Re: Neo900 - finally a successor of N900
 

I ain't watched the video, but I've had a look at the photos - very good work everyone! One month from start of idea to a prototype board, I've not seen even a big company turn out a device so fast in my life! Makes me glad my heart and soul is behind the OSHW community.

I cannot wait for this board to upgrade my N900s. Of course I must, but there is uncontainable excitement there, this is really looking the goods guys!

Once again, well done, and I can't wait to see what is in store for us all!

Shane.

This has been going a lot longer than one mth all up, but impressive progress, still far from fully polished though, I'll be buying a least one board if I can spare the $.

Re: Neo900 - finally a successor of N900
 

Hi
I'm wanting to acquire just the internals for the neo 900 for maybe 1 or 2 n900's
If i make a 200euro's donation will that go towards the purchase of 1 or 2 neo 900's?
Do in need to split the payment in order to secure 2 neo900's? Depending on how they turn out i may only want one. .
And is the paypal link working yet?

Re: Neo900 - finally a successor of N900
 

There is no paypal link
cheers

Hi
I clicked on the link in your answer and this is where it brought me.

Re: Neo900 - finally a successor of N900
 

Around two months overall, together with idea conception, checking the interest etc., but one month after fundraiser started (and also around one month aftrr the fundraiser reached phase I :)). So technically mechanical evaluation work started when we got 5000 EUR and now we presented first results to the public (and to TMO even earlier :D)

Re: Neo900 - finally a successor of N900
 

So, if I understand correctly from the video, there are two circuit boards, one with the CPU and one with the modem? How do they connect? Would the modem board be swappable (e.g. could I have one modem board for the U.S. and one for Europe, and put the necessary one in)?

Re: Neo900 - finally a successor of N900
 

I've got from 22/8 till now (well, till a few days ago) anyway, still good progress, long way to go ofc.

Re: Neo900 - finally a successor of N900
 

Three then. How time flies :) I could swear it was only two months! :D But with fundraiser duration I'm still right, just rechecked! ;)

Re: Neo900 - finally a successor of N900
 

It really depends on what you consider the cut-off point to be, really there shouldn't be any cut-off point, yet.

Re: Neo900 - finally a successor of N900
 

Phase 4 completed!

We're already at 200 devices, woohoo! Thanks to S. M. who made 200th donation with >= 100 EUR :)

So...

Phase 5 starts!

Can we reach 1000? :D

And there's no "cut-off point" yet, the only one was rather psychological one set by Joerg to reach 25k EUR and 200 devices till the end of the year. Both are accomplished, so everyone willing to jump in (so maybe we reach that 1000, making 1GB RAM almost a no-brainer!) will be able to do that until we're deep into sourcing and ordering the production :)

Re: Neo900 - finally a successor of N900
 

I am hoping to pre-order one as soon as my funds open up a bit. I really want this project to succeed!

Re: Neo900 - finally a successor of N900
 

Now this gives hope that I can to jump the ship!

Re: Neo900 - finally a successor of N900
 

If you're going to achieve this you need as much publicity as possible. I just submitted a story to Slashdot. Let's get this modded up!

Re: Neo900 - finally a successor of N900
 

Huge thanks! Seems to be gaining popularity, already orange and high on http://slashdot.org/popular

Everyone please help if you haven't yet! :)

Woohoo we're there! http://mobile.slashdot.org/story/13/...for-production :)

Re: Neo900 - finally a successor of N900
 

So what audio chip has been picked for the Neo900? Same tlv320aic34 as N900?

Re: Neo900 - finally a successor of N900
 

Yes :-)

Re: Neo900 - finally a successor of N900
 

Hey guys,

I have problems charging my N900 off a 12VDC to 5VDC USB adapter. Its supplying 1A, but I have a 500mA plug, and it too doesn't want to charge the N900.

Charging my N900 off a 12VDC source, such as a car battery, is crucial to me, and it looks like the N900 doesn't want to play ball. My Macbook will charge it, but at something like 350mA, which is pitiful, especially if the N900 is in PC Suite mode supplying internet over the USB - I'm using more power than I'm supplying.

What provisions have been made in the Neo900 to make sure it'll charge off any 5VDC source you throw at it, regardless of origin (so, power brick, laptop/ PC, or cigarette lighter plug), because I really don't want to be saddled with a phone that rejects half the power sources I have in the house for some odd reason. I am getting an extended 18Ah LiPo extended battery pack for the Macbook, but I am also getting a VAIO Duo 11 with extended "sheet" battery, and it has a nice over powered (so 1A) USB3.0 charger port (as well as supplying USB data). I will probably use the VAIO for six hour train trips from now on, when I get the bloody thing, and leave the Macbook at home. Don't worry folks, I'm running latest Ubuntu on it, I really can't stand Windows =P

Thanks for the help guys!

Shane.

Re: Neo900 - finally a successor of N900
 

Never seen that problem... I have used that (that particular) phone on a car charger, but it was just a standard car adapter from the service station.

Re: Neo900 - finally a successor of N900
 

1. What does this have to do with Neo900? Please learn to observe the thread's topic. Posting your questions in random threads is generally frown upon.

2. Check your car charger's USB connector. I have three car chargers. All of them work but the connection is rather temperamental. So far I had the best results with the cheapest one from Poundland. which has a USB A female connector instead of a cable sticking out, coupled with a cable that I know works on a PC.

