DiY ArduLonMiner

[explorer232]

Today arrived to me 1 AVALON chip from evilscoop   Thank you for it Because at the moment I dont have prototype pcb, avalon arrived very fast, make a bit hack . I designed simple test board for chip and this is the result. When arrive to me electronics components I can to test the miner. This project consumes all my free time and quite a lot funds so if you think I have been helpful donations are welcome.

Great news !!!

nice work, watching this project now...

Wonder if you could use a few more feed thru under the Avalon chips to help with heat transfer.

[evilscoop]

nice breakout board...lets hope you can get it talking to the arduino soon

much better, 5x5 holes

Did you realease your own library to communicate with CGminer. How do you receive de work unit and how do you send it the to Avalon chip?


Im going to try to do the same with a Leornado card.

I thought you might be interested to know that Bitfury are doing a sample chip program for developers

Getting samples for fury is a bit harder, lots of interest..
But a shield for those would be worth many btc

A 10 chip BF shield would be 50 GH/s. The avalon shield would be 3.5GH/s.  I have a feeling I know which one would be most popular.

Indeed, and If I get some samples of these, some will find their way to this project

Nice work!
Greetings to Slovakia from Ukraine!

I have two questions:
- Will this shield be backward compatible with Arduino Uno?
- And what is needed to adopt the shield/rig board to bitfury's chip?

Thanks!

Very very very unlikely: the DUE has an ARM-A3 and communicates at 3.3v compared to the 328's 5v!

ARM-A3:
A 32-bit core, that allows operations on 4 bytes wide data within a single CPU clock. (for more information look int type page).
CPU Clock at 84Mhz.
96 KBytes of SRAM.
512 KBytes of Flash memory for code.
a DMA controller, that can relieve the CPU from doing memory intensive tasks.

Whereas an Uno has a 16Mhz 8bit CPU with 16KB of ram.



Loving the work btw, hope you get some bitfury chips! At 0.5w/ghash they look great.

Thanks for the answer!

Bitfury is out of testing chips right now. There's a big boom about this small hulk.
I saw them in my hands, but since I am not a skilled engineer, there were no use for me to take them alone.
But since the project for Arduino is kind of niche market and I like the idea, I will do my best to have the chips, when they will be available.

P.S. You mean, UNO is too weak to serve as a tunnel from ASIC-rig to Host (PC)?

UPDATE:

Arduino read / write config from/to AVALON correctly

Great!!!! Can't wait for first accepted share ;-)

nice, i'm really liking the look of this little project.

Hi, I have problem with my miner.

1. I send config to Avalon (I checked this part many many times and it seems to be okay)  LSB (first bit, byte, word) [8B - Clock Config] , [12B - data], [4B a1],[4B a0],[4B e2],[4B e1],[4B e0], [32B midstate], [4B a2], [4B nonce - 0x00000000 - 1 Avalon chip]
I use multibit transfer ---- IDLE first bit ...... last bit IDLE  
Avalon is clocked to 256Mhz.

Precalculations: I think its ok. Precalculated values are generated from midstate & data. I could like to send precalculated values for specified btc block [data, midstate]

2. Avalon send me nonce, nonce is correctly decoded by arduino (checked by osciloscope)

3. Received nonce is shifted about 0xC0

BUT golden nonce is not valid.

Config frame:

I dont know if I have a bug somewhere or my avalon is faulty
