what is this "Drillbit system" you speak of? is it another Klondike16 clone?
No, the DrillBit system is not a Klondike 16 clone. It is a superior design to the Klondike, designed by our engineer here in Sydney. Got any pictures or CADs and specs? would be interesting seeing the difference of the design, i assume the design is not under the open source hardware? If anything, fill us all in on the development on the board.. .. i may just move my weight behind this from terrahash |

Tell me, who is the people that are working with terrahash?
Who can voice the opinions and work of terrahash?
Basically what I'm asking is, terrahash doesn't say much here, but a few has a lot to say about what is going on. I'm new to following the works of terrahash, I thought things were ready to order about a month ago (till i looked into it more)
I don't mind waiting, i see no scamming going on yet (unlike some paranoid people claiming it all a scam), but if people are claiming to work for terrahash and taking money/coins off people, i'd like to know who is and isn't working/helping terrahash and who is/planning to scam people.
Sorry to throw this wrench in the works here, but I Would like to know who to listen to (knowing that terrahash is busy working on this project).

So.. looks like these things are not ready, that's fine, i thought you already made and sold these. Ah well, im going to save my moneys in btc.
what is the ETA on the finalization of these boards? when can i put an order down?..
on the other hand terrahash, care to do some trade? eg: had full of chips for a couple of boards? probably not worth getting 50 chips for 2 boards, you'd enough to make 1 more board and some..
If not, i could throw the 6BTC at you for 2 boards, i think that little extra could help
Ether way, i need to get up the BTC and/or the chips...

I just want to know, what makes them scammers? they Have shipped the 1st batch, if you follow their blogs/tweets/etc. you Will see the problems they have dealt with? no, lets call them all scammers because you don't talk to them and you haven't got your product yet.
you try selling out a costly mistake of 10K dud chips from misaligned Photo-lithographic mask. these guys are not Intel or AMD you know.
am i on their side? no, they could of marketed the whole thing a lot better then this, they should of accounted for these issues.
one thing i do look at is more then one side of the issue. BFL has an angry mob at their doors, i don't join the crowd, i look for why they are there.

not to bump or anything, whats the best course of action? or just sit back an laugh at my stupidity ?

Hmm, if the asic chip is on the top of the PCB, and the heatsink is on the bottom, what is it sinking? and why is there no pictures of that side?

Can anyone see a simple adsl modem motherboard in that picture on the main site? i can see a phone line plug (the grey port) next to a inductor coil (the yellow and black box next to it) the yellow network connector, next to a switch, next to a barrel type power plug? with the caption under the picture: "mage above: main control board + my ipod and mouse for scale." and that soldered aluminium can is EMS shield for the SoC...
sorry, when i looked at the post, clicked the link, passed all other posts and went eh, no, obvious fake...

 We've only a handful of mods here, and there's no mod with the similar spelling with 'Complicatedlyfun '. yeah, i relies that now, it was a kick in the teeth for me |

Yep, im another (and 1st time) BTC-e sucker, late comer to the game, and hoping to get things going in life TheFed was to trade me 225LTC for 6BTC, simple, used a 3rd party to be a escrow called Complicatedlyfun (notably a play on simplefun's name) who clammed to be a mod. https://blockchain.info/address/1DKrxqnL846vfJPcgGoLR7VELYrbfexEDF is my 6btc split and moved into a wallet and up for trading i balive TheFed used a 2nd sign-in to pretend to be this "mod" and take my money.. just to add, From Complicatedlyfun +225.00 LTC LTC payment 10.05.13 12:51 from:LMTfkV8GJek7PmxgJrvkK1uJsJpnqPy2sQ Please send 6.000 BTC to: 1DKrxqnL846vfJPcgGoLR7VELYrbfexEDF then from TheFed Nevermind, he messaged me. Complicatedlyfun 12:56 10.05.13 +6.000 BTC BTC payment 10.05.13 13:07 from:1KSn7nioqjKiKwv288phYtjELZ8h8fAfES Waiting for confirmations then funds will be released. |

I use very aggressive fitter settings, effort multiplier of 40, that's 2hours of fitting  Thanks for the tip, I've been using the default settings so far but I'll give the more aggressive ones a try. Makomk's code did eventually compile (for 120MHz clock) and gave a fmax of 123MHz at 85C. This should be giving 30MHash/s, though I'm not convinced I'm seeing that in practice. Possibly the fpga is running a bit too hot, though I'm not seeing any bad hashes. I'll have to run it a bit longer to be certain. [EDIT] Its actually working perfectly. I cranked it up to 140MHz and it seems quite stable, pushing out 35MHash/sec! Not bad at all for a DE0-Nano. Cheers makomk  Regards Mark wow, now im in, 35MH/s = $5 a month... at max of 5W? now if i was going to replace my setup now thats pulling 200W, i need 100 of these, and that beating my 190MH/s setup! (35 x 100 = 3500MH/s!!) and thats just the DE0-nanos!! now, wheres my $10,000... |

fare enough, didn't think of this... hell, i'm still to new to understand how the whole pooling system works, but i know it works, and well

