Now technically you should be able to hook a USB to UART converter right to the hashboard. You won't have temp sensing if you do that; the temp sensor runs through separate lines. There also probably doesn't exist any driver code to actually get work to the boards. But it should be possible if that existed.

Yeah me too. I've had one international package that needed tracked down, but have had no problems with domestics. I don't put additional insurance on domestic deliveries unless the buyer requires it.

There's really nothing else I can do for you right now, but if you give me a bit of time and it still isn't resolved by the post office I'll see what I can do about making it up with other goods and services.

Yeah, I don't miss that. The worst days when I worked at a place that took walk-in customers was when I had to deal with walk-in customers. One day in particular, the guy up front (boss and owner of the business) was hiding upstairs with the secretary (fresh out of high school and 14 years his junior) doing who knows what so I was the only person actually working until early afternoon. Which was great since it was an unusually busy day for walk-ins, and especially great when people came in or called specifically looking for him, because I couldn't give them a good excuse and might have gotten fired if I told 'em he was too busy stickin' it to his barely-legal and fairly naive girlfriend in the back room to actually do his job. I told him the next time that happened I was just gonna lock the doors and turn the lights off so if he wanted any kind of revenue from the entire front half of his business he needed to do his job and let me do mine.

As a happy epilogue, the owner closed the doors the day after she quit, then she kicked him to the curb for being a douchebag and last year got married to a decent fellow. Boss might be dead in a ditch somewhere for all I know, which is okay. He doesn't owe me money anymore. And now I have no boss and no walk-in customers asking me stupid questions all the time, so that's pretty great. And dudes like CrazyGuy and Holyscott are eating most of the annoying customer coefficient, which is even better.

Yeah, I had enough of idiot customers when I did refurb for two years. That kinda burned me out on being nice to people. The guy who left me a negative feedback because he was dissatisfied with the model he chose, and then left a positive review of it in the listing saying the specific object he bought from me was just fine - stupid. The person who left a neutral feedback for a sale which was cancelled before shipment, probably not realizing that neutral feedbacks still hurt the seller rating and it's foolish to leave feedback for a transaction which, with a bit better planning on her part, wouldn't have even happened - stupid. The guy who emailed me three years after he bought something, because it stopped working right within a couple weeks and instead of telling me about it within the warranty period, he spent a year determining the problem was not his GPU, a year sidelining it, and a year apparently with his thumb up his butt, then complained that if I didn't make things right he'd, as some kind of DJ (who also works in IT, as if telling me this would explain his technical ineptitude), slam the side of my business which hadn't existed for almost two years to his mass following of jackoff teenagers and make me rue the day - stupid. And let's not forget the minimum three customers per week who submitted below-cost single-unit offers on eBay despite the listing saying, in big letters near the top, that I was already selling at minimum margin, the single-unit price is not negotiable, and best offers will only be considered as a means of giving shipping discounts for multiple-unit orders. And then all three of those idiots counter-offering my well-justified outright denial. Idiots. But my personal favorite has to be the jerk who bought a monitor, asked me for a speaker bar as well, sent his ten bucks to the eBay internal customer communications email pseudo-address (despite PayPal giving a warning, when this happens, that "you are deliberately sending money to an account which does not exist, continue anyway?") instead of where I told him to send it, didn't say a word to me about it, and then filed a claim with eBay when he didn't receive his speaker bar (because I don't ship things that aren't paid for) that the item received was not as advertised - despite having received exactly what was in the listing and side deals aren't covered under eBay buyer protection especially when the customer botches them. That one took me most of a week to get the guy to pull his head out of his butt and figure out what he'd done wrong. So yeah, I give up. I really like the idea of getting stuff to people without a lot of middlemen and markup, but I really don't have the patience to deal with cheapskates, jackasses and the wilfully ignorant.

Turns out today's offender was buying a bitshopper stick from Amazon Germany, and somehow tracked me down (via multiple hops) through my website from that listing instead of, you know, asking the actual seller which can be done from the listing page directly. I love it when people do extra work for which the only productive aim seems to be annoying everyone involved.

I encourage anyone who might be having issues to first look through the first couple pages of this support thread, try the search bar to see if info is posted by others about the same problem you're having, and then if you still can't find an answer ask me directly but be prepared to give detailed information, the acquisition of which might actually require you to learn some new things. And then if we can't get it going I'll tell you to send it back for repairs, and what the process for that is. Don't just start mailing me broken stuff. Unless I know it's coming and who it's from and why, I'll assume it's a birthday present and you won't get it back.

