Maybe i'll start with the Theme.fontHeading which is used showing the Clock in the lock screen...

Screenshot to bmp, then processed to a single table with dot factory Next some code to copy this to screen...

Great stuff!
I want one, that shows bootloader/dmesg logs :)

This is already a planned feature.
In the phone is already TSL2772(3) -chip, it is available from digikey for ~1.70€ / 1pc, supports 1.8V I2C levels. It is in different bus, so i can use same address for this...

Re: Jolla OtherHalf OLED display
 
so ****ing cool man. i assume this can be programmed to show battery levels as well? :) a low power oled device would save battery since users can view stuff without having to activate the main display.

Re: Jolla OtherHalf OLED display
 
I just got a phone call (which is irrelevant) - but i got idea...
it would be nice to catch the call from e.g. DBus and show callers id on the toholed too...

So if any DBus experts out there, could use some info, (e.g. Python script is ok) I'll code it with C++ to my daemon anyway.

Not an expert at all on this :), but perhaps some useful information here ? http://talk.maemo.org/showthread.php?p=713803

congrats for that awesome project :)

How did you find where are the I2C bus?

kimmoli 2014-01-09 20:11
Re: Jolla OtherHalf OLED display
 
What do you mean? Physical pins? They are located on the back side of the phone, and documented in this forum under few threads, e.g. here http://talk.maemo.org/showthread.php...ht=i2c&page=18

I have made tool for debugging the i2c bus, i'm just going to 'publish' it here.

Not sure if this is still relevant for Jolla:

These are the DBus things with "call" in the name:

Code:
"org.freedesktop.Telepathy.Client.voicecall"
"com.nokia.telephony.callhistory"
"org.nemomobile.voicecall"
"com.jolla.voicecall.ui"
Lets see which of the maps best to com.nokia.csd.Call

I have to check what components i need on the board. atm i expect about 2mm increase in thickness.
i don't know about price and availability but could flexible oled displays be a thinner (and more robust) alternative?

Don't know either.

atm the pcb thickness is reduced down to 150µm and there is opening for the display glass.
Current cover thickness is ~1.2mm so, with minimal thickness bezel say 0.4mm, the total thickness will increase 0.6mm.

None, it uses ofono.

You're doing great. How did you manage to make it that thin? The pcb i mean.

Finally had time to do some cad work for current prototype...
printing this night.

Thanks to skvark for 3D model 'template' (this is edited from the solartoh)

Wow. This is probably one of the coolest things ever done here at TMO. Keep up the awesome work...

This makes me waiting for one that much harder.

Super!
So, this is a sligthly thicker TOH cover that has space inside to allocate the screen, right?
On Friday received my 1.3" OLED and in a couple of days I should get three spools of PLA (including some blue glow-in-the-dark samples...) so I'll try it myself.

This is still about 2mm thicker than the final should be.
(But it is needed to fit the proto electronics, if i get rid of that current boost converter inductor, i can get it little thinner.)

Print was almost ok (biggest problem was that i didn't print the last version :mad: )
https://lh3.googleusercontent.com/-R...o/14010013.jpg


More pics:

Whole thing
Camera detail
Insideout
Translucent black

From the last pic you might notice a problem, this is what was fixed in the version that i ddn't print.. noh, it is only 2.5 hours to get me a new one.

How well did the model fit?

It seems that my printer makes about 0.5 mm error when comparing to the 3D model in length but otherwise it prints like modeled. Just curious if I should recablirate my printer/modify the model.

Did you have this kind of problem: https://github.com/skvark/TheOtherHa...omment-5043076

Quite well, little tight (but i like it that way).

Hmm, the PLA can have about 0.3 to 1% shrinkage, which my explain tightness in the long direction.
But i re-measured, and it seems that the model has small error too.

From the model: inner length = 127.34079 measured from print 127.2
phone 127.75

inner width = 65.443081 measured from print 65.3
phone 65.0

I just ordered some Premium PLA 90 from Orbi-tech. Lets see is it any better, color selection is poor for 1.75mm (3mm better)

I think i have asked, but what cad do you use? possible to share originals under DWTFYWT-license ? or just for me, i'll buy you a beer or ES :)

Yes, there's is a small error in model but not so big as that comment in GitHub indicates. I measured the dimensions with a simple ruler and made some scaling afterwards so there's definetely small errors (+-0.5mm) + PLA shrinks a little.

I modeled the model originally with Autodesk 123D Design: https://www.123dapp.com/design
The .iges and .step can be found from here: http://relativity.fi/jolla_toh/3dmodels/ (I'll add the DWTFYWT-license). Those were converted with FreeCAD from .stl back to solid models. I can of course provide the 123D Design file too if needed.

oooh there is mi problem.
The triangular STL is almost impossible to edit... this has now been gone to the STEP file too... I'm just heating my printer up.

EDIT: Previous stl was crap. this should be better.

Have to move the power switch opening a little, and add a smal notch to the bottom edge

I looked at the frame with Netfabb Basic, and it marked the part as 'damaged'.
It seems something weird about the four corners...

Very interesting project.

I'd like to add serial port (UART RX/TX pins at least) capability to Jolla with I2C.

Are there I2C to UART converters that could do this ?
