Its CAN-BUS all boards are wired in parallel on the differential bus lines.
The flat cable will run through all connectors of one stack.
I see. I would expect that Enterpoint also used a bus and just looped through the two connectors. I like their concept, since it enables to stack say 16 boards very easily: you need to build 15 equally length ribbon cables (8cm) and connect boards one after the other. I suppose it is more complicated to build a long cable with equidistant plugs to connect 16 Bitburner boards, but might be wrong. You could use cables with 2 headers on the end instead of the board having 2 connectors. somilar to Y-molex cables for case fans. |

But instead of having some fair distribution scheme based on what people paid for, I now need to be the arbiter and decide whom to send samples. Make three friends and 20 enemies - thanks Avalon.
turtle83;OWN;1 PS: Thats not for sample chips. Thats to booking for the friend slot. Guys hurry up 2 remaining. |

I hope I'm getting others like knc and bitfury. But these lancelots should be able to reprogram. Someone will have to spend a lot of time doing it though.
no they wont be. I dont think anyone can mine scrypt with sparatan 6.. you need really fast memory |

I'll buy 200 @ 0.5 each to resell on my site.
I would be willing to buy for .6 if you did that but we need to see where the price is going to level out at. Hopefully it will pop back up to at least 115. from a buyers perspective, if ur pricing mining equipment in BTC, price of btc:usd should really not matter... since these things are for mining bitcoins only, your ROI would always remain in BTC... skip converting to scam currencies  Their issue is that they have to purchase the raw equipment in fiat. thats the sellers problem. Right but if bitcoin goes to sub 90, sub 80, or even sub 70 these miners will be more expensive because of the cost it takes to make them ALRIGHT I'd take 200 @ 50$ each then. But avalon chips are priced in BTC. if 1 BTC price becomes $1000 ... then the chip itself is worth $78...  |

Yes, is indeed good news, so hopefully in another 2 weeks to received the Avalon Chip?
The way things seem to work my guess would be more like 4 weeks. Not sure about that. The payment for bulk chip manufacture is still sitting in Bitsyncom's wallet. Also they have a responsibility to fulfill their Batch 2, 3 and the poor sod's from Batch 1 Avalon's that still haven't received their unit first! That would be seriously sly to f**k those guys over by prioritising the bulk orders over their units. Their time for ROI has already significantly diminished from what they were led to believe... So you what ur saying is... even if the foundry finished building the chips, they should hold off shipping those until they can finish assembling batch 2/3 of the full units? Sounds a bit selfish dont you think? |

I have a problem with cgminer on my AsicMiner usb erupter.
3.1.1 works fine, but 3.2.1 gives me this never ending series of errors:
[2013-06-08 19:38:12] USB init open device failed, err -3, you dont have priviledge to access - AMU device 1:9
[2013-06-08 19:38:12] Icarus detect (1:9) failed to initialise (incorrect device?)
[2013-06-08 19:38:17] USB init open device failed, err -3, you dont have priviledge to access - AMU device 1:9
[2013-06-08 19:38:17] Icarus detect (1:9) failed to initialise (incorrect device?)
[2013-06-08 19:38:22] USB init open device failed, err -3, you dont have priviledge to access - AMU device 1:9
[2013-06-08 19:38:22] Icarus detect (1:9) failed to initialise (incorrect device?)
.....
The only usb connected mining hardware is the AsicMiner usb Erupter.
I set the same permissions on both 3.1.1 and 3.2.1:
-rwxr-sr-x 1 andrea dialout 304853 May 24 09:46 cgminer-3.1.1/cgminer
-rwxr-sr-x 1 andrea dialout 1160140 Jun 8 19:35 cgminer-3.2.1/cgminer
Running debian 7.0.
copy the 01-cgminer.rules into /etc/udev/rules.d/ and restart udev. the permission of the cgminer executable doesnt make any difference |

So who supports this? blackarrow or asicminer? i.e. RMA, warranty, etc ...
tip: Bundle this with a PSU, cooling solution, preconfigured with overclock/volt you can probably make markup off n00bs too scared to attempt by themselves.

