I just submitted a pull request at GitHub for a fix I made to the klondike driver in cgminer.  It was incorrectly reporting the target fan speed on the status line (always 0% due to a math error).  Here is the diff if any of you adventurous souls out there want to try it out:

https://github.com/LiveJay/cgminer/commit/0124217db80cd4506d4fe1c921a6fd49bba59efb

Now it looks like this (it's capped at 99% because there isn't room for a fourth character):

https://photos-3.dropbox.com/t/0/AABLHwHkiYxSag3F8H6E3NUiyuUxGv8kqWewpDi4MHqkDA/12/44288815/png/1024x768/3/1384027200/0/2/Screenshot%202013-11-09%2010.25.55.png/eip0CZO0no5uOh5M9nwMA62GLBvLG4MNn1qJHuyykIE

My question is this:  The firmware aways seems to be returning 255 or 100% for the fan target speed, even when the fan is obviously running slower.  Is there any current activity around this in the firmware?  Is the firmware source available for review?  And where are the firmware devs hanging out.  I wouldn't mind listening in or helping out.

Thanks,

-Jay

For whatever reason, my klondikes say

KLN2 went idle before work was sent

over and over again.

No idea what is going on, using CGminer 3.7.2

Huh

Fantarget was dropped in latest firmware and cgm driver, since there is a temptarget. Because of compatibility with older firmware, the fantarget is set by cgm driver to 255.
If you want to monitor an actual fan speed (or current pwm level, since fan rpm measurement is not implemented in firmware yet), you have to take a look at klninfo->status[dev].kline.ws.fanspeed variable.
You can review K16 firmware at github.com/zipiju/k16-firmware.

Thank you for the suggestion Zipiju, I had thought that only applied to raspberry-pi, but I tried it, and it did help quite a bit, on Linux, where I can compile it easily.

On my windows machine, it's another story, but it seems to be working ok.

It seems if you add too may K16 too fast, cgminer gets confused. Best to add them one at a time, while keeping cgminer waiting on hotplug. At least, that works for me.

True, kinda forgot about it :S.
Can I solder the replacement part (Dead Bug Style) on the board? That way there is no need for a total PCB replacement.
For MLC1260-401ML, which Mouser has 50 in stock.

Depends how perfect you want it to be. The pad widths are about the same, 2.7 vs 2.8mm.
The pad lengths are slightly larger, 4.0 vs 3.1mm. But the spacing between is 4mm instead of 2.4mm.
So to make that work you would scratch part of the board area on the side away from the buck reg. so that it has more exposed contact area. It's 12mm instead of 8.6 so you would open up about 3mm. Do that and cut the stencil a bit and then you can paste as usual, but clean off any paste on the inner edge so it cannot contact the wrong terminal. Not even very messy really.

I ended up buying this replacement part. Has anyone else successfully done the swap? I am confused how I should properly install the new part. It has 2 leads, while the original 38L361C has 3 leads. Do I short the two on the left-hand side of the regulator?

EDIT: After looking over the data sheets for the 2 coil designs, I see that the 2 pins on the same side of the 38L361C is the coil, and the 3rd pin, opposite 1 and 2, is a ground. Is this correct? If it is, it would appear that the replacement coil should sit between the 2 contacts on the same side. In reference, I'm asking about parts L1 and L2

I went ahead and ordered the correct part. Anyone selling prototype stencils? One board /ea?

That's where I'm getting my prototype stencils : http://www.pololu.com/product/446
If you're in a rush - $50 and they can overnight it, or $25 and get it next week.

Does anyone have 10 x MCP16321T-330E/NGCT-ND they could sell me? PM me your price with rush shipping to USA-Arkansas, 72118.

Try here:

http://ca.mouser.com/Search/Refine.aspx?Keyword=Voltage+Regulators+-+Switching+Regulators+1A+Synchrouns+Buck+Switcher+24Vin

FWIW -- shows some stock.

I keyed in the description rather than the part number

Alternate packaging and one-offs appear to be available.

You can check the other sites yourself.

I realized that we have a laser cutter on the production line where I work, we use it to print metal nameplants. I'm going to cut my own stencil for free, rather than pay out the A** for one made.

Try Colin at placedroid.com, he's been assembling miners, also sells stencil making as a service.

Guys, I think it's amazing that this project is finally off the ground and working. I'm just sad I wasn't able to turn all these fancy parts in my office into miners...

I have a question. At what point do we give Bkkcoins a scammer tag? I hate to even suggest it as he gave a lot of his time to get the K16 95% finished before the chip debacle. I was with him the whole way and even sent him beer money so he could buy the equipment he needed. The fact stands that he still has 8 of my bitcoins, and everyday it's more and more obvious that he isn't returning. Other avenues of contact seem to have failed. How long do we give him?

Is he even alive?

No one has been able to contact him and he has not surfaced anywhere. Again maybe the people in Thailand can do more digging on this and see what is going on. Someone needs to do some proper investigating into this in Thailand not just some calls to the numbers... but actually checking out his residence and with the people he has had contact with in Thailand. I got no response from calls, emails, postcards... at this point someone needs to take this to the next level and physically track him down.

I don't feel comfortable with tagging him as a scammer. Also I have no evidence that he intentionally did what he did - there are other plausible explanations.
I have also provided him various kinds of support ($, btc, etc) and I have no intent to do a chargeback on those - he did a lot of work and I feel that he has more than deserved my contributions.

I agree.
For this, I posted a thread in "Local - Other ":
https://bitcointalk.org/index.php?topic=336079.0

Maybe post there what you tried, i.e. postcard with no reply, phonenumber disconnected or similar.
Also, a rough area where Chris lives would be nice to post there!

I am currently trying a number of emails to the local PCB fabricators in Thailand, that he suggested to me as alternatives to China and Indonesia and asking them that if they see Chris to contact me. ... long shot.

I don't think scammer is appropriate either, engineering is not cheap, his time was worthwhile.

I think it  would be nice if he came back and continued on with the project using the 2nd gen chips.

Please someone locate him.
It just doesn't make sense.
To pour that kind of energy into a project and then just disappear like that?
It doesn't follow.
