Yes, from reading the blog posts about Q&A related to the AntMiner R1... it pretty much sound like its a device they want you to point your miners at.

It would act as a proxy... and its cleverly compulsorily linked to your Bitmain account which force you to mine on Bitmain pool's, where the funds acquired would then need to be redeemed through their site.

AntRouter R1 has the following in it's description.


As the Compac enumerates as a U3 might this mean that you could manage a Compac with the R1?

Rich

Quick question here: When getting near to the 500Mhz mark, what voltage should you use for stability?

Here's our "setup" (we're going to sell them with optional fans, with ambient temps around 33.5ºC these dys, it is gonna need them).

Thanks! One of the libs was refusing to download, it's working now though!

Got it working nicely

Yes, I'm running them on a Pi.

Are you trying to click on the .exe from within the desktop? If so theres a bug to where cgminer will not write a config file (just writes a blank file).

Or if it will not build, try following the instructions I posted for Pilipma to build and they should work for the Pi (if your using Raspbian):

That's how I set my Pi up.

Thanks for the feedback all! I really appreciate it...

I have hubs like that 4 sticks at 150mhz may work okay

as for what you hub can do 3amps  x 12volts = 36watts  x .8  derate for 24/7/365 = 28.8watts when the volts convert from 12 to 5   you lose some juice  so 28.8 x .9 = 25.92 watts at best  28.8 x .75 = 20 watts at worst.

this is 4 stick at 6.4 watts best or 4 sticks at 5 watts worst

so you may be able to do your four sticks at freq 200   24/7/365 

my guess is real world the four sticks do freq 150 24/7/365

TLDR: The power supply can supply it, not sure if the supply is designed for 100% load 24/7, probably not. I don't know. But it doesn't mean that the circuit of the hub can support the load. Hence the lengthy discussion in the other thread.

Sidehack can probably tell you what mhz that would be, but you can try the math yourself depending on the power you want to push in one stick;
I think its 0.055*Freq = GH at 0.3 J/GH(?) unless you change volt, it should be accurate i think.

You'll need to grab a multimeter or some usb reader and read that thread on how to do it. The thread there also has a link to a good usb current reader.

The question of hubs taking in 12V power has been addressed already with some incredibly thorough discussion. Unfortunately it's in the sales thread instead of here.

Starting point: https://bitcointalksearch.org/topic/m.12440312

Hmm, I don't fully understand the power requirements.

I'm currently running this USB hub. http://www.oricoonline.us/goods.php?id=4937
12V 3A

Does this mean I can run 4 sticks drawing 0.75A safely, or 2 sticks @ 1.5A each?

What mhz would that be?

I ran into the same thing but ended up leaving the "build-essential" off the line and it works great.  
+ the dependencies wouldn't go into the cgminer directory so load into your root user pi directory.

I will warn on powered hub not all 2.0 does the PI's like.  If you have trouble and cannot get to it try to use.   Some have a power feedback - https://www.raspberrypi.org/forums/viewtopic.php?f=91&t=17560 .  If you cannot get the hub to work try the compac directly on the pi and you can see if you have a hub problem.   

I was kinda a pain for me and my hub but I got it working after some reading.

Well, I forgot about the sudo apt-get update, being done first 

As long as you got a good powered hub (2.0 for the Pi's) you should be good to go.

Here's 1 week running 5 stick's on a Pi-2 @ 175 freq. in balanced with 4 pools, so I think that's why the GF is 16, + the phone company has been working on the lines, which doesn't help, but still managed to get a best share of 197M (now all I need is ~65B share  ).

Deleted the rest to shorten

try:
then try it

well bugger me.. i was halfway typing this and sorting my workshop

Beat me to it

For completeness sake though, when doing a new install on a Pi it's a good idea to go through the full upgrade process, like this:


On a resource limited machine like a Pi this can take a really long time.

I did an sudo apt-get Update

/fixed !

Yes, the server where the files are, has been having some kind of trouble or they limited traffic.

It did it to me the other day, just wait a little while and try again, eventually it will come back up and you can get the files. Or you can search around for another source server and add them to your /etc/apt/sources.list (I think that's it).

I am the same way and have a big interest to hear Sidehack's official cause of death.

Sidehack, I appreciate you being willing to send one out under warranty. That's a standup decision and I hope people recognize such.

I am going to PM you to confirm any RMA information, the ship to address, along with discussing ordering a couple more.

The more I play with these bad boys and develope some of my more

 

You're welcome. Post some picts when you've got your rig set up.

The only downside of egg crate is that when you cut it, you can end up with a jagged edge. You can scrape yourself on it if you're not careful.
