ubuntu 12.04 but presumably it will work on other Linux 32 bit releases. You would git clone it to your system. If using ARM (RasPi) or 64 bit you would  have to compile, which isn't hard at all. Just a bit slower. There are no drivers to install. With cgminer what we call drivers are actually just modules in compiled into the main executable.

The steps to compile (for ARM or not) are:
(go to the directory where you want cgminer directory created)
Code:
sudo apt-get update
sudo apt-get install autoconf libtool libncurses-dev yasm curl libcurl4-openssl-dev pkg-config libusb-1.0

git clone https://github.com/bkkcoins/cgminer-klondike
cd cgminer-klondike
./autogen.sh --enable-klondike
make
Do that line by line so you can verify errors before continuing.
I just tested that on my system and it took only a few minutes to download and build.

Compiles and runs on my Ubuntu 12.04 VM without error, other than "no devices detected".

I just did this and it seemed to compile fine.

When I run it, it says

Started cgminer 3.3.1Segmentation fault

I looked up segmentation faults and I have no idea what is going on....some kind of error..

Anybody have any ideas?

I get the same fault when I run regular cgminer (not clondike version), but not the cgminer-nogpu

Could be a gpu issue. It's an AMD machine running linux mint 14, based on ubuntu I think, with a 7950. I think I installed the linux drivers on it, but I have not installed the opencl sdk...is it even necessary for klondikes?

No clue here. Thanks for any help in advance, especially Bkkcoins for all the work so far.


That post mentions that everything is really just another module added to the main cgminer executable. Klondike "drivers" are essentially cgminer source code with added "modules" code.  Think of it like counter strike from half life.

Error is most likely due to some error in the cgminer GPU as you suspect!

I'm starting to think ye olde Avalon ASIC sitting on this here olde laptop is about to ROI  Grin

Cointerra is offering 20 500 GH/s chips for $57,000. A little steep but a 500 GH/s http://cointerra.com/shop/. This would be a prohibitive price I think.

And sorry for the late edit.. thank you for this reply. 

Price is getting high to be a small developer these days.  Cointerra is not the only ASIC developer so I don't really care much.
108  Bitcoin / Group buys / Re: [OPEN] - GROUP BUY of BITFURY Chips + DRILLBIT SYSTEM mining assembly on: September 02, 2013, 01:10:26 AM
are you guys working on 28nm systems?

They seem like a smart group of developers and in past posts have suggested they have a team member named Dan that is privy to VHDL and other hardware description languages that would qualify them for developing on 28nm.  To my knowledge there are no 28nm silcon ASIC developers offering reels of 28nm to open source PCB devs like Barntech.

I would love to hear if I am wrong on that  Grin
109  Bitcoin / Group buys / Re: [OPEN] [GROUP BUY] Hashfast Babyjet 1.1 btc = 2.5% / WE HAVE ESCROW NOW on: September 02, 2013, 12:55:42 AM
This groupbuy is for 40 shares of a hashfast Babyjet. It is not for a cointerra unit. This groupbuy has conditions of having a weekly picture and weekly receipt as well as zero hosting fees, minus power costs. These are conditions that those other group buys do not meet. This groupbuy is for a hashfast unit, not a cointerra unit. If you want to merge group buys, then there will have to be weekly pictures and zero hosting fees. You say sorry for trying to steal members from this group buy, but you do so blatantly while still trying to do so. Why are you sorry for being disrespectful when you are actively doing the action. I did not go to your posts and try to steal your members. This is not supposed to be a fight, nor war, nor competition where one group buy does a takeover of another. If you want the groupbuys to merge, then offer zero hosting fees, zero escrow fees with someone well known in the litecoin community. Furthermore, your shares are overpriced given the current market conditions. Our shares are 1.08btc and lowered every time bitcoin goes up. I do not like the idea of hidden or extra bitcoin fees. I ask for transparency, which your group buy does not offer. That is not a well way to start off.

I apologize for having it seem as though I am stealing buyers from this group.  

I pledge to contribute to your Baby Jet GB as well.  Much in the same fashion a pledge would be held by other GBs

I have pledged my assistance to others since I will be located close to them and it is only logical and aids trust.  I would do the same for you if logistics supplied such outputs.
110  Bitcoin / Group buys / Re: [OPEN] [GROUP BUY] Hashfast Babyjet 1.1 btc = 2.5% / ~12.5gh/s (overclock speed) on: September 02, 2013, 12:02:28 AM
i will think about doing escrow if theres enough interest in this. Altho the way OP was just talkign on my channel ill have to have a big think about it.

It is good to see people reasonably talking and considering.  I am open for any help that I can offer to any group buy on hosting any miner at no profit.  I want technology and freedom meow.

Question everything... I really do not want to help people get scammed.. or give all of these hopes of secure almost free hosting and then whoops.. ASIC dev screwed you again.

Agreed i like to try and do what i can for the community. Main reason  started my pools. My issues are al these asic companys offering deal that are to good to be true. The personality of the Person preforming the goup buy also has a impact on the group buys. usally if there offering a deal that would mean everyons loss is the same then i guess as long as your willing to accept the loss on your part its ok but thats up to each person.

