Payment made for 2xK16 and 2xK1s. Any way to see the numbers of boards that have been paid for?

I plan on first setting up a table showing the number of orders made from each group buy, and then later I'll probably update it to show how many orders have been paid for from each group buy.

Will the manufacturer you are going with be receiving test chips to replicate and test the Klondike design as well? Will there be any sort of warranty offered?

No, the assembler I'm going with will not be receiving sample chips to test the Klondike design. I'll be going off of BkkCoins' test results. As for a warranty, I'm not sure what Tate Tech offers. Most assembly plants will do rework for free if things go wrong during assembly, but I will ask them specifically about that.

So where do we tell our group buy organizers to ship chips?

I would imagine that they would probably deal directly with each other. I think John K acted as escrow for both ryepdx as well as Ragnazn (organizer of my group buy) so it should be relatively easy for them to coordinate. I just filled out the shipping info form for my group buy and indicated that I was having them sent to Stumptown. I don't know how everyone else feels but my preference would be to just bundle all the Stumptown-bound chips together in one shipment, overnight to Oregon, and share the cost between those involved (proportional to each person's share of the chips). Alternatively, ryepdx would cover shipping for that one shipment and each of us users would pay him our share (this way one person isn't delaying the shipment to Stumptown).

Ragnazn has created an order form. He confirmed that for the address field we can simply state "Stumptown Miners" as the recipient and they will handle the details on their end.

Ok.  Will do.

Also, ryepdx I filled out your order form, but can't get the BTC until a week from Monday.  I'm confident you won't receive my chips by then, so I should be ok, but how do I update my order form?  That is, how do I recall the previous form I've already filled out?

Any chance that paypal (yeah, I know) can be accepted for the assembly? Would you care to have that as an option? As much as I can't stand Paypal sometimes, it might be beneficial since most of the people who would be using it are stateside anyways.

If you're just talking about getting a payment address, the address shown upon order form completion will work indefinitely. You can even bookmark the URL if you want. The page won't go away or anything.

If you need quantities or something changed for an order you've already made and paid for, just email or message me and I'll be happy to make the changes.

No, I'm sorry. Aside from the inevitable chargebacks I'd have to deal with, I'd also have to worry about them freezing my funds indefinitely if I get any sizable amount of money coming in.

I believe I saved the payment address, but I can't be positive.  When I get home tonight I'll check, and if not I'll PM you.

Thanks!

I just got back a quote on turnkey assembly of miners at larger batch sizes. I thought it would be interesting to share with you. Lead time on the K16s would be 10 to 12 weeks, though, so I'm not going this route unless they can reduce lead time.

Full turnkey assembly of a batch greater that 128 of K16s would run us $80.16, plus the cost of heatsinks, screws, PICs, and the 4UCONN 10987 and 11182s, per miner. Batch sizes of 256 would get us down to $72+, and batch sizes of 512 would get us to $64.62+. There are also one-time costs associated:

Solder Paste Stencil: $220.00
Programming (their machines, not the PICs): $330.00
Methodization: $182.00
PCB: $600.00

Full turnkey of a batch greater than 128 of K64s would run us $307.85, plus the cost of heatsinks, screws, PICs, and the 4UCONN 10987 and 11182s, per miner. Batches of 256 would run $277.95+, and batches of 512 would run $250.11. One time-costs:

Solder Paste Stencil: $220.00
Programming: $1,842.00
Methodization: $182.00
PCB: $600.00

And a batch of 128 K1s would run us $16.88 (plus cost of heatsinks) each, with 6 to 8 weeks turnaround. Batches of 256 would be $13.44+, batches of 512 would be $11.50+, and batches of 1,024 would be $10.25+.

I sent back an email and am seeing about getting the price of fabrication and assembly split off from the price they sent back, and I'm also seeing if they can reduce turnaround time. I suspect most of the lead time in their quote is due to parts acquisition. If that's the case, I'm going to see if I can get ahold of the parts any faster than them.

K16-sized heatsinks run about $6 each from steamboat's group buy. (So that's $24 added to the price of each K64.) I've got 256 arriving in the first batch. I'm also going to see if I can get a local plant to fabricate the heatsinks. If we get enough overall orders, that might push the price down further.

I've decided to drop my fee back down to the 5% I was talking about when I first started feeling this out. And once again, any difference in the price you paid in USD via BTC and the cost of the miners plus my 5% fee and shipping (if applicable) will be converted back to BTC and returned to you once everything's been bought and paid for.

Also, I've begun ordering PICs. I have 90 in hand already and will be sourcing more as soon as possible. I'll also be talking wtih BkkCoins about alternatives to the PIC on the parts list, since it's obviously in short supply. BkkCoins was talking about using another, more available chip requiring a different mounting procedure, so I'm going to see if I can get more information about that.

Wouldn't a different mounting procedure require a different board?

edit:
Why not just order them?

Yeah, it would require a slightly different board. BkkCoins plans on making that design available shortly after he's finished testing the current design. I'm hoping to have at least 128 of the original PICs available for a batch on the off-chance that the other design takes longer than expected to be released. I already have 90.

I haven't ordered a bunch of those yet mostly because I haven't even sold enough K16s at present to make a full batch of 128. I've added tables with number of chips pledged from each group buy and overall number of K1s, K16s, and K64s sold so you guys can keep track of that stuff too. I'll also be adding tables that show the number of K1s, K16s, and K64s from each group buy (with and without K16 substitution where its been requested) later on.

The biggest group buy using my service right now is ragingazn's, and that one has a potential 76 K16s after substituting the K64s with K16s. I have 1 order from zefir's group buy, and 1 order from SebastianJu's. 2 from steamboat's, if you count my own. We need more people on board as soon as possible.

I plan on ordering 3 k16 boards.  What's the refund policy (chips + BTC) if this falls through and manufacturing/assembly never happen?

Thanks,
Dave

The refund policy is to send you back the USD value of the BTC you sent as BTC. (I am converting the BTC I receive to USD for holding.) If we don't have enough orders for a batch by the time group buy chips start to go out, then this enterprise will be considered failed.

We need to move quickly now, though, because parts are already starting to go out of stock at various vendors, and I don't want to start ordering any parts en masse until we've got enough orders to fill a batch.

I plan on ordering 2 k16 and 8 k1 (40 chips from ragingazn's group buy), but I'm going to wait until Monday or Tuesday when the btc price hopefully recovers. Weekends is not a good time to buy something with btc.

How much will shipping be to Canada?

Shipping depends on how fast you want it, of course, and the shipper you prefer. But USPS can ship that up to Canada for $20, assuming the weight is lower than four pounds. (That's assuming about 1/4" of padding on all sides is sufficient, of course.)

QQ: Relatively speaking, how skilled would one need to be with standard soldering equipment to fit Avalon chips to a K1 board?  ...if it is even practical...

Not sure it'd be practical! Most of the components are small enough that reflow is basically the only way to go, as I understand it. There have been people who've been talking about doing skillet reflows, but I personally wouldn't want to risk my Avalon chips like that.
