Hope you dont want to remove the battery....

kimmo: great news! Are you planning on experiment with that next? Having an UART interface on a mobile phone would give new ways to interact with various devices.

Re: Jolla OtherHalf OLED display
 
I know this OLED display is soon getting crowded :D (as there is already a proximity sensor on the list), but I was wondering about adding a button in some form.
Use case: you have the phone laying on the table screen down/OLED up, you read e.g. the current time, and without lifting the phone you can access some other information on the OLED screen by pushing some button.
Maybe use *two* proximity sensors? If both return 'near' -> turn off OLED, if you cover only one of them you can change info on screen.

I was thinking this too... i was thinking "flashlight button".

Problem here is that button needs somesort gpio expander to get it on the bus.
i think the proximity sensors can be used to detect some easy gestures :) wave hand over, and it shows something else for 2 sec.

(I noticed that after i changed the oled to white one, it looks now like my N9 and i'm tapping on the backside to wake it up...)

There's also the possibility of using an OLED screen with capacitive digitizer, if such a beast exists :D

Re: Jolla OtherHalf OLED display
 
Btw, how feasible is this thingie?

Re: Jolla OtherHalf OLED display
 
If there's nothing extra special on the other side of the board then it seems it needs just a handful of discretes, nothing too fancy to build. Could be doable. I guess the shown components then are enough to generate the voltages needed by the display unit.
(I vaguely remember reading somebody state that e-ink dispalys need also negative voltages to operate...)

update:

SW Got connected with ofono to get signal about new SMS...

Code:
    static const QString service = "org.ofono";
    static const QString path = "/ril_0";
    static const QString interface = "org.ofono.MessageManager";
    static const QString name = "IncomingMessage";

    static QDBusConnection conn = QDBusConnection::systemBus();
    conn.connect(service, path, interface, name, &toholed, SLOT(handleSMS(const QDBusMessage&)));
HW First PCB version ordered. Flex had 6 week deliverytime due coming chinese newyear, so had to go with 0.4mm (hope to get them by end of month)

Update: SW

Managed to get interrupt (poll) from front proximity detector, and just for testing - oled display is off when there is no proximity... (and on when there is)

Power consumption... you asked, i answer.

Phone used as by my daily routines, mixed WIFI, 3G, playing heebo while taking poo, email reading, etc.

After ~14 hours of use, the battery capacity difference was 2% (Error margin might be larger than that)

OLED_OFF was monitored at random intervals and OLED_ON was logged by the daemon itself.

Re: Jolla OtherHalf OLED display (Waiting for PCB)
 
Finally i have some information about the "take my money" section too...

The cost for making just few (<5) of pieces of toholed is roughly 40€/each including 'professionally' made 3D case from sculpteo (e.g. polished black plastic (or pink)) which is about half the price.

(Based on prices i have paid for parts inc shipping)

Re: Jolla OtherHalf OLED display (Waiting for PCB)
 
Unless you finish the eInk OH project (that I prefer) just a few weeks after this one, then you can count me as a preorderer already if the screen shows more than just clock (which I think it does)! :D

By the way, will the screen surface be at the same level as the OH surface in the final model? I mean, compared to the picture below, where the screen is "inwards" instead of actually framed by the OH plastics:

Count me for one. :)
Do you want me to post some pictures of the polished black plastic from Sculpteo? Feels like paper on touch but it is rather sturdy. I wonder how multicolor will be (it is a bit cheaper too).

Just let me know how to send you the money, paypal ?

Great work, love this :)

Final will look 'the same', but the display will be only about 0.5mm down from the surface. (which is minimum wall thicknes at sculpteo) The display glass is larger than the visible area (where the pixels are), so it looks better even it has small bezel.

Seems you already have your 5 preorderers then! Perhaps even 6 if DJJonosound wants one, not sure from his post. :]

You should engrave serial numbers on them, I'd have the #1 and would spread my pride everywhere. http://forum-images.hardware.fr/imag...petoulachi.gif

What's the size of the screen? 0.96 or 1.3 inches ?

it is 0.96"

What Juiceme said.

Latest print finished...

Total phone thickness now 11.5 mm (original by spec 9.9mm)

https://lh3.googleusercontent.com/-B...o/14010025.jpg

bezel is now three layers (0.3mm) thick:

Really thin 2-sided tape used to fix pcb to printed part. oled might need to be glued in place:

Re: [WIP] Jolla OtherHalf OLED display
 
Great work. Really impressive stuff!

It looks very nice already but you mentioned wanting to use a flex PCB. Would that shave some tenths off the thickness or this basically the end product?

Flex had ~6 weeks delivery time due chinese new year, so i did make order for this 0.4mm (actually closer to 0.5mm) board.

Flex should be around 0.2mm so no big shaving... At least first batch will be done with these.

When ordering these from Sculpteo, they have minimum thickness of 0.5mm... this shouldn't affect total thickness, but the display will be at this depth...


Unfortunately i yesterday realized that i have Eagle Hobbyist license, and i need to invest to standard version before i'm allowed to sell these boards... otherwise i'm being prosecuted..
