1  Economy / Computer hardware / Garage cleanup - Server PSUs, PDUs, Older bitcoin miners on: March 19, 2017, 10:33:50 PM
Cleaning up my garage as I'm moving soon, and really don't feel like lugging all this stuff with me. Make me an offer, everything ships from Saskatoon Canada.

PDUs
Four Advocent PM10i-30A 10 port PDUs


Each one has two 15A breakers, and can be remotely controlled to turn on and off individual ports

Also, there's a random uncontrolled 12 port PDU

Server PSUs
Nine Tyco 440W PSU


Also include eight connectors that terminate in six positive and 6 negative wires, originally used for Antminer S1s.

Four HP HSTNS-PA01 1300W power supplies


Each one terminates in four 6-pin Minifit Jr. connectors

Six HP 2400W blade server PSUs



Each one terminates in eight 6-pin Minifit Jr. connectors

One Delta DPS-1300BB


Terminates in six 6-pin+2 Minifit Jr. connectors

Bitcoin Mining Hardware
2 Bitmain S5 and 1 Spoondoolies SP20

I believe one hashing board on each still works, though they haven't been used in a year.


1 Bitmain S2 - No PSU
1 Cointerra Terraminer - Never powered on
1 Hashfast 6 board mine - Can't remember what they called it

Includes two Seasonic X800 PSUs, and the six H80 equivalent AOI liquid coolers


All this stuff is going to be heavy and likely expensive to ship, so it likely makes the most sense to ship in lots. Make me offers, while I don't want to give it away I also don't really want to move it to my new place.
2  Economy / Digital goods / Ashes of the Singularity Download Codes -Sold- on: March 23, 2016, 03:09:01 PM
I bought a few GPUs and picked up 5 of these. Four are still in AMDRewards form, while one is a steam key.
0.05BTC each.

About This Game
Take command of the resources of an entire world to build up massive armies, research new technologies and annihilate all those who stand in your way in this new, massive-scale real-time strategy game.

With the unparalleled power of the world's first native 64-bit real-time strategy game engine, Ashes of the Singularity allows for maps of unprecedented size and detail.

Over the course of your war, you will construct thousands of units that have details that are normally reserved for games with only a few active units. Huge, kilometer-long Dreadnoughts can have a half dozen turrets, each with their own firing solutions. Smaller units will intelligently target enemies based on true line of sight physics. That's right, every unit's vision is based on line of sight instead of radial fog of war.

While Ashes has a strong multiplayer feature set, it includes what is arguably the most sophisticated AI engine ever devised for a real-time strategy game. Ashes of the Singularity requires a minimum of 4-cores on your CPU. In exchange, you get an AI that can create complex strategies and plays by the same rules as you do, providing a level of challenge never before seen in a single-player RTS.

Compete in ranked games against strangers or set up custom, un-ranked competitive or cooperative games with friends. A worldwide ranking system lets players find where they stand in comparison to others.

Games are won or lost based on your strategy, not how fast you can click. Deciding what technologies to research, where to send armies, how to manage your economy, and what units to construct are critical.

As the conqueror of an entire world, you will be battling on multiple fronts with multiple armies. Scouting your opponent's strategy, determining their priorities, tracking where they are, and capturing strategically vital resources will lead to victory.

3  Bitcoin / Armory / Two blockchains with Armory on: February 21, 2015, 10:13:31 PM
Sorry if this is a common question, some basic google and forum searching didn't turn up much.

I've recently tried using armory, and am enjoying it so far other than one thing. It appears that I have two versions of the blockchain downloaded, and both are updating. I know Armory uses bitcoind, but is it normal to have a full blockchain in /roaming/Bitcoin and roaming/Armory?
4  Bitcoin / Hardware / [Review] SP20 Jackson in pictures on: December 22, 2014, 03:40:02 AM
Well, I got my SP20 a little later than most and didn't get to the review as soon as I'd like, so this will be a bit different than most.
Most others have gone over the basic unboxing and review of the web interface, so I won't touch on that here. Instead, I'll go over a couple parts of the hashing board for people who might not know what all the parts are.