What a great idea with the Jalapeno! I have a Jalapeno on order and need to order a Raspberry PI to get on the learning process. Is there any documentation on how to set up the Raspberry PI for this? I note this one site for setting up the OS - Minepeon : http://mineforeman.com/minepeon/ Would this be the easiest OS for the PI? I have questions like: How does the PI connect to your mining pool as it is all command line based, yes? (Do you set up an account and then manually enter the settings of the account into the PI???) How easy is it to control the PI from your computer via your router? Input guys would be greatly appreciated for those of us without a ton of computer experience. Ive not used Minepeon, i just use a striped down version of Raspbian. Seemed pretty straightforward to me, but then ive been using linux for a very long time.. I never hooked a monitor/keyboard to my pi, ever. Only use ssh to set it up. From what i read here on the forums is that most non-linux native people use Minepeon and are happy with it. |

raspberry pi is perfect. u could go with more expensive beaglebone black, or perhaps TP-Link TL-WR703N which is cheaper but you may have a harder time with it if u don't know your way around linux. Whatever u buy you would need a powered USB hun. these tiny things dont provide the needed amps. For raspberry pi, the power is 5V (same as usb). so if you pick the right hub, you could power the pi as well as asicminer from the same hub, so one power adapter for the whole rig. Now, if you can USB tether from your phone, you could (in theory) connect it to the pi (or other devices) and suck interwebs from your phone. if u cant usb tether, then ud need to buy a wifi dongle. Id say look to spend abt BTC0.5 - BTC1 on the project. The tp-link comes with wifi onboard, and i assume u could set it up to be a guest, so if u buy the tp-link then you dont need to buy wifi dongle. Bonus. get a battery setup that gived you > 1.5 Amps @ 5V .. then u can mine on the go... |

I want to sell my graphics card. purchased on April 9th this year. I paid equivalent of (342.611 USD) for it. This is the one with 3 fans, runs cool and relatively silent.
Working fine, no issues, only reason for sale is I needed the ATX PSU for other purpose and dont want to buy a new one. Also im not into scrypt mining, and this is the only GPU mining unit I have. For sha based coins, its really useless.
Never overclocked voltage.
It mines scrypt @ > 650 kh/s @ ~71C at 25C ambient in case with cover open.
Most popular card currently for scrypt mining. Ill probably be willing to sell for 75% of current market price for new. That puts it at 2.18175 BTC.
I have the original box, crosover cable, molex to pcie power adapters (2 pcs).
Ships from Thailand. I will give you original invoice as well which has 1 y warranty. But if you want to RMA later for any reason you would probably need to deal with Thai distributor. Dunno, not my problem.
Shipping/Escrow buyer pays.
Just exploring what i can get here. If i get the 75% target then its convenient for me, otherwise finding buyer locally maybe headache.

same here... Same issue with Ubintu. downgraded to 3.1.1 again. |

[edit] using sudo got around the permission issue, is there a better solution? I'M MINING!!!!!
ls -lh /dev/ttyUSB0 ull see that it likely had group permissions for dialout. u need to add that to the user ur logged in as. sudo usermod -a -G dialout yourusername Then your user has permission to talk to those interfaces |

*sniff* *sniff* ok, i need some hand holding. I grabbed the tarball from GIT for the latest version. I copied the files into my cgminer directory (this is 32 bit Ubuntu), over writing the existing files. I ran autogen.sh and then make. I plugged in an ASICminer USB stick. the green light is on. then i ran ./cgminer with no parameters. It started GPU mining fine, but didn't show anything about the ASICminer. Do i need to reboot with the USB stick plugged in? or is there a start parameter that i need? Please don't tell me to read the readmes, i did. and i'm terrible at searching 100s of pages of a thread. I did the group join thing in the Readme.
stop cgminer now unplug the USB thing plug in the usb thing back in. ^ Not troling. im serious. save this file https://github.com/ckolivas/cgminer/blob/master/01-cgminer.rules as /etc/udev/rules.d/01-cgminer.rules sudo service udev restart download cgminer 3.1.1 (for sake of clarity into new directory) ./autogen
./configure <the arguments u normally pass> --enable-icarus
make ls /dev/ttyUSB* make note of the devices. run cgminer cgminer <arguments u normally use> --icarus-options 115200:1:1 --icarus-timing 3.0=100 -S /dev/ttyUSB0 -S /dev/ttyUSB1 <repeat for each usb tty device>

Thanks a lot for doing this. You created this thread while I was typing a suggestion to do exactly this. One suggestion is use bitcointalk.org in the urls instead of IP. Many people don't want to accept uncertified SSL connections. |
