What about some performance numbers and info about your bitstream?  Did you solve the tx/rx issue?

kind regards

ok.
 what i want, is a switch without soldering ( maybe a pre-soldered one with 2 wires)  but i dont know even if it exists. i have splices, ferrules and heatshrink covers (dont like soldering)any idea? what can i do?



To start an ATX power supply are you do is short the green wire to ground. There are readily available solutions to do that.

Thanks to you both . That is what I did ( shorted green-ground) but I would like to add a switch like CAblez did but without soldering. ( maybe a presoldered switch or one with some kind of ferrules to crimp). do these kind of switches exist?

But dont worry too much my PSU has a big switch which i can use to turn off/on, and besides I`m thinking about buying any kind of atom, via nano or amd low power motherboard to install linux and cgminer on it.



I use this to switch on my ATX PSUs:
(which works fine in my case since I am not actually using any wires from the ATX plug)

I use a paperclip to short green to ground and a piece of tape to keep the paperclip from falling out. Simple solution that has worked for years running multiple PSUs per quad-SLI/CF rig.

You only need to short it to start it up, you dont need to leave it in there while its running.

If you remove the ground from the PWR_ON pin, I'm pretty sure it turns off the PSU. I don't have one to test on right now, but are you sure on that?

I'm pretty sure. I've started PSUs up to see if they're not fried due to their owner's stupidity (hate tech support, hate hate hate) and they stayed on until I cycled the power.

Just tested on 3 different PSUs, and they all turned off when the ground was removed.

All ATX PSU's that I have chance to play with, they turned off when I removed clip/wire.

Its the same thing with the switch I showed earlier, by turning the switch off the ground is lost and the PSU turns off.

Exactly. It is how the PC turns off in the first place.

Just came home today from a conference to find this waiting at my house:

First Cairnsmore1 In the Wild!

It might be a couple days before I can post performance numbers as I'm extremely busy right now. I'll post more once I have numbers:

Here are pics in the meantime (including unboxing):

Definitely a beautiful board, and I love the cooling solution! I'm curious though if the rest of the people that pre-ordered are going to get an e-mail telling them to pay up or what exactly is going to happen?

I can't wait to get mine. I bought simply to support these guys because I think they are the most professional players in the FPGA market. I respect many other folks here for what they have done, but I just believe these guys are going to blow everyone away once they get a handle on bitcoin specific development.

Besides, they said June and they shipped one before June 1st, that is service.

Update

Ok first units are out. The first few days will be a very slow build up so a little patience is required. We are aiming for most units to ship with at least with at least in-built programming if not some level of bitstream so we will take 1 or 2 days to try and get that right. This also happens to tie up with our proper packaging that arrives hopefully on Friday. If we miss shipping on Friday for any reason there won't be any shipping until next Wednesday because of the Queen's 60th jubilee public holidays on Monday and Tuesday. Virtually nothing, except having a good time, will happen in the UK on the 4th and 5th of June. So we will do our best to get a pile of units out on Friday.

We are also doing other activities at the moment which whilst mundane also that tie in with efficient shipping, product quality, and how fast our shipping ramp is. Those include designing and manufacturing some simple custom test equipment and even physically constructing the programming and test line in an organised fashion as opposed to a hap hazard bench usage. This includes the arrival and assembly of some new work benches which cross fingers actually turn up today. All of this will make our test much more reliable and less labour intensive and allow us to achieve the necessary throughput.

We are also going through the process of refining the test proceedure and training staff on how to run it.

So please bear with us through this short transition stage. We know that you are all impatient to get mining with the Cairnsmore1 and I think it will meet your expectations when your order actually arrives. After all it's only 40 days since we announced the concept and started work on the design.

If your order was initially indicated as mid-June, or earlier, you probably should have had a first unit shipment offer. If you didn't get that either contact us or/and check your spam folder.

For those of you further down the pre-order list we should a better idea on shipping dates in a week or so once we have bedded down the test and shipping line a bit. That put togther with assembly data and expected arrival of parts will let us define the delivery schedule more accurately. We will update everyone then accordingly.

What are people using to mine?

... does it work with cgminer as an Icarus? (i.e. as 2 Icarus /dev/ttyUSBx or 2 COM ports?)
the latest (a few weeks old) cgminer git pull I have up may also help with that if it's a different speed to an Icarus Rev3
(the new --icarus-timing option)

Though, the fact that it is 4 chips (and not 2) may? need some minor changes to cgminer
(if it doesn't appear to the OS as 2 tty/COM ports)
