[Auction] Avalon Gen1 clone hardware - 16 complete "barebone" units available

[ShadesOfMarble]

I'm auctioning Avalon clones, i.e. all parts necessary to build a total of 16 Avalon units (4 modules each), except for chips (ASICs) and the ATX power supply.

That includes:

• Cases
• Finished boards: Control Unit, PDU, Backplane
• Hash Unit PCB (bare boards, components included)
• Heatsink
• TP-Link Router
• Fans
• Cables
• Screws

These parts are from a project which was not finished. Parts have been built by forum member strombom. Everything is located in and shipped from Germany.

Auction rules: The auction ends at 6th Dec. 2013 23:59:59 UTC. A bid placed in the last two hours before the auction ends will extend the deadline by two hours from the time the bid was placed. The winner of the auction must pay within 24 hours.

Starting bid is 0.5 BTC per unit.

Can you provide information like links on how to build etc?

What you have to do:

1) Finish the hash units. We have the pcb, capacitor, resistors and all other electronical components necessary. You have the Avalon Chips.
1a) You solder it yourself, and place the components by hand and solder manually according to schematics (http://downloads.canaan-creative.com/hardware/A3256/avalon/2013-11-30/HASH_UNIT/)
1b) You engage a company to solder the hash units. We approached some (german and chinese) companies and have the necessary documents, if you want to go this way

2) All other components are finished already, so connect everything

3) Build the casings

4) Put stuff from 2) into 3)

5) Buy proper ATX and connect it

6) Mine!

7)

Profit

Now that's a proactive approach if anything, I'll say

Would this be a way of attaching the chips? http://www.youtube.com/watch?v=NdAibUZb1gQ

I don't have any experience with attaching chips, I would need someone to do it for me.

[ShadesOfMarble]

Yes, this is one way. You can also let a company do this if you send them the Altium files.

sounds like hard work. newbies will hate this but it will be useful for my training classes.

How many chips per board?

[sebdude420]

I'm in for one at .5 if you can also provide one completed unit too work off of. :-)

[sebdude420]

Make it 2 units at .5 I'm going too build these. What fun awaits!!

I've seen reballing done on chips, but not this.  He's putting flux on the board, and then just sticking chips on it?  WTF?!?  They'll just slide off, won't they?

See this video for a demonstration of reballing a game system CPU:

1 for me

We don't have a completed unit. If we had, we would mine with it and not give it away for a portion of its cost (0.5 btc). We prototyped 2 boards from sample chips, that's all. A complete unit has 32 boards.

How many chips per board?

A board holds 10 chips, as can be seen from pictures.

Soldering manually is hard work, yes. Having it done by a pick and place machine is not. But I guess you won't find a company doing it for 32 boards (1 unit) for a small price. We found a german company doing it for ~5000€ for all 500 boards, as well as a chinese company doing it for less than 1000 but their quality is crap.

Do you have solder stencils for these boards? 

[BitcoinBrains]

What kinds of chips does this run on?

Whats the hash rate of a completed unit?

[electronrancher]

Hey, here's one I can answer

The chip is 1st gen Avalon (A3256), and the expected hashrate of a full unit is 85-110GH.

What kinds of chips does this run on?

Whats the hash rate of a completed unit?

So it looks like this auction is ended..?  Can you please tally the buyers here and PM the payment address.

Sorry, no. Different companies use different stencils so you should let them make the stencil they require.
