As an update - D750 boards are back in stock. We're still manufacturing so there might be a day or two delay in shipping an order but all parts are in.

We are, unfortunately, almost out of PSUs (probably less than 10 available right now) but I should be restocking this weekend.

DPS2K stuff is still in stock for the time being.

I'm very much in favor of reusing existing chassis with updated boards. Saves home miners a ton on shipping costs and also saves us having to do the mechanical design and contract out heatsink manufacture and stuff. All in all it means a less expensive end product, and who doesn't like that?

The holdup on the Chuckwagon right now is efficiency and current monitoring. I've got parts inbound for measuring output current, which I can use that current measurement to change up the buck drive a bit to increase low-end efficiency, and then change it up again to increase high-end efficiency. Once that works on the existing test board, we can throw together several boards and test a multiphase interleaved design. Hopefully it doesn't take too long to get it ironed out. But we ended up working half the weekend and all day yesterday and half of today making D750 boards to get caught up on orders, and we'll have to do it again probably Friday, so no guarantees. But the Chuckwagon is priority, definitely to be finished before any TypeZero boards are prototyped and well before we think about a Prisma refit.

Using emoticons in a reply is slightly unprofessional, but this forum isn't exactly a formal place. But when your entire reply to a valid question a paying customer has about the machines he purchased is a series of emoticons, there's room to complain. It's basically dismissing the question offhand (and in a manner which could be seen as condescending), which is rude.
5324  Bitcoin / Mining speculation / Re: Next consumer model miner on: March 18, 2015, 04:08:24 AM
So someone working on the wiki just asked for BM1384 pictures. Guess I'll have to do that tomorrow then. Also I think we have enough info to start work on a test single-chip board to start getting software ironed out. After that it's only a few stages to a test string/matrix and a working full design. Tomorrow will be a miner day (tentatively named the TypeZero) but after that I'll have to get back to the inline regulator project (tentatively named the Chuckwagon) because the prototype's been overdue for weeks because of various "this doesn't work, what the heck", "where did our R&D budget go" and "being really busy sucks" type problems. But progress is being made.

One of these days I'll start an actual dev thread for the TypeZero, and one of these days I'll have a Chuckwagon prototype for Philipma to play with. Only been promising him one since about Christmas.

But if what we want to do is possible (and affordable, and we get enough money to actually make a batch) we'd be looking at what amounts to an S1 Upgrade kit to the tune of 1.3TH <600W, which can software-underclock/volt (using cgminer flags) to a 600GH ~160W miner. Or the boards can be run individually as ~300GH 150W units clockable down to 150GH <50W and run off a brick, which if you add a quiet 120mm fan could make a pretty decent Jalapeno-formfactor desk miner. Boards would be USB-connected to a controller, so each "S1" would require a 4-port hub but several should run off one host (Pi or whatever). That's the goal, anyway.

If we were able to pull it off, how many folks would be interested in a Prisma chassis refit? I'd shoot for the same power draw (~1KW) at stock settings, so if it scaled directly with the current idea's expected limits you'd have a range from 2.4TH@1KW to 1.1TH@300W.
5325  Bitcoin / Hardware / Re: Beginner, choosing PSUs for BFL Monarchs on: March 18, 2015, 03:49:56 AM
Yeah, that is an option. I'm almost out of Dell 750W PSUs until I restock over the weekend, but we're manufacturing boards this week. If you only need two PCIe per PSU I could get you three 2-cable 750W kits for $44 apiece and $15 shipping (cables are 18" 16AWG 6-pins).
A DPS2000 kit with 6 cables would be $100 flat plus $15 shipping and you'd need to conjure up fans and a C19 power cord.

Just throwing that out there. I can only advise on server PSUs, since that's the only thing I've ran miners off of since I started mining going on two years ago. Listen to the other guys for ATX options.

So, your purchase isn't actually a sale?

Wait a minute. Okay, I'm forgetting one important thing. They're pre-selling stock they won't be shipping for another couple weeks. If they were shipping orders as they came in you'd have no grounds for compensation. But yeah, since they won't be shipping ANY orders until later, and a $320 order will ship at the same time as a $419 order and a $369 order and all coming from the same batch, yeah that's a bit screwy and they oughtta do something about it.

Apologies for your spike in blood pressure, good sir.

What main street do you shop on? Because I gotta agree with the guy what with the gas station example, that's not how it works literally everywhere I shop.

When you bought at $419, did you buy knowing you'd need the additional $50 in hardware? I know it's pretty much pointless to argue on the internet because everyone is always right and always wrong simultaneously, but you gotta admit you did agree to buy them at the list price. It would be mighty friendly of Bitmain to make good to the people that bought at the exhorbitant price instead of the slightly less exhorbitant price, and apparently they feel they're doing so by offering coupons. That's technically more than they're required to do. The only thing they're required to do is ship you the stuff you ordered.

And remember the first rule of bitcoin - only invest money you're willing to lose.