Re: Neo900 - finally a successor of N900
 

For Neo900 we will provide battery charging pads under the back cover (when we can find a way to do so), and we will take care to make them as tolerant to crappy supply as reasonably possible.
For USB we need to follow the common USB2.0 & charging_amendment specs, and we will probably use the same detection scheme like N900 (D+/- short), since it's the simplest (for user to handle) of the 3 variants for fastcharger detection that the USB specs define (the other two involve resistors to get soldered to the plug, sth you don't want to do). Anyway we will take care that charging is controllable by software just like it is on N900.
Please check other threads in this forum about fastcharger detection and D+/-_short

Re: Neo900 - finally a successor of N900
 

Why is that?
Is there some adhesive that's hard to replace or is the dome sheet easily damaged in the process? Or is there some other problem?

Here at 1:52 [1] it looks not trivial but quite doable to remove the dome sheet. However the next slide in the video says: "Do not use the domesheet again."
I'd like to understand the reason.

Of course reassembly might be a completely different story than disassembly which is why I usually don't like disassembly guides that end by simply stating: "to reassemble just follow these steps in reverse order."

@sulu
Errr, YES. ;)
All you said.

Re: Neo900 - finally a successor of N900
 

Throwing in my tuppence for what it's worth, my N900 gives me the most grief when dealing with modern chargers designed for the resistor-style phones everyone has now. Basically, it just doesn't charge unless I use a really dumb charger, even when I cut the data lines completely. If the Neo900 could be a little more..."robust" it would be much appreciated! I suspect the problem is with the "play dead" state of the phone, as most decent chargers alter their state based upon what's plugged in...and so does the N900, so they cancel each other out once the N900 boots past the hardware charging state. Every other device I have works with my chargers just fine...

...but yeah, if the Neo900 could be more robust, that'd be great :D

Re: Neo900 - finally a successor of N900
 

I'm pretty sure you already know this, gerry-mobilfunk.de seems to have domesheets. [1]
I have no idea what happens if you input a 3- or 4-digit number into the quantity field. I'd like to see Gerry's/Thomas' face though. ;)

Maybe he knows some secret supplier. At least asking him wouldn't hurt.

Re: Neo900 - finally a successor of N900
 

This audio chip appears to be able to record 24bit data
off of four inputs if I read the spec sheet right.

Maybe I need more coffee,
but maybe someone out there knows if it can ?

If so - I would assume (don't get distracted here)
we would have a normal stereo/mic jack for line input
and have an embedded mic (1 or 2 ?)
for the audio input ?

just curious,
it gives me some ideas for later on down the road....

Re: Neo900 - finally a successor of N900
 

Yes, I already know Gerry-mobilfunk ;)

Re: Neo900 - finally a successor of N900
 

That's the plan. I don't know off top of my head if the codec can do 24bit.

Re: Neo900 - finally a successor of N900
 

Perhaps this is a little more on topic for the discussion - do we have any idea of power consumption while providing internet over hotspot (so 4G and wifi interfaces active) in terms of what I would need to provide to the phone in order to keep it charged? I'm not asking for real, hard figures yet, I'm just looking for a consensus in terms of whats expected.

In relation to the previous "off topic" post (my apologies, I've owned an N900 for about a month - the idiosyncrasies are still being worked out on my end, my PwnPhone firmwares wifi is botched, meaning I have to hardline the USB for internet, but thats ok, cause I've gotta keep it charged) the VAIO Duo I'll be getting has the 1A USB3.0 charge port, specifically for fast charging devices like mobile phones. If power consumption of the Neo900 while in hotspot mode could be expected near that 1A, I'll be mighty happy, that'll mean I can run my phone indefinitely off the laptops extended battery - perfect for six hours worth of train trips, which I do regularly, where the old Macbook Air's battery dies after two hours (go figure).

It is a fact that for almost two hours of those six on the train, I don't have cellular reception, but thats a minor side issue I'll sort out with the Government Railways one day... *GSM-R tsk tsk*

So, I hope this is a little more on topic - again my apologies, I wasn't aware my issue had been debated to death, although I should've expected a software patch for it...

Many thanks!

Re: Neo900 - finally a successor of N900
 

There is a thread for the N9 which they are discussing modified bluez for BLE the low power bluetooth protocol which can be used with gadgets which can run for months on a battery or charge. Hoping we can use their software work on Neo900 BLE bluetooth 4 hw. http://talk.maemo.org/showthread.php?t=85118&page=4

Re: Neo900 - finally a successor of N900
 

Maybe a USB mode switch like we use for host mode, normally USB compatible but you can switch it to tolerant of un-shorted power supply, perhaps even set the amp draw

Re: Neo900 - finally a successor of N900
 

I'd be really surprised when nobody built such thing yet, maybe based on charge21.sh

Re: Neo900 - finally a successor of N900
 

I had to remove (and replace back again) keyboard domesheet on few of my N900's for various reasons, and it went without problems. It just require some basic care* to not damage it during unsticking, and some focus to allign it back again when ready to stick (there are some "nav points" - holes etc - that make alligment easier), but it is perfeclty doable. Glue could get non-sticky if repeatedly removed and inserted few times in row, but for single re-attachement, it shouldn't pose major problems, especially for Neo900 "target" buyers type.

/Estel

*the same care as with unsticking any should-be-easy-to-remove sticker from RTV/AGD

Re: Neo900 - finally a successor of N900
 

domesheets must be sourced as if once removed it can be perfectly reused but some air leaks or less sticky regions will be there and in the long run poses problems in keypresses mostly due to a layer of something formed by oxydation or sometimes slight misplacements change the keypress feel diffrent for others :).

Re: Neo900 - finally a successor of N900
 

Maybe a stupid idea but here it is: I've seen some demos of water-repellent solutions that you dunk (spray with?) your electronics in and it makes them water-resistant.

Any chance?

Re: Neo900 - finally a successor of N900
 

So for keyboard you decided on domesheets?
What happened to the idea of having the buttons directly on the mobo?

Re: Neo900 - finally a successor of N900
 

Wouldn't that kill (or at least "damage") the illumination?
