what kind of external fans do you need on those? I can probably make a design for this PSU if I can have easy access to one and if the mating connector is easy to source. Small custom batches are 10 boards. Edit: The PSU looked familiar, and after checking my spare parts stock, I know why. I have 6 of the right angle mating connectors in hands. FCI ref: 51761-10002410A A Edit2: I did a quick estimate of price for a batch of 10, you'll be roughly at 45$ each board with 8-12 PCI-E plugs and fan headers if needed (not PWM), design almost the same as this one: http://imgur.com/a/4UWcr#7Delay ~2 weeks |

ive been waiting since 2015-02-17 for a HEX4RBox
sent 3 emails now to them and not a single reply and 3 dates have passed on there site for shipping and yet no box or even a reply to my emails
good ive pay for them via paypal
going to give them 2 more weeks and still if no box or at the very least a email will report them for fraud as there selling goods i don't even believe they have
if your reading this TECHNOBIT my order is FUCVIKLCA
i suggest you get back to me asap
I'm waiting from 2014-12-21, and I don't get my money......Looks like Martin Sirakov aka Technomachinex/Technobit from Sofia ran off with the money, that is $565,000 in bitcoin alone, plus a yet unknown amount in cash/bank/credit card payments. Has anyone contacted their banking or credit card company yet and reported fraud? I can't believe the inertnes of some on this matter while Martin Sirakov is laughing all the way to the bank. Time to address Bulgaria's justice authorities on this matter, this guy belongs in prison. Where did you get those number? I'm glad I never had too much trouble with them, Martin even sent me 2 bare hex8A1 boards so I can fix one that caught fire. But the Minion chips assembly thing smelled fishy quite fast, considering I bought an Hex4M on their shop last year and had it delivered in a few days while at the same time, the guys who had sent him their thousands of chips were (are) still waiting because of "technical issues". |

thank you... but this solution to reflash controller (pic32mx cpu).... i need pinout rx/tx connected to hash board with uart (cp202) - and working through cp2102 - without controllerboard hashboard+cp2102stick You can do that - connect a CP2102 directly to the S3 board(s) and then start a cgminer instance on the PC you've connected the CP2102 (just as has been demonstrated in this thread for the S1 board). You'll need 2 CP2102's though for an S3. You may need to hack cgminer a bit (again demonstrated in this thread) but it should work "out of the box", so to speak. Almost out of the box, it seems: https://bitcointalk.org/index.php?topic=671128.msg10537640#msg10537640I have 2 C1 dead hashing boards to experiment with. I'll have a look when I'll be home, by the end of this week. It seems that the C1 boards can be plugged on the S1 to S3 upgrade kit but the 20 pins connector is flipped, so pins won't match unless you remove and flip the plastic part of the receptacle 180°. First things I noticed is that you have at least TX, RX, GND, 1.8v and 3.3v to connect, not only TX/RX/GND. |

Back from holidays with a quick update:
New design boards with PCI-E plugs instead of screw terminals have been sold for the last 3 months, I'll take some pictures of them to update the first post.
The following boards are concerned:
DL580 G3 STD (8 PCI-E plugs)
Common Slot STD (8 PCI-E plugs)
DPS2000 BB XL (12 PCI_E plugs)
All the boards including the Bladecenter H 2880w are now in stock.
Double ended PCI-E cables are also available in 24" and 36" as well as custom length.
DL580 G3 XL is discontinued because of the lack of supply on the main connector
Common Slot XL was repleaced by a STD version with 8 PCI-E plugs (more than enough for 1200w)
A new board will also be released soon to allow those with faulty S4 PSUs to have something really close to stock size but with more power (at least 1600w) and that can be powered from 110v.
The product reached its final steps: design of the enclosure that will be attached in place of the original PSU.
Do you have the DPS2000 BB XL (12 PCI_E plugs) in stock? Cost? UPS Shipping cost of 1-6 boards to Longville, MN USA 56655 ? Thanks, PlanetCrypto.com, LLC Jeff Schlenker, CEO 1199 State Hwy 200 NE Longville, MN USA 56655 you got PM |

one board literally does not hash no matter what port or cable i use or clock speed, i tested this with the other fully disconnected. I was looking in the kernel log and its reporting power error. I tested the vdd's and they are all the same as the working board, so maybe its something else.
edit:
Its not hitting 80c, its barely breaking 55c for me. I'm just saying the guy said it got hot and shut off on him.
Your boards are gone. This is big mistake of BITMAIN, their S5 even they stop mining, the are the same power of like when mining. If your miner overheat, the chips are very good piece of silicon, they survive, but they melt soldering and desolder power pins. At least two of them are desoldered. You can use regulated power supply, set it max. to 8A and 9V, set 100MHz and start your S5. Try to press every bottom side of each ASIC, you will probably find two desoldered which pressed are temporarily working. Do not try it at full Amps or at 12V, it may brake your PCB. So basically, if you are right, adding a little bit of solder paste and reflowing should put it back to life. can you put a pic online with which power pins are desoldered on yours? I didn't search, so maybe you already did. |

