I really think the metal shields inside the unit need to go. The beagleboard shouldn't get hot at all, I've run those things stuffed into little plastic enclosures in my car dashboard and never had one overheat. The shield in the back makes even less sense. Cyper, any update on what you are doing to manage temps?

Cyper, I don't think blowing across the unit will make a big difference if you close the case. Right now you are bringing fresh air onto that board. Why don't you just strap that fan onto the heatsink on the open side working with the other fan, or switch the location of that board to one of the front slots where they get cold air from the big fans on the front. Otherwise, you could always cut a big hole on the side of the case and mount it properly.

Avenger, I didn't notice you set me straight, all I saw was some lame ad-hominem attack from a sad little boy and didn't need to respond to it. From reading your posts i honestly pity you, it must be hard to live your angry life... You probably need to go outside more, get some fresh air and sunlight.

Bitcoinorama! Good to see you again. Any idea when tuning software will arrive for November units?

No idea. I'm in the US currently. Literally just touched down in SF after a few days in NYC en route to the Vegas conference. I do know that later firmware a will have a more intelligent code that detects which device you have.

Also there will be more upgrade boards at some point. The controller boards are essentially the same albeit firmware, but you need 4x Nov boards to run a Nov box, otherwise an Oct will be detected and limited.

Make my day! Say thanks if you found me helpful Smiley BTC Address --->

Damn, I should fly down to vegas to this conference! Too much going on right now Sad  
Can you explain the upgrade boards? November units don't have headers for extra modules, could they be soldered in and connected to make nice overpowered ones again? If someone with an october jupiter got 4 november modules, they could flash to november software and run faster, but what of the october asics? Would this be a replacement use only? How many total ASICs can one of the controller boards run ?

This.

I grew up during the beginning of the computer revolution. By comparison, from my observations, the KNC devices are free of defect. The early "consumer" computers did not function without tinkering. My first computer was an IMSAI Altair. I still have fond memories of that machine, even though my watch has a much more powerful processor now. But it was not "plug it in and it works". You had to have quite a bit of knowledge JUST to plug it in! And then you had to get it to talk to a terminal (Televideo 101 in my case). Then, if you wanted to retain any of your data, you had to either build a floppy disk controller or a tape deck controller on an S-100 template (or spend a few hundred 1974 dollars to have someone do it) by hand, build a cable to interface with the damn thing, and hope it worked. THEN you had to code in a bootstrap routine (again, by hand, often by punch card in those days, though I used the terminal). From there you could program in such cool things as terminal emulation, or get a C/PM OS which had it built in (but not the basic bootstrap, that had to be hand coded) and connect up to your high speed 140 baud modem.

It was a great time, despite how it sounds now. My ONLY problem with these highly experimental ASIC devices is that I couldn't raise the money to get one. If I had, I'd be having a blast tweaking it.

Let's face it, Bitcoin is in itself a grand experiment. It's as fraught with danger of failure as early computers. When I was a kid, mos people thought that computers were strange, and never would amount to anything. Now everyone has one and we live in a wired world. Bitcoin is where computers were in the early '70s. If it succeeds, yeah, there will be properly tested machines at walmart. But that time is in the future. Those of you who got in on it now are the vanguard. It may end in failure and ashes, but it might blow up the way computers did. Either way, you'll have one hell of a story to tell your kids. They won't believe you, just like my son don't believe there was a time without the internet or personal computers or CD's...

But you will know. And you'll remember the tribulations of the early days in a way different light than the current frustration. IBM, Intel and Microsoft didn't change the world, they just provided the tools. WE changed the world.

Miner in between 2 open windows + Open case + side fan.

I'm currently building this: https://www.youtube.com/watch?v=n_F83SbHMyg
So when it is ready I will have to move all the units to it and do something about the overheating board.

Hi CYPER,

very nice, what material are you planning to build them with?  Timber, MDF?

and also, what are you using to draw/design these 3D animated images?  Does the drawing package create the video?

I'd love to have a go at the drawing thingy you're using.  Very cool.

Thanks.

That program looks like Sketchup.  Pretty easy to use, i like it.

Tired of substandard power distribution in your ASIC setup???   Chris' Custom Cablez will get you sorted out right!  No job too hard so PM me for a quote

Better to give you the plans and help you build it yourself Wink

Thanks.

18mm MDF. Total surface area both sides is around 9 sq.m and total weight is 60kg.
Shelves are 60cm by 60cm and total height is around 1.40m. Each compartment is 21cm high.

Sketchup is the program - never used it in my life and after 2-3 hours this is what I made.
Very intuitive and easy to use Wink
Yes, it makes and exports the video.

Still a tough number to swallow.  If they were more open with (aka, had available) any realistic estimates for hashrate, power usage, etc., they would be sold out by now.  I have to agree with whoever posted above that for the price tag they haven't put enough info forth and have such a wide open delivery window this is more of a faith-based purchase than their first gen devices.  I believe in a lot of things, just not a mining company holding my pre-order funds for up to and including six months.  Been down that road, got lucky it paid itself off due to dramatic rise in price, but for $13k?  My group has the cash but nobody here is that much of a cowboy.

Agreed. Those complaining about Knc quality should go read through the Bitfury thread. Folks are doing all sorts of kludgy things to get their hardware to work properly, including putting packing peanuts between the h-boards!

https://bitcointalk.org/index.php?topic=251966.msg3802040#msg3802040

In my opinion, the Knc offerings are extremely well refined compared to ASIC offerings from other companies. I'm amazed at what they were able to pull off with such a tight schedule!
