Klondike - 16 chip ASIC Open Source Board - Preliminary

[KS]

Interesting to look at the pics of the KNCminer boards in this thread:

https://bitcointalk.org/index.php?topic=214285.0

A lot less parts count than the Avalon or BFL boards. I believe it's the  6 GH/s device called Mars.

Different technology, different requirements. Could you not spam KnC stuff in this thread?

Full enclousure 8 x K16 with PSU and space for linux router

Neat... Do you have an off the shelf Mini ITX in mind? Or maybe BFL have a few left over cases they want to sell cheap considering they are not going to use them... just have to scratch off the old logo.

Might we just keep to the topic? Start a new thread to debate the pros / cons and observations of other builds especially those that could be scams.

Look very nice. I think here is many cases we can use.
marto74  if you change the  location PSU,  that will fit in mITX standard housing like Fractal Design from picture above.

PICs and other parts have arrived so I'm off to Bkk again in a few minutes.
Will be back Monday morning with my goodies for playtime.

Also, a good chunk of the firmware is written but untested. The work send/result receive code has been tested by chaoztc using 2 PICs. Mostly what's left is I2C chaining code. Right now sitting at 6811 code and 805 data.

For our more adventurous modders maybe this as well?

I like this case... was thinking off using it for a single GPU rig if i ever needed a proper case for it.

If you use raspi or linux router as the host, then fit more k16 instead of the motherboard. The sideways ventilation could be an added advantage.

Found some more info on GitHub in the commits tab.
"finished hash unit BOM"
It lists MB as magnetic beads quantity (11) 30 ohm at 100MHZ does not specify DC resistance.

That doesn't seem like much of a roll off. Most of the traces for AVDD on the K16 board are long enough that I can cut and patch one in if need be but I suspect it will be ok. No doubt the intent is to keep high freq. PLL noise from passing via the supply between the ASICs. I wonder how unstable it is and if it was put in out of necessity or just for extra precaution.

I think it was more of a precaution as long as you have that capacitor near each ASIC probably will be fine.
I would think about adding on next rev of the board though.

ask for help

i will try Make the USB PCBA but anyone knows if i made it, how can i use that device
need any firmware, driver or software?

or just plug & play with CGMiner.

Hey all; can we take the case talk to another thread please?  The wood case looks cool, but it's a little OT.

Complete miner
8x K16 stacked on 4 200x100 heatsinks with fans and enclosure

Looks like you're using SW? If so, would you mind sharing your part/assembly files?

Yes I'll send them to BKKcoins to add them to the project as soon we have a working K16 board.
I did already sent a sample heatsink for single K16 to BKK for tests

BKK is gone till Monday... not really at all off topic as people looking to squeeze the K16 into something and this can be part of the design process considering it is DIY.

Excellent. Would be nice to get some IGES renders of the PCB as well

Case design is totally a part of the topic I agree. But the problem is that its such a complex issue in itself that it needs its own thread. This thread is mostly used for technical issues regarding the pcb design alone. To keep BkkCoins from having to dig through 100 posts on case design its time to start a new thread. I personally wanted to wait untill I had something physical to show.

Agreed. Time to do that I guess.

+1

The case talk is interesting, but it DOES dilute this thread

I started a new thread here for case design brainstorming:

I'm excited to see what the community will come up with!

Just my two cents when it comes to racks, I have been eyeing the eurocard form factor and some racks designed around it. I especially like what this guy has done http://vincentsanders.blogspot.com/2013/04/when-you-make-something-cleaning-it-out.html

We have a new thread for the topic of case design.

From now on if you have a case design idea for the Klondike 16 pcb please post here:
