Hi, I am slightly modify the specifications of this project. Max. hashing power will be 9Gh/s. It will contain three avalon modules - each 10 chips per board. Avalon module will be powered from onboard 108 W DC/DC converter. http://i43.tinypic.com/izryav.pngHi, any plans to extend to >100 Gh/s in the future? With a dedicated power distribution board driving more then a 30 Avalon chips, for example!? The Cortex M3 CPU should be able to handle more, am I right? Thanks one4many

1 of my samples from batch 1 (early july est) is now promised to this project.
Ill get it to op quick as I can.
Nice move dude - :hi5:

UPDATE:Great news. PCB for avalon module is partly finished. (there are still needs some cosmetic changes ) http://i44.tinypic.com/qzkumf.png

I have high hopes that your time to market will enable many to deploy these ASICs at the given hash rate while it can still earn, given the rate of rise of difficulty we are now seeing.

Are you releasing the diagrams at some point or just gonna be selling the boards ?
I have a rather friendly assembly plant here in the uk now, or are you aiming for these to be hand toasted and/or home etched ?

Hi, sources will be released as soon as possible firstly for sponsors At the beginning hand tousted PCB but I am asking for assembly plant.

Hi, I am from Slovakia. Today I make video whitch is presenting communication between PC and miner. Board generate random nonce for testing interface only because I am still waiting for avalon asic. Between two jobs is 10 miliSec delay and board send debugging data to another usb so only cca 7Gh/s rate is reached. http://www.youtube.com/watch?v=wq5wDlMY8u4

Hi, explorer232, greetings from Czech Republic!!! As we talked here before, I'm definitely interested. I made a little simple investigation about return of invested capital and avalon looks good for now. (Real parameters will be different, but for imagine and comparison it's enough.) I have to say I don't know details of your design, but there is possibility of overclocking, as described in datasheet of avalon chip. (And discussed in other avalon-clone threads like this). Did you think about possibility of supply voltage/clk frequency tweaking? And second note, please think about 28(-35)GHs variant, I mean 10 avalon modules shield. You always can use 3 modules only, but benefits of modularity are known ;-) If I can provide you any help, feel free to ask. Ramirez

Your project should been encouraged! Do you need Arduino DUE boards? I do not know the price of Arduino DUE board? I am from China. If I can do something, pm me. Thanks

Ramirez Hi , in my design is definitely posssible change voltage for cores by replacing one resistor on the power board. I dont know the internal structure of Avalon, so I dont know whether external clock is used only for cores or also for internal logic. Tweaked oscillator frequency could cause data corruption.

Hi, unfortunately at the moment this project is financing only by me. Evilscoop promised me 1 avalon, so I'm waiting for it. This week I will have electronics parts and pcb for the first prototipe.

Very impressive. I created a similar project with small differences (well some people might see them as large). I created modular boards that could support various chips at variable power levels... it was mostly a way for me to learn the inner workings of Avalon, BFL and Bitfury ASIC's chips without actually having the chips in my possession (I do have a prototype board already professionally etched/printed and awaiting Bitfury chips; no idea how I will get my hands of them when they are released ). I started off years ago with Microchip's MCUs and was able to visit my roots with high-end but low cost 32-bit MCUs running FreeRTOS (I started off with a loaned Xilinx Zynq-7000 devkit since I'm very familiar with ARM and Xilinx FPGAs, however an unknown person at work placed an old CRT monitor on top of the board and completely ruined everything, however I have other plans for the Zynq so I hope to somehow get my hands on another devkit). Keep up the great work!

query Are you building in a way to overclock ? Avalon have stated their chips can be ramped up a bit from default
