GekkoScience Compac BM1384 Stickminer Official Support Thread

Yeah, it was more a comment to toptek: "I think why they and you get that error is doesn't it all comes off one of sides server right now ... maybe no support at all on there server for openwrt" All we have is the source code, and any libraries to compile for a particular OS/instruction set are completely independent of the code for the program itself.

I really can't help much past that. Novak's the nix guru, I'm the hardware guy. I know enough to maintain my own machines most of the time, but that's about it these days.

[toptek]

We only host the source. Dependencies are the responsibility of the user.

yeah i understand that.. im getting the openwrt build from git so it should have everything.. im thinking its something tho, maybe a CC path or something i am missing.

most of the time so far that Ive seen with forks it is a path issue with openwrt, it may be as simple as a line in the opkg.conf but I'm sure you know that .

it's cool its worded wrong in  there some place !! im well a ware that was why .   .doesn't doesn't  belong my bad .but thanks for pointing that out.

Yeah, looks like you know more about it than I do. Keep on keepin' on, sir.

I am using a USB hub to run some miners.  It fails when I put 3 in and is working with two. The power supply is 12VDC @ 7.5a.  Should do 90w.. only drawing 16ish.

At stock frequency ?

I am so excited about this, I have my hub and pi2 ready to go and just waiting for my stick miner. Downloaded the custom minera and have a hub ready to go, what frequency is the best for 24/7 no shutdown ? I can add a usb fan if need be but I plan on actually making a usb 24/7 miner. I am a home miner and I turn all my miners off during the day this happens to be my lotto miner (so I can switch other miners to pools) and keep it on 24/7 while adding more and more sticks while being away. I am going to keep it on a metal rack but I need to make sure it can't get anywhere near dangerous.

Thanks!

Hi, I've been running 2 sticks for well over a week now at stock voltage and 300MHz frequency with very few hardware errors ( 1 or 2 in 24 hours ). They are running on a USB 3.0 powered hub and have an arctic USB fan for cooling. I'm getting 16GH per stick average speed. My best share so far has been 9.4M .

P.S. I cant wait for my other 3 to turn up and join the party! .

I know these will never find a block but its been fun tinkering with them and the software. It brings back good memories .

most of the time so far that Ive seen with forks it is a path issue with openwrt, it may be as simple as a line in the opkg.conf but I'm sure you know that .

so far ive got it to ./configure but when i try to make it says libusb-1.0.so: could not read symbols: File in wrong format

i searched google and it seems to pop up alot..

i am recompiling the openwrt now with more options.. hopefully i can get this working.

Did the hub come with a 12V 7.5A brick, or did you add that yourself? Any hub taking in 12V has an internal regulator that's going to have its own rating. What's it good for?

[buckrogers]

How hot do they seem to get running at the 281 for a period of time?   It seems like they would get kinda hot.

Thanks for sharing nice to see it.

If you have a good fan you can do freq 350.  here are 4 sticks at freq 200

these don't need the fan



notice the stud hub and both bridge type and y-cable for plenty of power in the picture below:

the y-cables seem to work well up to freq 300

Hi were did you pick up those bridge type connectors (not the Y cables)  thanks!

After nearly 51 days of continuous uptime, my Minera/Gekko RPi fell over. I couldn't access the web GUI or talk to it via SSH. So I power cycled the rig and it came right back up.

I'll take a look at the logs to see what happened. But my suspicion is that I'm running out of time on the SD card. This RPi has been running continuously for almost two years.

The take away is just how reliable the compac and cgminer-gekko are with almost 2 months of solid uptime. If the RPi had not fallen over, I'm sure that cgminer-gekko would still be running.

Very impressive hardware and software.

I am curios about two things:

1. what is that little board compacs on the left are connected to before going into the hub?
2. the DROK is connected to other plugs. I thought that you have to connect compac to DROK, then DROK to hub in order to measure. Am I wrong about it?

thanks

I am curios about two things:

1. what is that little board compacs on the left are connected to before going into the hub? can't buy it anymore.  it is a y-cable in board form and it was built to fit those hubs.



2. the DROK is connected to other plugs. I thought that you have to connect compac to DROK, then DROK to hub in order to measure. Am I wrong about it?


I was reading my port voltages not amps  I wanted to know how much the power supply drops.











thanks

so 2 things:

1: What is the way to test the actual Amps per port on a USB Hub?  I heard it needs a load to see something? I see people using the USB V/A digital display unit, but dont see how you could see the Amp per port? can you simply plug it into each port? I heard not...can someone explain please?

2: If they dont make that hardware bridge anymore, and you want to use Y cables to take 500ma from 2 ports to make 1A, then what would you use to stand them upright if they are to be cooled properly etc?


It might be cool if someone designed a new form of the hardware bridge that is 'adjustable' to 'side by side' or on 'in front of another' ports.

unsure how that would work? possible sliding connectors on the base?  interesting thought, and a possible market?

thanks!

Build something !

(this is a prototype until I get a decent USB hub)



Final version will have the sticks horizontal and plugged in a USB doctor.

best place to purchase the y cables?

and also how to test amps per port?

It came with a 12V  7.5A brick.  I found the 12VDC odd as well.. the usb is rated for 12 VDC in, it's running 3 at 200mhz.



I'll check the voltage on the miners.

Ebay for Y cables

Drok tester or USB doctor will give you Amp, but you need load... and you need to simultaneously test several ports you plan to use to check for Amp balancing...

So there is no way of telling besides the sticker on the bottom of the hub how to test each individual ports max capacity? If you put a load on 1 of 10 ports, you can see the Amps of that specific usb stick .....no? 

How will that tell you what the max Amps are though for that port?

I'm asking because I bought that 10 port us 2.0 hub which has a 60 watt PSU, and the description claimed to do 1Amp per port or more, but on the bottom in chinese it said something about usb: 500ma lol

So without purchasing a specific USB hub that states on the unit it can handle 1A or more per port, how would you test a generic USB 2.0 or 3.0 Hub for that matter to see what the max A per port can be.

Theoretically the one i have at 60watts feeding it should be able to ahndle 1A per port, but the actaul usb port may be configured to max ut at 500ma, you see what im saying?

thanks!
