Thanks a lot for your quick answer notlist3d 
2) Not really Minera is like a miner OS for dummies (no offense to anyone using it). It has great nice gui's, and there is a image that supports the copmpac.
So it really deepens on no 2 on what OS you want to run on a RPI.
Ok, so i think i won't need Minera. I'm going to compile the cgminer source from Novak this afternoon (even if i don't have the compac in hand yet). Cheers, Jeff. |

Hello everybody Thanks for your answers.
But if usb hub needed for U3's you can use cheap no power usb hubs to RPI. And you will have no issues with it.
In fact, i bought a GekkoScience Compac recently. The device arrived at the forwarding company warehouse and is in transit to Europe. I can't wait, but i should get it soon  I had the felling that i will have more fun with the compac rather than the Antminer U3. That beeing said, i might have more difficulties in finding the right USB Hub, taking into account the Raspberry and the Gekko specifications. Regarding the softwares, can you please let me know if my understandings are correct: 1) the official cgminer software should work, but novak wrote a custom cgminer for the compac and it's better to use it. 2) Minera is a software that can be used to monitor the device. Since i registered to Slush's pool i didn't really need Minera. However, Minera will useful if i join the more confidential sidehack stick pool. Binaries can be downloaded, but it is adivised to compile the source code with the right options. Am i right? Cheers, Jeff. |

Hello everybody:)
Knowing that the raspberry pi only supports USB 2.0 hub (and not 3.0), i was wondering if this limitation would impact the mining performances...
Cheers,
Jeff.

Not related to zombie This is to avoid raspberry pi crashing (details not provided) And he's using u2 not u3 Ok, thanks zOU |

Hello everyone I don't know if it related to the Zombie we were talking about, but someone noticed that when using Antminer & bfgminer software, crashes can be fixed by adding the line: slub_debug=FP in the following text file: /boot/cmdline.txt For more info, visit: http://hawkcreation.com/raspberry-pi-miner-bitcoins-cles-antminer/P.S.: Feel free to move this post in the software section if necessary. Thanks. |

You might want to double check that 3A per port.
I think it's the power supply that does 3A.
I didn't paid much attention but after checking i think you are right I might want to reconsider my choice, although this device should theorically be able to power 5 miners. The typical hash rates for the Gekoscience compac (if not overclocked) is about 8Gh/s. Efficiency is .31-.35 watts per Gh/s, so each device need 2,8W. The transformer seems to be able to deliver 5V with a maximal intensity of 3A, that is a total power of 15W max. The maximal number of compacs which can be connected to the HUB should be: 15/2.8, that is 5. That beeing said, the calculation is perhaps too optimistic and theorical. Not to mention that the transformer might become out of shape quite quickly... |

On hub it was in a different language I did not translate. Main thing to look at is power it provides to each port or overall. You want a good amount of power.
According to the specs it looks as if this hub can deliver up to 3A per port. Regards, Jeff. |

Hello everyone, some news: 1) Just placed an order at asicpuppy for 1 GekkoScience Compac (if everything goes as expected, i'll probably buy more  ) Just wondering is there any discount code valid at the moment for this shop? I made a google search but the only one i found didn't work  2) Regarding the Hub, i think i'll go for this one: http://www.amazon.fr/gp/product/B0000B0DL7?I hope the plastic won't melt Cheers, Jeff. |

Hi everyone Thanks a lot for these useful informations. I think i'll go for the GekkoScience Compacs. Looks as if this device is great. Still have to decide where to buy it. It looks as if nobody beats Sidehack prices. That beeing said AsicPuppy shipping costs are lower and the item is in stock (although Sidehack should restock it soon). Regarding, the powered USB HUB, which models would you suggest? I know that the HUB have to be chosen carefully with the Raspberry, so i prefer asking. Thanks again Jeff. |