I have a board with similar issue that will come back unclaimed/refused by the RMA recipient after 1 month. I'm glad they did cross shipping on this one. The board failed within 2 weeks of delivery from Bitman, temps were never over 60°C I'll have a look at it to see what can be done to revive it since Bitmain refused the board. Also, I noticed that the board was losing chips whenthe S5 was unplugged while "hot" like 60°C and not restarted immediatly. |

Yes based on the schematics the chips are designed to be two completely separate systems, each BTC and LTC core are chained independent of each other on their own serial bus with their own power. Curious to see how they handle this hardware wise....they could just slap two USB ports on them and call it a day, but that would be a nightmare for setup.
Simple USB port with dual USB-UART bridge converter will be the easiest way for hardware. I haven't had time to work on the design this week because of orders and a little bit of private life, but I'll resume next week. I updated my dropbox folder with latest files and added a txt file to track updates. |

need help, the psu arrive today, but something wrong with it everytime i plug it it short circuits and mainboard of my home electricity shuts off, what can i do to plug it???
hi, sorry, i already find out whats was wrong, one of the screws of one of the fans was touching something inside i open it and fix it, now its working perfectly, thanks As I said yesterday, the PSU was tested before shipping. That's the reason why the fans were still plugged in the breakout board when you received them. I'm getting the fans with bare wires and I add the connectors myself. Testing before shipping allows to check the following: -Functionality of the breakout board -Functionality of the PSU -Functionality of the fans and correct polarity of the connector But the brass spacers I'm using could have moved during transport to touch something inside the PSU. Your feedback will help to improve the service, so I'll add some insulation to the next DPS2000 kits to avoid any future issue. |

Did you buy a BE 2.0 controller or 1.0 controller? Prisma 2.0 units are not compatible with cgminer and not compatible with the BE 1.0 controller. It's a shame, but I think that's the way it is going to stay unless something miraculous happens with ASICMiner.
For reference, BE 2.0 controllers will display the following version information in the header
BE200 String JET Stratum Miner V 2.27 (JS)
If you need to buy a 2.0 controller, let me know. I have a few left over.
I was able to get about half speed using an USB adapter, but only the BE 2.0 got me full speed hashing. The only external difference I could find between the 1.0 and 2.0 controller was that 1.0 is supposed to be powered with +5v, and the 2.0 uses +12v At least, that's what is written on them. |

Ok, I've been working for almost 1 year now when I had time to try and imagine the next mining revolution.
First steps were made with the GC3355 chip in mind, that's why I had most of the schematics ready for the SF3301.
We had CPU, we had GPU, we had FPGA, and now ASICS, next step will be "waste heat recycling":
to replace most of the heating elements needed in house / offices by boards populated with asics.
-Tumble dryer will be one of my first trials later this year since I have 2 of them with defective heating element.
They only need 2 settings for power: 1000w/2000w, so easy to do with a 2 boards setup.
-Space heaters have been discussed for some time now, and I'm sure they will be the first commercial step to this revolution.
-Central heating can even be imagined with a large liquid cooled unit, with heat exchanger to use in a similar way we do with heat pumps, either to replace completely your furnace/boiler, or to help it.
-Low temperature drying is also a good candidate to get potential buyers.
Basically, everywhere you need heat, you could generate it with computing power (and get paid for it) instead of wasting this heat and paying air conditioning to cool down the miners.
Then, we have 2 options:
-selling the units and letting the buyer do whatever he wants with it
-selling the heating units, use the hashing power for cloud mining, and give back some money to the buyer based on the up time / mining revenue.

