Steamboat already pasted Klondike project URL to LSD thread, but in case someone missed it, you can check it out at http://projectklondike.org.
And anyone running Klondikes, you can drop pictures of your miners to [email protected]. They will be added to the gallery.

Thanks for putting that info up Wink

I'll post my pics of my Klondikes after I clean up my setup Cheesy

Great, looking forward to it

Well, that kinda worked. I successfully programmed my 6 K16s using the PICkit 3.

The 3 that I'd gotten halfway working before now appear to be fully working, though I now need to address cooling. I keep getting "critical overheat" messages.

The 3 that weren't working are still not working. One gets 100% hw errors, one has a zero hashrate, and the third isn't even detected (I get "usb 1-4.1.4.4.4: device not accepting address 91, error -32" in dmesg, and the USB hub light turns off.)

I used 100% linux to program them BTW, no Windows, and it worked just fine.

Bogart, there is a failsafe in CGminer itself. Currently it is set to 53.5 deg C. You can change it to higher value in driver-klondike.c at line 63:

Quote

#define KLN_KILLWORK_TEMP 53.5

to for example 63.5 is what I'm using:

Quote

#define KLN_KILLWORK_TEMP 63.5

Then recompile.
Anyways, Kano is going to change that soon I think. We discussed it, but we didn't achieved consensus yet on which temperature would be the best there.

I just pushed up updated firmware with 333MHz default clock. It should be more stable at the start, so try that. Then you can use cgm config to clock it higher.

Stop using branwallets

Sounds like it's time to break out the oscilloscope.

Congrats !!!!!!!!!!!!! Cool

Good luck with those others Wink

You can download sources here https://github.com/zipiju/k16-firmware. For now just sourcefiles, I'll add compiled hex as soon as git starts cooperating with me

.

Thanks for all your hard work. Can you confirm the hex file at https://github.com/zipiju/k16-firmware/tree/master/Klondike.X/dist/K16/production is current. I got an abandoned K16 proto in the mail that I'd like to bring up to date.

Thanks,
Tom

Yes it's the latest working for now.

Think. Positive. Thoughts.

Does cgminer work with these in windows or only linux?

I went ahead and ordered a PICkit from a US seller. Hopefully I'll have it in a few days.

The pickit is really easy to use, pretty much plug and play.

Yep and someone could help out over screen sharing if needed. The problem might be the two weeks it takes to get a chinese pickit delivered, might need to buy a real one.

I already have a Bus Pirate, though I've never actually used it for anything. I don't know if it would work for this or not.

http://dangerousprototypes.com/docs/Bus_Pirate

I have an AVR Dragon also, and some Pis (thinking of their GPIO interface.)

The pic needs 12v to program it, you need an adaptor for the bus pirate to do this. You could build the adapter yourself.

Now I need to figure out how to get this firmware onto my Mitten Mining K16s.

The ones I that I have running (replaced C274) are only limping along around 2.5ghps now.

Where you located Huh

East coast US.

I'll check with Steamboat,maybe we can do something to help Wink

Give me a few days Cool

Can you get a PICkit 3 & would you know how to use it Huh

They're about $35 or so on Ebay,the red one is the one he uses.

I could probably figure it out. I do OK with things like this.

The problem is Voltage regulator from 12V to 1.2 V
2 x 16 A, so @ 1.2 V it is 38.4 W , so 2.4 W per chip max.
@ 282 Avalons are about 2 W
@ 450 Mhz our board is about 92 W so 5.75 W per chip i believe it's almost the same with bitburner

That is the limitation of K16

But if you have extra PCBs you can throw less chips in there (or beef up the regulator, I'm not sure what size the traces are you can check on the board)

I agree this is the best solution

I just received 50 avalon1s pretty cheap and pcbs are on their way. After I successfully assemble them, I would like to try out some overclocking, with extreme cooling (read: dry ice). Someone mentioned OC above, and was shot down. The K16 uses a standard PC PSU, so as long as one is used that can dish out the increased wattage, we should be alright with replacing the clock and lowering voltage resistors to the chips, right?