Hello, Thanks for your posts. So to sum up: if one doesn't take into consideration electricity, the U3 has a better ratio: Hash rates/price of the set. Would it be reasonable to think that 1 U3 = 4 compacts ? However, i looks as if the power consumption of 4 compacts is inferior to one U3. Am i right? I didn't get any answer from Sidehack yet, but here is the answer of Asicpuppy (the other us store selling the compact): "Yes, I’ve got a good amount in stock. I have raspberry pi model B’s and cubie controllers pre set up for mining with the compac. Software-wise, the Compac is supported by bfgminer and custom builds of cgminer." Btw, if somenone could explain me in a few words what a "zombie" is Cheers, Jeff. |

If the rendering is correct in stick forum they will have a different heatsink. So as far as usability should be the same. But it looks different and i like to collect sets. So no real justification on getting one besides I like collecting sets. Ok, i understand better |

Not sure of bitshoppers source of chips. But Bitmain sold 1k chips to sidehack. They are using those chips on the US/Non-Europe compacs. If you have a good mail forwarder like you said you can put in a order to get in queue. Currently it's between batch 1 and 2 it should be less than 2 weeks from when me made the announcement.
The recycling of board is more for a future product from Sidehack. The pod, it is still in dev though.
I already sent a PM to Sidehack to know the availability. So the device is assembled from "new" spare parts? How did Sidehack manage to sell it for only $25? I mean it is the price for an "old" Asic Miner Block Erupter 330MH/s at amazon... Cheers, Jeff. |

I keep thinking the will have them in sometime. Not sure of timeline though. To be honest if renderings are right I might want a Europe one - https://bitcointalk.org/index.php?topic=464496.0 . I like owning set's. So not sure if I will manage to get one of those for decent to US or if they even will sell one to US. Have you asked the seller in email or anything if they are close? Actually, i haven't contacted them yet... I might send them a mail and ask for a timeframe tough... I don't know if they ship to the US either, if they don't ship i can easily buy one for you and send it over (don't mind using an escrow)... Me too:) I would be more than happy to do our US members a favor. That beeing said, it's very likely that the two sticks are very similar. Did i miss something? Cheers, Jeff. |

Hello Thanks for the answers. Although, i live in France, i don't mind buying in the US, even if the seller doesn't ship oversea. Indeed, i know and use a very reliable mail forwarder (they have a referral scheme, so don't hesitate to contact me if interested ). From what i understood, both device from bitshopper.de (europe market) and GekkoScience (US market), is build from the same recycle chip board (am i right?). The first batch is already sold out, and the second batch should be available soon, although a little more expensive (but the new device might be more powerful). Did i understand correctly? Cheers, Jeff. |

Hello,
To be honest there is not much to research. If you want a stick miner to mine. Go get one of sidehacks compacs.
No other usb stick can do 8gh let alone 16gh when oc. Raspberry PI is nice as it uses very little power.
It's just that i know it's rude to ask questions without reading first every topics the members provide Still this USB device "sidehacks compacs" looks amazing: cheap and as powerful as the big equipments. Any drawback? Would i have to join the sidehacks pool too? I mean is it just recommended or mandatory? Thanks again |

Hello, Thanks for your message. It looks indeed very interesting. I'm going to dig deeper into the subject thanks to the links provided Regards, |

Hello, Thanks everyone for your answers. If electric is quite cheap a pair of S3 could do well. Not a lot of profit (about $50/month total return right now, something like that?) but certainly better than a block erupter.
I just checked my electricity bill. The company EDF (Electicité de France) sells 1 kWh for 0.10€, then i have to pay a first tax of 0.01€ per kWh, and of course the VAT: 19,6% here in France. I think that most of our electricity is produced from nuclear power stations  . In the early 70's (even if i was not born ) we were told that it would be the cheapest method of producting electricty but it turns out that it is not the case. We have very old nuclear power plants and it costs a lot to close them cleanly  Just wondering: do you pay more or less than me? Cheers, P.S.: I would be very happy to earn $50/month. That's even more than expected |

Hello everybody I'm a happy owner of a "old" Raspberry Pi (model B, and not B+). I installed cgminer, and joined Slush's pool. I managed to make the USB ASIC miner block erupter 330MH/s working. However, the rewards i got are extremely low. Therefore, i was wondering which device i should buy, to get a reward superior to the power consumption. My budget is around $100, although the absolute maximum would be $160. Thanks in advance for your help. Regards, |
