cant wait!
btw you should have copyright on the doodle face, just someone at crackberry with the same!

Re: [WIP] Jolla OtherHalf OLED display (POLL!!!)
 

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).

Re: [WIP] Jolla OtherHalf OLED display (POLL!!!)
 

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.

Re: [WIP] Jolla OtherHalf OLED display (POLL!!!)
 

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

• 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.

Re: [WIP] Jolla OtherHalf OLED display (POLL!!!)
 

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

Re: [WIP] Jolla OtherHalf OLED display (POLL!!!)
 

I think that's the case as he is comparing directly the original total thickness 9.9mm to TOHOLED 11.7mm

Re: [WIP] Jolla OtherHalf OLED display (POLL!!!)
 

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

Phone + TOHOLED = 11,7mm

Re: [WIP] Jolla OtherHalf OLED display (POLL!!!)
 

Well, he could have fit an Arduino in those 1.1cm :)

Re: [WIP] Jolla OtherHalf OLED display (POLL!!!)
 

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

Re: [WIP] Jolla OtherHalf OLED display
 

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.

Re: [WIP] Jolla OtherHalf OLED display
 

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 (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€...

Re: [WIP] Jolla OtherHalf OLED display
 

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.

Re: [WIP] Jolla OtherHalf OLED display
 

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).

Re: [WIP] Jolla OtherHalf OLED display
 

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

Re: [WIP] Jolla OtherHalf OLED display
 

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)

Re: [WIP] Jolla OtherHalf OLED display
 

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...

Re: [WIP] Jolla OtherHalf OLED display
 

@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. :)

Re: [WIP] Jolla OtherHalf OLED display
 

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.

Re: [WIP] Jolla OtherHalf OLED display
 

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?)

Re: [WIP] Jolla OtherHalf OLED display
 

I will provide STL file to print or order one (or lets see if i am generous due your situation ;) )

I will now update the original post about DIY kit.

Re: [WIP] Jolla OtherHalf OLED display
 

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)

Re: [WIP] Jolla OtherHalf OLED display
 

And I do understand you caring for your baby. I'm just fascinated and curious. :)

Re: [WIP] Jolla OtherHalf OLED display
 

It is not the details, it is the wall thickness,
ABS Minimum wall thickness 1 mm (no good)

Re: [WIP] Jolla OtherHalf OLED display
 

You need to up the ante and go for 'OLED display - titanium edition' :D

Re: [WIP] Jolla OtherHalf OLED display
 

I'd like to order this. Am I too late, vote's been closed already?

Re: [WIP] Jolla OtherHalf OLED display
 

some photos of first sample. (I have to work on the support-bars as the material is translucent)

Re: [WIP] Jolla OtherHalf OLED display
 

Noticed that you don't have a cover detection "rib". Is that only used for NFC reading or general cover detection?

Re: [WIP] Jolla OtherHalf OLED display
 

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

It triggers NFC and eeprom read.

Re: [WIP] Jolla OtherHalf OLED display
 

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?

Re: [WIP] Jolla OtherHalf OLED display
 

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

(There might be some issues if the oled toh daemon rpm needs also pass harbour-rules)

Re: [WIP] Jolla OtherHalf OLED display
 

I'm in for derp-ambience!

Re: [WIP] Jolla OtherHalf OLED display
 

Derpiance? :)

Re: [WIP] Jolla OtherHalf OLED display
 

awesome! ;D

Re: [WIP] Jolla OtherHalf OLED display
 

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.
(note to self: RT9818C-29GV)

Re: [WIP] Jolla OtherHalf OLED display
 

Great stuff, I want one so please count me in if it's not too late (seems that I missed the poll, but would have voted: YES).

I just have one question abt the information displayed in the OLED; is it possible to have current date shown there (with time, battery %, and SMS info)? Does it fit and/or does it require some tweaks in SW-side?

Thanks for any info.. ;)

-jukka

Re: [WIP] Jolla OtherHalf OLED display
 

send me a PM so i dont forget..

It is just software, have to see what solution i come up with. too small is no good, maybe date could be shown only if there is no active notifications.

Re: [WIP] Jolla OtherHalf OLED display
 

sculpteo-print is taking roadtrip, France -> Germany -> Denmark...

Re: [WIP] Jolla OtherHalf OLED display
 

it might meet a few jollas on the way! :)

Re: [WIP] Jolla OtherHalf OLED display
 

Yeah, one might think that the shipping cost would warrant a faster method. Mine dragged for more than a week.

Re: [WIP] Jolla OtherHalf OLED display
 

one could always paint it?
