just out of interest, what accessories do you get with the single miner?

+1, does this mean cables + suitable PSU?

I found the item on their website, it includes cable + PSU

as I'm noticing from here: http://www.raspberrypi.org/wp-content/uploads/2012/10/Raspberry-Pi-R2.0-Schematics-Issue2.2_027.pdf
the +5v from the power section and +5 from the usb section are wired togheter, but if you get power from the usb, you are bypassing all the buffer/filter/protection section on the input part of the raspberry... or I lost something? how long have you modified the hub in this way?



oh I didn't know that! thanks for the heads up, I might have to re-think the wiring..

hi to all,

maybe someone already had post about this, but I need to know how many u1 I can connect to a raspberry:
my plan is to connect 2 Dlink DUB-H7 7-Port USB 2 Hub to the ports of the raspberry. How many u1 I can connect to each hub? 1 port will be for the fan, anyway, and I know one of the 7 ports is not usable... so 10 u1 is ok for a single raspberry? I'm worrying about the bandwidth mainly

what if I want to overclock @ 2,2Gh/s? will be a problem?

I have 8 connected to mine, along with a 120mm fan on a 10 port hub. It's all running happily from a 5A/5V power supply and uses 26W at the plug. I've modded the hub so the Pi takes its power from the hub to reduce the cable clutter.

great! overclocked? can I ask what usb hub you are using?

I run them at 2GH (clock=x0981)
This is the hub: http://www.ebuyer.com/259359-xenta-10-port-usb-2-0-hub-mains-powered-wall-mountable-n-uh1001?utm_source=google&utm_medium=products&gclid=COa4743MxrwCFYjLtAodoCIA8A

This is the PSU: http://cpc.farnell.com/powerpax/ptd-0505pa/ac-adaptor-5v-5a-regulated/dp/PW02604?in_merch=Products%20From%20This%20Range&MER=e-bb45-00001003

I have that same hub with a 8A psu.
What mod have you done? Soldered a cable in the +5V rail?
I have 4 Ants @ 0A81, 2 BE OC'd @ 447 and one normal BE in that hub.
I have other hub I can't plug in it, I had to plug it on the computer, since whenever I plug one more BE, 2 or 3 BE go zombie after sometime. Even the Ants get wrong clocks, so I've wondered if it has anything to be with the mod.

There is a diode which stops power going the wrong way up the USB host cable, I just soldered in a wire to bypass that so that the Pi can draw its power from the host cable. It isn't necessary if you power the Pi from another plug, but I wanted to keep the rig as neet as possible.

8 + hub + 5a power supply

http://www.middlecoin.com/ pays out in BTC, they multi-mine Scrypt coins and convert for you before paying out. Probably the best use of your GPU at the moment.

Hopefully some others will jump on the bandwagon, this may even lead to a BTC value increase Smiley

Here is my little setup..

Are you making any coins out of this?Huh

Sorry to ask but I though usb miners were a lost cause.


At the moment it gets about 80p a day in Bitcoin, or £4 if I sell a 24hr 'contract' on ebay, if I sold up today I'd be in profit on the equipment so I keep a close eye on the resale prices. Not looking to get rich tbh but it's a good platform to play/learn some Linux.

I still don't get it.

Did you make a ROI on them?



ROI on a U1 is about 4 months at current difficulty, so I'll mine for a while then sell them, hopefully be a little in profit at the end.

I use Screen on my Raspberry Pi, it does just what you need.

Install Screen, then type 'screen' to get to the prompt. Next start your miner, you can now disconnect putty and when you re-connect run 'screen -r -d' to get back to the screen.

You can also start off more 'screens' by pressing 'Ctrl-A' and then 'C'. Switch between them using 'Ctrl-A' and then 'N'.
20  Bitcoin / Mining / Re: controller for antminer? on: January 31, 2014, 11:53:11 PM
No, you just plug them in and run the latest BFGMiner with this parameter

-S antminer:all

So I guess your PC is the 'controller'? (#noob)
