When will the second batch be ready? Thanks

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

2nd batch has 30 boards,  i will get them next week.  Cheesy

I have to do my groceries at a distance of 15 km so I don't understand why this can be a problem ? Oh... no... you don't have a car?


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

Ouch! Shocked I didn't know that. But it's highly appreciated, thank you very much ! Smiley

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?

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.

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

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).

Did the government take the boards or why does no one post a review ? Seems to be a very promising product !

I received the Icarus package today from ngzhang Smiley

Shipping to Europe took 9 days.
It was well packed and complete as promissed.

The package contained also a USB stick with all software needed for mining, experimenting and dev.
Within 10 minutes my Icarus dual fpga board was online and mining at Coinotron.
During mining the device uses 26 watt 21 watt and the short breaks in between blocks 5 watt.
The hashrate at Coinotron moves between 200 and 400 Mhs/s, but now the pool is down so I think it's a pool problem.



btcguild:



deepbit:



My first thoughts after mining for one hour are that ngzhang made a great fpga board with a lot of potential.

One point of criticism, the tiny cooling fans make noise.
(Only the first hours of operation the fans made noise) I think it's now 10-15 db, a normal pc makes more noise.

Thanks Zhang for your hard work and I will be the first to buy the 1.5 Ghash fpga from you, with 10% discount Wink

Good news. Looks like a high quality product. What size are the fans ? 40mm ?

good, first.

network conditions is deadly important for the real world mining speed.  by my test, a 300-500ms ping speed to deepbit.net will generate a 330MH/s real-world hashing power.

 Huh

there must be somthing wrong with the power consume. Icarus never uses more than 21 watt, less than 20 is a typical. and the idle state consuming 2-4w typ.
i uses a 1% grade meter for the test, my be one of the meter is not dependable?  Huh

and, please, please keep this thread to Icarus. the 1.5G rig is really really at a plan now, the SPEC./ speed/ price .... and so on is not tested in real world and not decided yet, i will not announce it officially until i have at lest 5 of them for mining 1 month +, i don't want to be called as scamers. Cheesy the development just started and looks like at least will take half year or even longer time to finish, it's a very hard and complex design, really. so please don't ask any time table or something details like that.






Good news. Looks like a high quality product. What size are the fans ? 40mm ?

it's a 25mm fan...

Nice! Can't wait for that Smiley But I'm also wondering if you have a timeline set for an even more powerful board?
