Modular 5-chip gridseed miner enclosure

Thank you for the opportunity and I look forward to working with you in the future!

is the most aesthetically pleasing and also satisfied my functional requirements and is clearly the runner up. However, I have to give this to for the combination of versatility, easy of printing, easy of construction, compactness, and expandability.

I have marked with 5 stars all of those designs that met my criteria. If you are interested in my "bounty" and have a 5 star design please make sure you send me your public bitcoin and litecoin address.

Thank you everyone for the great designs. This is my first time posting a competition, and I will definitely do it again!!!!

Have you seen my conceptual design? Indicate if your concerns had been satisfied. I assume that PIA in your comment is warranty or something similar. Apparently the guy in cryptomining was not overly concerned with it, and mine is much more conservative approach since I propose liquid cooling.
I may turn my preliminary design into production drawings if you are interested

Manuel Rosso - It is a really interesting idea, but removing the fans on 20-40 of these by itself is a PIA, and even then you would have to find a way to mount the devices sans the fans inside the "fish bowl". I think it would not end up saving enough space to be worth the added cost of the fishbowl (which would have to rather large anyway) and would not be very expandable... I am totally open if you could find a way to do it in a modular way, but I see a lot of obstacles.

- I would like to see the power supply on top of or underneath the main farm. It takes a lot of shelf space with the supply in a channel between the two farms, although I still like the overall solution a lot.

More on that:

I see a solution where the devices are submerged in non conductive liquid.
There are some examples around of a whole PC submerged in this kind of liquids for heat dissipation.
Using this solution you may get rid of those noisy fans while having as much ASIC boards as you want in a "fish bowl" made of crystal plastic.
If you are interested I may do a design with this concept.

Unfortunately, the fact that the projects are not private compromises the originality, however, try to arrange the three key points required in the above

There are a lot of things I really like about this design. It allows for nearly infinite expansion, module by module; there are a minimum number of parts to print; it is compact and easy to build; and I think it could be stacked pretty easily. A few things to address when you finalize the design: (1) as currently designed, the fans are blowing in (towards the heatsinks) opposite each other - this will create turbulence that will impede the efficiency of cooling (fans facing each other are fighting against each other, and blowing hot air onto each other); perhaps staggering the fans in some way would solve? (2) while not a requirement, it would be great to find a way to expand in a way that is not just linear (stacking is probably easiest, but I am not sure more than 3-4 high could be stacked and still remain stable). In the final design, remember that there should be one power supply and 2 busses for every 20 units (or, another way to do it would be one power supply and 4 smaller busses for every 20 units). If these issues are addressed well, this would be my favorite design.

Also, for clarity, the added "bounty" above is NOT intended as payment for your design. ONLY the winning design will be considered paid for under the terms of the designer agreements with CadCrowd. In other words, I will still only have rights to the single "winning" design.

ADDITIONAL BOUNTY: Since this is a Bitcoin mining design solution, and because I think it has a fairly high difficulty level, I have decided to offer a very modest additional bounty of bitcoins and litecoins to the first 15 unique solutions that meet my requirements, subject to the rules below in this post. This is in ADDITION to the award that is already funded as part of this project. The bounty is pretty modest and it is intended to be more for fun than profit as the work required to create a successful design will probably be worth more than the bounty and winning $$ award combined .. it is just my recognition of the hard work you guys do plus it is in keeping with the goal of the project. It is also intended to get folks interested in bitcoins and alt-coins in general.

Bounty for each unique solution, subject to rules below:
0.025 Bitcoins
1.00 Litecoins

I may in my discretion make larger awards especially for a notable and superlative design that does not otherwise win the cash award (e.g., a notable and superlative second place).

RULES:
You must send me your public bitcoin and litecoin address (a "receive" address) to be able to get the bounties. You can send this by PM if you prefer or post in a comment (note that the architecture of bitcoins and alt-coins in general is such that the public address cannot be used in any way to undermine security since your private wallet keys are the only thing important to keep private - don&;t send me that!!).

A "unique" design is one that is not similar to any other previously posted design. A design variation (horizontal versus vertical, rotations, aesthetic changes, etc.) does **not** make a unique design, although such variations are always greatly appreciated.

A single person may receive no more than 3 such bounties (assuming 3 unique designs). Again, I appreciate each and every design but this is not intended as payment, more as a fun add on and I don&;t want one person to take up all the bounties.

I reserve the right to end the bounty if there are more than 15 unique solutions that are paid bounties. I may continue to pay the bounty after that, but it will be solely in my discretion. FWIW, I am trying to protect against someone submitting many designs that would require payouts far in excess of what I had planned. I will be fair about this, and if I cut off the bounty after 15 I will let everyone know here, and I will still consider paying bounties for someone who had work in progress.

I will be the sole judge of whether an entry meets my requirements, and my decision in that regard will be final. This extra bounty is not enough to argue about so please don&;t!

The bus bars I am using (2 one for positive, one for ground) are: http://www.amazon.com/Blue-Sea-Systems-Common-Busbar/dp/B0091VHLW4/ref=pd_sim_sg_2?ie=UTF8&refRID=15SW391KBD6DX0SBAM4F

There must be some place for these 2 power busses in the design (placed near enough to each other that a single power wire from a miner can easily be split and hooked up to both busses).

I am okay with an alternative bus for power if your optimal design requires different size/shape. If you choose to incorporate a different bus, please specify the model and make of the bus, and make sure it is rated to handle at least 50 amps continuous (at 13.8 volts), which is the approximate amperage of 20 miners at full load.

NOTE ALSO THE FOLLOWING ALTERNATIVE TO REQUIREMENTS: 2 or more structures may be used that **collectively** would support up to 20 miners ... and in that case you could use a design with one power supply and one common set of busses shared amongst the structures. For example, 2 structures each containing 10 modules, that are joined together with central power supply box and power bus that is incorporated as part of the design. This just occurred to me and it is an acceptable (and possibly better) alternative to a single structure that can be expanded to 20 miners. Ideally, such a multiple structure solution could be further expanded with an additional power supply (and one to two identical structures added on) to 30 or 40 modules. A full blown mining operation will involve 100 or more of these miners, so the concept of easily adding on to the "farm" would be nice (but not required to be so expandable, just a plus).

Also, note that I am using a single power supply with two external busses (positive and ground) to distribute power. In the lightning asic pictures there are two smaller power supplies with built in busses... I decided against that solution so please don&;t use the lightning asic power solution in your designs...

To get an idea of the wiring involved, look at the first post from the seller (he has several images but look for the one with all the miners on a table):https://bitcointalk.org/index.php?topic=421921.0;topicseen

each miner has a standard mini usb cable connection which will go to a hub (I did not ask for incorporation of the hub because there are too many shapes and sizes of hubs and I have not yet chosen a single hub ... so assume the mini usb cables need to run to an external hub located near the base of the structure ... or better design a platform for a generic but large 10 port hub and make sure either way that there is room to route the usb cables to it.

Each miner also requires a power cable, which is really 2 wires (positive/red and ground/black). All of the power wires must run to the high amp busses each about 6" long and 1" wide. The power wires connect to the bus with screw type terminals.

is really well - thought out and a great entry! My only comment is that there is not enough room for wiring and the power busses. Maybe rotate the power supply to horizontal and widen the design... which would leave room above the power supply?

Each miner consumes 60 watts at maximum power (600 watts for 10)

ok sorry i found info about Lightning asic

I wanted to ask if possible know the power dissipated heat sink, or at the most by any microprocessor, and the manufacturer of the fan. Thank you