Disassembly

Holding each heatsink on is a glob of extremely tough glue. They really don't want these things coming off. If you do get it off, you can remove the heatsink.

Under the heatsink is a copper shim, with some thermal grease at the interface. The shim had some strange imperfections though.

As you can see, there's a couple marks on the shim, right where it touches the die. Not really ideal, but it didn't seem to really make a big difference. Underneigth, well..

That's a LOT of thermal paste. Thankfully they use an extremely high flow compound, so it all just squeezes out the sides. Clean it off, and you get a much better look at the die.

That's much better. As you can see, this die was packaged in week 44, so end-Oct or the start of November. They don't have a huge lag between getting chips in and sending out products. You can also see SP is using an 8 layer board from the layer marker at the top of the image.

VRM Show and Tell
Now that we've got the board nicely take apart, let's see what is going on for each ASIC. First the top of the board.

There's a few supporting blocks in frame here. First, in green there is a DC/DC convertor that provides one of the minor voltage rails.
The blue squares are a pair of LM75 temperature sensors. These have a digital I2C interface, and they run to an I2C switch between the sensors and the minor voltage rail.
Up top in pink you have some caps on the 12V rail right near the output devices.
The center is dominated by the VRM controllers. SPTech went with two TPS40425 analog converters, in a master/slave relationship to provide 4 phases to the ASIC.
These are driverless convertors, they just provide the brains and don't drive any mosfets directly. To see the main outputs, we need to look at the other side.

Starting at the bottom, in red you can see an input inductor that filters the incoming 12V from the PSU. In pink you can see more caps on that filtered 12V rail. While the 12V rail doesn't have nearly current flow as the 0.7V output, the change in voltage wrt time (dv/dt) is extremely quick, so it's good to see lots of decoupling there.
Next in yellow you can see the main output devices, TI's CSD95372. These 60A devices are quite new parts, with some very nice looking specs. They provide the main switching that converts the 12V rail into pulses of 12V that will be filtered later.
Before the output inductors, there's two more components in blue that for a zobel network. The zobel helps to reduce some high frequency ringing on the switching waveform. It's a bit of a safety, you don't want too much ringing, but the zobel does dissipate energy so it can reduce efficiency a bit.
Next up is the main inductors. These guys are the main filtering elements, and are what change the pulsed 12V waveform that comes out of the mosfets into a very wavey 0.7V. To get the output nice and smooth we still need more filtering though.
At the top of the image in light blue you have the main output capacitors. There guys get charged up while the inductors are flowing current, and discharge it to the ASIC while the inductors are off. They also provide another often overlooked but very important protection. Because current through an inductor doesn't change instantly, if the load switches off suddenly (like the ASIC is no longer hashing) the high current will keep flowing and the voltage can spike. Often the minimum capacitance you need isn't set by what you need to keep ripple low, it's chosen to keep the maximum voltage low enough to prevent damage in the case that the ASIC suddenly stops hashing.
Lastly at the top of the image you can see the bottom side of the ASIC, with a bunch more small value decoupling caps as close to the chip as possible.


Anyway, I hope this has been a bit informative. I'm trying to fight off a killer head cold and probably have minutes left before the NyQuil finishes kicking in, so I'll check back in tomorrow to see if there's any questions.

If anyone's looking to get rid of one of these fire hazards and doesn't want to deal with AM, I'm looking to buy an AM Prisma preferably through PP. Must be working and have some kind of controller.
$450 shipped to Canada.
6  Bitcoin / Hardware / Who is Bitcoinrigs.org? on: October 17, 2014, 03:05:24 AM
Does anyone know who runs Bitcoinrigs.org? A brief search here shows that they resell AM and Bitmain gear but are also listed as a possible scam.
I got a shipment notification email from them (through stamps.com) that something was coming my way. I didn't open it, but eventually sandboxed it in a VM and looked at it, which surprisingly had my shipping address and the USPS tracking number is valid and shows something moving in their system.

I've never heard of these guys before, so I'm a little curious as to
a. Who are these people?
b. Where did they get my address?
c. What the hell are they sending me?

