I'm think chriss99 in UK could make use of those sample chips. He just posted board pics but he has a shortage of sample chips for testing. If there are any sample chips in USA I would be willing to buy/ship them from Houston. Nice to see a few different board options coming along.

I must say that MrTeal is really nice... He was ready to send us chips to help when it looked like ours are stuck in US... But it was only tracking... Received my today and say thanks to him just to find out he had things ready to send me samples...
What's the rush? Chips won't be delivered until late September at the earliest.
I am a cheerleader for Lucko, MrTeal and chris99. Would be nice to have more than one option for BFL chip boards if possible...

Time to market is everything IMO. Why do an 8 chip board instead of getting this 4 chip design production-worthy? Seems to me that the 4 chip board that you already have would be production worthy sooner.
Thanks for the update, looking forward to hashing demos soon
That 7905 is going to be a big negative....
.
You should consider using something more sturdy than those flimsy semiconductor things....

LOL good plan 
So you stopped burning 7805s now? Awesome 
I went with the 7905 since the number is higher. I think the 7805 is last year's model.

(Just kidding, translation for the non-geek, 7805 is a linear power regulator that you'd never use i) Since 1990*, ii)for anything more than an amp iii) if you cared about conversion efficiency .... *okay, they're maybe still handy when you just want something quick and dirty.)

Another quick update. I've made some good progress on the DC/DC converter, I think most of the issues are now resolved. I'm now going to start tweaking the control loop and doing some load and transient tests at which point I can finish that part of the circuit for the final design. Meanwhile, work on the firmware continues.
i would laugh so loud if BFL will deliver chips on time and go over avalon
I am guessing they will start with 1 month delay, then 2 week delays, with 2 week intervals
Today, BFL doesnt seem to be able to produce chips fast enough for their own devices. I feel it may be a miracle if they can ship the chips in time. But, if they can ship, then chip projects would produce products quicker than BFL and that may anger their pre-order customers...It's more of a delay than that - BFL is quoting 100 days from order date to delivery. In BFL time units, that's around February 2014.
Awesome - will watch it too as we have 128 chips ordered.
Watching - If your successful perhaps you could get BFL to transfer my orders over to you. 
Sorry for this mini threadjack, but is there anyone still buying BFL chip credits? I'm trying to get rid of mine for like $10. Send me a PM so it doesn't interrupt the thread.
a) this really isn't the place for this and
b) the going rate is much much less than that...
EDIT: Unless I misread that, and it was supposed to imply that you're selling multiple credits for ~$10, in which case that's about right if the number is >4

Well this seems like an interesting project so will observe
Bet you guys will be faster than BFL at their rate
I wish you the best of luck on your progress and will be watching as the milestones are reached

I am under the impression that delays there are due to other part supply and assembly issues.

Sorry for the lack of updates, I was in the mountains and out of easy internet access over the weekend. Testing is still underway, and coding/testing for all the peripherals is in progress. Most of the low level ASIC code is done and looks good on a scope, so hopefully we should be fully hashing and tested this week, and get the 8 chip board out to fab so it can be built and validated for production.

Oh, I know. It would just be too spectacular for words. I'd hate to see it only because of the amount of great work put into the Klondikes and the whole Avalon-chip open source infrastructure, but, increasingly, team Avalon needs a good, solid, Fuck You, and I can't think of one with more iron-clad irony that that.
