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.

I'd be interested in this as well.

Of course, there are a lot of things we still do NOT know, like when Steamboat's batches of chips are coming in (I have some on order with him), as well as what assembly prices and timetable will be.

More importantly, I'd like my chips to not be messed up in the assembly process, because they're a pain in the behind to get.

But, fundamentally, people working together to achieve common goals is a good thing, since we all want the stinkin' miners ASAP, heh.

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.

More importantly, I'd like my chips to not be messed up in the assembly process, because they're a pain in the behind to get.

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.

But, fundamentally, people working together to achieve common goals is a good thing, since we all want the stinkin' miners ASAP, heh.

Agreed.

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.

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:

Qty1 day2 days5 days10 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:

Qty1 days2­ days3­ days4­ daysElectrical 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?

Ouch! Pricey! Consider me another Portlander that's interested, Alto I don't have any chips yet I'd like to spend about 1.5-2BTC on some K1 miners.
Gunna see if I can find a group buy soon or maybe someone who has extra chips.

Another Oregon-er, but not (recently) from the metro area.

My interest is potentially conflicting somewhat (explained below.)  I am interested almost exclusively in the K1 USB style units.

My interest is mostly political (in a Bitcoin sort of way) in that I feel it would influence Bitcoin to remain more 'peer2peer' if the barrier to entry for mining were as low as possible.  People who are participating as non-commercial miners are not going to wish the solution to grow past the state where they could realistically mine.

I believe that individual users already overpay for bandwidth which they do not use, and the power costs for a small efficient rig would not even factor into most people's economics.  Thus, widely distributed mining may be competitive with commercial operations which do need to factor in power use as a major cost of operation.

So, I would be interested in any leads you may turn up in terms of local manufacturing and would certainly make an attempt to compensate for any effort it might save me.  Or if at some point you wish to and are able to coordinate such an effort that might be interesting to me also.  Secondly, if anyone else reading this might be of a similar mindset as I, I would be interested to hear from them.

Even if you (OP) are interested in a project along the lines of what I am talking about, I would not waste to much time on research.  It is more likely than not that I will lose interest.  But if you are talking shop with any leads and the conversation comes up, I'd be interested to know what you/they think.

We are a free trade zone, here in North America, built and assembled should be duty free.  Call up customs, they are very helpful with this.

I will check in my neck of the woods. Guess if we got 64+ boards together it might be ok, but....it's still pretty pricey.

I was hoping to keep the unit cost under $150 for assembly....

Did you just give them the parts list off GitHub and they gave you a quote based on that?

I can't open Klondike's CAD files off GitHub.

What will you save on turn around time waiting on Chinese PCBs?
What will you save on import duties?
What will you save on shipping inside the US?

I bet the costs of all that when you consider putting the product in hands faster negates the higher production costs. At this point the first products to ship are really the ones that are the "cheapest" because if they are hashing you are getting ROI.

GOOD LUCK! I hope it works out. I am trying to do that here in Indonesia ... still waiting on pricing for the boards here based on BOM. I will let you know how it compares here.

Oh and I think you have to EDIT the table.... both prices are for the K16? The top one is for K64 right?

Wow, that's extremely expensive. Did you get a quote for the K64 as well? That might be more affordable on a chip-per-board level.

So I'm looking at around $312 per board (4 day/5 day choice) if we have at least 32 PCBs manufactured and then assembled, correct?

16 chips at 282 MH/s = 4.512 GH/s.  My end cost for chips is currently $9.42 each (.08BTC) so a K16 would end up being $462.72. That doesn't seem too crazy if my math is remotely correct. AM blades are selling for 50 BTC each at 12.89 GH/s.  Of course by the time chips are here it could be a completely different story.

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.

So I'm looking at around $312 per board (4 day/5 day choice) if we have at least 32 PCBs manufactured and then assembled, correct?

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.)

TerraHash is assembling 64 chip boards for 1.99 BTC (around $230.00), and the 16 chip boards for 0.75 BTC (around $85.00). Definitely worth checking out.
