About using an external power supply to power our FPGA boards-- Quote from: makomk on August 28, 2011, 09:42:53 pm
Quote from: xurious on August 28, 2011, 12:44:26 am
Or for about 1/1000 the price of one of your PSU dummy plugs you could cross the green and any black wire with a paperclip.
Alternatively, you can buy the connector and a crimping tool and build your own. (Plus, that way if you're electronically inclined it should be fairly trivial to rig up remote power-cycling - an Arduino, a NPN transistor and some simple software ought to do the trick.)
Can anybody please explain what the objective of this is? I have an excellent crimping tool and reasonable electronics knowledge, but I don't get what the problem is or what this dummy plug is supposed to do.
I was confused about what that jumper does, too. It just sends the PSU a signal, telling it to turn on. Usually the motherboard does this. If you run the power supply externally, the motherboard isn't around, so you need to have a jumper to another source. (or, well, ground in this case...) http://www.overclock.net/faqs/96712-how-jump-start-power-supply-psu.html*Disclaimer: Paper clip method not recommended, due to lack of insulation and possibly not enough current capacity. Current capacity is negligible, all it has to do is overcome an internal pull-up resistor in the PSU. A little electrical tape should take care of insulation. No need to buy any kind of dummy plug just to turn on a PSU. |

In that case why not just pop the cover and bridge the pads with a bit of hookup wire. Alternatively, I think there are two wire bridging crimps you can use with normal pliers. They fold over the two wires and have little metal jaws, that cut through the insulation and make contact with the wires inside. Neat, simple and cheap. Edit: I found a Pic: |

 Egad!! I just looked at that software from Xilinx it's 4.62 Gig. Good grief, what is all that code for? It says it's a design suite. Is that really necessary to run the mining environment for the end user? I thought the idea of a FGPA was that it does in hardware what would otherwise have to implemented in software. I'm still not convinced that I couldn't get away with running whatever software is needed remotely, over a network connection. Why can't a WiFi / Ethernet link support the FPGA board with software being run remotely? Assuming we have serial interfacing on both devices, the need for a dedicated CPU/memory/board should be eliminated - well, I imagine, at least. I want to connect these units over a VPN/WAN, so although they are stand alone (physically), server support and remote process serving should not be an issue. As far as I'm concerned the software could be deployed in a virtual appliance. In fact, that would be all the better for data center management (upgrades, security etc.). The end user environment IMHO, should be as simple and abstracted from system management as possible. It should also avoid physical on site maintenance of individual units at individual locations. So I fully intend to leverage cloud based solutions and virtualize whatever is possible. Also, I forgot to inquire. Would this FGPA miner afford any advantage towards R&D of an asic based solution? Is there any/much benefit of having a good FGPA based design to leverage a future asic device? Just out of curiosity.

The X6000 and X6500 boards will not require an ISE installation at all. I am writing the software to control these latest boards, and it will be very light weight. Also, I forgot to inquire. Would this FGPA miner afford any advantage towards R&D of an asic based solution? Is there any/much benefit of having a good FGPA based design to leverage a future asic device? Just out of curiosity. It most certainly does. In fact, there are many companies that can take an FPGA design and convert it to ASIC. |

We started a new thread for details about the next generation FPGA boards (the X6000/X6500s): https://bitcointalk.org/index.php?topic=40058.0This will hopefully be the best place to look for updated information on these boards in the future (and keep it separate from the X5000 information). |

UPDATE0 Aug 19th 10:00 - I ordered Xilinx USB platform cable through ebay.de for €41.50 = $59 incl. shipping from HongKong.
UPDATE1 Aug 19th 10:10 - I received an invoice from Li via paypal and payed $440 (+$12 for shipping and handling) = $452. I noticed my shipping address in paypal was a very old address of mine and PMed Li with the correct address. I hope it'll work out.
UPDATE2 Aug 19th 10:20 - Li confirmed receiving the payment and also confirmed he would send to the correct shipping address.
UPDATE3 Aug 23rd 06:42 - PM from Li, saying he shipped the board! Gave me tracking-# and ETA 6-8 days.
UPDATE4 Aug 30th 13:30 - Received package containing FPGA miner "built with care". Also received Platform Cable same day  now what? I'm afraid! |

Pricing looks to be in the $200 range.
Where did you hear that? Sounds like their parts aren't available from retail distributors yet (nor is there any timeline for that to happen). |

You should put your company on the GLBSE and distribute shares to raise funds. I'm sure alot of investors will support you. I had no idea people were doing such things, I must visit this forum more often.

you mean this (see below) I hope my suggestion wont be taken as trolling...
how about setting up a company to garner resource for research and selling the end product to the btc community like what you guys are doing here..
except that those that actually buy into the company will either get profit/discount on the product...?
IE...
total dev cost is $5000
total manufacturing cost is $5000
(these are just assumptions.. i'm sure someone can make a better accurate depiction of how to do this...)
so you would sell 10k worth of shares for the first round to buffer for this...
the dev who put in time and money would be covered by the shares representing their hardware cost and dev time... may be 1/3 of the total shares?
the rest is open for public buy-in...
when boards are sold... the profit is divided upon the shares hold... and distributed among share holders..? if shareholders wants to buy at discount they get a % related to the % of shares they hold...?
just a suggestion... nothing more ...

Yes exactly that. Something very exciting to invest in. |

One question: is it safe to plug in/out the power plug while the PSU is on? I'd really hate to have to power off my system for this (my X5000 currently runs on it's own PSU but I want to switch to the one used by my wall-pc)
