[Group Buy#1] Avalon ASICs CHIPS! Using JohnK as escrow! FINISHED!

[Noitev]

I'm working with bkkcoins. if anyone in this early order wants to sell chips, i have 77 btc and I'll buy them at a small premium. want to have enough to provide Klondike-1s at a retail level

Do you have any idea what you plan on selling the Klondike-1s at retail?

Related; is anyone looking at assembling Klondike-1s for group buyers?

not yet, anywhere from 30-60. but really it comes down to parts (need chips!)

I planning on selling klondike 1s via retail, need chips though.

Willing to buy up to 750 chips (100 minimum) at 0.10 per chip. If you want an easy turn around and help me start my k1 retail idea, please help!

[Bicknellski]

Ragin... Can we please get an answer to what is going to happen with the developer chips?

[bigbeninlondon]

FYI

I am speaking with manufacturers to have heatsinks made for the Klondike board. Having heatsinks made is going to be less expensive than purchasing and modifying any current solution. I need to know who is planning on purchasing boards, what quantity, and whether or not they would want a heatsink.

Specs are:
100x100x25mm
3mm base
1mm fins
2mm spacing
6000 series aluminum
4 mounting holes drilled, located in center of each 4 chip group.
Flat base/underside

This is a one time deal. Enough heatsinks need to be purchased to cover all the boards, with a few extra. Purchasing additional heatsinks in low quantity will be prohibitively expensive. These heatsinks will not be made available to the general public. They will only be made available to those offering bulk purchasing as I cannot sell these piecemeal. I will be offering them as part of a package to those who purchase chips through me.

Group buy coordinators, Large private buyers, and Klondike resellers need to contact me ASAP.

Emphasis mine.

So I'm to assume that Ragin will / should be at the very least helping coordinate the boards (or choices for us buyers)? I want to get this going and covered before the chips start coming in.

[Lailoken]

Who should I talk to about getting the spreadsheet changed/my name put on it?

[Todamont]

Ragingazn, I remember you saying you were talking to BkkCoin from the Klondike thread about reserving boards. Would it be possible to coordinate so that those of us from this group buy who want to can get in on that order?

I'm technically *able* to contract and have my own Klondike boards printed, I need to look at what BkkCoin has released so far. Last time I looked it wasn't a complete design on github yet. Since I only have 70 chips though, it would be easier for me to just ride along on a bigger order.

If Klondike releases a full schematic and parts list soon enough, I can help coordinate having an American assembler on a just-in-time delivery schedule, for those interested.

Cheers~

Not sure anyone is getting or will be able to "reserve" places in the line... No indication at all how all this will work. Ideally people would be better off working on board fabs locally or through various suppliers in China and giving BKKcoins royalties for boards as I am not sure what sort of capacity he can take on and what will happen with ASIC chips etc. This is all pretty much up in the air.

In terms of heat sinks people need to slow down a tad on group buys for those considering BKKCoins will be getting a number of different heat sinks to test. I personally am shipping 4 different types of heat sinks to him for testing which are various heights and configurations. Again with that ideally the shipping weight of larger numbers of heatsinks or klondike boards with heat sinks would drive up the costs so getting locally available heat sinks is best and can be after boards have asics and are shipped then people can mount their heat sinks. Or maybe your PCB fab house could do the heat sinks as well depends on the distance of shipping etc.

Where are you ragingazn? been waiting a week to transfer rallye's order to me, have 55 btc in cold storage for this and was really hoping you could confirm the transfer to me...

was it on escrow?

[Kushedout]

Yes it was. However, JohnK (escrow) has made the payment. He has done his part.

Push come to shove, can we change the shipping address?

[John (John K.)]

I see OP online about 4 hours ago though - are you sure he's not here? 

[AMuppInTime]

OP - please update.

[Egon]

OP - please update.

Agree, this is what you are receiving the fee for...

[John (John K.)]

I've PM'ed him to ask him pop in sometimes.

Also curious to know the plan with the chips

My understanding is there are 30 sample chips for every 10k order, so every 333.33.. chips would get 1 sample chip, if divided evenly.

[ I think we don't want to go old-testament style "the chip shall be cut in two and each person shall receive half" ]

I've purchased 572 chips from batch #1 (252 from atcsecure, 320 from dserrano5, both transactions posted publically, confirmed by original owner, and raginazn himself)

I am an EE with access to a lot of nice test equipment and plan on having my Klondike-16 boards assembled by a local professional PCB Assembly (P&P + Reflow with Pb63Sn37 solder) company I've worked with and can get boards made very fast.  I'd like to get one or two of the sample chips to test and publish for everyone's knowledge the results of these tests before the full batches ship in July:

* The Klondike-16 design as-is (P&P files, Solder Paste locations -- especially the QFN pad, Solder paste stencil thickness, etc) as populated by an outsourced assembly house
* The standard functionality of the boards (with a single chip, my understanding is the design will work with any number of chips, might need to tweak the firmware).  Hash rate, power draw.  Power draw of ASIC at various clock and hash rates.
* Thermal analysis of the board.  With various heatsink, without a heatsink, with various heatsinks with poor mechanical connection (I'll watch the temp closely so it doesn't overheat and damage the chip), with and without forced airflow.
* Overclocking.  I can modify the design, change out clock sources, modify the settings on the PLL on the chip(s).  Am very curious to see what these chips are capable of with proper cooling.  I would not be surprised to see 20, maybe 30%+ better performance.  I do not think the current 282MH/sec is a thermal limit, but I can't know for sure until i can play with it.  Similar to thermal analysis, I'll keep the chip within acceptable operating range.  I don't want to blow anything up until we have a lot more information.  Especially with only the one chip.
* Affects of the above on the power requirements (increased current on the 1.2V line, perhaps above 2A/chip.  Possibly need for additional decoupling capacitance on the chips.  Oscope measurements, Spectrum analyzer (depending on if there is harmonics or noise coupling onto the Vcc plane(s)).
* After the above, some modifications to the design to support overclocking.  -- While at this time I believe there is a good amount of headroom on these chips, the current design, both Avalon's official reference and Klondikes, provides exactly the max current spec for the chips (i.e. 32A @ 1.2V for 16 chips, each rated for 2A max.)  I expect that OC'ing will push this beyond, something i'll confirm with power/current measurements when OC'ing.  (Will report Clock freq, Hash rate, Current draw, Temperature, Heatsinking methods used, etc.)


If i happen to get more than 1 (i have some chips in other orders), I will probably have multiple PCB assemblies built up, each with 1 chip.  This will help to verify a tiny bit better the yields of the assembly, which in theory should be very high.  But there would be nothing worse than suddenly realizing that 50% of the boards are scrap.  If i get say, 4, i will have 2x boards with 1 chip and 1x board with 2 chips made.

Of course we want to check to make sure that a board with say, 16x chips works of course. But i expect that BkkCoins will be getting several dozen chips from various people, so he should be able to take care of that.

I've PM'ed him to ask him pop in sometimes. 

Escrow has let him know via PM to touch base with us... this should be enough to get some action from him. There are certainly questions that need attention.

SORRY! Haha I've been trying to get things done in my new home. I'm totally here though

Relief!  Thanks for checking in. 

[Bicknellski]

Hope the guy who was whining gives JohnK a gratuity. Well deserved and yet again he goes well above and beyond the call o' duty.

Nah I was just really curious, want to transfer 592 chips to me and you disappeared right after I struck a deal. Hope the chips are being shipped to your new home!

When you get a chance, I hope you can confirm that Rallye still has 592 chips which he can transfer to me. thanks! and shoot me a pm.
