Here is the link for the PSU I have ordered. (shipped but will not be here for a couple of weeks?) http://www.amazon.com/dp/B0076UJVSY/ref=pe_385040_30332190_pe_175190_21431760_3p_M3T1_ST1_dp_1

and just going to use the cheap 10 port hubs others have used

so thinking of going with this

I'm really interested in how that would work :-)

Please send a link showing the power supply if possible.

The Tek Republic TUH-2700 is on sale at NewEgg for $13 for the next day or two. Linky.

Remember that it can run max 5 miners. In that respect D-Link with its 6 miner capacity is a better bargain.

Perhaps, but the tek republic plus a 5v4a supply from ebay for 8 bucks gives you 7 working ports for 21 dollars instead of 6 working ports for 35.

I have a couple of those hubs. One tek republic from newegg and the other a cables unlimited rebrand. The power plug looks to be 5.5od/2.5id but I will confirm next week when the 8 buck supply arrives.

What gauge of wire do you use?

This says only 3.5A, what if you pushed it to 5? Would it burn out?

I copied the wrong link and updated, I meant the 5v supply and not the 12v supply.

I wonder, what would happen if you crossed this:

Thoughts, Ideas?

Probably would burn the circuit because the hub is 5V and power source is 12 V. Someone correct me if am wrong. But the voltage should be same and we can work with higher amp. correct.?
I burned by wifi router recently in one of the experiments like these.

Would something like this work? I'm really nervous about soldering the board directly.

When you talk about the PSU, do you mean something like this?

http://www.ebay.com/bhp/5v-40a-power-supply

How does the 5v translate to the 12v? Thanks for helping me out with this guys.

Thanks,

Great point about the red wire and back feeding power to hubs if one psu goes down.

Today, I am switching over to 90 amp psu's and using the 10 amp models to power small 6Gh/s (18 eruptors, 1 fan, 1 wifi stick) rPi units.

With barrel connectors, I found the screw terminal ones from amazon to be garbage at higher amperage, eventually burning out and sometime melting apart in the process. Most likely you can use any connector that is crimp or soldered, or premade (as long as it's a decent wire thickness). It wasn't the female aspect of connector on hub that shit the bed, it was my cheap male ends, so soldering leads directly to usb pcb is most likely overkill and not needed if quality wire and connectors are used.

how do you chain them together? do you have 10 ports feeding into a 10 port hub? i've run into wierd problems with some miners randomly not launching when chaining hubs

have you cut the RED wire in the USB cable..?

I'm not sure how your hubs work, but when the hubs are powered through the power supply there's no need for the RED wire in the USB cable.

If it's not cut then you'll get one hub powering the other via the RED wire.
you can test this 'power-backing' theory by plugging one hub without the power supply plugged in, into a hub which has the power supply plugged in and then plug one usb erupter in the hub without the power supply and you'll probably see it power up. It's safer to cut the RED wire, because if a power supply fails then only erupters in that hub go down. Otherwise more will go down as more power supplies get overloaded.

If you're not sure about what I'm talking about, reply and I'll try and take a couple pics of what I did to my cables.

Is what your saying if the red wire is not cut and you lose one power adaptor on a hub that it will then want to overload the next hub's power adaptor and make it blow as well.

I have a 5v 40a power supply coming, have my 5.5mm power plugs and more of the cheap 10 port hubs (like in the picture above) coming and plan on powering to start four 10 port hubs with the ability to add another four in the future.

Would you mind posting links to the hubs, DC power plug and power supply?

[joke]No, no, no, cut the green wire first, then the red one, or it'll blow![/joke]

My 30 BEs arrived yesterday, while I only have 3 D-Links in hand (with 2 more + RPi on the way estimated tomorrow).

So far, all 3 D-Links run stably with 6 Erupters each and no daisy chaining. The remaining BEs were spread all the available ports that I could find. Grin

The only caveat so far is that D-Links' power units are rather warm to the touch.

Once I have the remaining hubs and RPi in place, I plan to connect 4 D-Links via a powered 4-porter hub that I had from before to one of RPi's USB ports and the remaining D-Link directly to the other port. That way I hope to run all 30 off one RPi. I'll report back with some pics over the week-end.

This is the problem I ran into with the monoprice hub and why I had to come back and issue a correction to 6 units instead of 7 being supported on them, at least in my case they were just barely short on the power, or the block erupters used just barely too much and then I'd get them randomly not found when starting my miner or some started showing 100% HW errors, as soon as I dropped 1 erupter off each of the hubs then they all started working flawlessly. So make sure you have enough power.
