GekkoScience Compac BM1384 Stickminer Official Support Thread

I did an sudo apt-get Update

/fixed !

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:

Code:

sudo apt-get update
sudo apt-get upgrade
sudo reboot

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

Trying to install CGMiner gekko in my Raspi

sudo apt-get install build-essential autoconf automake libtool libcurl4-openssl-dev pkg-config libncurses5-dev libudev-dev

Getting this =>

try:

Code:

sudo apt-get update && sudo apt-get upgrade

then try it

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

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  ).

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.

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.

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?

[sidehack]

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://bitcointalk.org/index.php?topic=1126705.msg12440312#msg12440312

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.

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

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

[Jake36]

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

Next, Has anyone gotten this to work on a Raspberry Pi? I tried the novak source, but I keep getting: ./cgminer: cannot execute binary file

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):

https://bitcointalk.org/index.php?topic=1173963.msg12468048#msg12468048

That's how I set my Pi up.

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

Got it working nicely

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).

AntRouter R1 has the following in it's description.

4. Bitcoin Mining Host

The R1 can also be used as a controller to manage and run several AntMiner U3s. Connecting your U3 to the AntRouter R1 via a USB hub eliminates the need to keep the U3 plugged into your computer.

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

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.

[sidehack]

If someone wants to test that functionality, groovy. I won't, because I don't feel like buying an AntRouter, for the same reason I wouldn't buy a 21e6 dangle that points everything automatically at a single pool with no option to reconfigure.

I don't think anyone's successfully pushed a Compac to 500MHz yet, but we've gotten decent results above 425 with very top end voltage (one of Novak's small flock of stress test subjects got about 815mV). I think the only way to go higher would be to reduce the top divider resistor, which allows the pot's sweep a greater range. This is the small blank resistor near the pot, which is nominally about 35K; reducing it to 30K takes your pot range from 550-800mV to 615-875mV which should be much higher than you need.

It is a downer it does not allow you to pick pool.  I personally want to be able to send it over to the compac solo club phil has over i pools.   I do hope you can find a way to mod the R1 to allow pool choice.

The R1 shipping is also crazy.  To US it costs over half of the device cost I believe.   Which is an insane ratio.

Looks like RPI will remain king for compacs as far as little controllers.

.......

My understanding is that neither the "21 Inc Bitcoin Computer" nor the "Antminer R1" are released and shipping yet. While the prevailing sentiment is that they will both largely be "closed" in terms of configuration, how does anybody KNOW this?

It seems until we get actual documents, and/or a shipping product, it's kinda speculative as to what can and can't be done. I don't have a specific interest in either product, but it seems a bit premature to decide what they can and can't do at this time.

Even if it is closed I forsee people getting around R1's limitations.  Look at phone rooting/jailbreaking.   And I think it will not be horribly hard to modify their router since in past their miners allowed 3rd party firmware. (For example smit's firmware).  So likely a firmware will do it.

So I don't know who but i forsee someone changing some features to more like we would want them.

Do not know why you think we are speculating on the R1? This from the Bitmain Website.

The AntRouter R1 is a wireless networking device containing a bitcoin mining chip. The R1 is preconfigured to mine on AntPool’s solo mode, meaning that as long as the device is powered, you are competing for a chance to solve a block and win about the entire block reward of 25 bitcoins(after deducting the 1% fee).

 Shipping starts from Oct. 8 after receiving full payment.
