Maybe burnin could ask for the batch and orderplace in this within the orderprocess...

Hi Burnin since you'll be launching soon the ordering website I'd like to suggest a way to avoid and ordering/preordering/chip-batch matching mess (like what happened with KnC).
All chips come from batches and all batches are time-stamped so once you figure out which group buys are interested in your services, it should be very easy to organize a queue based on batch ordering date. It'll make sense for example if you open orders by turns to specific chip-batches based on ordering date, instead of opening for everyone at once and flooding the website and having to match orders to chip batches afterwards.
For example you first open order books for Zefir Batch 1 from April 16th (assuming this is the earliest one) for like 3 days or so, then you open order books to the next batch based on ordering date, and so on and so forth...

I love that brand name 
Just got my PSU, how is that for grunty connectors 
So a switchmode power supply (12v DC @ 5A) should power a 10 chip device easily?
Is the dc plug socket 2.5mm and can you tell us the polarity?
I'm on the hunt for a PSU

aww yiss
@burnin... i shipped 20 sample chips to you... Ill send you a pm with the trackingcode.
https://bitcointalksearch.org/topic/m.2452212
Ill send you a pm with the trackingcode.30 samples were delivered... 20 samples are on its way to burnin... Unfortunately i was 2 minutes too late at the post counter so it will be taken tomorrow from that branch. This way sending via express didnt make sense anymore... so it should be with burnin the day after tomorrow...
I worked with antistatic workspace and pincette. I really hope i did everything correctly. Ill post later some pictures of the chips. They are really awful tiny.
The other chips i will package today after checking back with zefir.

Awesome news!
Now to the bad news:
I hadn't really anticipated chip delivery this week when I ordered the boards, so they are still in production at my PCB manufacturer.
They should arrive next week though.
I'm might do initial tests with a single chip in dead-bug style for uC firmware verification in the meantime.
Sorry, I can't read the whole thread. Are you selling the PCB kit or just offering the assembly?
I do offer unpopulated PCBs but those don't include the parts. You'll have to order them yourself.
What's the timeframe looking like these days??
So far Its looking like I am on schedule to begin delivery in mid July if everything works out as planned.
Sure, I understand the role that the heatsink plays ;-), I just explained myself poorly! The heatsink still needs to heat the air around it in order for this warm air to be carried away by the airflow from the fan. Since the airflow wont be perfect, why fight any natural convection by having the heatsink upside down? I'm sure that you're right, it's not going to be a problem with 40W of power per board, but every little helps right?
actually this is not right as it was said the heatsink is the dissipation device where the cool air dragging the heat elsewhere, you don't have to heat the air more than cool the heatsink.
I think we're all saying the same thing actually, just in different ways. To cool the heatsink you need to heat the air passing by it - 1st law of thermodynamics. This is way off topic, I'm going to shut up now ;-)!
The advantage of heatsinks is, that the heat can spread through the aluminium and then be cooled by the airflow of the fan, and therefore does not have to "rise" upwards ;-)
So i think the effect you mean should be minimal.
The "rising upward" does only appear, when air is heated. It does not occur, when heat is spreading in a soldid material.

The original Avalon Design was for nearly perfect airflow, actually.
Great stuff, thanks for the clarification!

Hopefully burnin can give us news next week
Looking forward to the first tests!
excellent!
please give us updates burnin - i hope all goes well!

Check out my sig... there you can see all options and prices burnin is offering. I believe he sells the pcb only too.
What's the timeframe looking like these days??
still not selling 
wasnt end of may the wonder date?
no hesitation here, he isnt selling until he has a working board. wasnt end of may the wonder date?Jump to:
