Latest pictures, click here (http://talk.maemo.org/showpost.php?p=1408719&postcount=118)

The OLED display is mono gray-white'ish (not blue as seen on some photos)
Size of the display is 0.96" with resolution of 128x64

It has proximity sensor to switch it off when TOH facing down or in your pocket. (has also ambient light sensor which might be used to control brightness (dimm when dark) )

It is controlled by daemon (systemd service) which is installed automatically from Jolla Store like ambience.

Thank you to you all for being so supportive on this project!

Hooked up an OLED display to Jolla

my I2C probe shows green at 0x3C:

Modified my app a little

and sent some text on the display
https://lh4.googleusercontent.com/-JJMN1FJge4Q/UsRQVKW4zyI/AAAAAAAAF_w/B2bd3MGtvWY/w465-h825-no/14010002.jpg

And with some more coding, i'm now at this point: watch in Youtube (http://youtu.be/AlNcas0HI2M)

The display is this here: datasheet (http://www.gemmarduino.net/PM1/00100-101/LM096-128064.pdf)
e.g. from Aliexpress (www.aliexpress.com/wholesale?SearchText=lm096-128064&catId=0)

(ordered some bare white ones for the final prototype)

Modified the display by removing the 3.0V regulator, replaced it with silly resistor divider to generate 1.8V logic supply (needed because I2C is 1.8V)

Interface uses ioctl to talk over i2c
file=open( "/dev/i2c-1", O_RDWR )
ioctl( file, I2C_SLAVE, 0x3c)
write(file, buf, len)

Very interesting!
So, there are seem to be two more contacts in the middle of the body (near +5V and GND contacts) and four contacts on the bottom parts that are not emerging to the surface.
Did you notice if there was some corresponding contact on the inner side of the black cover you removed (probably for some antenna) or are they only test/diag points?

This is very cool work. :)

Would be interesting if this or something similar also works with e-ink/epaper displays.

By the way, do you know how much power this setup draws?
Maybe even how the power consumption is split up between the display and the i2c controller?

Personally, I'd love to have something like this just with an e-ink/epaper display (in order to not drain the battery too much).

Edit:
A quick google revealed this:
http://www.youtube.com/watch?v=E05Azzcz5yg
http://www.youtube.com/watch?v=qPaNMrFXsqM
So, it looks like e-ink should be possible too.

Edit3:
Another interesting keyword seems to be "chip on glass".
These things are said to be very flat and come with an i2c chip built-in.

Would be interesting if this or something similar also works with e-ink/epaper displays.

I have done one project with kindle epaper display, and it did need lots of strange voltages, (e.g. +/-15) and somewhat complex interface, maybe easiest to have small processor to manage the drawing to the display itself (arduino tjsp) and just pass image over the i2c.

pros for eINK is to have zero power consumption, and even if having additional cpu for drawing, it needs to be powered on only when updating the screen.

I have also this BADGEr (http://wyolum.com/projects/badger/) and it is good reference design. maybe worth trying someday with Jolla.
https://lh6.googleusercontent.com/-mzEwSFfa1as/Ujvw7Q3RXKI/AAAAAAAAExU/TGf-k3T59-E/w1480-h833-no/13090035.jpg

This OLED has actually SSD1306 controller as COG (chip on glass) on it. The PCB where it is connected has only stepup converter which makes +9.5V for the display, but the SSD1306 has internal charge pump so that is not necessarily needed.

ATM power consumption seems to be about 100mW due my bad 1.8V "regulator" and non-optimized settings.
currently doing test how much it will drop my battery % during night. It should be easily get down to 50mW

Another display that could be interesting to try, depending on the use case, is the Sharp "memory LCD" e.g. https://www.adafruit.com/products/1393 (low power as an eInk and refresh rate as a LCD).
Although strictly speaking it requires a SPI bus.

(sorry, pic taken with iPotato)

Just wondering if the plastic from your printer is otherwise sturdy enough for OH?

I mean, if you needed to do fair amount of switching between other halfs. Do the usual 3D printer materials stand lot of wear and tear?

minimos

2014-01-02, 10:26

Nice!
Q1: How the thickness, do you need some extra mm to accomodate the screen?
Q2: Do you have still the display connected to the i2c contacts with wires & scotchtape, or did you use some springy removable contacts?

Nah. this printer uses crappy PLA which is ok for prototyping.
There are materials that could be used (and printed at home) but intention is to order this from internet when finished e.g. from shapeways.

