No, I think I'll just assume the end user might plug them into something that doesn't suck. Adding on features more-or-less designed to support a single controller is adding an extra cost that's unnecessary for anyone not using that single controller. General-purpose hardware should be general, that's why we're making it USB-tethered with a cgminer driver instead of designing for a specific controller and proprietary implementation.
makes sense.. i guess for now you can try to enable the built in watch dog timer on ther pi itself. if the pi doesnt hard lock it should work if its just cgminer crashing. https://www.domoticz.com/wiki/Setting_up_the_raspberry_pi_watchdogWell, if i knew this earlier, setup would be somewhat cheaper.. i may have to setup my 2 pi's again. |

My toaster is pretty shiny. Also a double-wall wide four-slot with dual digital timers, click-lock pull-out crumb trays and a "bagle" button that only heats the inside elements (which is great for buns too). Be better if it were six-slice (I really like toast) but you know, whatever it's still pretty great.
 Also looks like the Pi locked up on me after a while. All lights were on (no network activity, just solid LEDs), unresponsive on SSH and cgminer wasn't running. Power cycle brought it right back. I'm not too familiar with 'em, really, but is there any kind of watchdog timer to automatically reboot should that happen again? Other than that huccup, the 225MHz sticks have been running great. I should probably have been more thorough with core voltage testing (I basically raised it until I saw no errors in a two-minute sample) because errors are still higher than I'd like (HW 365, A 180K) but actually it's not terrible for what's being done.
the pi's don't have any watchdog, they are just cpu+gpu+ram with io, in my little workshop when my boss setup a pi to be a webserver, he made one with reset/power and RTC and LCD output, iirc it did reset itself when it didn't respond on the I2C when it tried to pull info for the LCD then he switched it out for a simple desktop on the 2nd revision. |

Such a dumb idea to let an online service hold your password. Thanks god for new advancements in this space. www.GetClef.com - passwordless login! Doesnt sound like the best idea either. You are recognized by your fingerprint and then all your passwords are open? Fingerprints of that level can be faked so easily, its nearly funny. You only need to find or get a fingerprint on a glass or something and you already can authenticat as the owner of that fingerprint. I would never put important passwords behind that. fin All you need is a sufficiently high resolution camera and a picture of someones fingertips to get their fingerprint, then from there you can easily reproduce it for scanners using standard office supplies. http://www.theguardian.com/technology/2014/dec/30/hacker-fakes-german-ministers-fingerprints-using-photos-of-her-handsYes, or sellotape, superglue and a fingerprint someone would leave on a flat surface.  Similar to crime scene investigation. So a thieve has every chance he wants. Cutting a finger is not even needed.  going down the finger print lines, mythbusters even worked out a easy way to do it with basic stuff, but they refused to release that information to the public, and it worked with most fingerprint readers. |

Naw, I was in a bit of a hurry to finish up and still get to the post office on time (unfortunately I arrived seconds after closing time) and I think the config defaulted to the BEUSB address on BTCDig that TheRealSteve set up for the erupter contest. I haven't bothered to make an account there but it's handy for testing since the vardiff starts at 2 instead of 128.
If the shop VPN hadn't gotten hosed in a storm-related router crash last week (and I haven't fixed that part of the config yet, whoops) I could log in and change it. But I didn't. Oh well. Maybe tomorrow I'll figure out the issues with the other sticks, hook the hub up to a beefier 5V supply and run all 8 together over the weekend at the 1BURGER address. That'd be 66GH. It's fun to think I could push these to 11GH off about 3.6W, when an AM Blade was top of the line gear just two years ago and took 24 times that power to do slightly less work.
Think I should push them at all? If I can keep 'em cool at 225MHz (what, about 4.5W each?) that's right at 100GH which was a loaded Blade backplane, and even counting the power taken by the fan and the Pi this would still come in at half the draw of a single Blade. Hooray technology!
then good old 500W foot heaters.. i was half tempted to buy an old set of them, someone here in aus is selling them for $100ish for 10 blades, and they a shat on by 8 little hand made sticks! i better keep working on my quantum entangle light based ALU |

im lol'ing on how many people dont understand how lastpass works..
What i know on how it works, is its not storing your passwords in the clear on their servers, its encrypted on your system, you can select how many times it hashes the password, and it hashes each and every password with a random salt, x amount of times you have told it, and then it blobs it into 1 single file, that it stores it online with your account, so when you sigh in on another system, using the main password and log in, it starts decrypting the blob, then once you go to a site it decrypts that file that is assigned to that site.
and just to add to it, they cannot reset your password online.
the hack may have scrapped the blobs for the accounts, but without them brute forcing each blob just to open it, only to find out and then brute forcing each file at who knows how many iterations its been encrypted, only to find that they have to work out which one is your email password.
if you have 2 factor authorisation (like yubikey), and never use your major password for anything website, guess what? you're safe, but just change your major password, for paranoia sake.

