I have tried and using [ Monoprice 12-port USB 2.0 Hub w/3.5A AC Adapter ] in my setup I'm running 7 block erupters on it nicely and due to the nice round shape there is plenty of breathing room between all of the erupters for heat dissipation.

UPDATE: These didn't show signs of issues at first but I have since discovered that only 6 devices can be on these at once otherwise they stop being able to communicate with your miner properly.

Would you mind providing more information on the DC barrel plugs and where you got them?

They are 2.5mm x 5.5mm DC Barrel plugs, the "short reach" or 9mm long plug . I got them from a local electronics retailer (Surplustronics), which unless you are in Auckland, NZ, won't be much use to you :|

The wire I used is "0.33mm^2", I would have used 0.5mm^2 if the had it in stock, though.

what would be cool would be if these had fold out male connecters in the bottom so that you could stack them.

I already ordered one from a local on-line shop, should be delivered tomorrow. The price for started kit was ~$100, including Raspberry Pi Model B Revision 2.0 board, 16GB SDHC, micro-USB AC adapter, HDMI cable and case. I think I'll manage to install MinePeon using the guide you referenced before. I am still waiting for Canary to send the miners, so I'll have ample time to play with the RPi.

That eBay link will surely come handy for others.

Is there any cheaper way then powered hubs? Can you get a powered usb 3.0 pci-e card that uses sata power or other power, then use regular hubs on it?

Just was wondering. Was not sure how much power a sata usb 3.0 powered pci-e card would have for BE's to run.

I have one PCI-E card in the table. However, you'd still need powered hubs, if you want to run se more than 4-5 miners off it.

any suggestions to replace Anker hubs since they're currently not listed on Amazon? The copycats are more expensive and seem to have less ports working.

You have Anker 9-porters. I removed the 10-porter links, save for the German Amazon - they still have 2 in stock Wink

Added it to the table. It looks like a variation of a 24-porter, which was already listed. This 12-porter seems to have one of the lowest prices per port.

Out of curiosity, what is the best place to buy Raspberries?
I found one here for $43:
http://www.ebay.com/itm/Raspberry-Pi-2-0-Model-B-512MB-Version-Element-14-Linux-System-Board-/290946215548?pt=LH_DefaultDomain_0&hash=item43bdbeee7c

Is it a good buy?

it's not a bad price for the R-Pi circuit board alone, but have look at eBay link below for an R-Pi with Minepeon...
EDIT. forgot the link http://www.ebay.com.au/itm/Raspberry-Pi-Bitcoin-Mining-Host-Preprogrammed-/261257041142 Tongue

which includes the following:

   1 - Raspberry Pi Model B Revision 2.0 (512MB)
   1 - Clear ABS Case
   1 - Motorola USB Wall Adapter
   1 - 4GB Samsung SDHC 4GB SD Memory Card Class 4 -Preloaded with MinePeon
   1 - Basic Instruction Manual

you could score the R-Pi above at a good price, it would save some time and you can still try your own setup on another sd card.
usually kits with parts above go for around $80 - $90
1 day 6 hours till auction ends from now.

Link? what link? Tongue

I am thinking of grabbing a bunch of these:

http://www.mcmelectronics.com/product/DISTRIBUTED-BY-MCM-CK-0027G-/83-11765

They are available from a local store for $6.75, and have a 3.5A power supply ( I physically looked in the box). Due to the configuration, I only think 6 ports would be usable though. However, that is pushing $1/port!

That is great to hear. Do you have it running on a RPi?

No have not tried that.... I should actually, I'll look at getting one but may be a while before I can confirm...

Updated on my hubs

I now have 3 hubs operational with 23 miners in total, 18 on my PC, 5 on my RasPi.

Power consumption of Raspi + hubs + miners + PSU less what is being leeched from the PC is 40W (or so my Watt Meter tells me, but I don't consider it that accurate...)

Hubs US$9.50 each (DX Bulk price FTW)
PSU US $34 (not from DX, sourced
DC plugs and cable US$5
Not burning my fingers soldering US$priceless

Once I have four hubs going, that's a total of $77 for 36 ports, or $2.14 per port - though I am tempted to limit the total used to ~32 to not stress the PSU (17A including the RasPi, out of 20A max), so maybe $2.41 per port.

Improvements to make - ~6A polyswitches for each hub (10 for $4 on ebay...)(the hubs have no over-current protection!), convert some more of my 30cm USB extension cables to power isolation cables, power the RasPi directly from the PSU, not from a hub.

Pics:
Hubs, Duct, PSU, RasPI. The black power brick is providing the 12V for the Fans. The PSU is now running very warm to the touch (still far cooler that an USB Erupter) with the extra 5 miners and RasPi. Is was only warm before add that extra load.

miners all cosy in the duct.

Would you mind providing more information on the DC barrel plugs and where you got them?

Verifying that the 13 port Juiced Hub is only 3000mA.

And for the curious, verifying that you can do side-by-side on the horizontal spacing.

Couldn't you do this with no soldering by just cutting off the power supply wires from the wall wart at the base, and connecting them to the screw terminals of the power supply? I guess it depends on whether the wires could handle the extra current.

The wall warts supplied with the DX ones I got are rated 5V 1A, I've lopped of one plug, and the cable to the plug looks like 8 x 0.1mm wire. So, no, probably not a good idea to do that, which is why I've bought some 2.5mm DC plugs and 13 x 0.2mm wire (0.33mm^2), which is somewhat better.

And I also bought a load of 30cm USB extension cables from DX, which are handy, as they have a clear-ish molding, which I've used to isolate the powerd hubs by drilling through the red wire in the plug, to create some isolating extension leads.

so the black orico 10 port usb 3 hubs from the aliexpress website seem to be arriving with 3A power cords instead of 4A as listed on their product description. but i ordered on july 30th and it arrived today from hong kong.. so thats pretty fast... i bought 2, and have 9 BE's in each one running fine so far...

do you have a link to the one you purchased? i may want to give one a try

Link 2 in the OP table. DopeLabs, the white one is actually cheaper.
Don't know if I should update the table with 3A info. Was it a delivery error or they consistently supply lower-powered AC adapters? Anyone else with Orico experience?

Quote from: merv77 on August 05, 2013, 12:24:59 PM

the RPi uses 5 watts of power and compared to even an efficient laptop it's half the power.
they're not expensive and easy to setup, I used this guide to get me up and running... https://bitcointalk.org/index.php?topic=251675.0
