Re: Jolla OtherHalf OLED display
Hope you dont want to remove the battery....

Re: Jolla OtherHalf OLED display
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. |

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...) |
Re: Jolla OtherHalf OLED display
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...) |

I opened own thread for eInk OH --> http://talk.maemo.org/showthread.php?t=92408

SW Got connected with ofono to get signal about new SMS... Code:
static const QString service = "org.ofono"; |
Re: Jolla OtherHalf OLED display
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) |
Re: Jolla OtherHalf OLED display
Awesome, really. Now finish it and take my money! :]

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: https://lh3.googleusercontent.com/-R...o/14010013.jpg |
Re: Jolla OtherHalf OLED display (Waiting for PCB)
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). |

Re: Jolla OtherHalf OLED display (Waiting for DHL to make delivery)
i want one too
|
Re: Jolla OtherHalf OLED display (Waiting for DHL to make delivery)
This ticks off one of the things on my fundamental features required before getting a jolla ;D

Re: Jolla OtherHalf OLED display (Waiting for DHL to make delivery)
ahoy, they arrived on time!

Re: [WIP] Jolla OtherHalf OLED display
Very nice, count me in too!

Re: [WIP] Jolla OtherHalf OLED display
More images of the PCB. ITEAD ENIG.
Taken with Jolla (Through Vision SX45) https://lh6.googleusercontent.com/-6...140123_007.jpg https://lh6.googleusercontent.com/-b...140123_008.jpg https://lh3.googleusercontent.com/-J...140123_009.jpg https://lh3.googleusercontent.com/-l...140123_010.jpg And silkscreen... https://lh6.googleusercontent.com/-u...140123_011.jpg |
Re: [WIP] Jolla OtherHalf OLED display
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 |

And for sure #1 is reserved already, guess to who :D |

Re: [WIP] Jolla OtherHalf OLED display
Count me in if this OHOLED will be merged with the Other Half Hardware Keyboard project

Re: [WIP] Jolla OtherHalf OLED display
Like very much, I'm in for one when ready

I would also be in for one if anymore possible!:)

Re: [WIP] Jolla OtherHalf OLED display
Not even got my Jolla yet (in transit!!), sign me up for one of these OH if your doing > 5! :D

Re: [WIP] Jolla OtherHalf OLED display
What's the size of the screen? 0.96 or 1.3 inches ?
|
Re: [WIP] Jolla OtherHalf OLED display
it is 0.96"
|
Re: [WIP] Jolla OtherHalf OLED display
Just beautiful. If you are ordering a second batch, please count me in for one too :)
|
Re: [WIP] Jolla OtherHalf OLED display
What Juiceme said.
Would love to have one of these. |
Re: [WIP] Jolla OtherHalf OLED display
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: https://lh3.googleusercontent.com/-D...o/14010032.jpg Really thin 2-sided tape used to fix pcb to printed part. oled might need to be glued in place: https://lh4.googleusercontent.com/-7...140124_004.jpg |
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? |
Re: [WIP] Jolla OtherHalf OLED display
Quote:
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.. |
