Possibly with a *very* thin metallic shield (e.g. mu-metal) to block the magnetic field on the bottom.

And that includes also shielding Jolla GSM+Wifi+BT antennas? Hmm...

Personally I vote for 1mm thinner!

Although, I'm not sure if having bare magnets on the backside will attract random metal objects nearby. Every once in a while you'd have to brush staple pins and paperclips off your pocket :)

Possibly a stupid idea:

Use some crazy glue to hold the magnet in place. This way the magnet is closer to the other-other half and the wood covers the whole back side (thus distancing magnets from attracting paperclips).

Hey dirk,

could you explain, why this is not working.
I have read all post, but i don't unterstand.

why do the magnets have to be on the bottom if they should attach to the magnets of the Jolla backside (the upside of the keyboard, right?)?!?

Hmhmh. I played around with Sketchup, but I suppose I'm fine with the rounded cutouts in the wood for the two magnets. I do really like the third one, as the wood is slightly less overwhelming (exhibit A, B), but it'd obviously be significantly harder to do so not feasible.

Then again, the grey wood ("kelo") is more subtle, both on white and black keyboard pieces.

Oh why not? After seeing the sketches I like it even more. How about a poll?

From what I understand from following this thread, he made extensive and thorough R&D to come up with the project as it is.



Imho, making substantial changes at this stage is not such a good idea.

Changing the position of the magnets may appear simple but, e.g., adding new components (like glue, epoxy, ...) and the combinations of the components (cover <-> glue <-> magnet) imho add significant error potential and would require to repeat quite a lot of R&D or even longer additional testing.

Similarly, injection molding may sound cool. But there are many uncertainties as well, e.g., the molding process may vary, the molding tools may not fit on the first try, or the quality of the material may not match the expectations.
Furthermore, the costs for iterations in molding, e.g., when the tools have to be changed are in the magnitude of thousands of euros compared to about tenth of euros for 3D-printed parts. Plus the advantage dirk mentioned that the 3D-printed parts can be re-ordered by anyone who has access to the respective files.

Last but not least, the backers at kickstarter had a very good overview to know what they subscribe to. Changing this afterwards could be problematic and may lead to frustration and disagreement.
