Guess how many are on the K64!

~270-300$ per K16 ? How many chips in that board?

~270-300$ per K16 Sounds pretty boss considering how fast we will get the units compared to BFL's speedy production.
Considering how simple K1's seem to be, It's going to be pretty easy to push those little suckers out for around 20-40$ depending on who you go with.

I think i will put a notice that all prices of the offers are tentative because no one really exactly knows whats the endprice.

Can do. At this point, I suppose I'm fine with you putting the currently projected prices in with a "(tentative)" after them. The price can still change since the design isn't finalized, but I think we're now in a reasonable ballpark of what it'll end up being.

Let me know when i should put these prices into the list...

A new quote just came in from a plant in Washington. They're offering assembly for $45.33 on batch sizes of 128 with 3 to 5 day turnaround.  They gave the quote based on a previous revision, which was a bit simpler, so I expect the final price to bump up a little, but that's still a bit better than what Colin was offering for that same revision. (Though the batch size of 128 means I'd need to wait until I have enough chips in hand to create 128 miners at minimum, whereas Colin was willing to work with batch sizes as small as 10. Still, the proximity means in-person pickup would be pretty easy and fast compared to how it would be with Colin.)

I'm still considering looking at prices for renting my own equipment, but that's honestly a route I'd like to avoid if possible since I feel I'm much more likely to mess up people's miners than a plant that specializes in assembly is.

With the new quote, that brings the back-of-the-envelope estimated cost per K16 miner to $89. Since the K64 is just four K16s on a single PCB, I think $356 is probably a safe bet on the K64 miner cost, though (as with everything in this thread so far) that's still pretty tentative and assumes we run the K64s in batches of 128. (Probably not a very safe assumption, honestly. I'll get more accurate quotes once Gerbers and a BOM for the K64 has been released.)

I didn't request a quote from them on the K1 (I sent the RFQ before we'd decided to move forward on the K1s) but I'll request one now.

Still waiting on a quote from the plant in Corvallis and a plant in Tigard that was recommended to me yesterday.

I'd be interested in 3 of the K16 boards... and possibly some of the K1s  ( depending on how many chips get damaged  )

Yeah, it looks like I'll be offering the Nano as well. There's been enough interest. I've started looking for quotes on it.

I can be in for two k16's

any thought on doing his nano 1 usbs?

I have some extra chips for those if you are

Ah, that's pretty good then. With me, it's probably going to be about $20-$26 for parts, plus $9 for the bare board (if we use Colin's Taipei supplier), which comes out to $104-$110. A bit more expensive than yours. With the volume increase since he made his quote, I expect the price to drop, though I'm not sure how much. He doesn't want to give any more quotes until we've got the finalized PCB design and parts list.


No word on the K1s yet. I've finally got the specs I need to get a quote, though, so I'll contact Colin and see if he's willing to give us just *one* more quote.


True facts. To that end, I won't be opening escrow until we're closer to Avalon's projected shipping date.

I have 20 chips coming from ragingazn, so would like 1xk16 and 4xk1's.  Any word on the k1's?

> I guess the question now is, how much of a premium are you guys willing to pay for fast turnaround?

I guess that question is best asked right before the orders are placed, when we have a better idea what the difficulty rate is and what the time is worth.

I just talked to a local to me assembly guy, and his best price would have been $200 a board, just for assembly.

So, these prices are looking pretty good.

As for other factors, I'm still waiting on my 32 chips from Steamboat, but so is everybody else.

I'd be interested to see what he's doing for his assembly as well.

As for Terrahash...the jury is still out on that one...

best price ive got so far for europe version is equiv to 96$/board ~ + vat so call it 100$

looks like our pricings are coming out similar
Though mine include the assembler printing the pcb and getting the parts (but not the asic chips)

Met with the representative from the Corvallis plant today. Nothing new was said. They repeated that they'll get a quote to me at some point. I guess they just wanted to place a face with the name. :-/

Thanks. I'll take a look at both of your links.


Excellent. Much appreciated!


Both, basically. He wasn't on my radar until BkkCoins brought him up, and then for you to guess his name right off the bat...



Thanks for giving your endorsement, too. It's good to know I'm working with someone who knows his stuff. :-)


Oh man, I didn't realize he was that far away. Will still go with him if I can't find anything nearly as competitive, but dealing with someone so far away is bound to mess with turnaround. :-/


I'll definitely do that. It would be awesome if I could manage working with someone more local than Colin. I'm sure he's a great guy, but I'd really like to do face-to-face pickup to expedite orders getting out, and trying to cross the Canadian border with a trunk full of miners sounds like it could end up being a lot of trouble. :-3

Still waiting on news on the K1/Nano miner prices, I can wait till you can figure out who will have the cheaper prices for the K16's but don't wait too long! I'll be getting about 4-10 chips depending on prices. I hope I don't have to wait too long for Batch 3 chips..(should have gotten in on batch 2 but I wasn't sure about ROI/Production yet)

Maybe in a week or so we locals can meet up and chat over drinks? I'd be up for that.

"How'd you find him?"

Not sure if you're asking me, how I know him or how did I find his work!

Colin is on the local hackerspace mailing list and has answered various SMT questions from people like me over the last few years.  I got into a thread with BkkCoins about him being from BC and mentioned I had asked Colin about just doing my Avalon asics for me (I was thinking of hand soldering the rest but given they're 0402, seems unlikely).  I guess Bkk forwarded the stuff to you that Colin sent me - I pointed him at Bkk's threads and github.

So in summary, I think Colin is genuine person who is very helpful and seems to know a lot about SMT.  I've not used his operation for anything.  You can see some of his posts at https://groups.google.com/forum/?fromgroups#!searchin/VancouverHackSpace/colin$20fitzgerald

Unfortunately he is located about 11 hours drive east of here in Kimberley (north of Montana, not north of Washington) so visiting him is not really an option.  I am hoping to meet him in a few weeks at the local Maker Faire.  I suspect his location makes him somewhat competitive (rural areas have lower costs).  I also suspect that since the business is fairly new he might be more available.

One other thought, have a chat to Paul from pjrc.com, he is OR based and seems to have a lot of experience with SMT production houses.  I worked with him years ago on his mp3 player, a smart guy.
