Unfortunately I don't plan on selling any chips as I have no surplus to sell.


Sounds great! PMing you now.


Much appreciated. :-)

Look a couple lines down from your post, to where it says "ASICMINER Blade Sales."

Here's a link, nonetheless: https://bitcointalk.org/index.php?topic=204030.0

ASICMINER.

The one I'm currently quoting only offers a 30 day money back guarantee by default. I'll send them an email regarding rework and let you know what they say.

Just got off the phone with the Corvallis-based plant. They'll be coming up with some pricing charts and getting them to me later today or tomorrow. They're sending someone out to meet me face-to-face, too, tomorrow. They stressed how important it is to have large batch sizes, which is quite true. If you're in a group buy, and particularly if you know some of the other people in your batch are in the Pacific Northwest, then see if anyone else might be interested in a high-price/low-turnaround solution. The more people involved here, the cheaper it'll be for everyone.

I got some more quotes from the currently-cheapest plant for low numbers of PCBs. This time I figured in panelization and got some slightly lower prices for fabrication. Assembly prices are still really high, though.

Updated local per-board fabrication prices for the K16:

Qty	1-day	2-day	3-day	4-day	5-day	E Test
16	$129.09	$82.71	$69.46	$59.53	$49.59	$200.00
32	$66.39	$43.20	$36.58	$31.61	$26.64	$280.00
64	$35.35	$23.76	$20.45	$17.96	$15.48	$440.00
128	$20.83	$15.04	$13.38	$12.14	$10.90	$760.00

And updated per-board assembly prices for the K16, using leaded solder:

Qty	1 day	2 days	5 days	10 days
16	$471.44	$332.98	$297.33	$274.18
32	$450.34	$315.01	$280.92	$259.33
64	$439.80	$306.02	$272.72	$251.91
128	$434.52	$301.53	$268.61	$248.20

And now introducing K64 fabrication prices!

Qty	1-day	2-day	3-day	4-day	5-day	E Test
4	$516.35	$330.85	$277.85	$238.10	$198.35	$140.00
8	$265.57	$172.82	$146.32	$126.44	$106.57	$160.00
16	$141.41	$95.04	$81.79	$71.85	$61.91	$200.00
32	$83.34	$60.15	$53.52	$48.55	$43.59	$280.00

And K64 per-board assembly prices... :-p

Qty	1 day	2 days	5 days	10 days
16	$1,759.19	$1,224.09	$1,090.86	$1,007.64
32	$1,738.09	$1,206.12	$1,074.46	$992.79
64	$1,727.55	$1,197.13	$1,066.25	$985.37
128	$1,722.27	$1,192.64	$1,062.15	$981.66

I extended this out to 1024 boards, just for fun, and there's not much of a price break there beyond what 128 costs. With K64 batches of 32 and four days total turnaround, that would put the cost-per-board for fabrication and assembly at $1,286.27, before parts and my service fee. $358.21 for the same figures with the K16. So I guess the question now is, how much of a premium are you guys willing to pay for fast turnaround?

Anyway, I'm still hoping the folks in Corvallis can help me bring down the price. Right now I have pretty high hopes for them since they've been the most responsive and personable of the companies I've contacted so far.

I've also sent out requests for quotes to a few Washington companies, one California company, and one Arizona company. (The appeal of the last two being that they have plants in Mexico, which may provide a much lower price while still being close enough for me to do in-person pickup.)

Again, this is all tentative. Once I have quotes from everyone I've contacted so far and some finalized price charts and turnaround times put together, I'll see about getting escrow set up (hoping for JohnK or someone of similar standing) so people can start putting their bitcoin where their proverbial mouths are.

Escrow details

• The price per board will start pretty high and then drop as people ante up. Any overpayment caused by drop in price or rise in the value of bitcoin after you buy in will be returned to you upon production of your miner. Beware, though: if the value of bitcoin falls before the escrow can be released and converted to USD to pay for fabrication and assembly, you might end up owing more.
  
• If you have a special request regarding the size of the batch you want to be put in and how long you're willing to wait for such a batch, or if you want to pool your group buy chips with the chips from someone else's group buy, let me know and I'll try to work with that. The default batch grouping will be by group order batch, since I should receive those all at the same time, and processing in that way minimizes turnaround time.
  
• The escrow will be released to me when it comes time to manufacture the miners. (I don't have the funds to personally cover the cost of getting all these miners made.) Whoever holds escrow will also hold my personal information, to be released if I make off with your bitcoin.
  
