roomservice, I know how the board was intended and read everything from the beginning.
I am in no way saying that enterpoint is not doing a great job...

I will try further, maybe i am just too dumb, at least with the drivers you can get to the board

Please read the opening post of this thread and rethink your statement. Everyone who ordered a board for initial price know about the fact that no benchmarking and no mining software would be available from the start.


yohan and his team doing a great job

Received my board. Sounds like it is a pretty paperweight for the next few days   Looks good though and I look forward to getting it up and running, even at only 50 MHz.

Yohan, thanks for the driver, but I cannot get it to hash with normal cgminer and the com ports (icarus detect: failed to open com 20). At least something.

The thing is: bitcoin mining is a race. And if I do not drive at all, that is not good. I calculated getting the first board and hashing the shipping cost until more boards arrive. Even slowly would be good. I do not see a slow bitstream as a fail, I see a board shipped via express not hashing as a fail.

Not major fail, as the hardware seems fine, but not a minor fail..

(should we open up a cairnsmore "sofware/bitstream/support" thread and keep this clean for hardware/shipping development?)

Any other cairnsmorer luckier than me?

Yes that's all they are. Nothing complicated.

It looks like in those pictures that the UP/DOWN connectors are just two row 0.1" IDC connectors. Is that right?

The USB drivers are now available on http://www.enterpoint.co.uk/cairnsmore/cairnsmore1_support_materials.html.

We are expecting tomorrow, or Friday, to make 2 CGminer extensions available. The first runs the 50MHz build over 4 FPGAs. The second uses only the first 2 FPGAs with an Icarus bitstream at 190MHz so more or less standard level performance on 2 chips.

Also aiming for tomorrow, or Friday, is our VM front end that will be used for the programmer function.

drivers? The FTDI driver from the chip manufacturer's website did not install. I have something here that is kinda bored

 

There is not a defined limit but something like 10 units is reasonable unless maybe you are an earthquake zone. Of course if you are next to a wall you could use an an angled bracket at the top to steady the stack. Or use something like a mechano bar with holes across the top to brace to the adjacent stack. The whole arrangement is very flexible and what works in your space.

We still have to add the up/down logic function but that is coming after we make headway on the hashing and clear the initial drive/software bits. The up/down can be used over multiple stacks. Just needs a longer ribbon cable to take the end of one stack to start of the next and you can run your entire rig on one USB cable. That is the plan.

Picture is simple stacking where units are literally just stacking as they come as standard. Taking off the fan assembly allows side blow configuration that can use the up/down in the same way but board spacing can be tighter. It's not set yet what spacers we will support but a total height step of 40mm would fit nicely with 120mm fans in push/pull configuration. That would use 2 fans to cover 3 boards. 40mm would say allow 20 boards in a stack without being silly. Stacks of 10, 20 maybe 30 boards also line up well with high power ATX PSUs and our plans for a power distribution board.

At the moment power usage is very low but that's meaningless until we get hashing rates up.

Any results on power consumption at this point?

OooOOoOoO   NOW I get it. Awesome.

EDIT: I see 9 in the top stack, what's the maximum? Also, what is the maximum stacking cable length? Because once you get above so many, you have to start over on another stack.

Sorry guys we got abit distracted on something else today so drivers and software not quite finished.Meanwhile so eye candy showing the main parts of simple stacking.

^^ I put my guess to a worker from UK as I can feel the hair on the ground plane it must have come after the copper and before the solder resist, it crosses data lines to one fpga though. I think the electrons flowing will not care

EDIT:

You guys are probably working a lot for the drivers and something working. I am hot for anything, even 10 MH/s also willing to try under windows and ubuntu and soon on openwrt with a TP-link router.

Nom Nom Nom

If it's under the solder resist, it would have come from whoever their PCB manufacturer is, not someone from Enterpoint. You probably have some Chinese factory worker DNA there.

I think I have the DNA of one of enterpoints workers. I think i have a organic/technical FPGA Hybrid Board

on the bottom there is a little hair under the "lötstopplack" (solder resist color). As far as I can see there should not be a electrical problem (hopefully).

I think I will clone that worker, and let the clone manufacture the boards for me

lol that's great.

I just peed myself a little bit.

I heard you like Cairnsmore Boards?

Unboxing Video:

The most professional Unboxing VID EVER!!!

+1 to both of these

+1 for extremely fast shipping (though express was a little to quick if the drivers are not out)

and a request for eldentyrells 3rd party firmware.

i believe you guys can do a bitstream similar powerful, but how long will it take? Would be fine, if we could use eldentyrells tricone firmware for the time before? Maybe also eldentyrells firmware shows how powerful your board is, as the bitstream does not work that good with the "lower"powered ztex boards.
