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.

It's not a bad idea you can test it out and make sure you can get it compiled. It should not be to hard if you are use to Linux.

But yea Minera is mainly for those who like the GUI. I like having the OS there and just using terminal to run the cgminer instances.

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 Wink

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.

1) is 100 percent correct Novak did a amazing job with compac-cgminer. It works great if you have a RPI to throw it on it's even better.
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.

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.

No, the actual data transfer over the USB port is small. It could probably be handled with USB 1.1. USB 3.0 is complete overkill in terms of transfer rate.

The only thing is some usb 3's tend to have more power for usb sticks it would be nice. But RPI does not like a lot of powered hubs and usb 3.0 at all.

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.

This is to avoid raspberry pi crashing (details not provided)

And he's using u2 not u3

Hello everyone Wink

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

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 Wink

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.

Jeff.

This is honestly the best comparsion on hubs still. I'm sure there are some other ones not on list but here - https://bitcointalksearch.org/topic/which-usb-hub-to-use-with-block-erupters-nanofury-nf1-bpmc-red-fury-ant-u1-253749

You can look at all those hubs. And a modded hub could go higher. I personally have not modified any of my hubs though.

Well, 3xU3 give me enough BTC so I can actually pay for something

I have a bunch of 333Mhs and they're still running for fun, because the fractions of BTC they make will never be useful.

The U3 will pay for themselves if not the electricity they use

(i'll post a screenshot of their power usage tomorrow as I monitor them closely)

Fractions of Btc are important and you someday may be biting your tongue on that thought. Short term isn't the best way to plan your venture and I wouldn't recommend Btc now as a payment method or an income....just acquire and hold if you can but for most of us it is tough to do.

It's actually pretty good on payment. I mean I have used it on quite a few miners, it's neat to use some of it at times.

But I agree longterm your goal is to collect as many BTC as possible and hold longterm. Even if you look last few weeks it's had a decent jump on price. I think and hope long term keeps looking promising.

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 Grin

)
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 Huh

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 Grin

Cheers,

Jeff.

No there is not a current discount code that I know of currently. He is not making a ton off of sale already on Compac's. So with being in stock he's actually pretty dang fair since few have stock selling until bath 2.

Hi everyone Wink

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 Wink

Jeff.

The RPI can be a pain on hubs. This explains the problem's and some that are tried - http://elinux.org/RPi_Powered_USB_Hubs

So basically go 2.0 and look at power. I good example of power is here - https://bitcointalksearch.org/topic/which-usb-hub-to-use-with-block-erupters-nanofury-nf1-bpmc-red-fury-ant-u1-253749 Someone might post a good one. Mine I just had laying around in my parts.