Obviously, I'm going to be screening people.
8  Economy / Computer hardware / 4 650GH/s+ Habanero boards, $350/each on: August 30, 2014, 04:25:42 PM
I have a bunch of samples of the new design spin coming in next week, and I need to make some room in my rack and breaker box for them.



These are just the bare boards, and buyer pays shipping. I'll do $1300 if someone wants all 4 of them.
9  Economy / Computer hardware / [WTB] XFX R9 290 (reference) on: July 10, 2014, 04:27:55 PM
I have one of these in my main computer, and wouldn't mind going crossfire if someone is liquidating their farm.
http://www.newegg.ca/Product/Product.aspx?Item=N82E16814150683

Not in any particular hurry so I'm willing to hold out for an XFX one to match, for around $200 since I see people selling them here for $220 or so.
10  Economy / Computer hardware / [WTS] Antminer S1 + Server PSU 0.5BTC on: June 06, 2014, 07:20:23 PM
I have a dozen of these, each has been running rock solid at 200GH/s since early this year. Each unit comes with an individual 450W server CPU. Dead simple, just plug in the power cable and network cable and start mining. I need to wipe my pool info anyway, so if you want let me know your subnet and I'll switch it over when I do that.

They're located in Canada, so shipping is saved by keeping them in the country though I will ship internationally. They'll ship in the original foam lined cardboard boxes.
Shipping is included in Canada, it'll be another BTC0.1 to the US.
11  Bitcoin / Hardware / The Habanero - 650GH/s - OOS on: March 17, 2014, 09:56:11 PM
Update Sept 5: All out of stock.

Update August 14: We have a very limited quantity of boards in stock and available for shipment. This is going to be the last of the rev1 Habanero stock. The price is $600.

Update June 2 / 2014:
Sales are now open for Batch 2, which is already coming off the test line and will begin shipping at the start of next week (June 9th). The price is now dropped to $850, check it out on our website.
$850 - Batch 2 Habanero


650+ GH/s
650 GH/s nominal hashing speed, demonstrated with closed loop cooler to run over 700GH/s. Proper liquid cooling is required to reach these speeds and individual results may vary.
Power Usage
About 1 Watt per GH/s, or one Joule per GH typical at nominal speeds. Power consumption can vary with underclocking or overclocking from nominal speeds as well as with different power supply and cooling solutions.
Golden Nonce Chip
High performance 28nm ASIC mining chip. Die has built in thermal controls that allow the chip to pushed to the edge without damaging cores. Designed to be under-clocked for greater efficiency, and overclocked for greater performance
Four independent 6-phase Digital Voltage Regulators
Designed using a state-of-the-art Texas Instruments Digital voltage controller and best-in-class 60A-rated International Rectifier DrMOS outputs, the supply for each die has been designed and tested to output up to 300A. With very high efficiency in the normal operating range of 150-200A, they have plenty of over head for extreme overclocking
12 Temperature Sensors
Each of the four dies features a temperature sensor on the controller chip, one at the output mosfets, and one of the ASIC die.
Custom Backplate/Heatsink
Getting good pressure on the water cooling heat is critical to cooling performance at 500W+. The addition of a custom VRM heatsink and ASIC backplate assembly helps to cool the critical power supplies while keeping the board from flexing with extreme pressure.
Extreme PCB
Designed to support the heaviest power loads, the PCB under the ASIC has 10 heavy copper layers dedicated to running power to it.
Wide Cooling Compatibility
Using a standard 75mm Intel (lga 1366 socket b) hole spacing, a huge range of off the shelf and custom coolers are available. Flexing with extreme pressure, to ensure maximal area contract between the cooler head and the four dies. Here are some cooler suggestions, Corsair H100i/H110/H80i, Coolermaster Nepton 280L, Coolermaster Glacier 240L, Thermaltake Water 3.0 Extreme. Also note cooling these boards properly important to achieve maximum throughput, so some coolers that you buy the fans on the radiators are not strong enough, we have tested a San Ace 120 12v server style fan that mounts on some of these.  (Not Included)
Power Supply
We recommend a high quality 1000W+ single rail ATX power supply for one Habanero.
Each PCIe connector is independent, so multiple smaller PSUs can be used to power one board.
If using multiple supplies or multi-rail power supplies, please ensure each connector is provided with at least 20A for maximum performance. (Not Included)
Easy USB interface
Connection is as simple as plugging in a mini-B USB cable to the host of your choice, fire up the free and open source mining software, and start mining. See (Not Included)