I am trying to find the most open source and secure solution to these rigs.  I love your work on the pools.. really cool to go to your site and see 0% plastered everywhere.

I have been working with bobsag3 who will be living close to me.  He has teamed up with UltiBit Cointerra Group buys... this may be a direction the OP and others should consider... I plan to host anything I can for the community.

I am also considering starting a group buy for my facilities location where truly open source prices will be the hosting % fee.  (My Father's large facility so all of the fees are up to him.. i could just say they are gaming towers hogging his dual ISPs data and kWh but he has a PHD in CS and is privy to the network and willing to see his son work).

The fees will have to go back to 1% soon (gotta pay for servers Sad) i still think its fair tho. Appriciate your feedback on the website we spent alot of time on the pool. If you do decide to use us for hostign pleaase let me know and we can work out somethign to help your group or hosting area we are always looking for new ways to support what people want.

The BTC pool needs some love Cheesy were still workign on new features to draw users Cheesy

I just want to say the way you communicate about your fees is enough for people's support.  I intend to do the same.  All fees are reserved for ISP and kWh costs.. actually trying to donate the dual ISPs for as long as possible. More importantly I want fees to be debated by the community for hosting.  The community and share holders get to decide fees.

good to see ur0pl posting again.. I am sorry as well for hijacking your posts and wish you the best of luck and I offer you my services if ever needed.

I have pledged to the ultibit cointerra and hope everything can be merged openly.

Regards!
111  Bitcoin / Group buys / Re: A little help to decide if you want to do a groupbuy or not... on: September 01, 2013, 11:55:11 PM
The wait time on my group buys are usually less than a week and it's insanely stressful making sure everyone is informed... I couldn't even imagine handling a single group buy that lasted 4 months! Sad

Sebastian really does offer up an epic case of group buy.  Perhaps his stress can be shown as the optimal case of a hard working GBC.. but realistically we may never see that high of stress again.. or at least hopefully not for awhile.  Grin

I think a Group Buy of SJ's size and duration should only be taken on by the most ambitious GBC, preferably with a core group of 2 or more people. I don't think a GB of your size/complexity should be undertaken lightly by anyone.

Seeing the size of those chip Group Buys, for comparison's sake it took 14 other buyers & shares purchased by myself to purchase 40 shares for a HF BabyJet in my recent GB, and it still took a lot of work behind the scenes to keep running smoothly. I'd say any new GBC should learn to walk before they run & *focus* on just one Group Buy of limited size/complexity/duration. There's a lot to be said about not fighting two or three front wars.

Be prepared to deal with distrust and a lot of time spent educating others and answering questions. Also, look at yourself honestly and ask how well you deal with customer service and teaching others.

- How will you handle concerns about BTC handling and for miner rigs: miner payouts later on ?
- Hosting details? Everyone kosher about where the hardware is going?
- How will you deal with refunds? Do you have funds set aside for this?
- Will you have co-admins in case you get hurt/incapacitated or if there's concerns about fraud?
- Are you willing to risk your time, your job and your freedom to give Group Buyers the world's best prices?



Sebastian shows that it is possible for one person to manage 300+ people,

And you have to factor in all of the complications that the original company offered for all of those really coordinated people like SBJ.  They were able to take a largely fractured buy (things only got more complicated when people started freaking out about ROI and sold off GB purchases to others.. this was good actually since I got a few chips this way as a developer), and were able to reasonably talk to all of their friends that bought with them through the whole struggle to the final resolution of refund or no refund.  

I just don't think those terrible courses of events shall play out for awhile in the BTC community.  Or I'm just hopeful.

Either way these group buy leaders for Avalon show'd greater face than the company they were buying from.  Perhaps these Avalon GB coordinators could give customer service advice to some non-bitcoin related companies I can think of  Grin

Thank you for the answers!

So, it seems that if you get it by or after October then you will be never make ROI, no? Based on current diff rises.
http://mining.thegenesisblock.com/a/2060a6ffde

Good to see people calculating difficulty here again.  I would say that kind of depends on your definition of ROI.  On paper it may seem that you won't ROI.  But people don't always factor the increasing price of bitcoin and its popularity into their ROI. 

IMHO.. to see project developers work openly with the community adds an immense amount of ROI value.. even though you can't use the black pen to right it down.
114  Bitcoin / Group buys / Re: [OPEN] - GROUP BUY of BITFURY Chips + DRILLBIT SYSTEM mining assembly on: September 01, 2013, 11:08:33 PM
So from what I understand, if I order the thumb then it costs $104 including shipping? The assembly and whatnot is done in the USA, or in Europe/Asia?

Do they have the chips already for the currently in stock thumbs, or are they waiting for a shipment from bitfury?

Do we have any idea for time frame if we order right now? (1 Week, 2 Weeks (tm), a month?).

The Jhon K escrow does not cover issues such as late shipment, correct?



