Would there be any way to cut down box size as well?
If you can fit 20 units in a box and I only want 1 its a waste of shipping space. :/

Hmmm. Can you put one aside for me at that price then?
Could you quote 1 unit shipped to Canada?
I'm getting around 1 BTC if I factor in shipping as a cost.. Is this correct?
The price would be 1.0974BTC you can ship up to 20 k1's in the package. This is if you choose the ordinary package. I'm getting around 1 BTC if I factor in shipping as a cost.. Is this correct?

What is the shipping cost to Canada sir? Interested in 1 or 2 of these.
These are the shipping optionsEMS PRIORITY MERCHANDISE USD $23.48
EMS MERCHANDISE USD $20.43
Express Pack USD $52.80
Ordinary Pack USD $24.10

This is the same as the other usb miner.. no ROI. 
That is incorrect depending on how high you clock these you can get a ROI

I'm interested in a small number (2 or 3 perhaps). What is the postage to UK? Will they get stuck in customs?
All buyers are responsible to at least check with customs in their country regarding any computer peripheral devices like these USB miners.

I don't think it will get stuck in customs as it is a small package but I can not guarantee.

First 2 have been sold. Contact me if you are interested. These k1's will be more powerful then the Asicminer block eruptor usb and CHEAPER! These are capable of at least 400MH/s

I haven't seen it happen again after changing the USB cable to the high quality one from my Canon camera that has a ferrite core near the board connector.
I've wired in the inverters now. The signal has very sharp/fast rise times now and it's easy to see the clock delay is 50nS. I tested it manually in ktest and got all GOOD nonces up to 420 MHz doing repeat work filling the queue . At 430 MHz they came back BAD.
Unfortunately on cgminer the error rate hasn't improved. I haven't run that long yet but I'm seeing 3% - 5% error rates. I believe this is now related to noise on the PLL and instability. It can go quite a long time with no errors, and just when I think Ok, it's down to 1% now, but then a bunch pop up and it's back to 3%.
I'm moving onto final board revisions now. Hope to have a new K16 release later today and k1 tomorrow sometime.

so do you have these in hand
No one does.

Pentel Asks:
Any update on the Klondike K1 Nano USB Bitcoin Miner's?
BKK Responds:
I expect to complete a final revision of the board in a couple days, and then order a batch for final testing. The K16 has been verified and this is based on that, uses same firmware and cgminer driver, which are working, though quite basic still. Once boards are ordered I'll have time to polish the code and get a bootloader added (which allows upgrading via USB).
For anyone planning to use the board design for their own project / products, note that I will be changing it to the QFN version of the PIC and the parts list will have some changes.
The K16 has been running quite well for me in testing. The HW error rate is still a bit high and I think some board changes planned will help with that.

Our best hope will be Avalon chips arrive in 2 weeks or less.
We also hope to have Gerbers next week and pay for our Fabricator to source BOM 2 weeks.
If everything aligns properly then production starts 2 to 3 weeks from now.
That would be sweet... but luck would have to be on all our sides and shipping would follow the 24 hour burn in time.
Group buy is now OPEN
were would there be posted from ? and any idea on postage costs to the uk ?
Items will be posted from Indonesia. Not sure on postage costs right now as we are talking with dhl about that currently. We can definitely ship to the Uk though.so do you have these in hand
No we do not have these on hand as the k1 design will to be finalised for another 3-4 days and the chips won't come for another week. After that they go straight into production. So we should be ready to ship in 3-4 weeks.

PM'd !
so how much hash rate will it do
Chips rated 282 Mh/s. BKKCoins has 341 Mh/s as very stable 0 errors under prototype conditions. Likely 341 is not the upper limit for a K1 air cooled with a fan.

K1
Hashing @ 300 mhz
Hashing @ 350 mhz
We run it for short periods 2-3 min , because there is only heatsink
