Hey guys,

Now to the bad News guys:

As you know in designing the Case I considered primarily the old mboard, the only change I made is hole alignment on bottom to fit both mboards.
The big Problem is that the Raspi looks in the wrong direction when mounted directly on the new mboard to the Fans.

Current projects if you are interested is an Shash board Case.

Try making the flat cable much shorter. It might be too long,
just picking up noise.

And do you have a seprate thread on the S-HASH casing?
Highly interested:)

As far as V1 M Board the default cable would normally work. However the problem is the orientation of the connections. One end of the cable will have pin 1 row connect to pin 2 row and pin 2 row will connect to pin 1 row. Thats not good

You have to modify one end of the cable to make pin 1 /row attach correctly.

unfortunately I killed two raspberry pi with the original cable! don't use it!

I have 1 of foofighter's cases, still unopened in its box as I received it (I realized I wont need it after all). I am willing to sell it for 2.5BTC including shipping with tracking. Please PM me if you are interested.

If you prefer escrow, I have it on sale slightly at a higher price, at bitmit for (2.5BTC auction start) 3BTC(buy now) + 0.2BTC shipping.

I tried it again with theses adapters http://piborg.org/triborg.

But still no luck Sad

(again connected it directly after testing).

There is no problem with the cable itself, but somehow the connection of the cable doesnt work Sad

Havent found out why, maybe someone who got his already has a solution?

I got the case you sent but did not even open the box yet since I have nothing to put inside

... It would be nice to know if somebody could get their cable work or not...

All Units shipped.

Thanks for the awesome work. I was wondering, is there a problem with the shipped cables or not?

All Units shipped.

tested the cable with ohm meter -should be fine but didnt see it in network manager.

Yesterday I saw it in network but couldnt connect which was a sign that the interference on the cable was too big maybe.

After shorting cable, no sign of it in network manager Sad

Raspi works fine,

yeah maybe 1 or more pins are too short and have no connection or something.

cable reworked but no luck so far, also wrapped some alu foil around it, doesnt help.

Have you tried it on a new raspberry pi? Not sure if that first Raspberry pi suffered damage due to having power feed on wrong pins originaly.

Consider trying that first if you can.

Edit: Also use an ohm meter to check the continuity of a cables 1 to 1, 2 to 2, and so on.

Try making it much shorter, SPI communication over unshielded cables is probably the problem.

sounds like EMI interference along the lines. This may be a good reference/example of the issue: http://www.overclock.net/t/1424387/gallery-build-log-ultimate-wall-mount-rig-maxxplanck-v2-completed

Guy build a dead-sexy wall-mounted coputer system and used pci extension cables. basic cables caused his GPUs to not turn on. aluminum foil-shielded cables enabled the cards to run, but disconnect under 3D applications. He resorted to professional shielded cables for a working result

try wrapping it in aluminum, or using a shorter cable. Your image shows that it folds over itself a bit because it is ~4inches too long, and this could be enough to cause interference

Hey guys,

The last days/week I really worked every spare hour sometime till in the morning, because of reworking the cases and stuff.

Iam happy to tell you that all cases will be shipped on Monday, you will get the tracking number via PN on same day.

Now to the bad News guys:

As you know in designing the Case I considered primarily the old mboard, the only change I made is hole alignment on bottom to fit both mboards.
The big Problem is that the Raspi looks in the wrong direction when mounted directly on the new mboard to the Fans.

For this I made also Raspi mounting holes on the bottom and got some GPIO cable with adapters to connect to the mboard without problems, but somehow the Miner doesnt run with the GPIO cables.
see here how it was supposed to work:

It is still possible to attach the Raspi directly onto the board but this front plate will be bend to the outside slithly.
see in my setup here.

Sorry for the inconviniece guys, I tried everything -maybe my gpio cable is broken and the ones I packed for you are ok.

I hope this is alright for you guys.

Current projects if you are interested is an Shash board Case.

Hi guys,

I will take the time to tell you about the problems.

First I thought I could usw sheet metal screws to fix most of the stuff, but this aint working because of painting thickness and other issues.
Now I have to cut a thread manually in every hole in case and mounting brackets to fix this.

The next thing was the Raspi mounting. as the Mboard was changed shortly before I ordered i had not really time to adapt everything. If the Raspi will be mounted directly on the new mboard , the RJ45 connector will push on the edge of the 3rd fan but it will just work fine.

As I was not satisfied with this, I reactivated the bottom mounting holes of the case and now mounted the Raspi on the bottom connected to mboard via gpia with adapter Pins.

Here are pics of first full assembled case, ready for shipping:

EDIT:
Only 1 case left to sell!

Hi guys,

sorry for the few news lately, work is in progress - see pic.

But there are some issues which I have to solve first and rework some stuff by hand.

Will come back to you with a more detailed updated when I have a bit more time.

It looks like punin is not shipping a cable to extend the raspberry pi to a different location. Will it still be possible to use your case?

Hi,

thanks for the info.

I forgot to mention that, but I changed things a bit so a direct mounting of the Rasperry to mboard is possible.

I will test every case before shipping, so everything will fit fine!
