[CLOSED] - Stumptown Miners - Avalon PCB Assembly - West Coast USA

[gateway]

I think rye is just setting up escrow so he can accept taking funds now, I'm pretty sure he's getting ready as bkkcoins is finishing up his prototype boards within 4-5 days.

Yep, that's the case. JohnK has my identity information and I'm currently working on a small website that will allow people to place their orders. There was a miscommunication between JohnK and me, though. The escrow we're looking at setting up will have the payments going directly to me so he doesn't have to deal with converting a bunch of XBT (I just discovered the ISO standards thread: https://bitcointalk.org/index.php?topic=179881.0) to USD all the time. If I reneg on our deal, then JohnK releases my identity information.

Is this an acceptable setup for everyone? The funds will have to pass through my hands and into the plants' hands at some point prior to delivery anyway, as I don't have enough funds on hand to pay for batches of 100 miners all by myself.

Have you looked on ebay for "4-layer PCB" printers? The prices and quality is a LOT better than most US listed prices. (Not for a prototype board though.)

I have no trouble believing this. In looking for a local supplier, I'm hoping to minimize turnaround time, not price. I'm going to be a little more expensive than most of the other deals, but I'm aiming to be faster in return. Time is XBT when you're mining.

BTW, im working on a website where people like you who are providing services can take orders for your product, track orders, send out emails or updates to status of users who have ordered, etc.. etc..

Let me know if interested, I have something working behind the scenes yet but haven't shown anyone.

I'm interested in at least 4 K16s, and a handful of K1s.

Ryepdx - PM sent.

预计K16价格：〜$ 93
预计K64价格：〜$372

[ryepdx]

The quote's in from Tate on the K1/Nano. It'll be $11.28 for assembly at batch sizes of 128 and $10.56 at batch sizes of 256. Parts for a batch size of 128 will be $5.48, plus shipping, which brings the parts price up to $6.44. (I'm allocating $5 in shipping for each line item.)

I don't have circuit board fabrication quotes for the K1 yet, so I'm going to use the 5 day turn around, 128 batch size quote I got on the K16 from PCB Unlimited: $10.07. I imagine we'll be able to get it cheaper once I get hard numbers, since the board's about 1/8 the size of the K16, but that's what I'm going with for now.

Not sure about the price on heatsinks yet, but the price sans-heatsink looks to be $30.57. I'm going to be looking at heatsinks for all the miners today and will hopefully have those numbers to add to the miner prices soon.

I'll also be looking at sources for cases and stacking solutions for those of us who need them. I don't plan on producing any myself at this point, but I figure it'll help to have a summary of the efforts out there here. And if there's any sort of bulk discount, we can pool our orders to take advantage of that. I won't be taking any sort of group buy fee on those orders, since I'm already taking a fee on the miners themselves.

[SebastianJu]

How big will the licencing fee for bkkcoins be per board?

[ryepdx]

Licensing fees were still up in the air last time I checked, but BkkCoins threw out $5 per board a couple weeks ago when we were PMing. I was planning on giving him a cut from my fee.

[ryepdx]

Alright, for now I'm planning on going with steamboat's heatsink buy. I'll allocate $6 per K16 for that. I haven't seen anything decisive regarding heatsinks for the Nanos yet.

[warhawk187]

Whats the update on the PCB development? Is this more of a BkkCoins related question? I on the fence as to go with ryepdx or burnin's PCB assembly. I would be interested in 3 K64s but would have about 8 chips leftover. I am on the east coast so shipping would be quick once assembly is complete, but not sure if the difference would be enough to change my mind as to build quality/warranty/turnaround time considering difficulty is up just 25% this round alone. I have two orders with zefir for batches 5 and 7, but have still not supported any devs until I see more tangible proof of completed PCB assembly. (I understand this is all speculation until Avalon actually sends sample chips to the devs for testing, but am just testing out the waters and these two projects have the best prospects for right now.

[ryepdx]

If you want to keep track of the state of PCB development, go read through BkkCoins' posts in the Klondike thread. Basically it sounds like things are going well so far. Heatsinks are the most unknown quantity right now. There have been a couple proposed heatsink designs, and BkkCoins has received a few samples, but he's not really going to be able to test them until he has chips. Right now we're in "wait and see and design cases and heatsinks" mode.

