Will you be contacting the people who pre-ordered via email? I don't always watch this thread so I was just making sure.

yes, i send about half of the email, then start the payment and ship.

tomorrow another half, and payment, and ship.

today i send out 10+ packages. Grin

today i tested a fan failure issue.
the board will get very hot and generate some wrong data (invalid rate = 10%), but still alive (in some hours).

What was the environment temperature in your test?

23 centigrade

What is the voltage range of Icarus ? 12v only or can i use higher voltages ?

designed for 10-14 V. 14.5V absolute.
but only tested under 12V.

waiting for the post- man now..... Cheesy

Hi all

I changed the branch name to 'icarus'[1] now. it support multi-icarus very well.(openwrt package[2] also updated)

I disable the auto scan under linux because we don't have a unique ID on PL2303 eeprom.

Hi All

I am working on add Icarus support to cgminer:

That's good to hear. I was worried because here, everything that has a declared value bigger than 50 dollars gets taxed to hell and back. Even if it's for non-commercial use. First a 24% VAT and then another customs tax that for electronics can go up to 30% of the resulting sum. It's quite prohibitive. And I'm not that partial to paying more than half the value in taxes.

Demo, looks like you are Portuguese...
Not only the VAT is 24% but also if they don't agree with the value the border policy atributes a value they think its fair (as they know that the hell they are handling) and you only get a notice 30 days after it arrives (at least in Portugal) asking you to send them the invoice copy and you wait another 7 days...
Even if you pay VAT for shipping to the sender... you'll pay VAT again for the total invoice plus taxes they say you have to pay for their service, the dog's food, the bird water the cousin toy, the uncle teeth... all of this if you want to get the product that you already paid for...

Yep, Europe. Used to be 19%. (No, I'm not in any of the PIIGS countries).

24% is crazy high. Let me guess you live somewhere in Europe? I hope someday we will live in a world where there will be free trade not just for big multinational corporations but for us regular people.

Hey, wanted to ask people that received Icarus boards already - what was the declared value for the package? The real value of the products or some lower, arbitrary value? What kind of customs taxes did you guys pay?

It was a lower value - as it should be. No custom fees - once again as it should be.

New cgminer release (2.3.0) supports icarus.

Now that is good news.

let's discuss about the pool selection.

in brief, if you have a large ping, please use the queue version of the miner software, but it will cause a higher stale rate. about 1-2%. but the FPGA could run at a full speed.
but if your connection is unstable, it has already been found that both miner software sometimes get stuck.

the both simple and queue miner will not continue or fix. we will change to a more common use miner, like CGminer or some other stuff who want to support icarus. there are already some people working on this.

Quote

I'm sure it hasn't yet. My question was more a what if scenario aimed at understanding the dependence between the FPGAs. If one were to be damaged/abused how would the other one be affected. If one gets sick/dead does that render the other also inoperable? I'm not saying anything is wrong but it's good to understand how they relate to each other. From looking at the code it seems like the first dead would knock out the second, but not the other way around; unless I'm wrong about how the second communicates via the first.

hmmmm, the FPGA simply act as a wire. pass the host data to the next one, and store-and-forward data to the host.

I have changed to queue miner and now get 374.25 +/- 5.93 MHash/s

I also get "upstream result: False" about every day and the mining stops --- I throught it may be my pc -- so I am in process of setting up a new pc to run software/icarus

I will run some traceroutes and ping test and post results and respond to ecki

the "upstream result: False" means stale, or just a wrong data.
miner stuck is a known issue, by my first plan, i don't want to do any fix on this miner, because i want to change to another common use miner software.
but looks like this progress needs some time.

我想请问一下张博士，这个用人民币买多少钱一个？本人住的离北航不远，运费可以忽略不计的，或者自己去取也行啊？

没有现货哦，目前订货状态，小批量大约3周。价格是3650￥。

为什么比用美刀买还贵啊？ Cry
