Klondike assembly EOI

I am looking to get around 37 Klondike boards professionally assembled in Sydney. At this stage I will be waiting on the final PCB design and BOM so I can get quotes.

If you are interested in adding to my possible order please post. The larger the run the cheaper it is.

I used to work in the smd assembly industry, admittedly that was a long time ago but it does mean I am comfortable getting this done.

Hi defkin,
I'm in Sydney and I'm getting 625 klondike boards done myself.
I have been waiting for a finalised design to go shopping around for an assembler but these guys look pretty cheap: http://www.tracktronics.com.au.
Dunno if it would work for us to buy together cos I'm looking to have the assembly done within 24-48 hours of receiving chips.
I think we could definitely work together on the heatsinks if you were interested.
Might be good to trade infos on different suppliers/assemblers though.
cheers

Hi all, I'm in for ten boards. Have been shopping around for quotes as well and waiting for results. Maybe get a group buy going for Australia residents?

Although I might increase the number of boards to 40. Heatsinks are a worry at the moment for me.

Hi guys.

I'm in Tassie.

Would be interested in some boards.

Could you post a bit more info on where you are at with regard to chips, design etc.

 And associated costs etc.

Cheers

Adam

I'm in Aus and would maybe be interested, however it will depend heavily on timing, cost and my disposable income at the time.

In Brisbane, I'll be interested and will keep a eye here for further details as they develop

Best price I can gather right now is as follows:
machine setup (per unique part): 25 parts (pls correct me if I'm wrong) = $100
PCB Load : $4 per board = $2500 (just for my boards, will be more including others)
Component placement fee, $0.05 per part x 307 parts = $15.35
Assembly Price per board = approx $20 per board + parts
would love to hear corrections or better offers...

Interested as well.  I'm in WA

Thats good, no heatsinks I assume.

interested however dont have any chips

In Brisbane, was keeping an eye out for complete board sales as l didn't order any chips, don't need cases or anything like that. Currently looking at Terrahash but anything closer to home is better.



625 boards seems like an awful lot, like over 2.5 Terrahash! When I started mining in 2011 I use to get ove 1 BTC per day on about $500 worth of hardware. I would have to spend  10 times that now to get the same using GPU. People are throwing annual salaries into hardware and the block rate says the same, the difficulty just goes up. My goals are a bit more modest, I am still happy with a BTC a day which is about 20-25GH/s worth of Klondike boards.

Hi I live in Sydney

are you going to sell some of your 625 boards ?

I'll be offering a group buy/service for a near turn key product.

I'm interested as well, can anyone supply chips or willing to sell me a few to complete a few boards?

I'm in Sydney

Hi emanymton

I can think of a few items:
The solder paste stencil
Through hole components
Cost/supply of components, the assembler should be able to supply all of these and depending on what their turnover is they could have good buying power. Tubed components we could supply and will for the avalon chip also they load one for one. Reel components on the other hand can add up on short runs, they are a bit like staples in that when separated from the tape are useless and depending on the machine a number are wasted when loading up.

I think we really need the PCB file and BOM for a comparative quote, what one company charges for assembly, another might make up in supply, and other in short lead times.

I have a few chips on order that i will probably get populated to a couple of boards through my group. Once things are more mature and i actually see chips coming from avalon and working boards the i will be prepared to invest further.

I would be interested in a group buy of chips and boards as things progress. I could be tempted into a few boards to hold whilst waiting for the next batch of chips.

I think timing is everything here. Where all gonna receive chips at different times making a single run not practical. However an aussie group buy from avalon followed by a board run would be an excellent idea...

I'm going to try set up a farm in some old server racks with all of them if possible. If it turns out to be too much to handle then I'll sell some of them.
It is quite excessive but I've been kicking myself for not getting into mining sooner and now's my chance.
If the k64 design is available by the time I get my chips then I'll be using that one.


I could possibly be interested depending on price, but I think at my volume it's gonna work out cheaper to do it myself.


Thanks for the input, everythings still very tentative till the design is finalised then I can start to shop around.
It'll be interesting to see how fast we can get these boards put into action.
I can't imagine the components being too much cheaper than mouser but would love if they were.
Hopefully the through hole components don't affect the overall assembly price too much.
If anybody knows any good assemblers or a place to get the heatsinks domestically I think we could all benefit.

I am going to be water cooling mine, I have not worked all the details out yet but it will be simple using off the shelf parts.
I have an avalon now and it puts out a lot of heat and noise.

Here is my initial idea. Its looking like I will need to make an adapter plate from flat bar and will mount broads both side of the tube.

Just an FYI ... I live in Sydney :)
So if you want to ensure continued support by the cgminer devs - ckolivas and myself - if you can provide one to each of us we can of course ensure we can provide proper and ongoing support for them.

The Avalon software is already under heavy development by ckolivas at the moment for the switch over to USB.

... and being in Sydney myself ... you can get one to me the same day they are ready and I can test and work on cgminer if required to make sure everyone will have it working as soon as possible if there are any problems then and in the future
ckolivas lives in Aus also

I like your idea, it looks to have a lot of promise, particularly for cooling as many boards as mine.

Is there a u-bolt that would suit the holes on the klondike?
Also would the fact that there is a through hole component make it infeasible for the klondike?

I don't quite understand what you guys mean about surface area.
Are you talking about the interior surface area that is in contact with the water?

