How many can you run on one Raspberry Pi?

Bought a set of 10, I hope they arrive soon

I'm going for a raspberry setup, does that thing need it's own powersupply?
How many greedseeds can I hook up on 1 Raspi, I've read 20, but it doesn't seem confirmed.

20 with the "stock" 10-port hubs (I'm currently running that way), 26 with 13-port hubs like this: http://www.amazon.com/gp/product/B00HL7Z46K

It gets more complicated after that, since you can only have 2 levels of hubs on the Pi, and the 10- and 13-port hubs already have 2 levels inside them. Something like this might work, depending on how it's set up internally: http://www.monoprice.com/Product?c_id=103&cp_id=10307&cs_id=1030702&p_id=6436&format=4

Looking forward to hearing your results...

My geek brain thought something like this would be amazing: http://www.engadget.com/2010/01/29/80-port-usb-hub-makes-you-feel-like-a-powerful-soldier/

Edit: never mind, it charges only, no data Sad

Yes, and why bother?

Yes, it has the necessary amps. Just make sure the BTC core is disabled.

But, why bother? If you only have one miner, then steal power from the PSU on a computer. If you have more than one miner, then get a computer PSU to power them all.

I want to sell my GPUs and buy more than one GridSeed,and I can buy in my country charger such like that form amazon link under 1$ per pcs. (charger voltage is stabilized),and this is more profitable from me buy several chargers under 1$ per pcs. than 12V 5A charger or PSU.

So this charger schould be ok for only one gridseed on scrypt mode only ? (I don't want burn it)

If you are Dual mining it needs to be at least 12v 5amp. But for scrypt only it needs like 12v 1amp.

It should work i think when i did the math it was 0.6a but you would be better with 12v 5a power supply. If you over volt you destroy the gridseed example anything above 12v. If you under amp you destroy the power supply and that in turn may cause a problem with the gridseed. You need to make sure it is center positive and gridseed can use either 2.1mmx5.5 or 2.5x5.5 end.

Getting rather irritated at mine. The constant need to babysit makes it a royal pain in the ass. They constantly drop out/disconnect/stop accepting shares/get bugged out in random ways. Simply having cgminer restarting now and then does not help either, as I often need to re-plug or power cycle them, as sometimes they simply disappear from /dev/ upon restart.
Going to try connecting them to another PSU, try yet another hub, try connecting to another computer. Suspect shitty firmware/design though.

I'm using Inland 13 port USB hub. Been using it for weeks now with no chronic problems until yesterday.
For some reason the ports are re-setting, or just quitting and leaving my gridseeds hanging at 'dispatching work to gridseed" mode but no results coming back as expected.
Every 6 or 8 hours it seems, so far but this is only the 2nd time.
It didn't do that while I was mining on LiteCoinPool.org. Started doing it after I pointed them to ScryptGuild.com - Not sure if this is the cause possibly? That's weird, if it is the cause.
I'm using Win7 on an Lenovo R400 laptop. I doubt that's what's causing it....
Darn it! I thought I was good to go! CRAP!

So I hit a USB limit in ubuntu... I have 120 gridseed 5-chip devices plugged into one linux box and getting this message: no more free ACM devices.

That is a limit of USB 2.0, 127 devices, including each hub.

In theory, that is the limit of the controller, not necessarily of Linux. If all of your USB ports (on your computer) are tied to one USB controller, then there is nothing you can do - with those ports.

You can try to put in a PCI-E USB card. That may give you another 127 devices off that card.

Cool going to find a PCI-e card

They've been running very smooth for 24 hours, 31 pieces deliver a steady 9,5-10 Mh/s. I'm using two raspberry Pi's. Cheap hubs and the controllers from Lightning Asic were the biggest problems with me before.

Hey, I have a 13 volt, 120 amp power supply. Would that work for 100 of these things? I have successfully used it on rechargeable batteries for RC cars, for charging car batteries, for jump starting a car without a battery, and for a bunch of 12 volt devices.

I would be concerned about the quality of the power. How steady it is. You risk burning out the gridseeds from over volting.