I've never seen someone get a price difference refund that wasn't the vendor deciding to be nice. It's not required. You agreed to buy at $419 so they charge you $419. The guy having issues when he bought at $320 and they're asking him to resubmit his sale at the $369 price has the same problem - he's unwilling to purchase at $369 because they agreed to sell at $320. Just like he shouldn't be asked to pay the difference for their price change after his purchase, you shouldn't be asking to pay the (negative) difference for their price change after your purchase. All Bitmain is required to do is honor the transaction as it was made. I agree the price sucks balls but it's the price both parties agreed to.

If anyone except Dogie had applied the same logic, would you have reacted in the same way? Hating on someone for occasionally being right even if it hurts your feelings is stupid.

Please note that he defended them a little over ONE FULL YEAR ago. It's a pretty different story now. Stop digging up ridiculously old threads.
5330  Bitcoin / Hardware / Re: ANTMINER S5: 1155GH(+OverClock Potential), In Stock $0.319/GH & 0.51W/GH on: March 17, 2015, 01:51:57 PM
First, shut up. Stop hanging on every little word one guy says in the hopes you can call him out on insignificant crap, and try to actually help people when they have questions instead. Say something productive, or at least germane to the conversation.

Second, coincidence or not, what matters is that Bitmain's warranty office still exists and actually responds to problems in a timely manner. Maybe they put the office next to Minersource because it's roughly centrally located on the continent and near to the largest distributor on the continent, but that doesn't matter anymore with Minersource moved off and gone silent. As long as they're still fulfilling the needs of the people, who cares who used to be in the office next door?

Email Janet (Janet.Zhao@bitmain.com) about chip purchases. She's dealt with me professionally so far, and I don't think I've seen any emoticons. Just actual answers to questions.

Rent on my ground-level one-bedroom apartment with off-street parking in a friendly neighborhood is less than 1.5BTC monthly. I moved here from a 3-bedroom two story house with a half-finished basement and 15x45' workroom, fireplace and hardwood floors renting at 3BTC monthly.
For 1500BTC I could buy 40 acres and build a sweet two-story with a basement and two-car garage and probably a 40x60 outbuilding. And a few cows to eat.
Wherever you're living right now, I'm gonna stay far away from there. Midwest is where it's at, man. Even in town the municipal electric rate is less than 9c/KWh all-in.
5333  Economy / Securities / Re: How do you invest your bitcoin? on: March 17, 2015, 04:38:57 AM
Consider that for every coin gleaned from a gambling site, someone else lost at least one coin to that gambling site. So sure, play and walk away a winner but remember some poor chump is walking away a loser. That's the nature of gambling. It's the same with mining altcoins; the only winners are the guys that leave in time to walk away with whatever was put in by everyone else.

The only business I've ever invested in, that wasn't just purchasing hardware, is my own. It's not that I don't trust anyone else to not screw me over, it's just I don't like investing because I'd much rather work for a living than sit back and watch someone else pay me to let them work. It's partially for that reason that we don't take in any investment money from anyone else - our only revenue stream is the direct sale of goods (either manufactured or value-added, we will not profit from middlemanning) and services. Another good reason being, when someone owns a share of my work, someone has paid me for the right to influence decisions even if he's not actually doing any work himself and that's both stupid and a recipe for someone getting screwed. Mining bitcoins directly, and selling goods and services within the bitcoin economy, has been my full-time income for a little over a year now.

I take offense to the consideration that there are zero honest businesses in the bitcoin economy. It's close to zero, but not zero yet.

Every year Detroit beats out St Louis for America's Most Dangerous City, and as a Missourian (but 100 miles from STL) every year I'm not sure if I should be disappointed or not.

BE300 could do it (if it existed) but I don't think it's possible with the BM1384. Yes, there'd have to be a new chip to get past 4TH/KW even board-level, let alone from the wall.

I had one behaving similarly - every few reboots it would hash for a few minutes and then stop hashing while disappearing from the network. Ping still worked, I think, but no webconfig loaded. Figured it was bad code so I updated the firmware and it's been running without issue for a week and some.

They don't actually require 5V. There's an internal switching regulator so it'll take up to 12. Most of the ones in my hosting ran on 12V.

I was pissed at the president when he took a couple weeks to campaign internationally when he ran the first time in 2007. Since, you know, foreign leaders are supposed to vote in US elections.

Sorry, today's primarily a "manufacturing D750 boards" day so we can ship orders out. I probably won't even be able to play with power stuff for the board until Wednesday at the earliest, and I'm not sure how long it'll be for Novak to have even a one-chip test board to play with code.
5340  Bitcoin / Mining speculation / Re: Next consumer model miner on: March 16, 2015, 06:28:48 PM
Why? It's just a little plastic bag with a cut-tape strip of chips in it and some labels written in Chinese. Maybe once we have a sample board with one or two chips on it working I'll have something worth photographing.
