I WOULD TAKE wtogami's advice and UPGRADE YOUR SHIT before its too late
Well, my MacBook Pro is pretty high end, but I'll look into rebuilding locally to take advantage of the 64 bit libs. But what do you mean by "too late"?

Is it possible to use asic hardware to improve the performance of bitcoind? Say when it's downloading the blockchain and running all those sha256 calculations? Maybe we could use some of those usb stick miners for this.

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):

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,

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.
Thanks! I'll make that change in my branch.

With the power connector on the bottom of the K16 I have to lay the miners I have running on their side. I'm thinking about building a custom shelf for them so I can route power out the bottom. How is everyone else setting up their miners? How are the hosted miners physically configured? And is anyone successfully stacking their miners? Any pictures?
Thanks,

A single unit can hash at about 4.8 MH/s or so...
Is it really that slow? Or did you mean Gh/s?

With this exponential growth in difficulty lately I was wondering: Because the difficulty is adjusted each 2016 blocks and not some other measure of time, if there were a substantial decrease in network capacity wouldn't the blockchain get "stuck"? For example, say things keeps growing nicely and then the next reward split rolls around and half the miners decide to shut down their operations overnight because it's not profitable. It might go from 10 minutes to find a new block to 2 hours or more. Then it could take 168 days to reach 2016 blocks and have the difficulty readjust.
Is this a real danger, or an I missing something in the specification?
Thanks,

Re: [Work in progess] Burnins Avalon Chip to mining board service
I know what voltages the cables from the atx have. The only thing i dont know is if i can safely take a 5V and a GND cable from the atx and power the rpi through its pins with it. I dont want to break it and for sure im not the only one coming up with that idea. Unfortunately i only found people that created a usb-connecter to power the rpi with a psu.
Then check this out: http://potech.dyndns.org/Easy%20PSU%20for%20RPi.html
This confirms my plan, thanks
That's what I'll do once they arrive Be sure to use one of the +5V lines and not the +5V standby if you want the pi to go off when you turn off the power supply. Also, be sure to check the rated current output of the standby lines, it may be lower than the full +5V rail. You need 1A for the pi to be happy.

We've also tested the stacking design for those of you who have purchased more than one unit

How is the stack going to look with fans? Is there going to be hardware for that, or are we building our own?
Thanks for the update, Steamboat!

They have not, and will not, be sold to anyone else.
Thanks,
That's what I was looking for.

Sheesh... people need to read what he wrote c-a-r-e-f-u-l-l-y.
We are receiving orders from chip purchasers other than our own 6 batches, and will not be holding any components in reserve for those that have purchased chips from us.
Translation- if you have ordered chips and only chips, that does NOT reserve any other components for you UNTIL you order assembly. When you order assembly, you are buying those components at that time. His point was to light a fire under your asses to order assembly ASAP, not to say that he's going to shaft all his customers.
Give him a little credit, here!

I hope no one here is NOT giving Steamboat a ton of credit. And I agree with your assessment. But I'd really like to hear Steamboat say it himself.

...I'm slightly confused and worried...
Ditto. I've already paid for 6 boards and have chips coming from you and another source. Does this mean someone who paid for their boards after me could use up supplies because they got their chips first and thereby cause me significant delays?

How do I order chips from Zefir?
You can't. His group buy has closed.

Jay,
From my understanding on the product page:
Assembly Only: Klondike mainboard assembled together with separately purchased ASIC chips to produce the core of the Fusion 16. This option is recommended only for customers using one off designs of the remaining items necessary for a fully functioning unit.
DIY Kit: Similar to the assembly only option with the addition of a DIY kit of final assembly parts for those who enjoy putting things together. Beginner to moderate skill level required.
Full Assembly: A fully assembled, functioning miner ready to be plugged in and begin hashing. This finish level comes with the option of in house testing to ensure full functionality of the unit prior to shipping.
So Assembly does not include all the final items (heat-sink, etc) and DIY includes all parts, but not assembled. If they don't do a full assembly, how can they properly test the unit, which needs all components installed and assembled?
Secondly, why would you need to assemble yourself to be able to stack it? Was that stated somewhere in the BBK thread or otherwise?

It was all a little unclear to me, that's why I asked the question. In response to your questions:
I read the description in the OP and is sounds like the "testing" is a burn in that would require the heat sink and fan be assembled. I want to know if there is any testing done at the assembly/DIY level that at least confirms that all the chips are working at the most basic level. I would think you'd be able to do that just by applying power to the board.
As far as stacking goes, if you look at the rendered imaged of the stand-alone miner and that stacked versions you'll see that the fan is in a different orientation. That's what makes me think that the'll require at least some disassembly to stack.
Thanks,
-Jay
A quick question about testing:
I was thinking I'd get the DIY kit because I plan on stacking 6 boards. According to the OP and the website, testing is only available with the fully assembled version. Does that mean that there is no testing done on the assembled version that comes with the DIY kit? Is there at least some kind of confirmation that the chips are good? I've got a few chips in reserve, but I'd hate to have to round trip a board or two just because I didn't want to have to take apart the fully assembled kit to stack it.
Thanks,
-Jay

Re: [Ann] US based Avalon ASIC chips and assembly: 715 remaining
So, I've missed the June 30th deadline and will more than likely not have BTC to complete my order for a few more days. Does this mean I'm out of luck? Or just delayed? I'd like to know before I complete my order.
Thanks,