So, how long till shares are paid?
going by the page i have paid Valid: 0 Invalid: 0 at 237Kh/s for the last several hours, and i have 8739 Valid unpaid shares..

hi, another question from a newbs..  have any of you guys heard of parallella? http://www.parallella.orgwhat you guys think about it? Ahh yes, that my friend is a completely different ball game to FPGA i've been waiting for them to kick off, i want one to play with 64 threads per chip... mmmm |

NO!! Don't confuse gate with LE (logic element). Older fpga's often quoted a gate count (such as the one you linked to Spartan 3E 250K gates). Newer fpga's use a Logic Element (or Logic Cell) count (and google tells me there are 12 gates to a LE). So a Spartan 6 LX150 with 147,443 logic cells roughly equates to 1.7 million gates by my calculation (I can't find any direct quote for the actual figure, so take that as very approximate). You can see the spartan family spec at http://www.xilinx.com/support/documentation/data_sheets/ds160.pdfThe board you linked to will be (almost) useless for mining. You need to look for a purpose-built Spartan LX150 based miner and use the firmware (bitstream) that comes with it (and even then the economics look pretty grim). If you want to compile your own bitstream for the Spartan series, you can download free software from the Xilinx web site http://www.xilinx.com/products/design-tools/ise-design-suite/ise-webpack.htm but beware that it is limited to the smaller devices (LX75 maximum I think, but do your own due dilligence). You need the full (very expensive) version to compile for the LX150. Regards Mark Ah, Sorry for my newbishness, never played with one of these devices (blame the 2 companies for their heavy secretive efforts unless you buy their $5000 suite) my mistake, so when a company quotes "Gates" number, i have to look for ALM, LE, Slice etc? Basically i want to know what a full miner roll out fits on, how many LEs i'll go to digi-key and look something up and go from there |

the nano i was looking at does have "two CDs with the software necessary to 'compile' and 'upload' code to the board. " but not sure if the EP4CE22F17C6N is usable
The DE0-Nano is great to get started learning about fpga's, but it won't make you any useful coin. 5MHash/sec is about right, it will go faster but not without risk of overheating, and certainly no more than about 25MHash/sec (using Makomk's modified power supply). To put that in context 5MHash/sec will currently earn approx 0.0003 bitcoin per day (and getting less by roughly 20% every 2 weeks as the difficulty increases). If you do decide to get a DE0-Nano, start with the DE2_70_Unoptimized_Pipelined project. You'll need to increase CONFIG_LOG_LOOP2 to 4 to get it to compile (that's one eighth of a core, I think). I cheated and edited the fpgaminer.qsf file directly to configure it for the EP4CE22, but its probably safer to create a new project from scratch and add in the source files. Mark Heh, thats about $1 a month (at the ~$100/coin mark) so that thing is not going to break even this life time i thinks So, i might have to go hunt out some 2nd hand Spartan6 with 150K gates (or similar) So the question is, will any 150K gate fpga work with the full miner? or is there something I'm missing (EG: http://www.digilentinc.com/Products/Detail.cfm?NavPath=2,400,790&Prod=BASYS2 with 250K gates, slap on the full miner, and bam, 1hash a clock? ) |

that's outside my budget pricing.. would be nice though
if i can get a cheap and nasty going, getting half a dozen coins over the next few months, then i will get one
My biggest problem was software. If you're going for used chips, make sure whatever chip you buy has free development software for it. Wanting licensed software for a dev board is one of the reason I bought the kit. the nano i was looking at does have "two CDs with the software necessary to 'compile' and 'upload' code to the board. " but not sure if the EP4CE22F17C6N is usable |

I have just pushed the experimental KC705 code to the repo.
.... AJR, If you're going to get into it I would highly recommend you get the 705 or the 701. ... that's outside my budget pricing.. would be nice though if i can get a cheap and nasty going, getting half a dozen coins over the next few months, then i will get one |

So, looking into this whole mining with fpga system, and this code you people are working on, what is the required Logic cells/gates required for a full roll out? also whats the smallest unit you can get it running on? (the bare minimal for a half roll out (what ever you call it?)) I just want to dip my toe into the FPGA mining with a cheap and nasty chip set  just tell me to piddle off else where if its the wrong spot to ask AJRGale, I think you'll want at least a Spartan6 LX150. This is the cheapest device I would use. I would only run a fully pipelined implementation -- one that can do one hash per clock cycle. If you can get a hold of a Kintex7 or Virtex7 board you'll be a lot better because you can instantiate more miners. fpgaminer has posted a lot of useful code on github. I don't speak Altera, so not sure on specific devices. so 150K gates? like a Cyclone V? (no idea what gates to logic cells ratios really are) ...so that means 75K gates for half miner? Ether way, cant find a Spartan6 LX150, can find a http://www.adafruit.com/products/451 "DE0-Nano - Altera Cyclone IV FPGA starter board " a miner could run on it, buut, only the smallest one to what I've read out of here, at 5Mh/s... maybe i should look at the code and work out how to use the dev suite, maybe it might tell me what it needs to run i have no idea what I'll be looking at though :/ |
