Hi Augusto
Are you in a position to place the order for the third batch tomorrow as originally expected?
Not entirely sure why the second batch was restricted to 80 units as the original indication was that anyone ordering and paying before 03-Jun-2013, but assuming you have good reasons for it. Just hoping the third batch doesn't fall through due to lack of sufficient interest/payments..
Thanks

Received my sticks.
Thank you so much, Augusto. I left positive feedback on your trust page.

Received 10 black in color miners today. Thanks A+C.
I think maybe he got all black. I bought directly from friedcat and happened the same to me

Received 2 of my units today, they are working great on raspberrypi with minepeon 
They working just out of the box? You do not need anything to upgrade? Can you explain more please:)1. plug the miner into a powered usb hub
2. configure pools on the web interface of minepeon.
3. modify /usr/lib/systemd/system/bfgminer.service add this to start options "--icarus-options 115200:1:1 --icarus-timing 3.0=100 -S /dev/ttyUSB0 -S /dev/ttyUSB1" (this is for 2 devices)
4.reload systemctl : systemctl daemon-reload
5.start bfgminer : systemctl start bfgminer
6.maybe cgminer was started automaticaly, stop it : systemctl stop cgminer.service
I was having trouble getting my pi to run. I tried all the editing, demon reloading and everything, no dice.
I noticed there was a new version of MinePeon dated 7/6/13, so I re-wrote my SD card with it. It worked straight away with no editing, just the pool addresses. I assume it is running cgminer as it says it is loaded in the scrolling startup text.
http://mineforeman.com/minepeon/ has the download link for the "Erupter Bob" version. "Butterfly Bob" didn't work for me.

Do you mind sharing what make/model USB hub you used?

Yes, 3.2.1 does improve hashrate slighty and you don't have to specify the devices or Icarus options. Sadly, with rPi, mining ends very soon and all devices are shown as zombies... works on Debian though. Waiting for new version of cgminer
June 08, 2013, 03:23:07 PM
I finally managed to get cgminer 3.2.1 to work with Debian 7.0 !
Her's what I did:
sudo cp cgminer-3.2.1/01-cgminer.rules /etc/udev/rules.d/
sudo service udev restart
Now unplug and plug again the usb erupter.
Restart cgminer and it should work.
cgminer 3.2.1 no longer requires to specify the serial device, nor any icarus timing options. I also read that it should improve the hashing rate compared to 3.1.1.

I've been trying to use:
--icarus-timing short
instead of:
--icarus-timing 3.0=100
It seems to be giving me a little more speed: about 335 MH/s instead of 334 MH/s
These options are explained in the file FPGA-README in cgminer source code.
The "short" options basically finds the timing by calculating it and periodically adjusting it in the first hour it runs. You will see a message in the log about these adjustments every once in a while if you try it.
The "3.0=100" is probably a safe timing that works fine for every unit. The thing is that all sticks are not exactly the same and some units might be able to cope with a slightly better timing value.

For those who received it, did you have to sign anything when you were delivered?
I used my office address, which is closed on Saturdays, and the tracking tells me it was delivered today. That leaves only two options, someone at my office is working extra today and signed for it, or they just dropped the parcel in the box without anyone signing for it.
Thanks for your answer!

When it was delivered here I did sign, the airsure sticker on the package however states "No sig req"

Also got 3 of 6 yesterday. Working great, thanks A+C.
Running them with rPi and powered USB2.0 hub. They do seem to generate some HW errors, but doesn't seem to affect hashrate. I have a fan blowing air over them, so the aluminum heatspreader isn't too hot to touch. Don't know about the little chips on the other side, though...
When the last 3 arrive, i plan to attach them to a large heatsink i have, which has enough surface for all of them. This will require extension cables for the Eruptors, but that doesn't seem to be a problem as i mined few hours with all 3 on different length cables (longest is about 2 meters long)
Then again, they mined equally well without any additional cooling, so i'm wondering what the thermal specs of these actually are. But extra cooling will give always mean longer life span, so extra cooling it is.

I received mine, it's working great 
Thanks Augusto! It's funny to see such a small thing almost outperforming my GPU

I was thinking of something that clamps on the back and on the chip and extends a way out would be ideal, but I have no way of fabricating this. There is not much room between mine in the tower style hubs I bought.

I notice that the square chip closest to the LED is the hottest. Are you planning on sticking the heat sinks on this chip, or the heat spreader on the underside?
Both front and back if I can.
For the moment I stuck 4 of this little square copper heat sinks on the back plate, but the thing is still too damn hot.
I'm planning to remove them and attach a spare i5 heat sink I have lying around, problem is the 2 screws on the back plate don't let me place it properly, but I'm thinking of a solution.
The i5 heat sink I have is about 10cm wide and looks like this: http://www.ayagroup.com/images/D/E41997-002_2.jpg
See what I mean? That should take care of it right ?? ;-) It's so big that should be all right even as a passive cooler with the fan off.
The chip closest to the led is the one marked with "BE100" and it's the hottest because it's the chip that does all the hashing work, as it was also mentioned in a another thread.
It will sure be nice to stick a heat sink on that chip, the problem is that it is so small that those copper heat sinks I have might not stick to it firmly. And if for some reason it detaches and touches other pins on the board it might short circuit and burn the whole thing, and I don't want to risk it. If I find a smaller heat sink I will do it though.

I'm thinking of getting some good copper heat sinks to cool it down and maybe reduce hardware errors.