Original Post
Well, it's that time of year again. After too many consecutive weeks of getting a full night of sleep, a hardware engineer's thoughts naturally turn to ways he could once again start pulling all-nighters with a new design. The Chili was a great project, but the BFL 65nm chips aren't available anymore and technology has moved past them. It is time to turn up the heat and introduce a new miner project.



The Habanero
The Habanero is in the development stage right now, and should be coming online soon. Utilizing the Hashfast GN ASIC, the Habanero is designed from the ground up to push the chip as far as possible. It is going to be a pretty big departure from the Chilis in terms of scale. Whereas the Chilis had a 4-phase power supply for the chips rated at 40A per phase, the Habanero will use a 6-phase power supply rated at 60A per phase. That's over twice the max current output as the Chilis, but that's per die. Each die has its own 6-phase PSU, and is individually controllable. Whatever the ultimate limits of this chip are, we plan to find them.

The chip interface will be controlled through USB and will be compatible with the existing HF communications protocol. The plan is to expand on the HF protocol and fill in the non-functional commands like output current measurement, while still maintaining compatibility with mainline cgminer/bfgminer releases. Chaining will be supported and will be compatible with existing units, so if you have a Babyjet sitting around lonely with no MPP in sight, you can connect a Habanero right up to it (or vise versa).

Cooling will be up to the user, but we will likely recommend a good closed loop water cooling solution. More details on power consumption and test results will be forthcoming as we get hardware in hand.

Sales
It will be a somewhat marked departure from how we handled the Chilis; while we will still offer assembly services to anyone who has arranged their own supply of HF chips, we will also offer finished boards with everything ready to slap on a cooler and hook up a PSU.

Pricing has yet to be determined, but it will be very competitive.
Like with the Chili, we are not taking payment at this point. Sales won't open until the prototypes are built and tested, and the final design is signed off on and ready to go.

The Vision
When we started the Chili project, chip vendors were limited to Avalon and BFL; both companies with dismal records for delivery and customer service for their miners. We set out to do things differently and build hardware for people while still communicating with them after we had their money and delivering on time. While there are always problems that come up during a project, we gave a date we expected to start board assembly, kept people up to date on any issues, and shipped all of the first batch less than two weeks of the start of assembly.

We seem to have a similar situation today, were HF seems to have an incredible fast chip but that has almost completely shut down from interfacing with customers. Hopefully they can turn it around but in the meantime we plan to take advantage and step into that void. Our goal is to provide access to some amazing mining technology, but still be approachable enough that you can ask questions and get answers to them.

The Team
Me - I am doing the hardware design, bringup and testing, as well as my general role from the Chili project of being the community point person.

Chip Geek - Currently on vacation, when he arrives back rested and relaxed he'll be immediately thrown into the role of software development.

Gateway - Website design and help with technical support.


This thread is primarily intended to keep people up to date on development progress, I'll probably make a new one once sales start up. I don't intend to moderate anything unless things get really out of hand, but just try to remember that we are not HF and this really isn't the venue to discuss how HF is screwing over their early customers.

19  Bitcoin / Hardware / The Chili Ė 30+GH/s BFL based Bitcoin Miner Assembly on: September 28, 2013, 09:50:52 PM
The time is finally here. Iíve been dying to announce formal sales for a long time, but we were adamant that we would not start taking peopleís money until the assembly and supply chain is in place and we have the production board brought up, tested and hashing.
That time is now. The Chili is here and itís ready to go.


The culmination of a long, costly development cycle, weíre finally ready to start taking orders for assembly of your BFL 65nm SC chips. I think itís the most advanced, versatile BFL miner available. Almost every possible feature has been added to the hardware in order to really push the BFL chips.

