I haven't done it with this one yet but typically it's just a matter of using a router option to load a new firmware update where you substitute the alternate file. See OpenWrt docs, as it appears to be a typical case.

Awesome, So it's pretty damned easy and safe to flash these suckers. Only risk it seems is if your power goes out while flashing. Safe enough for me! I'll be getting one these for sure next month at 22$

I have some small heat sinks for the K1 now...

How much did those heat sinks cost you? I'm trying to figure out prices on the Nano for my assembly service, and I haven't seen much at all about heat sinks for the Nano.

Thanks!

I have a few different ones. A pack of 5 black ones 27mm sq. I got on ebay was around $5 inc. shpg. and they look ok. I also got some longer 1" wide that are plain Al and would be cut to length. I think they were around $3 for 2 pieces, and would be enough for 6 K1 when cut. And then I got some small Al ones locally that were also about 27mm sq. and were about $0.30 each. All of these may work ok but none of them are great looking.

One of these boys is on it's way to you


The holes are with thread M3
In this version with thread only it's more efficient ( it's  one operation less on cnc machine) to cut only 4 mm release for PCI-e and not full cut

Nice. Thank You. Will give them a good run-thru once I'm able.

They look like they would suck a lot of heat... +1 Marto. Same as your drawings right?

One difference only
The release for the PCI-e trough hole pins is 4 mm deep and not full cutout

Is the base the same thickness as before?

It's the same 5mm (5.2 mm actually measured)

At 33 Euros, it's hardly cheap and that's WITHOUT a case and power supply far as I can tell. It doesn't take too much CPU power to mine.

id rather go with a pi. Costs $45 - 50, but you have a device with 512 MB RAM. (~490 MB usable). You can put all sorts of things on it like monitoring, etc. Doesnt make sense to me to save a few bucks one would use 32/64MB devices...especially when this is a small fraction of the overall expense...

Perhaps talk of host machines is polluting the thread? This thread should be about Klondike ...

Maybe another alternative thread for everything non K1 , K16 board specific?

Heat sinks, casing, host controllers fans etc? Need a lot of info to gather in one spot for people like me that need all the help they can get on this DIY build.

That would be cool!
It would help me out, that's for sure, being sorta-n00bish.

Yeah.. i think we should not bother bkk with such trivial things as host controller. Perhaps hijack the case thread for the alternative purposes. host controller in fact is applicable to all DIY projects in general. AFAIK all plan on having USB interface. As far as Klondike is concerned i think bkk has made it clear that it will have USB interface, and it will be cgminer controled. So basically anything that has cgminer and USB is fine from perspective of Klondike.

http://squonk42.github.io/TL-WR703N/  <--- if you need Reverse-Engineering work on the TL-WR703N 150M 802.11n Wi-Fi Router. Imagine that mashup? K16 meets TL-WR703N?

I love it when people do that kind of thing. The funny thing is that all the Chinese sellers don't seem to know why so many people buy this unit. They sell them and apologize that the interface is in Chinese and provide a Chinglish manual. If they would just pre-install OpenWrt they could sell them for $5 more and everyone would be happy with the superior firmware in English ready to run.

Anyway, USB testing went very well this afternoon. I got it to immediately show up in lsusb and a udev rule gives it a symlink name, /dev/Klondike. I used gtkterm to communicate with the firmware and tested some  rudimentary cmds for fan PWM and temperature readback that worked fine. I was able to view the PWM output via Logic Analyser, and held up a desk fan to make the temperature readings vary a little. Tomorrow I'll burn the actual Klondike firmware and start using the actual protocol to view status and set config values. I should be able to get actual ASIC data push captures too as that has already been tested by chaoztc, so I know it works.

I also came across the Microchip Demo Project for usblib interfacing. I may look at switching it from CDC serial to that instead as it seems like it may give a bit more flexibility.

Oh! And just got an email that the first K16 boards have shipped today.

Sweet! Thanks for all the updates.

I gotta say, as an enterprise Java developer I get to know a lot of really smart people. But this thread is a whole new level! There's a whole lot of brain power and effort behind this thread!

Thanks again, especially to BkkCoins, but also to all the contributors to this project. Awesome job y'all, and VERY exciting Smiley

Hi BkkCoins,

I would like to ask for your opinion on BFL offer we got today at https://bitcointalk.org/index.php?topic=223571 .

They are willing to sell us (as GroupBuy) advanced 65 nm chips (4 GH/s per piece) on 100% escrow (John K.), on-time-or-deal-is-off policy.

Is developing and producing mining boards capable of running those chips more challenging than for Avalon's 110 nm ones? Would you be interested? (Avalon boards are surely to stay the top priority.)

Since, I'm refining the deal right now, I can use any suggestions about documentation, sample chips etc. I should require for you/other developers as part of the deal.

Thank you.

BFL haven't release any technical data on the chips as far as I know, so you would be flying blind trying to work out what's needed.

Dudes... PM stuff to him about BFL. Stop cluttering the thread!

This is for development of the Klondike boards not questions about BFL chip group buys. Such a snaky way to plug BFL crap in this thread stop it.

Sorry for the offtopic just wanted to throw this in to balance out the last posts about BFL bold emphasis on 65nm chips vs. 110nm avalon chips. Guy spammed same message to all the DIY thread.

Back to the Klondike boards.