Yep. The OLED glass is about 1.6 mm thick, and PCB is 0.8 mm
I have to check what components i need on the board. atm i expect about 2mm increase in thickness.

Q2: Do you have still the display connected to the i2c contacts with wires & scotchtape, or did you use some springy removable contacts?
They are with scotch tape/wire still...
I made a custom pcb that has matching pads for the phone pogo-pins (pins on the phone side have the springythingy)

Update.

SW
I have now achieved writing a service/daemon which is on D-Bus systemBus, and managed to configure policies so that it can own a name and be communicated with. Also configured systemd to start it at boot.

Now i can access the rear I2C bus and V33 output through D-Bus from normal application without starting it as root.

HW
I think i will do board as FPC - then i can keep height in minimum.
Thickess increase should be ~1.5mm, which is thickness of OLED glass.

Help...Hjälp...Apua...

Can someone dig/hack/design/suggest me a font to show big time on the screen? There is space of 128x48 pixels.
Numbers 0..9 and : needed. Preferably fixed width of ~28 pixels, 16 px for : .

Height max 48. (Width adjusted to what looks nice)

something like this:

23:56
28+28+16+28+28

in 32-bit hex words arranged to table, right aligned (leftmost 4 msb bits wasted.) one word/pixel row of character.

There is 128x16 free space below, but i think there could be notification icons tjsp,

herdem09

I can suggest using fixed-width fonts. Otherwise arranging spaces between characters might be problematic.

For example with fixed-width courier new font:

Did you have a look at the various graphics libraries available to support OLED in Arduino projects? I bet there should be some alarm clock project that uses nice big digits.

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...

droll

2014-01-09, 11:32

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.

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.

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?t=91535&highlight=i2c&page=18

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.

So, this is a sligthly thicker TOH cover that has space inside to allocate the screen, right?

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.)

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.

...about 0.5 mm error when comparing to the 3D model in length

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 (http://www.orbi-tech.de/shop/3D-Filaments/PLA/175-mm-PLA/Premium-PLA-90-175-mm-natural::297.html) from Orbi-tech. Lets see is it any better, color selection is poor for 1.75mm (3mm better)

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.

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 ?

--> either SC16IS750. Has 3.3V operation, but you'll need I2C levelconverter (e.g. PCA9517) and 1.8V regulator. Easier to interface to the 232 transceiver.

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.

kimmoli

2014-01-14, 07:50

... button in some form.

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...)

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...)

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.

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)

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:

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.

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?

kimmoli

2014-01-24, 19:37

...mentioned wanting to use a flex PCB.

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..

I must say I do not regret having raised my hand when you told about the first 5 OHOLED 40 € each. :)

Too bad the Sculpteo parts have a minimal thickness of 0.5 mm (even though total thickness of the OH remains unchanged), this may trap more dust and look a little bit less good. But there are constraints and that OH will be awesome anyway! Impressive work!

Just one question: Is the 'TOHOLED' text and your logo going to be on the final model as well?

Next version will have these on inside. It has been easier to check that the print starts ok with some details instead of just a large flat area. (first layer is sometimes tricky)

ATM these are negative, so they make the plastic thin and fragile on those places.
I could easily push my finger through the 'derp' (then it looks like this http://3.bp.blogspot.com/-sJJDxcXZbXA/UO2z-0H1guI/AAAAAAAAAC0/fD6Y26KnjOk/s200/Facepalm.png)

White, black, red, green, blue or yellow, they say. Black is not an option to me. I'm sort of used to Jolla meaning phone with dual colors.

I prefer this white one.

It makes no big price difference to have different models when ordering from sculpteo, so maybe this will be a option too.. :) if you insist. (just saving 1€ each when more than 5)

I have also PLA-90 in 'natural' color, grayish white. I haven't tested it yet... (Also white, red, green and blue PLA, transparent, Glow green in dark white ABS (which from i cant print this large parts))

Good to know there are actually additional colours when you order, the panel they show for polished plastic is not very appealing to me (colours are too "raw").

Since you bring this up, best to ask kimmoli:

Since you're working on several OHs, is there any chance of assorted features being combined into single OH plates?

We have a qwerty OH, a wireless charging OH, this OLED OH all in development (plus others).

I could see a OLED or eInk + wireless charging OH...maybe with one or two other tweaks that would be useful when the phone is "at rest".

