It worked fine tonight:

You're still getting 15 minutes a day from my rig on the US west coast, so maybe it is a problem ozcoin. I'm busy tonight, but I'll check it out tomorrow and let you know if I find anything.

You're probably looking at the DHCP client table, which only reports IP addresses that the router assigned. If you assign a static IP, it won't be on that list.


Without any routing information (a default route/gateway), it'll only be able to communicate with the network it's on. So, you should be able to ping your router, but not google.com, without a default route. You'll have to configure a default route to communicate with anything outside of your own network. If you're not sure how to do that, just let it use DHCP instead of setting a static IP.

I'll need 192 chips out of 200 that I ordered. I ordered extra to cover any duds, but if they all work, I'll have 8 extra.

My expectation is that a K64 will have a lower part count that 4 x K16s, making it just a little bit less expensive. That said, if K64 boards aren't ready by the time my chips are delivered, I'll be having 12 x K16s.

Follow up:
I'm not making any progress with the new version. For some reason it doesn't appear to load the same driver for the AM USB sticks. I used to get a /dev/ttyUSB# for each device, but not with this version. lsusb lists the hub and the miners, but cgminer doesn't find anything to mine with. I'm in over my head trying to make the new version work at this point, so I'm giving up for now and rolling back to the prior release.

I think you could replace /opt/minepeon/bin/cgminer with the one you compiled, then modify /usr/lib/systemd/system/cgminer.service with whatever command line options work for you. Finish up with systemctl --system daemon-reload. Then it should just start mining on boot.

It does not. I'll mess with cgminer's config a bit and follow up shortly.

Results: The hub works great. It powers a Raspberry Pi with no backfeed issues. I only have 4 sticks, but I have no doubt the hub would run 7 of them, as I opened it up and found 2x 5V/3A regulators.

I plugged it into my Kill A Watt before work this morning. It was reading about 22 watts even. That's a 12V/12A PSU, USB hub, Raspberry Pi, and 4 USB ASICminers.

The 12V PSU is certainly not running very efficiently at such a low load. I should be able to save a few more watts by using a smaller power supply. I'll find a suitable wall-wart and update. I'll take some measurements on the DC side as well, which might be more useful for those who intend to go solar.

Awesome. =)

You're quite welcome. Have a look at this post for some quick & dirty instructions: https://bitcointalk.org/index.php?topic=195052.msg2300891#msg2300891
Let us know if/when it works, and if you need any help, please don't hesitate to ask.

I saw at least one person over in Arklan's group buy who claims that hub will run 10 sticks. Arklan said he's running 9 sticks in one (he didn't try 10).
I have a fan moving some air over my sticks. I doubt that it's really necessary, but it makes me feel better so I do it anyway.

A Raspberry Pi can do it. It's linux, not android, but it's still an ARM CPU. It's a nice way to keep power consumption as low as possible. Check it out here: https://bitcointalk.org/index.php?topic=137934.0

I'm in for 3 K64s. Ordered 200 chips from SebastianJu. I'll see if he can ship the chips directly to you when the time comes.

mineforeman is working on an update which will make these USB sticks plug & play, but until then, here's how I got minepeon beta 1 working with them now. *There may be a better way, this is just how I did it.

At the command line:
1. type (or copy/paste) Now you're looking at a simple text editor
2. use the down arrow to find the line that starts with "ExecStart=" This is the command that will start bfgminer
3. on that line, use the right arrow to find "bfgminer -S auto"
4. change "-S auto" to "-S /dev/ttyUSB0" for a single miner, or "-S /dev/ttyUSB0 -S /dev/ttyUSB1" etc for multiple sticks
5. press ctrl+x to exit. nano will ask if you want to save your changes, press y.
6. type (Stops cgminer)
7. type (Stops cgminer from starting at boot)
8. type (Makes bfgminer start at boot)
9. type (Starts bfgminer) You should now be mining, use the next steps to check
10. type to display the miner's console interface, check to make sure it's mining
11. hold ctrl and tap a then d to exit back to the prompt without killing bfgminer

If you have any trouble, feel free to PM me. I'll provide as much help as I'm able.

Try the included version of bfgminer. It works for me.

cgminer doesn't want to recognize the USB sticks, but the included version of bfgminer works just fine for now.

Don't worry, it'll work. =)
I only had a few minutes to mess with it between when the mail showed up and when I had to leave for work, but I can confirm that the latest minepeon will run these with bfgminer.
You'll have to tweak the command a little bit, but I can walk you through that. I'll mess with it some more when I have some free time and see if I can get cgminer working as well.

Arklan: It was a pleasure doing business with you.

Hopefully, indeed. I thought about going with a USB 3.0 hub for the extra current as well.
Friedcat said that the sapphire batch draws 500-510mA, so it should be fine, but we shall see.
Either way, I'll post results and power consumption shortly after I get my 4 sticks.