Hello,
are there any adapters/boards available which can power a KNC Titan (4-8x PCIe, 1600W + 1x5v Molex for Controller)?
Most boards "only" have connectors for PCIe, but I wouldn't like an extra PSU for the Controllerboard. Any suggestions?
Kind regards
I've been working on something to power a Raspberry and optionnally charge my phone from my server PSUs while I'm messing around with the miners. I can make a little upgrade to the circuit board to also output the +5v to a molex connector. I'll need up to 2 weeks to have some of those boards in hands. |

...and to be clear. Im really looking for a complete ready to go, plug and play power supply, that just swaps, but is better quality than the bitmain oem psu.
Am I correct on my diagnostic. Yellow led "alarm" light on in back of PSU means bad power supply?
Vegas
Once finished, this will be a drop in replacement for the original S4 PSU. Regarding your yellow light, here is what BitmainWarranty answered in an older post: https://bitcointalk.org/index.php?topic=796839.msg10061064#msg10061064 |

anyone making breakout boards for dell poweredge 1855 power supply? let me know, Ian
Not yet, it may be a new one when I'll have some time to work on it. |

Thanks for the advertising I'm currently working on a PSU + breakout board that will fit inside the S4 to replace the stock ones when they fry.  The last thing still missing is the cage/housing to attach the psus+ breakout board to the existing S4 frame like the original PSU. I have a few boards in stock, but no delay yet on the housings. The breakout board can use up to 2 Common Slot PSUs, so you will have quite some options to power the S4: 2x1200w 86% (DPS1200 FB A) for cheap fix and overclocking ability 2x1200w platinum if you want to overclock and stay efficient 2x750 platinum for stock settings and efficiency 1x1200w for underclocking (cheap or platinum, it's up to you) |

Small teaser for the S4 PSU breakout board: White connector is for the remote switch. And here are some pics from developpment. http://imgur.com/a/3G5zL#0The white plastic sheet was used to simulate thickness and dimensions of a metal sheet for the enclosure. |

The power boards are probably based on something like tps40140 or ltc3829.
They could have been ordered separately. worst case, they can be used to work on other chips later.
But I expected the power supply to be built in the dev board, and price for the dev board is almost twice what I expected, so sample chips will be fine and more fun.
Anyway, my 2 chips design only needs routing to be finished.
I've been away today and will be driving back home tomorrow (9hours trip at least), so I probably won't update until Wednesday.
Sample chips price is a little bit high too, I expected something closer to 50$ each, but if price for "small batches" is right, it doesn't really matters.
Before I buy 2 or 4 of them, I'll need some more technical informations than what can be found in the partial data sheet.
I'll check tomorrow or Wednesday for what's missing.
Can I assume the chips will be sent express (dhl/FedEx) within 1 or 2 days after payment will be made?
Yes, we will ship (DHL/FedEx) within 48 hours after full payment. Thanks for the confirmation, here are some of my questions regarding the chips: Can we supply non symetrical voltages to body bias? Let's say +0.8v and -1.1v This could be an option to improve a little bit the global efficiency. Also, can you confirm that both pairs are supposed to receive the same voltages? BTC_VDDS0/1 BTC_GNDS0/1 I won't mix voltages, but since there are 2 pairs of pins, it could happen on different designs What do we do with the last chip downstream UART pins? Left open, pulled up/down? Your schematics, with the 4.7k resistors, seems to suggest pulled up, but even the pins in use are shown with the same 4.7k resistor. So it's not really clear which ones do need what. What do you call "internal oscillator" Is it an oscillator built in the SF3301, or does it refer to the on board oscillator? And last one for now: Will you provide the software you used to test the dev board in your github? Sorry for my delay to response. As for your question, please kindly find the answers below. 1. for non symmetrical voltages to body bias, we don't recommend it. 2. BTC_VDDS0/1 and BTC_GDNS0/1 are all for BTC, because the BTC has 160 cores and the area is so large, we need more pad to drive them. 3. if you have only one chip, for DNRX, please pullup. DNTX don't need any action. 4. internal oscillator, the SF3301 has an internal OSCILLATOR, but it need an crystal to connect XCLKIN and ZO. so if you use it, please reference the following schematic. Please note “for internal OSC”, at the same time, please connect the 2/3 of J1, make sure the OSC_BP = 0.  BTW, we will upload the software very quickly  Thanks, you got my shipping informations, I'm now back to routing the board |

I'll do once I will order the chips. For now, I still need the informations I asked earlier to be confirmed by SFARDS. I'd like to arrange delivery of the bare PCBs at the same time I'll get the chips, but I need to have those informations confirmed before I send the files to the manufacturer. J4bberwock are you going to start a new thread for your project soon here in Hardware? The power boards are probably based on something like tps40140 or ltc3829.

What do you call "internal oscillator"
Is it an oscillator built in the SF3301, or does it refer to the on board oscillator?
Is one on the PCB not visible on the right of their board picture? yes, and it's also on the schematics, but even if you have an internal oscillator, It's quite common to use an external one for some reasons, so the "internal" word may be a translation mistake referring to the one on board as opposed to the one from another daisy chained board, the signal being transferred by the coaxial cable (RF receptacle). |