changing the VID/PID on them things shouldn't be hard to do, to be USB compliant, you may want to register it? A proper VID registration is not chump change. For something with such a small run, mainly used by techy people, and presuming they don't necessarily want to put a USB logo on the product.. it's just not worth it. Thus my earlier suggestion of instead getting a PID from a PID vendor, or using the VID of a defunct company. Plenty of articles on the internet about the pros/cons of doing so in terms of potential technical issues, whether or not entities have a right to sell the PIDs they do, and legal considerations. Eh, i didn't see the costs, yeah, ignore my statement.. if you are using them cp2*** chips, please use ESD protection on it [...] if not you could move onto the more bells and whistles, yet more expensive, "FT232R"? and call it a day? While ESD diodes on the CP2102 inputs is nice (AntMiner U1/U2, bi•fury use 'm), I've not had any on other products that didn't have them fail. But that's anecdotal and there's plenty others who do swear there's issues. If an alternative were to be chosen, though, FTDI wouldn't really be my first choice for the same reason that Prolific wouldn't be my first choice. There's always MCP and wCH. If anything, I'd use a CP2103 and make use of the 4xGPIO.. but that doesn't negate ESD concerns well you should know my religious stance on esd protection now, ive said it enough times.. |

Yep, the Icarus driver is pretty much a disaster at this point, with all the different little tricks required to detect from a couple dozen different machines using the same interface. We're going to try to write our own driver, and probably do something with the CP2102's manufacturer and device codes for ready identification.
changing the VID/PID on them things shouldn't be hard to do, to be USB compliant, you may want to register it? as i have mentioned before, if you are using them cp2*** chips, please use ESD protection on it (if you haven't done it yet, also people asking about it here maybe good info in there?) if not you could move onto the more bells and whistles, yet more expensive, "FT232R"? and call it a day? Alright, looks like skinny it is. The PCB dimensions of the Compac are 1" by 2.5"; the Amita will probably be more like 1.3" by 4.1". The extra height is there to accommodate the doubled heatsinks, since there's one 25x40mm heatsink per chip. It'll look pretty much just like the Compac extended upward with a second sink above the first.
I'm probably gonna cut out of here in about two hours (making this an 8.5 hour day already) so let's see if I can't get the Amita PCB done in that amount of time.
Also, I'm going to give our tardy debtors until about Friday to get things ironed out with us (I expected it to be taken care of last Tuesday) before I think about short-term-borrowing some coin to cover the chip order I expected to have paid last week. So don't worry about it quite yet.
i gotta find dimensions of them 18 chip board (i believe thats the one getting made to fit the U1 yes?), im wondering if i could retrofit new-r-box sinks to them.. |

Not until I can purchase my very own mac computer, because they do not allow development on anything but their operating system.
And it's for this reason (among others) that I would never support Apple or any of their products. I like to use Flash just because Steve Jobs hated it so much. it's worse than that  The Apple OS license requires you buy a computer from apple to run the OS. The license means you can't even buy OSX and run it in a VM. ... even though an apple is just an over priced intel PC ... running BSD (which isn't all that different to Linux) people love their walled garden, I have no choice but to support people that have apple products, so I have to know all the ins and outs of the os and products. without doing a hackintosh or spending $2k, i know little other then what i can google up, which is just enough, for now. ... and that is only 5-10% of my customers and 1% use some flavour of linux. |

I also prefer carburetors to EFI.
I'm surprised, EFI is way more tunable and customizable than carbs, especially when you get into writing your own engine management programs like I have. I've contributed much of the tune to my Mustang, including stuff other than the usual air/fuel and timing, such as the mass air meter tables and transmission shift graphs/algorithms. Way more fun than turning screws on a carb! 3 screws, tweak them by half a turn, car is a different beast.. i have it atm, lean to the point of white spark-plugs with cruising, dumping the fuel when the secondries open up, beats a modern 3L V6, with a whezzy 1.3L.. getting around 30mpg city, or 8L/100KM much more easer then trying to add 1000 odd points into a throttle/fuel/air map do a few aero mods, cold air intake (just got a filter sitting on top of the motor), and add manual tans, i could pull 40, maybe 50mpg.. ..anyway The sticks will never have auto tuning (for voltage control). The required overhead is stupid for a one-stick miner.
The 18-board will not be strictly auto-tuning. There's no reason to cripple a thing in software when the option for "more control" is already there. The primary reason I got into bitcoin mining hardware to begin with was because I liked messing with the hardware, so why would I give you guys something you can't play with to the max?
I also prefer carburetors to EFI.
going like the old block eruptor blade style? with its voltage control via small pot? |

