And you're sure you are hooking them up across different legs? What power supply is it?

Right, because openly stealing is a good business strategy.

Holy SHT that's a lot of coins. One tenth of that much money would be enough to bring a miner to market, chip and all.

I've never seen a Pi that didn't have a micro USB jack for power, but then I'd never seen one before about four years ago. When did they make the change?

I prefer mini USB, hence why I'm using it for signal on the Terminus. Speaking of, my Raspbian setup (the Pi is drawing power from the Terminus) is at 43 hours uptime and going strong. 110GH, 53 watts DC including the controller.

Also if you start referencing pot position with the USB jack at the bottom like has been mentioned several times, everything you read about pot positions will start making sense instead of being exactly wrong.

Cool. I'll get something headed your way soon. The driver isn't optimized for them yet, so stuff like zombie recovery probably won't work right at first until VH makes some updates, but the hardware's all there.

I guess what I meant to say was, that's not an option for everyone, especially if you don't want to mine alts at all. And yes I know you're gonna say "yeah but if you do such and such it gets automatically converted to BTC so it's just like mining BTC via alts" and you know that's something you and I have disagreed on for a long time.

So yeah it's something people can do. But you know I straight-up don't care at all. The discussion right now is pod miners, and a stable Pi controller with config options for basic users.

That said - I'm a bit behind but planning to cook up some proof boards over the weekend. I'd like to send you one to review, if you're game.

Ah yeah, that'll definitely require more voltage. Seconds, like everything else, are tested at 100MHz.

I wouldn't have shipped anything that threw more than 2 errors per hour. What speed are you running it, that you're seeing multiple per second?

Might look into that.

Speaking of, the Minera pi barfed some kernel errors overnight and died. Raspbian is still running like a champ, 18 hours uptime and going. We've got a few weeks before these guys roll out so I'll see about integrating a basic webconfig setup. Luci's a good place to start.

I would guess it's got to do with thermal expansion and contraction. All I know is, back in the Compac days we set up some test sticks running cranked up and they worked just fine for weeks (though quite warm), but after being pulled some of them never worked again. Never had the issue with sticks that weren't run hot so I assume that's what done it. 2Pacs are probably even more susceptible because they've got 2 chips under the same size heatsink, which means potentially twice as much heat trying to dissipate. For super high overclocks I'd recommend finding a more efficient heatsink to reduce the chances of a chip getting cooked.

That's not an option for everyone, especially if you don't want to GPU-mine alts.

I just made a script of the command line in a screen session and dropped a reference in rc.local. Took about ten minutes of various web searches and testing configurations. Something like:

/home/pi/run_cgminer.sh:
screen -dmS run_miner ./vthoang/cgminer/cgminer -o http://solo.ckpool.org -u 1BURGERAX...

rc.local:
su pi -c '/home/pi/run_cgminer.sh &'

That's all from memory so it might not be exact, but the basics. The "su pi" part makes sure the screen session starts with normal user credentials instead of root so you don't have to sudo to find it.

As of right now, both Raspbian and Minera machines are still up and running. Maybe the additional RAM of the Pi3 is good for Minera because it's been up almost 6.5 hours and I don't think I got that kind of uptime out of the old-version-Pi setup I was testing with last week. I moved the SD card straight from one to the other.

Whichever one I think works the best, I'll probably have the image available for download and also have available for sale a Pi and pre-flashed SD card to drop in as a controller. Maybe I'll make both available, if they both wind up being relatively stable. I assume Raspbian would be more stable, but would require basic SSH skills to edit configs and view stats. Which reminds me, I haven't messed with miner.php and API/RPC stuff in a while. Should see about getting that going too.

What's the webconfig stuff Avalon uses? Is that open-source?

No news currently. The last I heard from Bitfury, chips were sold out until around Halloween.

But Bitfury's not the only game in town. We might see a little magic yet.

By the way - got me a couple Pi 3 boards, one running Minera and one with Raspbian Lite. Got Raspbian set up with cgminer running on boot so I can plug them up head-to-head and see if one of them won't lock up and die every couple hours.

Right now I'm not terribly confident about Minera. I'm having a hard time convincing myself that being able to edit the config via webpage is worth dealing with the tons and tons of scripting garbage all over that webpage.

Probably both.

That really depends on how hot you're running them.

Sounds like a question for VH.

No preorders. I don't really like them. Some pre-ordering was necessary in the past when I didn't have enough money on hand to fund an initial batch, but you'll note it wasn't preorders in the traditional (within BTC hardware anyways) sense where your order money was used to fund development. That's unacceptable.

Anyways, 2Pac sales the last several months have made that no longer a problem. As soon as I have all the materials in hand and a robot freed up for a day we're gonna start batching these things out. Resellers I'm sure are going to eat them up, but we'll have individual full-kit sales open as well for low-volume purchases. I plan to make at least 500.

I think we're sold out right now. There's one left in the box but she might have an order pending for that.

I think she's making a list to let people know when we have some more, which likely won't be for at least another 3 weeks.
