Sydney - Klondike assembly EOI

[emanymton]

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.

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.

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

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.

[emanymton]

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.

[DobZombie]

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?

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 ...

[Bicknellski]

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?

[Bicknellski]

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

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?

[BitCsByBit]

Also in Sydney.

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

[QuiveringGibbage]

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,