And then the Qwerty with an extra physically "small" option for using when the phone is "On the go". Maybe integrate a full feature NFC tag?

The specifics don't matter, I'm not trying to ask that specific OH's be made. Instead, I'm just curious if there are any plans to combine multiple features into one plate?

kimmoli

2014-01-29, 05:43

I'm just curious if there are any plans to combine multiple features into one plate?

We are in early phase of TOH developments here, so i think it is better to first concentrate on TOHs that do one thing.

Otherwise we might get something that doesn't fit nor vibrate.

When these one-job TOHs are up, tested on field etc. marketing stuff, there could be time for übertoh...

There is still some things that has to be clarified before i can sell these, but assembly will start during weekend.

The 3D print is still open - is sculpteo good enough? i did reorder sample and it should come next week.

The 3D print is still open - is sculpteo good enough? i did reorder sample and it should come next week.

While I like the polished plastic on Sculteo, it is rather rough and feels like paper on touch.

As I've said to dirkvl, I've heard that i.materialise.com is better quality-wise, though never ordered from them. Both sites offer sample kits for 30 EUR with 25 EUR off voucher for next purchase, so it is rather the same on that front if you stick with the one you get the samples from.

On the shipping side, i.materialise is better - they offer one day shipping for 14 EUR and 5 day for 13, while Sculpteo only have 12 EUR for one week (or more).

I am surely interested to have one,

just a few questions (faq to first post :))

What is the increase in weight compared to a normal toh-jolla?
what is the increase in "thickness" compared to a normal toh-jolla?
Is there any estimation concerning battery usage?
Will the toh be without the meme-head?
Will the "quality" of toh surcface be polished like in a normal toh-jolla compared to the demo-version, which seems a bit "unpolished"?

Edit. added more questions.

kimmoli

2014-01-31, 20:01

Here are some answers

What is the increase in weight compared to a normal toh-jolla?
with my current PLA printed one, weight increase is 2 g (total 143 g)
what is the increase in "thickness" compared to a normal toh-jolla?
About +1.8 mm (new thickness 11.7 mm ,original by spec 9.9 mm)
Is there any estimation concerning battery usage?
Some results, see here (http://talk.maemo.org/showpost.php?p=1408293&postcount=93)
Will the toh be without the meme-head?
See post #1. It will be available with or without (It will be on inside anyway)
Will the "quality" of toh surcface be polished like in a normal toh-jolla compared to the demo-version, which seems a bit "unpolished"?
TBD (demo is printed with my own printer.) Still looking for best supplier.
But it is kinda ok for me. not so slippery as the original toh. but looks like "selfmade" when taking a closer look.

minimos

2014-01-31, 21:49

what is the increase in "thickness" compared to a normal toh-jolla?
About 11.7 mm (Original by spec 9.9 mm)

I hope you mean that the total thickness will be 11.7 mm, not that the *increase* will be 11.7 mm. Right?

xkkkx

2014-01-31, 23:19

I hope you mean that the total thickness will be 11.7 mm, not that the *increase* will be 11.7 mm. Right?
I think that's the case as he is comparing directly the original total thickness 9.9mm to TOHOLED 11.7mm

Rauha

2014-01-31, 23:26

Is it not pretty clear from the pictures that total thickness won't increase by 118%?

Phone + TOHOLED = 11,7mm

For TOH with ink paper, You can count me in!!!

So does this mean that you'll wait for that and skip oled?

kimmoli

2014-02-01, 17:33

I tried i-materialise --> not like. :(

first it took several hours to get my account confirmation link.

Then it says minimum wall thinkness 0.8 - 1mm, detail 0.3mm tolerances +/-0.3mm

And then very limited color selections; and this part is too large to be polished (tumbled)

But finally got test of natural polyamide ordered. lets see.

kimmoli

2014-02-01, 19:34

Made test-order to shapeways too. (estimated arrival here by end of month :( )

(Their online quote does not give any volume discount)

For polished ones, they have also low count of colors compared to sculpteo. (see below)

I will check out also frosted plastics (https://www.shapeways.com/materials/frosted-detail-plastic) (it is the only material they print down to my current wall thickness) frosted ultra detail is what they print to my original thickness requirement of 0.3mm - but that costs about 50€...

sombrer0

2014-02-01, 21:47

Kimmo, will you sell your toh as plug n play or diy kits?
Would like to have just the parts and doing the assembly and soldering myself. I have no idea of what i would be doing though, so I would need a guide.

