Hi

I purchased a used SP20 and did not receive it with user name or password so I can't get into it. I would like to restore it to defaults but the Spondoolies support web page is gone now can anyone tell me how to do the factory default?

Thanks
Randy 

I have 2 miners as well and they have both stopped working about the same time as yours. What did you do to fix them?

Thanks for your help
Randy

Thanks VS3, this is a simple interface but my real question is what will it take to get CG, BFG or any other miner talking to the ASICs? In this configuration there can only be 1 "H" card (16 chips) so the processing power is not really a factor but since I DO NOT do the software thing I need one of you programming gods to chime in so I can get an alpha PCB on order. If I am wasting my time just let me know.

Thanks
Randy

Hi and thanks for your excellent feedback, the chip can be and is configured to operate using 1V8 so no level shifter should be required (one of the reasons I selected it) also it is very configurable with the utility. Just a few of the specs are;

Single-channel configurable SPI interface ❐ Master/slave up to 3 MHz ❐ Data width: 4 bits to 16 bits ❐ 256 bytes for each transmit and receive buffer ❐ Supports Motorola, TI, and National SPI modes
Configuration utility (Windows) to configure the following: ❐ Vendor ID (VID), Product ID (PID), and Product and Manufacturer descriptors ❐ UART/I2C/SPI ❐ CapSense ❐ Charger detection ❐ GPIO

The link for the full spec sheet is here; http://www.krw.net/cy7c65211.pdf

Also please keep in mind that this is simply an interface to allow a computer to provide the processing power not the UART.

Thanks again

Hi
I am interested in developing the Bitfury “H” board into a standalone (computer driven) miner, I am primarily a hardware engineer and do very little with software so I need some real help. I would like to propose a single chip interface (CY7C65211) as the USB to SPI adapter. This UART is very flexible and from everything I have read in the forums just may work. I am fully aware power brick will be required and I have omitted the “H” board power connections from the drawing. I really am interested in your comments as to if this is even possible and if so what software would recognize it. I am inserting a rough drawing for your review and comment. This drawing is basically direct from the app note.

Thanks and please be kind.     

Hi

I am also fairly new and of course very interested in Bitcoin. I do enjoy making money (who doesn't) but I also like the technical side of how it works. I am an engineer by profession and I am looking forward to getting more involved in the mining hardware aspect of Bitcoin.

Best wishes
Randy

Hi

I have also ordered the Kit with extra cards, I am also considering building a card rack because I do not like the idea of have the H cards flopping around.

Thanks
Randy

Hi

I am interested in developing a Bitfury H card USB interface, this would allow a single card to act as a stand alone miner. Has anyone tried or developed this?

Thanks
Randy
