Big Update From Ed

[haptagud]

But more on topic:

Awesome sweep of news these past recent weeks eh?
*In short, Micheal has shielded the LCD ribbon, and that test prototype is ready for final testing.
*The boards been having a pretty decent head start in production.
*The case samples are on the way.
*The CE actual test could be starting sooner than I thought

This could mean that allot of things could get done within about two weeks of each other, so the next biggest thing might just be assembly.

Yes on topic posting! Here's hoping the shielded LCD ribbon works as expected, though from my point of view it would be interesting to test a final MP-Pandora with and without the shielding. Since it's going to be a bitch of a job manually shielding 4000 LCD ribbons! But I'm feeling optimistic we may start to see some shipping of final units out to customers by Xmas or the new year...

I want to see some shipping by November... :unsure:

 

[Critical_Impact]

I think everyone is hoping for a November release. It would be friking awesome as I'm going on holidays on the 6th of December and having a Pandora on the plane would be way better then a DS and it's terrible battery life(well mine has terrible battery life, maybe it's just mine )

Wow these boards have just turned into a cesspit of hatred.

Wow these boards have just turned into a cesspit of hatred.

I guess there are some people who have gone a little crazy while waiting for the Pandora :lol:

 

[iprice]

If you think this is bad, just wait until people have it in their hands. Just wait until the complaints of faults/problems and general disappointment that will be revealed, since the Pandora can't possibly live upto the hype and hopes that people have for it. Once people can actually feel the keys and move the nubs, have trouble installing emulators etc. etc. that's when the real hate will come.

This is just the build up to the storm

Just make a newbie forum for them and stick em all in there.

And lies!

(They've turned from previously being "a miserable pile of secrets" into it...)

Seriously. Posting on these forums is like walking through a minefield while wearing a blindfold. You don't know when it's going to happen, but someone is going to blow up in your face.

Edit: I should add that I probably wouldn't take it personally in any case. I've grown to appreciate the crankiness and sardonic tone of this place.

No, this is what it should be:

You guys are far to modest, the first Pandora rolling out from the assembly line should clearly be accompanied by http://www.youtube.com/watch?v=1aKAH_t0aXA or http://www.youtube.com/watch?v=cWnmCu3U09w

 

[juniorm33]

I've been posting and starting threads like a crazy man, and not been flamed yet (knock on wood) so kinda expecting it soon, did even think I should stop posting before it happens. So if you don't see me for a while you know why!

[Edit] Wow has this gone off topic. Hopefully There'll be an update from them soon.....

They should have a rube goldberg machine making the Pandoras and have this song accompanying it http://www.youtube.com/watch?v=hettbehUb0Y

RE: Shielding

Am I wrong to assume that normally, when you are shielding something, the shielding is terminated (wired, connected, soldered, whatever) to GND (ground, minus, negative, earth, take your pick)?

In all the talk I've seen about the ribbon-cable shielding I haven't seen this mentioned. How is metal tape (tin foil, screening, shielding etc.) just surrounding the ribbon cable going to reduce emissions if such emissions are not routed somewhere harmless (/dev/null) after hitting the shielding material? Isn't a wire connecting the ribbon shield to GND (minus, negative....come on shoot me required?

Cheers,

P.S. don't nobody point ya finger at any speling mistooks I maik coz they're all intentional

It's a shield against EM fields, not against electrical current. The magnetic effects are dissipated as small currents in the shield, they don't have to "go" anywhere because they're not electrically coming from anywhere.
I don't know a lot about EM stuff, but I'm pretty sure grounding it wouldn't have any effect, since it's more of a magnetic shield (Try looking up Faraday cages, I think it's like a partial Faraday cage) than an electrical component.

 

[WoD]

Woohoo! The Pandora is imminent, and the Nokia N900 is due on the 9th Nov! Gadgets abound! Too bad the threat of redundancy looming over my head will likely put a hold on Core i7 iMac goodness.

I think the idea of the shielding is to keep the EM fields contained in the ribbon cable. The shielding works like a mirror, reflecting these fields back into the cable (rather than letting them spread free over the air). Essentially confining the EM energy in the cable, which will eventually make it to the circuitry (on LCD or on main PCB) which consumes it (when the signals are read). This reflective behavior is a property of the conductive materials, grounded or not.

Grounding is used more to shield the signals on the device from external interference. The problem is that external fields can induce currents/noise onto the shielding itself, and then onto the circuits inside. But by connecting the shielding itself to ground, the effect neutralizes itself.

Its not that the ground "absorbs" the noise (think about shielding on portable devices), but that the device's ground changes to match the noise. The electrical signals are also affected by the same noise. The electrical circuits naturally cancel out that noise, since they compare every signal to the ground reference (read substraction):
Signal - Ground

If both are affected by the same noise:
(Signal+Noise) - (Ground+Noise)
Signal + Noise - Ground - Noise
