Which USB hub to use with Block Erupters | NanoFury NF1 | BPMC Red Fury | Ant U1

[MonocleMan]

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?

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

Thanks,

Maybe something like this?

What gauge of wire do you use?

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.

I wonder, what would happen if you crossed this:

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.

[MonocleMan]

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

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

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.

Please send a link showing the power supply if possible.

Thanks-Let us know how it works!

[MonocleMan]

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

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

This is an amazing project!

I have 3 Juiced Systems 10 port USB 3.0 hubs each running 9 block eruptors plus a USB fan.  I haven't bothered testing them with 10 miners because I am using the 10th port for a fan.  They have been mining for about 2 days now with no problem.  I actually like their greater density compared to the Anker 10 port.  It makes one USB fan cool them much better.  Since I don't know how to include an image in my post, I posted an image here:
https://www.dropbox.com/s/wvyefiwnkxcu8br/DSCN0174_LQ.jpg

As much as I hate to repeat myself I posted a review of the Juiced 10-port hub in another thread( https://bitcointalk.org/index.php?topic=263577.msg2824064#msg2824064) so I'll paste it here:
-------
I bought the Juiced 10-port from Amazon and suggest getting something else.  It'll run 8 erupters but when you plug in a 9th it starts to lose contact with one, then another, then another and the only way to fix that is either restart cgminer or unplug/replug the miner.  The Anker's extra amp makes a big difference.

Adding insult to injury my Raspberry Pi can't see this hub at all, so I think I'm going to order the Anker from Amazon and return this one.

Are you sure that it isn't a problem with your USB driver or something like that? What OS are you using?  I am running bfgminer on Linux Mint 15 with no problems with 9 Block Eruptors on each hub.

[A_Member]

By the way, does anyone know if a 200khz 150mv ripple would be detrimental to a Block Eruptor.  I'm looking at a power supply currently that has that.

This is very close to what I am doing:

I got this power supply:

http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=290589641496&ssPageName=ADME:L:OC:US:3160

I got this hub (I needed a card reader anyways):

http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=231002957081&ssPageName=ADME:L:OC:US:3160

And for the connecter wire I got this:

I am going to be excited to try it out too, it sounds like we are trying something very similar.

you should be fine but I suspect that the cable might become a bit hot. The product page specify 3.5A max and you'll probably have ~5A to feed 10 BEs.

Yeah, Pidge suggested shortening the lead, I will most certainly follow his advice.
