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

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

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.

Raspi works fine,

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

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

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

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

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.

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.

regards
Foofighter

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:)

intron


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 Smiley

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!