But yeah, the other day I fixed three sticks. One had a bad ASIC, one had a manufacturing defect (whoops), and three (from the same guy) looked like they had been overvolted on the USB jack which cooked a USB chip, two buck drivers and an ASIC. His was either the bad ASIC or the manufacture defect, but I'm betting it was the bad ASIC since the other one was actually a first-run (V0.5) stick and the part in question has been removed in the current batch (V0.6) design.

I've got some running on DPS1200 on 208V, no problem. Not sure offhand which batches they are, but I tested a board prototype for a week with no issues on one of the 1293W models. I really like how Bitmain changed the design of the miner to make it cheaper to manufacture and more expensive to own and operate.

To whoever put up some Compacs on Amazon and then gave my personal email address to a customer so he could spam me with "I'm an idiot, please hold my hand" help requests", from multiple email addresses, with read receipts - screw you, seriously.

Also to the person who put these down on an Amazon listing as imported from China, screw you too. Unless you're the same guy, in which case screw you forever. Don't expect any help from me next time you want anything.

Is that on a standard 8-pin PCIe cable? The standard only dictates 2 power and 2 ground for a 6 pin, but 8-pin mandates 3 power and 3 ground. Any good PSU would have all 3 hot. You saying the PSU provided with that miner only had two live 12V wires on an 8-pin (or 6+2, whatever)?

I dialed in on it a year ago - S1 chassis.

$700 a month? That'd be nice. I haven't had a power bill that low in a year and a half.

Jstefanop's scrypt stick is probably your best bet for litecoin mining. I'm not sure on availability, but I believe CrazyGuy (asicpuppy.com) and holyscott (holybitcoin.com) have some if you can't get 'em from the manufacturer.

Well, the manufacturer sells them for $25. Everyone else has the added costs of shipping, and advertising, and some necessary markup to cover their own overhead. Lucky there are no additional middlemen between me and HolyBitcoin and CrazyGuy and such, or prices would be even worse. Stupid middlemen.

I've got a nice metal-case Dell-branded 24 port 10/100 that kicked out about half the ports in the last year. It might have dropped all of them by now, I don't know. It's a big paperweight now.

Yeah, those Netgear ProSafe switches are nice. I bought a 10-port gigabit in I think 2009, been in constant use without a hitch since then. If I was setting up any kind of permanent network (and had a decent budget) that's what I'd get. I bought a bucket of the cheap switches for hosting because I would need a bucket of them (I have about 20 customers now) and stuff's always moving around and miners are pretty low-demand. The core of the hosting network is a 24-port managed Cicso that's at least a decade old; after swapping some bad caps on the power board it's been working fine.

I was planning on having them rolled out already, but one of my batch anchor customers still hasn't paid an invoice I expected to see in January which held things up quite a bit. The original plan was to be rolling in November. Being broke all the time sucks. When Minersource evaporated a year ago, I got hosed out of some work I was banking on (already bringing in materials for it, seriously screw Matt Carson forever), which kept me from being able to do my hosting expansion as planned, but I had already promised to my customers the rate decrease which it would have allowed, so I pretty much lost out on not just the revenue from that job but another $1-1.5K per month from last March through February of this year. So, pretty much everything I wanted to do in the last year (stick miners excepted, fortunately, mostly thanks to some work Novak brought in) has either been dropped entirely or way behind schedule, which is why we didn't have 4K boards and DPS800/1200 boards at least eight months ago. I had a DPS8/12 prototype built in December 2013.

I think if the miner project takes off, I might get out of PSU boards entirely. Which kinda sucks since we basically started that market.

I hope I get all my 800/1200 boards built before you steal the market.

I've got a bunch of tplink 10/100 switches all over my hosting, zero issues in a year and a half. Got 'em on eBay for abut $14 apiece.

You'd want a switch.

Oh yeah, also chig volunteered to help with the coding. So hopefully that need is met.

At least according to those quotes, it looks like we agree on comms topology.

And like I said, there should still be plenty of code space for the not-a-whole-lot I intend to do on this micro. It's not gonna be like an AM Blade or Cube where I have an ethernet stack and stratum implementation built in. If there's enough RAM to buffer USB packets that get relayed out to the bus, it should be fine.
