I think you miss a LOT space with this design. If you would use a rack adapter you would build in way more miners. At the moment you maybe use 200mm, but colocation racks have space for 750mm depth. Much unused space.
The other thing is... why do you use 3U for PSU? ATX-PSU's are designed especially for 2HU Height. So one would pay for 1HU extra.

Yes we are aware of that

To build a solid PSU Panel for 2HE it would have been double-angled wich almost means double-priced and the Rasberry PI would not fit in between the PSUs.

The question is, what does the customer wants. These panels can be produced for a low price, they can be mounted into racks or even in shelves.


We also had the idea for a complete Case with 26 Boards and one PSU in 3HE but building a whole case is sadly to expensive. ~300€ per pice + ~600€ developement cost.
If we somebody order 1000 of them they would only cost <80€ each.

yes that is one way to do it to mount it from the front and from the back. We want these panels to be as modular as possible.

There is no place inside for the plugs @3HE.
You could either go for 4HE and mount the plugs where the Anfi-tec engraving is at the moment or go for bigger watercoolers so you would have the plugs between the power connectors. To connect one row of Boards is realy easy because you have enough space around the fittings

If you have another idea where to put the fittings please draw or explain it. We are always open for suggestions.

To go from the back to the front we could make some additional holes in the PSU panel

We are not going for big datacentres with these panels
 
The redundant PSU is realy sweet  - But the price for the 2000w redundant PSU is 8 times as expensive (1600€ for 1700w) as a good PC PSU(100€ for 900w).

Keep in mind that nothing realy happends when the psu fails. Just connect a spare one and you are back in business. (sadly with some lost time).
I guess it would be better to have more miners than 30% less with redundant PSUs.

Hello I fast browse your thread, but don't find any info how pic (32MX795F512 in demo board. Same chip in production version?) firmware updates are handled?
 If your firmware have bugs/improvements how installed boards are updated? Can it done through CAN bus chained board?

Have you released pic sources yet?

PIC 32MX7xx have ethernet. Have future boards ethernet socket? (maybe somebody develop standalone firmware to avoid raspi..?)

When you plan release BOM? BOM and PIC firmware(/source) are needed bare PCB order customers..

Ethernet mac chip for pic32mx7xx cost ~0.99$ (in reel), rj45 socket less 0.5$, some xtal, res, caps etc and ~2cm² PCB area. Say total max 4$. RJ45 socket can leave unpopulated so customer can solder it if need. Other parts pnp machine lay board <0.1s.

One board can act master and chain other 16.
I see raspi ~50$ vs. ~4$ (plus onetime code/firmware generation = port cgminer to mips and some micro tcp stack).

If burning boards are done say 2000pcs and every 16 needs raspi -> 125 x 45$=5600$. I can't say is it enough to modify board now. Atleast it reduce one board + wires when suitable firmware are done.

I see it good option, not reinvent wheel.

A raspberry pi is $25. and its a fully fledged computer running on archlinux, you connect your chain of Bitburners to the USB port, and cgminer on the PI does the work for you.
Where would cgminer be running in your option?
I definetly see it as an option, just not a necessary one for me at all. Especially, when he starts shipping, the difficulty will be way up, and second generation chips would already be taking orders.
Keep it simple!

Driksson:
Raspberry pi is 25$ only for A model without ethernet. 45$ is with delivery.
Delivery will be split between 125 raspies but still.
If you are answering message-read it first(about cgminer porting to one master plate with ethernet)

Eros:
If you want to 11 000 Gh then use BitFury device, electricity company will thank you.
Also i am sure that if you will order 40000 avalon chips and pay to burnin $200000 plus delivery then you will get on your plate everything you want.

Looks like a good, simple solution.  I only have 4 boards myself so I'm def. after something like this as well.

Im do some planning on how to arrange my cooling and i need some further details.

Could you tell me the exact dimensions of the Product itself and the size of the aluminium heatsink ?

Aslo: Which connector can i use to connect each board ? How long can this connector be ?
I would probably need a cable length of 20 - 40 cm depending on how the boards are stored.


btw: are there any news burnin about the watercooled device bitburner : ) ?
Please tell us its fucking unbelievable awesome and can be extremely overclocked : }!

Are you going to use DHL Express within germany the same day the unit gets assembled? maybe overnight express? Otherwise I'm tempted to take a trip of 1300km..
