Old posting:
I got some next-gen Avalon 55nm chips and arranged them on a board to test their communication and explore its options.
The BkkCoins' Klondike implementation was a big inspiration for me, so the design and the firmware is very similar to it - So no need to reinvent the wheel again.
Wherever BkkCoins is now, i wish him all the best, and may he come back soon.
I'm still searching for people who want to contribute to this project.
If you have some ideas for features of the board, please suggest them on
https://github.com/formtapez/avalon or at #avalon2 on FreeNode IRC.