* Updates Aug 17th

  • Chips ordered! Big thanks to Dave at Megabigpower for allowing us to secure a reel at the old price, because the prices are going up!
  • Board design finished. Photo up


These fine folks are in Australia I believe.

Above says they were ordered on 8-17.  Bitfury expects to ship by the end of this month... and people have been receiving bitfury on time... Barntech is then expecting a quick turn around on assembly time to have the products shipping October-November.


So I just finished reading everything properly...

Have I correctly interpreted that a "DrillBit Thumb" is going to power 2 bitfury chips and cost approximately $100 USD?
And begin assembly in October



Hey stack.

We are leaning more towards the 1 chip thumb at this point. Pricing is not yet locked down, but it will definitely be sub $100. And yes, shipping Oct/Nov

Cheers

Barntech

Here is the return policy of the company ordering chips for this group buy.

Hope that helps your questions.

Have you guys seen Ultibits group buy? What would everyone here think about merging there?

https://bitcointalk.org/index.php?topic=282645.0

Seems very professional to me and I will be living two hours away from the host and have pledged my assistance to him.  I can also host myself if there is high enough demand.

I fear it's too late for any group buy targeting HashFast batch #1. Only 15 machines left:
https://hashfast.com/shop/babyjet/
They will almost certainly be sold this evening. People are moving too slow, and to be honest opening poster haven't exactly put this group buy into high gear, posting only once or twice a day.

I'm not a big fan of Cointerra's estimated shipping date, mid-December if I understood correctly. They are very low-risc, but you can probably get bigger reward with a bit more risk.

Too bad we can not organize one decent HashFast group buy/hosting.

I am with you on a babyjet.  That is the original gruop buy I wanted to start and SebastianJu was kind enough to answer my questions about starting one.  I agree though with only 15 left now it would probably be too late.  

We could organize a post perhaps have Sebastian hold funds till enough are gathered.. again this would probably take too long.. we seem to be the only two interested at this time, and I do not want to waist anyone else's time.
116  Bitcoin / Group buys / Re: A little help to decide if you want to do a groupbuy or not... on: September 01, 2013, 07:54:12 PM
As one who was considering starting a group buy I can say this has probably saved me exponential amounts of headaches.  

I was lucky enough to ask questions before starting anything and SebastianJu is very professional and helpful.  Most group buy starters are very open and will answer questions.  As stated above these guys have to respond to hundreds of PMs a day so it may take a few days, but I have always heard back.

Keep the community and the hard work shown from the Avalon buys in mind is what I have concluded.  I may still perhaps start a group buy if the community seems to back an idea.

So - yes, you can count me in as committed under two conditions:
- Organize John K. or some other respected member as escort, I'll send 1.1BTC
- If we can not collect enough committed people before HashFast sells rest of batch #1 (35 left, see: https://hashfast.com/shop/babyjet/) money should be sent back immediately, no group buy for later HashFast offers without miner protection.

Good luck to everyone who want to grab this opportunity!

I think merging the group buys to accelerate the group buy completion is a good idea, if you can get it organized.

I will commit to 2 shares at 1.1BTC each (2.2BTC Total) under the same conditions mentioned by itod.

I will also require the organizers personal info (name, address, phone, scan of driver's license or passport), in case of fraud.
Thanks

Is it correct that marto74 purchased through the sebastianJu group buys?  I saw his name on an order for batch 6 of his buys.  

Sebastian is currently refunding batches 2-5 of his group buys I believe.  Keeping 1 and 6 in hopes they will be delivered quickly after all of the refunds.

Well "avalon" left him no choice on batch 6 order... he can't get a refund on those dates at this time.

119  Bitcoin / Group buys / Re: [Group Buy] Avalon ASIC Chips (SebastianJu) Batch 6 ordered (Closed) on: September 01, 2013, 07:59:00 AM
Oh and... 3 Refunds are safed. I received the bitcoins. So now 2 batches and the 6000 chips from batch 6 are on order.

I wasn't aware that we couldn't cancel group 6 chips. I put in my cancel but the chips are still coming? I don't believe you mentioned that 6 could not be cancelled when you first mentioned the
refunds, did you? (Perhaps later but I haven't followed the whole thread.)

I'm a bit confused here. (And I know you are overloaded with work regarding this refund and I think you should be compensated,) but perhaps there are others in the group 6 buy who thought they
would receive chips last and so also cancelled?

Thanks,
IAS

Avalon is posting refunds to orders purchased before certain dates. I will not provide you with these dates because they keep changing and the information is out there for you to find.  Sebastian is doing his best to return the refunds offered to him. 

Some people still would rather receive chips in your group buy IAS as it is about sharing.
120  Bitcoin / Hardware / Re: Klondike - 16 chip ASIC Open Source Board - Preliminary on: September 01, 2013, 06:27:08 AM
Like anyone would buy any second gen avalon.... let's keep this on track.  99% of the community want a refund because they only wanted to profit.  1% just want to do research to secure the network.

this is where we stand.

All numbers in statistics are subject to bias.
