Avalon 55nm ASIC open source design contest

[aTg]

@ ProfMac : OK....here my advice anyway :

- make it modular

Look at bitfury H-board and Rig, it's the perfect way.

+1

I manufactured and assembled 15 Avalons, wired, control units and heatsinks and is the worst design I've ever found, much worse than the old FPGAs.

The chip is specified as 1 GH/s @ 2.05 W with 128 Hash units on the chip.

This chip is DOA. There are already better chips available today. Why wait months for an inferior chip from a supplier with a horrible track record?

Yes,make it complicated please...........backplane=more money,a RSPi=more money,an unusual power supply config= ........Oh you'll need a pretty case too=more money,& a PITA interface=just a PITA

"55nm open source design contest is set to close on Nov 30th"

Is there just a winner?

Hi, what's the future plan for avalon now?
BITMAIN has sold over 100 Units probably using Avalon2 chips and they run quite well. (https://bitcointalk.org/index.php?topic=355755.0)

@ProfMac
I'd appreciate mining cards to replace the 130nm cards in my Avalons. This would be just perfect for all Avalon users, because they could use their old devices and parts like PSU, TPlink and case with the new cards. Do you think this is possible?
As far as I undestand it, a similar working card like the ones in the first gen avalons could do around 4 times more than the old ones with the same energy consumption. An Avalon Mini would have 240 GHash/s and an Avalon with 4 cards even 480 GHash/s. This is almost the power of a KNC Jupiter with around 2 W/GHash
Please correct my if i'm wrong!

The mining plan for an Avalon Mini could look like this:

Hashrate GHash/s	Increase interval days	Increase factor (25%)	Today
480,00000000	12,00	1,25000000
BTC/day	Days in this diff	difficulty	Date of diff change	BTC cumulative with diff increase

they are not using avalon chips - do your research

[AndiDC]

Yep, already seen...
but it'd be nice to replace the avalon 130nm boards...