Now, if you regulate it down from 13+ volts to 12 volts, that would work. But, by the time you do all that work, you might as well buy a quality PSU.

does anyone no if theres a DIY guide on how to make the power cords for a modular psu for these gridseeds?

You want 2.1mmx5.5mm barrell plug. At Radio Shack, they are the Size M plugs
http://www.radioshack.com/product/index.jsp?productId=2103614

From your modular PSU, you want the yellow wire to connect to the middle of the plug, and the black wire to connect to the outside.
The maximum power draw of the miner is 60w (dual mining), or 5 amps at 12 volts. That would imply 11 gauge wire.
However if you mine Scrypt (litecoin) only, the power draw is 7 watts, or 0.6 amps at 12 volts. That means you can use 20 gauge wire (or lower number).

This wire would work:
http://www.radioshack.com/product/index.jsp?productId=2036271

A 6 pin PCI-E connector is rated for 75 watts. A 8 pin PCI-E connector is rated for 150 watts. They both have 3 yellow wires. To be safe, do not try to draw more than 75 watts from a 6 pin PCI-E connector (3 miners in scrypt mode per yellow wire). Make sure you use all the black wires - A different black wire for each yellow wire.

Use a volt meter to confirm the voltage at the plug (positive is in the middle) before you plug in your miner.

If you do not like to soldier, you can use something like this:
http://www.amazon.com/Gino-2-1x5-5mm-Power-Adapter-Camera/dp/B0058RLD9C

Be careful of these. They tend to be 22 gauge wire, a little thin for Gridseed:

I just ended up buying 12 of these cause they were available for overnight shipping.

I should be fine if i splice this wire and use it like the single pig tails right?

That will work perfectly for Scrypt only mining. I would not even try it for SHA mining though. Too much current to pull through a single feeder.

What is the part number/supplyer info, if you please?

Thanks!
Wolfey2014

got it on amazon

http://www.amazon.com/Female-2-1mm-Plugs-Power-Adapter/dp/B004EAHJAG/ref=sr_1_2?s=electronics&ie=UTF8&qid=1394499921&sr=1-2&keywords=female+2.1mm+jack+to+8

Right, well, perhaps I wasn't clear enough. I mean the single MALE connectors and wires going to each plug are probably okay to use for mining but DO NOT use the single pigtail / end!
They don't specify the wire gauge size of that setup. So I'm figuring 16 gauge which is good for around 3.5 amps MAX! But, the wire gauge can be anything. Even 22 or even 24 gauge which is like telephone wire! Maybe good for a half to 1 amp MAX! You won't know what the gauge of the wire is until you cut it off the pigtail and strip it. It might be worthless for hashing actually, so don't be impatient or hasty and risk frying your power supply or worse, your mining pods.

So, cut the thing into 8 separate plugs. Strip and connect each plug's wire end to the main power supply.
Make sure you check and keep the polarity correct throughout the entire process. Center conductor is + Positive +.

If you want to pigtail them off of one wire from the power supply, use 14 gauge minimum which is good for up to 15 amps. Mining S-CRYPT is low power consumption but even at 1 amp each, that's 8 amps at the input wire which is too much to draw through it.

As usual, do this at your own risk! You fugg it up, you eat it!

Good luck!
Wolfey2014

I got one of those and cut it up but the wires in it are absurdly thin. Obviously video cameras use very little power. I just binned it. Even if the wires dont get very hot there will be an impedance there which will increase noise. Not good.

I read part 3 of this guide and it doesn't help me because I'm ignorant with this kind of stuff and require pics with steps lol This guide is good an i'll donate as soon as I get my miners up and running

There is a link in the op to my post with pin outs for molex and pcie connectors.

I think its labeled making your own cables.

yah I read it but I have no experience so I have no idea what your actually talking about lol

edit: I guess I was looking for something like this http://wiki.ztex.de/doku.php?id=en:ztex_boards:ztex_fpga_boards:cluster_power_supplies

Is this good enough to work for the gridseed power?