...I wonder when the other three guys are gonna start reporting opinions?
so far there has been CrazyGuy and philipma1957, you pinged the other guys? on that note, CrazyGuy, hows yours been going? |
|

|
|
auto-tuning is nice and all, but i do like to muck around doing my own manual tuning.. but im the type to still run a carburettor over electric-injectors..
leave the little buggers for the manual tuning, the 18-chip boards with auto, it should satisfy most people

Since this is using the U3 stuff in cgminer, you may want to use cgminer 4.9.0. 4.9.1 does not recognize the U3, it's a known bug, so don't know if that will affect this stick. You probably also want to add --suggest-diff 1 to your .bat file so that your stick starts at a reasonable pool diff. If it enumerated as a COM port, you need to install the WinUSB driver for hotplug support and such ( Zadig) which will allow cgminer to detect it natively. Is there a way to do this without using Zadig? I have a computer that refuses to complete the Zadig installation, so I need to find another way to do what Zadig does. could do a 'buntu run, need to give permissions to the com port though, 0224 hours here, so not up to pulling info right now, if you need it, pm me, i'll look for it about 0900 |

0.32W/GH is damned impressive/amazing.
Fricking incredible.
and thats off a chip that you see been quoted as 0.5~0.6W/GH elsewhere... don't hold me to them numbers though, not fact-check myself here |

Oh, Mr Sidehack, with your usb miner design, you're using the CP2102 yes? do you have esd/power spike protection on the data lines from the USB to the chip? (i think some smd capacitors from each data line to earth should do it i have to double check the data sheet)
just a thought, since I've has nothing but bad luck with things that run from CP2102s (hand full of usb block eruptors, a zues miner, my "new R-box's" all with fried Silabs chips)
I have had a lot of block eruptors in the hundreds very few failed. My 100gh r-boxes all worked well. Do you have power supply issues? Do you overclock? Did you fan cool the usb sticks? floating ground to earthed ground (psu connected devices + laptop = esd off laptop to psu via whatever means) i'll PM you the full details if you want, im not going to hijack this thread about it. |

So that last block we just found was a nail biter ... 23 minutes of waiting to see who'd confirm the block - ours or Bitfury ... And we won the orphan race Another good low diff block 29% Thants it, lemmie rent some hashes! imma spend what i have left to get back in... then you watch, +500% when i jump back in |
|
|
|
Block party! Now why couldn't today be Friday?  Wow, nice 29% block. My last payment was double what I'd been receiving, so I guess this is a good way to go out for the summer. buddy.. i need some heaters here for this winter, lend me your miners |

Seems like Eligius pool likes to hide the truth They deleted my reply to their libellous post about me in their thread (and send their miners blocks with empty transactions to speed up their slow pool software ...) This just shows his ignorance. Empty blocks minimise your stale shares. Eligius (and probably most cluefully operated pools) send them as soon as a new block is found, so that you can begin mining immediately. This is also followed up with an updated block full of transactions that miners can begin working on as soon as they receive it. If your internet connection is 10 Gbps, the empty block might waste a few bytes of bandwidth and you'll get the full block immediately to begin working on. If your internet connection isn't so fast, you'll begin working on the empty block, then transition to the full one as soon as you finish receiving it. Of course, this is assuming you're using optimised software like BFGMiner. It's quite possible kano's cgminer is buggy in this regard and will mine empty blocks even after it receives the full one - I don't know, not my concern. Well since all the other points have be proven not to be lies by your and anth0ny's replies, I'll just point out about this one. Anyone need only check the blockchain blocks to see blocks with no transactions in them. Pools using the eloipool software send out empty blocks ... and yes that includes antpool. Empty blocks minimise your stale shares. So do miners really think that a tiny number of stale shares is more important than confirming transactions in the blockchain? Well, you could always avoid it by using ckpool, that doesn't have this design flaw. ... and of course he infers a lie about cgminer - but wont outright say it - because he knows it isn't correct. ... and the stratum code in the cgminer clone was copied from cgminer - because luke posted on the forum that stratum was difficult to write. But Kano, their pool is perfect! the mining software is made to the pool, nothing could go wrong! unlike this buggy ckpool software they cant get working, it doesn't talk properly to their mining software! so buggy, so useless! now start mining empty blocks! make more hashrate numbers! |

I just need to work out how to control luck It's there in the code somewhere, keep digging!  Well...What the hell....try a restart @48hr...can't hurt? Oh, heck, it's all luck! No 'Magic Mike'. Bawaaaha. All i can say is Quantum calculations... My quantum calculations are going great, they are simultaneously a complete success and I have not started them. I would let you observe my work, but... Yeah, i know.. i could look at it backwards when its moving though, that's if i can follow them electrons passing over the bits. the problem is, every time you hit a block, and look at it, it never happened. i blame kano looking at the logs all the time. or everyone else for that matter, looking at their logs. you'd be a millionaire by now. you know, our understanding of quantum mechanics, it in a quantum state. we know what happens, but we know nothing about it! |
