Hey dadj,
Interested.
So you haven't ordered any chips yet? Avalon's web site says they are sold out. Or you have and are expecting 10K chips to arrive "Late Aug / early Sept."?
Hi QG - yes, we haven't ordered the chips yet.
100GH/s is based on air cooling? I thought a 4 module Avalon ran at 90GH/s? How do you account for the extra 10GH/s? Do you own a 4 module and have achieve these rates? What's the power consumption?
Yes, air cooling. I own a 3 module and achieve around 65 GH/s running normal speed. Overclocked it gets to 70 GH/s but I only overclock to 300M. We arrive at 102.4 GH/s from 320 chips x 320M frequency. Power consumption would be in the 660w range from a standard PSU.
I'd like to know more about your teams experience. e.g. Who's your head Electrical Engineer? What practical experience does he have? I presume you have someone with programming experience too?
ub3rCoin is our EE. He has practical experience in circuit board design and modification and will post some pictures of circuits that he works on soon. He is also proficient with C.
Will the progression of this project be base on number of investors? i.e. it will not go ahead unless you get a min. amount? or it will go ahead and production size will vary?
Yes, production is dependant on investor interest. Chips will only be ordered if sufficient interest is here (and if they're still in stock!)

How many $/kwhr do you pay?
Dependent on various factors: pps or pool option / variance & future difficulty
Do you have a manufacturer?
We will be doing the manufacturing in-house. We have access to surface mount technology equipment and source our parts from Avnet, one of the most trusted electrical components suppliers.
So if I pay you to hash for me I am paying you about (+/-) $80-$90 USD per GH for device that will be delivered in September?
and if I buy the Rig I am paying about the same rate per GH $70-80 a GH?
BFL is $50 a GH probably for the same delivery time
and
KNC is $17 a GH for Sept/Oct delivery time.
I understand your cost just on Chips is about $2500 USD per unit
Just saying the days of 100% to 200% profit margins on hardware are getting hard to sell.
Best of luck on your project!
Thanks, we realise that the chip delays are the big hurdle from Avalon & BFL. We are not locking in with Avalon at this stage and are looking at BitFury chips as a better alternative. We have requested sample chips and will keep this thread updated on any news.
