Spacerframe - Impressions of Neo900
On the way to the inevitable "spacerframe" for our neo900, I sketched some impressions of how the neo900 might look. I also sketched a cross section of neo900 vs n900 to show why a spacerframe is needed.

Edit: Note: The actuall added height will be 2.8mm. Especially in the sketch it looks alot thicker for explaining purposes. I'd like to stress these are only sketches/impressions. Nothing is to scale and my drawing skills might not be appropiate ;-) |

Based solely off the rough sketch, I see that the phone might be pretty thick.
How thick is the spacer gonna be? |

That's actually not bad at all. The spacer's much smaller than depicted from the rough sketch. |

The spacerframe will increase thickness by ~14%, from 19mm to 21.8mm The sketches are anyway great to explain what is this spacerframe thing. Thanks a lot for posting them here, jake42! Nice and useful work :) Let me add another link to some less beautiful drawing I did: http://neo900.org/stuff/joerg/spacerframe/sketch.pdf. and here are very fine scans Werner did: http://neo900.org/stuff/werner/scans/ /j |

Not what I was expecting!

Re: Spacerframe - Impressions of Neo900
Next time we wll succeed to ask our crystal ball to meet your expectations. Sorry we failed this time

Re: Spacerframe - Impressions of Neo900
Specerframe is not bad. It should be get to good use. Can there be somekind of hole for attachment for this: https://developer.sony.com/devices/c...mera-dsc-qx10/
:) Or port for developerport serial. Or just pocket for microSD-cards. Or pocket for little notepaper. Or ... |

But again, connected slots would be best, and I am aware that both ideas are probably not feasible anymore now. |
Re: Spacerframe - Impressions of Neo900
Guys, guys, hold your horses, please. Don't you think that if there were room in the spacer for all those things, there would be no need for the spacer in the first place? Or was that the point? Am I being obtuse?

Re: Spacerframe - Impressions of Neo900
Neo900 won't have an "external" uSD slot, you need to remove the battery lid to access it. Neither any unused free volume inside device nor an unused SD interface exist in Neo900 design.
So here's my suggestion:http://maemo.cloud-7.de/share-service/20160621_002.jpg [edit] for the mentioned Sony camera: it says it comes with phone attachment |

Sorry for the misunderstanding. I jumped in after the post I quoted in my previous message. :o [Edit] Joerg_rw, don't know if that will be possible on the Neo900, but on my N900 I can manage to store an extra µSD on top of the currently used µSD, just by shifting it a little so the bump does not stack. No noticeable extra pressure on the back cover. |
Re: Spacerframe - Impressions of Neo900
No, I am sorry. I may have gotten it wrong. Can you clarify, joerg_rw?

Re: Spacerframe - Impressions of Neo900
I think you were perfectly right :-) despite the "original rationale for needing the spacerframe" is also correct, it been intorduced by modem module height, but meanwhile we crammed in so much that we used up pretty much all of the additional space

Re: Spacerframe - Impressions of Neo900
Can the DIY hacking port be used for these external SD cards and other ideas? How many GPIOs and UARTs are in that?

http://neo900.org/stuff/papers/hb.pdf There are enough GPIOs for 1 bit operation, or if you use some of the UART signals as GPIOs, then there are enough signals for regular 4 bit operation. The regulated supply voltage available on Hackerbus will probably be 2.7 V, which is just at the lower end of the standard SD card voltage range. Finding a nice place for the card holder would be more of a challenge. I guess there should be sufficient room if you remove the camera. Else, some creativity may be needed :-) When looking for such a place, the scans and photos here may help: https://neo900.org/stuff/werner/scans/ - Werner |