Hardware
  • 4-phase Digital Voltage Regulator
    Designed using state-of-the-art Texas Instruments integrated driver MOSFETs (DrMOS), it provides ample power to the BFL chips. Designed for high efficiency at 100A, it can provide 160A continuous with adequate extra cooling. Voltage levels are software programmable, and it supports reading a whole range of data, including input and output voltage, per phase and total current, duty cycles and temperatures
  • 11 Temperature Sensors
    One at the MOSFETs, onboard the voltage regulator, a general board temp, and the on-die temperatures of each ASIC
  • Per-Chip Frequency Measurements
    The hashing frequency of the BFL chips is very voltage sensitive, but even at the same voltage there is a wide variation in frequency at the same setpoint between different chips. The Chili is the only board that measures the actual frequency of each chip using the on-chip clock output.
  • High Performance ARM microcontroller
    A high performance Cortex M3 microcontroller was chosen, and direct DMA access allows it to simultaneously communicate with ASICs on two SPI busses while also performing other job queuing and monitoring applications.
  • Versatile Form Factor
    Designed to be compatible with a common PCI expansion chassis, mounting large numbers of the Chili is as simple as mounting a GPU. Alternate configurations are also available; holes with the same spacing as those on the bottom of common 3.5" HDDs allow the Chili to be screwed on a HDD caddy and mounted in a hard drive bay.
Software
  • Entirely Custom Code
    Starting from a blank slate and using the BFL code only as a reference, we worked from the ground up to make the Chili as efficient as possible.
  • USB Firmware Updates
    As new features are added, the software can be field updated over USB without the need to buy a JTAG programmer.
  • P2Pool Efficient
    Because we are able to accurately measure frequency and the real hashing power of each chip, we can efficiently divide work between chips without gaps. This allows support for one job per board vs one job per chip. In addition, when a new block is detected the old work is aborted and the new work is immediately loaded.
  • Z-Link Chaining Connections
    Similar to BFL's X-Link interface, this still in development interface allows boards to be chained together and a single USB connection to be used, keeping wiring clutter in check for large data center applications - Coming Soon
  • Fully Dynamic and Automatic Frequency, Voltage and Fan Speed Control
    Fully dynamic and automatic voltage (V), frequency (F) and fan speed (S) control to maximize hashing performance while staying within safe operating parameters of temperature and voltage.  As the environment (room temperature) changes, V, F, and S will be adjust appropriately to maintain the highest hashing power based on the specified limits. This allows each individual chip to be pushed to it's safe limit without one slow chip throttling the entire assembly or a single hot chip destroying itself due to localized overheating. The user will be able to select slower fan speeds for noise sensitive environments such as bedrooms at the cost of some hashing power performance loss.
Software work is still continuing at breakneck pace to make sure that every feature is ready to by the time production is done, including some exciting as of yet unannounced features that will really allow us to push the chips to their maximum.

How Hot Do You Want Your Chili?
We designed the Chili to use the extremely cheap, extremely high performance off the shelf components that are already available in the computing industry. Got some room and want a quiet system? Grab a nice tower cooler. Looking for something high density? Use a GPU cooler and mount the boards in a 4U PCI expansion chassis. Want to really push it? Custom water isnít needed, just get a water block off the shelf. Intelís 75mm LGA115x and ATI 53.2mm hole spacing are included. Lists of recommended and tested heatsinks and thermal interface materials will be provided to ensure setup is as easy as possible, and as we develop the ecosystem custom kits will likely be offered

Pricing for the first order is $300 for parts (minus your BFL ASICs) and assembly. Contact us for shipping options depending on where you are and your preference for speed vs cost.
First batch assembly is scheduled to start October 7th, though it could start on the Oct 3rd if the majority of chips are received by then. Assembly will take place in Austin, Texas and the boards will ship from the US. Payment will be by Bitcoin or wire, contact myself at mrtealasic@gmail.com for details.
Edit: Batch 1 now closed and in production.