Also instead of the nozzle, maybe you could consider something like this: http://koolance.com/dual-video-connector-adjustable-1-slot-spacing
Doesn't have to be that one, I'm sure there's standard ones you can get from a hardware store
All you would need to do is weld the cap on the end, then drill a suitable hole and tap a thread inside it.
I would trust a screw in, more than hoseclamps, even though the pressure probably isn't that high so it may not matter.
Also you could place the holes on the top rather than either end which tom_o was suggesting.


I would probably be agreeable to donating a board or two in exchange for some advice setting up cgminer on my host.
I'm a bit hesitant to make any concrete promises at this point though without even a finalised design.

Another chance of collaborating with emanymton?

I am in Melbourne, and I am looking at 1, maybe 2 boards only with assembly.

I might be, but it would depend heavily on timing and price.
The most important thing is getting my units hashing as quickly as possible.

True, but the most important thing really is getting the chips out of Avalon. Everything else is a pipe dream until they start shipping.

I've purchased 240 chips in an overseas group buy, so I'll be needing chip soldering and 15 boards.

If anybody would provide this service in Australia at a reasonable cost, I would definitely be keen to purchase.

No case necessary! I like to build custom equipment out of milk crates etc :)

I have given up on u bolts. The boards would have to extend 10mm past the area that needs cooling and neither board layout is doing that.
My work around is to use 3mm thick flat bar, drill and tap mounting holes then tack weld the flat bar to the rectangular tube.

The take offs could be a threaded fitting or anything for that matter. I prefer the clamp fitting over threaded as aluminum is not the most durable material and I would not trust the thread in so far as me accidentally stripping it. Using a more durable material is also out due to galvanic series.

Mounting the take off at the top. The positioning is not a big deal once the air is out but I was planning mounting on top to make it easier to bleed anyhow. Drawings are just to get the idea across not technically accurate yet :)

The surface area was for the inside. The more surface area you have in contact with the water the more heat is exchanged, The idea of the mesh inside was to increase surface area and turbulence.

This is a sketch of my latest plan so far, I plan on having the boards line both sides and that is another good reason to dump the u bolt idea:

Watching... good luck guys hope it goes well.

I am after assembled boards without heatsinks, I am going to work out my own cooling solution.

BKKCoins is going to do the develop of the mining software as part of the Klondike board right as open source might be better to support his work on this and keep your boards in your hands. Why not buy get your own Klondike and support open development for the DIYers? This isn't Avalon / BFL I think there are plenty of people who can develop and support software and firmware without having to give away any boards.

That looks really good. I'm going to seriously consider doing something like this for my boards.
Would there be a layer of thermal paste between the flat bar and the tube?

https://109.201.133.65/index.php?topic=190731.msg2243586#msg2243586

Check this out for those looking for firmware / miner support.

LOL you are funny :)
Just coz I like the BFL hardware you're trying to direct them to not support cgminer.
Interesting.
I guess I need to take a closer look at that thread ...

Dude,

Like what you want.

If you put in effort to the Klondike you are my best mate.

Other than that... why not order up a K16 and some chips and have at it rather than hat in hand?

I for one will contribute to you or anyone who supports a miner that works well with the Klondike and I will add that directly to the price of the boards if people want your version of "CGminer" It would be nice to see you involved in this Klondike all in rather than just waiting for a finished prototype etc as it is a very reasonably priced miner given what people have priced it at. It isn't BFL or Avalon you might actually get these in hand without delays.

CGminer doesn't require your support if I am not correct? Anyone can mod it right?

Quid pro quo... you show me what you put into Klondike and I will certainly put every effort in to compensate you any way possible.
 

@kano + bicknellski:

Chill out please.

If some boards are required for CGMiner support, some boards will be provided. It's all too early anyway.

No one is "due" anything but there is no reason not to facilitate the group effort nor to recognize the participation of individuals. Let's just not make this into sth it's not.

Pretty please?

Back to watching... good luck guys in Sydney.

I put Bicknellski on my ignore list weeks ago from his trolling in other threads.

I dunno, was what I said vague?

I certainly cant do any more than write the software after I get the device.
(or write something ready for me to test/fix if an MCU spec is written)
What were you expecting?

Also in Sydney.

I'm interested as well..but I would prefer the K64.

Interested and watching.

I am also considering parting with some of my chips after they arrive in Sydney. If anyone is in need of any, feel free to PM me.

Cheers,
QG

Likewise... troll.

Anyone got confirmation that their chips have shipped yet?

I might be willing to sell my Avalon chips, if anyone is interested send me a PM.

Not really on topic but not totally off topic either ...
I got a Burnin BitBurner XX (BTB) today and now looking at the option changes to Avalon to optimise the BTB
Running it without a fan (that I got some hours later) suggested some interesting code changes to avalon that may be required :)
(mainly disabling the mining all together when it gets too hot until it cools down a lot)
https://bitcointalk.org/index.php?topic=179769.msg2868183#msg2868183

It is good to see that the first BitBurner XX came to Sydney.

Let's see if you can replicate burnin's 9Gh/s with that board.

Well, this show has stalled with the multi-week delay on the shipment of Avalon chips, starting to be quite a controversy in other threads. If it all goes belly up, does one of the Bitfury based board designs look like a suitable replacement project to get build locally? Thinking about the S-Hash design in particular.

We've been talking about the Bitfury chip for the Caterpillar project - it's going to depend a lot on funding.

FYI all, Barntech is running a GB for BF chips.He's from Sydney. He's also got a modular board design to house them. Apparently he also has a USB design on the way. But still very limited details on design.

Dave from megabigpower has confirm Barntech got a test chip IIRC.

Cheers,
QG

Ah, that's about the best news I've heard in a while - do you have a link?

odd... I though I had linked it.

Awesome, thanks for that. Reading through the thread now.