• Escrow will not be available until all domestic pricing charts and turnaround times have been finalized. If demand results in enough miners being ordered and paid for via escrow to exceed the numbers in the pricing charts, I'll get additional quotes to cover the new requested quantities plus some buffer room.
  

I'll also see about getting offshore production quotes together so we can talk about possibly switching to those pricing models and plants in the event that difficulty skyrockets enough to negate any earning advantage resulting from the quick turn-around offered by domestic production. Of course, if the whole thing falls apart at that point, then I understand: my value proposition is quick turn around by using domestic companies and face-to-face hand-offs whenever possible.

For those of you holding out for the K1: I will be gathering quotes and taking orders for the K1 miner as well once the BOM and Gerber files are released.

Catching up on responses to comments I missed earlier:


Ah, right. That makes sense. So... maybe Canada will be the way to go. I tried emailing him, but the address on his website didn't work. I'll see if BkkCoins can give me a working address.


No. I basically just gave them the number of SMD, through-hole, and QFN components, along with the number of BOM line items. Some of the other plants (like the one in Corvallis) have required Gerbers and a BOM, but not the one quoted here.


Maybe. Terrahash, the other US-based distributor currently making waves, will have the last two advantages as well. I imagine turnaround will be faster with me, but how much faster is the vital question here. As difficulty goes up, the advantage to be had from moving quickly begins to weaken, until eventually cheaper with longer turnaround is a better deal. I intend to keep price charts going here so we can figure out the best deal for all involved.


Thanks! Sounds good.


Nope. I split the two phases of PCB construction into two tables. The top one is for fabricating the bare board, and the bottom one is for placing and soldering the components.

5.5 Gh/s with 7 6990s. $325/month in electricity, about 7.2 BTC gross a month. (~4 BTC profit per month, at current prices.)

*Stumptown. ('Tis a nickname for Portland, my hometown.)

And thanks for aggregating all this information! :-)

Exactly. The only scenario in which I buy the set from BkkCoins is the one where they get dev chips far enough in advance of the rest of us to allow receipt of that set before I start receiving Avalon chips. I will be paying BkkCoins a licensing fee.


They don't. The prices and times quoted are for assembly and fabrication only. I still need to price out parts. I have a call with a promising Corvallis-based plant in about two hours, and I may be able to get some firmer prices from them. (They specialize in end-to-end PCB construction for startups.)


8 K16 boards, not panelized. I wanted to err high in my initial estimates as I'd hate to over-promise and under-deliver. And the turnaround time for assembly is after the boards are done being fabricated. I intend to begin fabricating the boards as soon as BkkCoins confirms the design with a prototype, so we may gain some time there. (Depends on how quick BkkCoins' turnaround is.)

Seems that way right now. Again though, nothing is fixed yet. I still have a whole state full of plants to get quotes from. And I'll be on the phone with one of them at 3pm PST, so I'm pretty optimistic about that.


I ship the miner back to the owner. No plans for hosting as of yet. I might hash something out if there's demand and I end up having enough time.

Please note that my prices are not finalized yet. I'm releasing quotes as I receive them.

Yeah, I've seen that. My value add is getting the boards sooner than you'd be getting them with Terrahash. It'll be more expensive, but you will be mining sooner. Particularly if you're in the Pacific Northwest and can do a face-to-face pickup. (I know the thought of my complete set of 8 K64s, or 30 K16s, going through the mail makes me nervous.)

About to. I imagine it will be as well. I saw a couple plants that said 16 inch boards were preferable, so I'm guessing that's the size of the stock material they're working with. I'm going to run some different numbers through the online quote forms and compare the K64 to the K16, and then look at whether the K16 can be panelized and broken out later for greater savings. (I was running quotes for one PCB per array, as I wanted to make sure the price erred on the high side.)

I'm also expanding my search out to include plants in Washington today. That may turn up a cheaper option.


Well, a little more than $312. I haven't really priced parts yet. The parts, according to the BOM, would be about $26.32 per board. But a couple days ago I did some shopping around and there are some snags the BOM doesn't call out that bumps up the overall price. All the assemblers I've found so far require components to be on reels, which requires either buying enough components for a couple hundred miners or paying the supplier a $7 reeling fee per BOM line item. There are also a couple components that only come on reels of 5,000. (Those ones are only $15 for a reel of 5,000, so it's not too much of a price bump.)

