let me show you how a 15KM distance is a big problem...

i drive my CIVIC to the delivery station. actually 20KM away.

this is the maxim speed...

i leave home at 2PM and back at 6PM...

5 packages delivered successfully.

Beijing's traffic is a disaster. really, really. Cry

Hey ngzhang,

you should consider applying the same techniques that your product uses.

Instead of posting the boards yourself, you could UNROLL and hire 2x 64 delivery boys!

You would send them to the post office, each with another packet, and CLOCK their departures at a 1 minute pace.  At 19kph, each of them would need slightly more than 2 hours for the FULL round-trip.  Yet, after filling the PIPELINE, one packet per minute would be dropped off at the post office.  Also, every minute one IDLE delivery boy would show up again at your place.  That's just in time to smoke a cigarette and pick up the next leaving packet!!

Sustaining that schedule, you would effectively dedicate just 1 minute to delivery issues rather than several hours!  That looks like more than 100 times better!

PS:  Also don't disregard the potential optimizations.  For example you could instruct the boys to throw the packets through the post office door from the streetside, instead of entering.  That would save them a minute for sure.  You could then hire just 2x 63 boys instead of 2x 64, yet maintain the same 1 minute pace.  That would be more efficient.  Watch out for other opportunities as well!



this is my first time to do international shipment, next time i will just send the package to the postoffice by a local express (1$ pre kilo).

Any plans for a 540 or 720 Mhash/s version with 3 FPGAs or 4 FPGAs etc. ?

there is a 1.5Gh/s version in plan.  Grin
is it a scam? Angry

现实的问题是买得到还是买不到的问题,而不是折扣多少的问题。 Grin

I didn't find any documentation in https://github.com/ngzhang/Icarus, just very brief README files.
Is that the location that you were referring to?

Can you point me more precisely to where I can find the answers to my previous questions?
Thank you.

sorry, technical detailes please re-check the

https://github.com/ngzhang/Icarus

site, all project source files are already released there, so i won't explain them everywhere.

You mention that each of your boards generates about 360MH/s.
Is that one mining instance running at 180MHz in each device, or two instances running at 90 MHz in each device, or some other configuration?

How full are each device? How many slices are used in each device? How many flip-flops?

Icarus project is a GPL'd open-sourced project, please check github for these questions.  Wink

I am very interested in these as well. Anxious to hear the reviews!

I'm also anxious to here the reviews. so i decided to start the second batch after some reviews posted on this thread.  Grin

Okey Dokey Lokey
When someone gets these let us all know how it goes.
I wanna get some FPGA miners, and i've been looking at Butterfly labs, because the product is so clean,
But this guy has Clearly working FPGA's
Where as Butterfly labs has yet to show working FPGA's

ah, first user appeared. i just give 1 board to xiangfu @ beijing by personal.

That's nice, but I would like to play also with Christmas, why don't you ship the orders that are paid for ?

 Grin

oh, i must go to a post-office 15KM away to mail internationally, my plan is after all buyer's payment is finished, than ship them all together.

this morning, last one payment is finished, and i pack all icarus to box tonight, tomorrow they will be all send out.