From reading the Klondike thread, it's my understanding that sample chips will precede the rest of the group buy chips by four weeks. We should have at least a couple weeks to react to anything unforeseen revealed by BkkCoins' prototype tests. I'm not too worried about BkkCoins' design working out, though. There have been a lot of eyes on it, and most (if not all, IIRC) of BkkCoins' assumptions about the design prior to Avalon's release of their specs turned out to be right.

[zefir]

Cross-post in all threads of projects that are registered for Avalon sample chips from my order.

Delivery of sample chips seems to have started.

If you have chips ordered with me that you want to support this project with, do it now.

If you are the owner of this project, please provide me your shipping address.


Find the details here.

[ryepdx]

Orders are now open. Go to www.stumptownminers.com to place your order.

Let me know if you have any questions. I'll soon be arranging a meetup in Portland for those who want to meet with me face to face.

[Kushedout]

Placed the order. Will send the BTC in few hours. 

Good job on the order form. Unfortunately I have chips coming to you from 2 different group-buys.
Hope they arrive at the same time. Also, where are you located, as I would prefer a local pickup.

Thanks, and good luck.

[evilscoop]

Love the site, well done....

Think I need to sort a site too soon

Thanks! For users with chips coming from two different group buys, I'll choose to either split the order up between the group buys or get it done with the later-arriving one. My criteria will be whichever results in more people getting their orders.

Also, where are you located, as I would prefer a local pickup.

I'm in Portland, Oregon.

Love the site, well done....

Thanks. If you want, I can let you use my code.

[ryepdx]

Okay, I'm organizing two meetups this week for those who would like to either place an order in person or just place a face with the name.

I'll be at the Green Dragon from 7pm to 8pm this Thursday and Friday. I'll be the guy with the "Stumptown Miners" sign on the back of his laptop.

Please let me know if you can't make either of these and want to place an order in person.

So this design will be based off BkkCoins Klondike Design identically? Who will be assembling the boards and what experience do they have with ASIC/FPGA technology? What is the expected turnaround time? Will there be any sort of warranty for this?

I'm almost at a decision, although burnin's seems the most informed thread out there for DIY designs. If you can answer these I would consider adding my chips to your order. I would be interested in 3 K64 units, however would have 8 chips left, would there be an option to buy out others leftover chips and assemble another K16 unit? Or I guess 8 K1 units? Feel free to PM me these answers as well, although I think it would get many more of us stateside interested simply due to faster shipping.

[ryepdx]

Yes. I am simply organizing the assembly of BkkCoins' design stateside.

Who will be assembling the boards and what experience do they have with ASIC/FPGA technology? What is the expected turnaround time? Will there be any sort of warranty for this?

Tate Tech will be assembling the boards. They were founded in 1992. Their CEO managed Key Tronic Europe's operations in Ireland in the 80s. I've been in contact with their VP of Customer Solutions and he's told me they can provide assembly with 3 to 5 day turnaround. I expect to add a day to that for PIC programming on each batch. PCB fabrication will take 10 days, but I expect to kick that off before the chips arrive. I also expect to have all the parts necessary before the chips arrive. I am shooting for 1 week turnaround.

I'm almost at a decision, although burnin's seems the most informed thread out there for DIY designs.

burnin is probably more informed than I am, since it sounds like he knows how to assemble the miners himself. I don't have that kind of EE knowledge, honestly. You should be aware of that.

...would there be an option to buy out others leftover chips and assemble another K16 unit? Or I guess 8 K1 units?

You can certainly arrange for buying out other people's chips. They'll have to speak up here, though, since I don't personally have any insight into that. The order form requires the number of chips pledged from a group buy and the number of chips required for the miners ordered to divide evenly.

Ugh, looks like subscribe to thread doesn't actually notify me of anything

Anyways, great progress!

Has it been settled on Steamboat's heatsink design?  I only ask as I'd be one of those looking for a chassis solution (either will make my own, or piggyback off someone elses project) that I can rackmount, and knowing the dimensions beforehand lets me start building mockups.

I'm also looking for 6 extra chips (assuming none of mine are DOA) from anyone who happens to have a few extra.  I'll pay above the price paid + shipping, and I'm sure we can simply let rye know to swap 6 on his end when they arrive.

Do you plan on keeping this open?  Or will this be a one-time group buy?  Sorry if this was already answered.  I plan on picking up chips if available after they ship from auctions and the like, so I need to line up options to get them turned into miners if that scenario plays out.