Alright, BkkCoins has verified that I was giving the correct numbers. Here is the cheapest price per K16 board I could find for assembly in Oregon:

Qty	1 day	2 days	5 days	10 days
8	$513.63	$368.91	$330.14	$303.86
16	$471.44	$332.98	$297.33	$274.18
32	$450.34	$315.01	$280.92	$259.33
64	$439.80	$306.02	$272.72	$251.91

And here are the cheapest prices per K16 board I could find for PCB fabrication in Oregon:

Qty	1 days	2­ days	3­ days	4­ days	Electrical test
8	$266.52	$150.82	$121.89	$104.53	$196.33
16	$142.89	$80.76	$65.23	$55.91	$196.33
32	$81.08	$45.73	$36.89	$31.59	$196.33
64	$62.52	$35.08	$28.22	$24.10	$196.33

As BkkCoins said to me, "No wonder iPads aren't made in the USA."
I've got a couple of requests for quotes currently out, too, so I'll let you guys know if any come back with better prices. Tomorrow I'll take a look at prices for assembly up in Washington and start looking at part prices.

EDIT: BkkCoins says they know a place in Canada that offers $75 per board assembly. Going to be checking them out and then seeing if I can use their quote to knock some of these quotes down a peg. Hoping I don't have to cross national borders to get this thing done, but I'll do it if I have to. I've driven most of the way to Canada in a single day before, and that was without an early start.
Anyone know the laws regarding taking electronics back over the Canadian border?

Agreed. I plan on posting "batch size and turnaround to price per board" tables once I get verification from BkkCoins that I didn't mess up the specs I was getting quotes with. To minimize the amount of time people's chips are waiting around for chips from other group buys to arrive, I'm thinking of basing batches on group buys. And if a person is in a group buy that's not sending many chips my way, they can opt to join up with a larger, later-arriving group buy in order to get a lower price-per-board.


I know that feeling. I'll make sure to ask about error rates while shopping plants. I don't think it'll be very high for most of them, but I don't expect it to be zero either. There *is* a plant I'm looking at that offers conductivity testing on their boards, and another one that offers more in-depth testing. Both are pretty expensive per board, though.


Agreed.

EDIT:

Excellent. In that case, we can arrange a face-to-face pickup if you'd like. That'll save you some shipping time and expense.

Hmm... why is there a GPU missing? And 90c is a lot hotter than I like to keep my cards. I've heard 80c thrown around as a good rule of thumb for keeping your cards from getting damaged. But then again, most of my involvement in the mining scene was in early 2011. (Not rich, unfortunately. Stopped mining for most of 2011 and all of 2012 for various reasons.)

+1. BkkCoins should definitely get a few, at the very least.

Ordering has ended. PCBs and components have been bought and received.

I am currently offering refunds of $45 per miner, for those who want out.

Current projected throughput is 100 K16 miners completed per day once the test board issues have been figured out.

==========

Terms of Sale (formerly at stumptownminers.com)

                        

• You will supply your own chips.
• You will tell your group buy organizer to send your pledged chips to Stumptown Miners.
• The price of the miners you have bought may drop due to more people from your group buy joining. Any price difference in USD between what you paid and the new price will be sent back to you as BTC.
• There is a batch size minimum of 60 from each group buy for each design. If you order a design and there are not enough orders of that design from your group buy, you may either receive a refund or (if you are part of an early group buy) opt to have your chips lumped in with a batch from a later-arriving group. You must make the election to either have your chips lumped in with a later order or receive a refund at the time of purchase.
• All received BTC will be converted to USD to hedge against market crashes. (This step is necessary as the assembly and fabrication plants do not yet take BTC.)
• Refunds will be calculated according to the USD value of your BTC at the time of currency conversion. An equivalent amount of BTC, calculated at the exchange value on CampBX, will be returned to you in the event of a refund. (E.g., if BTC doubles in value against USD after you have paid, and you then receive a full refund, you will only get half the BTC you originally paid.)
• Refunds on any of the miners (K1, K16, and K64) in your order may be requested until orders for that particular model of miner from your group buy (or from a later group buy, if you've opted to have your order bumped rather than refunded) reach 128. I will begin ordering parts for your group buy's orders at that point and will no longer be able to fully reimburse you.
• You will be contacted via email for your shipping information once production begins. I will also arrange at least one group meeting per group buy for those of you who live nearby and want to pick up your miners in person.