Mohjive

2014-02-03, 11:48

Just for clarification, I'm interested in the DIY variant as well. I can also provide soldering/construction for anyone close to Linköping, Sweden, or anyone willing to pick it up here, for those that prefer that (and to relieve @kimmoli from time-consuming assembly, so he can focus on design).

kimmoli

2014-02-03, 12:18

DIY kits are ok for me.
PCB + parts + bom/assy drawings.
How about the 3d print, are you able to manage that 'diy' too?

kimmoli

2014-02-03, 12:25

Seems that no printing 'factory' is able to fullfil my requirements of 0.3mm thickness in certain part of the TOH, bezel around the display.
(except shapeways frosted plastic Ultra detail which is $$$) (And my own printer)

Summary of wall thicknesses with reasonable priced coloured materials;

Sculpteo 0.5mm
Shapeways 0.7mm
i.materialise 0.8mm

I have contacted now couple of local suppliers here in Finland, lets see what they can do.

(same issue is then with eink/epaper TOH too, so finding good supplier now makes life easier in future)

egnat69

2014-02-03, 13:59

so we basically have to decide if 0.2mm are worth the premium price-tag?

would glueing something like a .5mm square plastic foil onto the display to even it out be an option?

.5mm clear acrylic sheets should be available quite easily, it's probably just a question of finding the right glue (something like the one that's used for screen protectors...

Mohjive

2014-02-03, 20:57

@kimmoli: unfortunately no 3D-printer available here. But if provided with CAD-files and BOM, I could maybe produce circuit-boards in our (small) facility.

Can you share the Cad-files and/or BOM now? I haven't really look into TOH development yet, and are interested getting some inspiration. :)

sombrer0

2014-02-03, 21:04

If I buy the DIY kit, what must I do to print/order the case from eg. shapeways?
Sending my jolla back for repair and can't afford to order toh now if I must pay to get the phone fixed(I'm a student...)
Can't wait to buy either this or your e-ink project, wich ever is available once I get my phone back.

kimmoli

2014-02-03, 21:06

Can you share the Cad-files and/or BOM now?

I would like still to keep my baby home to just make sure everything is ok.
Today i tested it in another jolla, and when i installed it back to my own there was a 'jealous-latchup-event' and display was showing only noise.
After few minutes not-connected and changing 'WTF' to <3 it was up and running again. Might be reset timing issue.

(And i'm making some extra PCB, so no need to make them DIY - or do you mean about the assembly/soldering process?)

kimmoli

2014-02-03, 21:10

Mohjive

2014-02-03, 21:57

I meant the assembly, not PCB printing (I cannot do PCB-printing either).

Have you looked at http://i.materialise.com/ ? They seem to be able to do 0.3mm details with ABS. And they have a lot of interesting materials, like alumide and resin (and even titanium)

Mohjive

Nice spotting... it is still missing from these prototypes, but should be there in next version.

It triggers NFC and eeprom read.

2014-02-07, 07:57

for future iterations (like when kimmoli starts to make his living only by selling TOHs ;D) it would be a nice feature to have an nfc-tag that installs/autostarts the engine for the oled-display... does anyone have experience with that stuff?

kimmoli

2014-02-07, 08:09

atm it is planned that the oled toh will use nfc for such purpose, there might be even special derp-ambience... am i promising too much :p

Reset issue is now confirmed. seems that the I2C lines leaks enough supply voltage to the oled controller chip.
I have simple RC circuit on reset pin connected to the 1.8V regulated supply, but seems that it does not go low enough to fully reset the chip. When writing bad register values, those are not going back to reset values unless the toh is completely removed from phone for about 30 sec.
Might need to add there active reset driver or something... have to check for a good and lowcost solution. maybe MCP120 or similar.

Sculpteo print arrived.
print size has rather big difference to another print.

Additionally none of the these test prints does not work :mad:
have to check what is wrong with dimensions, but seems that the PCB does not have contact to the pogopins at all.

This will be a rocky road

I might have mine tomorrow at work if lucky, otherwise probably the day after. :)

Any software available already Kimmo?

Soon...

I will try to make the rpm package ready today, but if you start getting them earlier, i will ofc send those couple of 'raw' files needed.

We can track possible bugs here for now (as there should not be so many :cool: ) - Every HW is little different, so the ALS/Proximity values are now hard-coded by my unit and might need some per-device tuning. But if that is needed, i will make it "UX".