Edit: Batch 2 sales are now open. If you have chips that you are getting from BFL or have chips in hand, we can arrange to have them mounted on boards for you. Due to much less demands and a smaller order size, many of the economies of scale we had in the first batch will be gone. To compensate for this, the price for batch 2 will be $350.

Edit: Batch 2 is closed and shipped. Thank you all very much for your support.

Edit: Batch 3 is now open for assembly services with your chips. We are planning on starting production on the 6th of December.

Terms of Sale
  • Performance numbers are not guaranteed. While we are confident in our platform, the single most important factor is the BFL asics and we have no control of their quality. Chips are sold in mixed lots and are not marked, so it is the luck of the draw. Please don't contact me asking to get a AAA unit as a special favor.
  • There is no warranty on these items. Each units will be tested prior to shipment and will not ship unless it is working. Should an issue arise due to a non-ASIC problem we can work with you to get it repaired. BFL's ASICs are a bit of an unknown however, and we can not guarantee their longevity or reliability.
  • The price will include parts, assembly, test. Your quoted shipping price will include antistatic packaging and shipping. We cannot calculate VAT/Tax/Duty for international customers.
20  Bitcoin / Group buys / BFL ASIC Group Buy #2 - Closes July 24th on: July 21, 2013, 06:28:22 AM
I have a small window of time now, and I've had a bunch of people message wondering about getting in on a group buy, so I've decided to do it again. The first BFL group buy was a big success with 1200, but it's been awhile since it happened and I want to let all the people who've shown interest get in on another buy. After running the last one and seeing how much time is involved, I'd made a couple changes. The biggest is solely pricing the sale in BTC rather than in USD, but most other items are the same.

    Limited availability:  Chip availability is limited to 100,000 units.


Group Buy Terms
  • Payment will be in Bitcoin
  • The chips are expected to be of the mix stated by BFL. It appears that the chips will not be binned prior to shipping by BFL, so it will be a lottery. Some chips in the batch will be tested at verify the batch is function prior to shipping them out, but QA for each chip to determine its grade is up to you.
  • Lead time is still listed at 100 days. I have spoken with BFL (on June 13th) and they clarified that they have already placed orders in excess of their current needs and the bulk sales come from that, so while it's likely that the lead time from today is less than 100 days, I don't guarantee that
  • 50% of the chip cost will be due prior to the placement of the order. When the chips are ready and the final 50% is due to BFL, the remaining 50% will be due.
  • I am not responsible for taxes/duties on your end.

Cost, Coupon Codes and Escrow
    • Price for each chip will be 0.65BTC, inclusive of tracked shipping. I reserve the right to change this based on the price of BTC. This will be fairly basic; if you want something extremely fast the extra cost will be on you but we can work that out.
    • If you have chip credit codes, those can be applied and will credited at a value of 0.03BTC/code, up to the number of chips you order. IE, if you want 64 chips and have 64 credits it will be (0.65BTC-0.03BTC)*64=39.62BTC. If you want 128 chips and you have 64 credits it will be 0.65BTC*64 + (0.65BTC-0.03BTC)*64 = 81.28BTC.
    • Escrow: I do not offer escrow on chip sales at this time. The extra time and cost just doesn't justify the limited protection offered.

    BFL has now provided the source code for the microcontroller, and a design document for the chip. Reference schematics have also been posted.

    Timeline
    I will begin accepting orders and securing the funds now.  I plan to place the order on Wednesday July 24th at 5pm, so all transactions will need to be done before then. When BFL indicates that the chips are almost ready I will message everyone to confirm what they want done with the chips and the shipping address. 
    Once this group buy is done, I may do another.

    Shipping Options
    At this time, you have 3 main options for shipping.
    • Shipment direct to you
    • Shipment to someone else to get assembled for you
    • You decide to go with our design and have the chips mounted onto PCBs, which then get shipped to you.
    Obviously there's be extra charges associated with the third option.

    What can you do with them?
    Mount them into boards and start mining! There are a number of projects that are currently underway to house BFL chips. I am (of course) partial to mine, but I will list any other ones here as long as they appear serious and not a scam.
