Thanks again BKKCoins.
Can't wait to start producing these in quantity and shipping them to people.
Exciting times.

Howcome there's no metal plate on the bottom to let the heat out? Seems like that would limit the overclocking potential.
Dude really?
Just read back just 3 messages. What do you do just look at the pictures?

Ok good deal, just wanted to be sure.
Thanks for all you do!!
Thanks for noticing that. I need that kind of scrutiny because when you work on it all day it's pretty easy for things to slip past you when you click the last few buttons to output files. The more people check over, and query any weirdness, the more likely we'll end up with perfect functional boards. Thanks for all you do!!

Looks great!
Where are the thermal vias on the back of the board??
Good question! I didn't even notice they weren't there. I better go find them Where are the thermal vias on the back of the board??
edit: Just checked again and the vias never show up on the renders, and on the gerbers only in the drill file (and some islands on internal layers). So that doesn't appear to have changed.
You had me worried for a minute there.
They should show up on a render though, but if you look carefully only the vias that have islands to exclude the layer show up.
Looks great!

The "Final Beta" Revision of K1 has been pushed up to GitHub.
List of Changes:
1. Added Dual NOR gate and Inverters from testing on K16 to improve result capture.
2. Changed PIC to use QFN version.
3. Added 2mm holes for fastening heat sink.
4. Made both LEDs flashable under software control for better blinkies.
5. Added thermistor for sensing temperature.
6. Fixed issues with buck regulator traces.
7. I2C chain conn. now non-thru hole pads - fits 3 pin header.
8. Added ferrite beads to ASIC power and USB signals.
9. Added another PIC decoupling capacitor.
This design should be checked over carefully before ordering boards based on it. Due to the many changes it should be treated as a new board.
I am initially only going to order a short run of these boards to supply current web store DIY orders and my own initial testing. This "Final Beta" board will be WHITE.
PIC QFN parts are in short supply right now. I have a limited batch coming to me already and have sold about 1/3 of those via web store pre-orders for the pre-programmed PICs.
Here's a render of what the Beta White board could look like:
And the back side - for those who want to know where the LEDs are. Actually I think the back side will be white too.

You can get them for 0.8374 BTC 
"Competitive" indeed.
Send me one tomorrow?
You make a great point.
You are therefore no longer competitive.
How are you going to be competitive I wonder?? 282mh/s mining against 100gh/s??

K1's? You cannot "get then [sic]". You can only pre-order them to be delivered at a much later date. Tell me. What is your guaranteed delivery date?
3 weeksIn those 3 weeks BE's will mine about .2 BTC which makes their effective cost .69 BTC. Way cheaper than yours.

Come on guys - Bicknellski already stated that the price was set to be 'competitive with' the Block Erupter. If the price had been set to be (cost + reasonable profit + 0.02BTC for BKKCoins), it would almost certainly be a good bit lower.
I don't begrudge them making some BTC, but I was disappointed that the 1st OSS incarnation was priced to be competitive with the predatory prices we have been getting from ASICMiner.

I am not trolling I am annoyed.
I don't deny anyone the right to make a buck. This is a OPEN SOURCE project. So it shouldn't just be competitive it should be a considerable savings. That is really the end of my commentary on this.
If someone wants to send me details on where these boards are being made and who to contact I would be happy to have them manufactured and sell them at a more reasonable price.
I won't hold my breath for that data however.
How about ~.3BTC?
You can get them for 0.8374 BTC
Block Erupters are BTC0.89 now quantity 1
You can't get a K1 (quantity 1) for BTC0.89 can you?

Nice try deleting my comment in your propoganda sales thread. Here it is again so everyone gets a chance to read it without your censorship.
What a shame. BE's are available today. K1's aren't. You aren't competitive. Drop your prices by at least 30% because by the time you actual have a product to ship that's what they'll be worth.
WTF. Really? Price: BTC0.99 1-9
10 or more BTC0.89
50 or more BTC0.79
Also no it is not the highest price we could have chosen. We are trying to price these to compete with asicminer
