I do find SPI e-ink displays on taobao, not sure about touch: https://world.taobao.com/item/558792955821.htm

I guess that's an old habit from maintaining open-source projects, fully disclosed & all transparent policy sometimes make things overly complicated. My apologies for the bad writing ;-)

Please find J20 from the schematic https://github.com/cutiepi-io/cutiepi-board/blob/master/SCH_...

Libhybris would still be your best bet on re-using Android drivers..

Anything related to flashing eMMC, anything kernel related, especially KMS/DRM, bionic libc... etc.

If you don't find it limited with locked device, you're simply not playing hard enough. :-))

I do find SPI e-ink displays, but not sure about touch panels..

The original xo tablet rendering is super cool, very hard to compete :-)

I believe it's GPIO7-10, please find J20 from the schematic, hope we can free up more in the future: https://github.com/cutiepi-io/cutiepi-board/blob/master/SCH_...

I'm also excited about Pi4, but on the other hand worried about thermal issue...

That must be an American thing, in Asia it's at least 12 decimal places (jk).

Just ticked double opt-in in Mailchimp. But man don't troll me, I have that vapor sitting on my desk. ;-)

Because the boot loader is locked, so does its launcher, unless LauncherHijack installed and abuses Accessibility feature to draw Overlays on top of your screen....

Speaking of modifying existing hardwares, Nexus 7 is my personal favorite: http://i.imgur.com/8H9LH9U.jpg

fellow veteran, what happened to this cool device? :-)

There are just too many single board computers! We've chosen Pi Compute Module for its ecosystem and community.

Fair point, will update accordingly. I hesitate to say anything because we are getting mixed signals from Chinese manufacturers....

If it has a working OpenGL ES and EGL support, then it could be a very cool target to port!

You're in for a treat, we are making a "coding" layout for the virtual keybaord (with an ESC and a Tab key! ;-)

yes, and when you're done, it's portable.

Value proposition time haha :-)

1) you have access to the Raspbian and Pi ecosystem 2) it has actual usable UI, commercial-grade I would say

The whole idea of this project is to help makers to be portable with their projects. The display is optional.

Ohh we did exactly that! https://i.imgur.com/QTRagEP.jpg

But it's not scalable, and I'm not particularly good at soldering. ;-)

Don't know much about that pen thingy so no guarantee, but will definitely look into it.

I see you man, we created this project for the exact same reason. Instructions will be posted, with pretty pictures! :-)

Looks cool, maybe you can start building a PoC with parts like this 2-mics Pi HAT? http://wiki.seeedstudio.com/ReSpeaker_2_Mics_Pi_HAT/

thanks, it's definitely on our radar. :-)

hi, on Pi4 it would be something like "Linux raspberrypi 4.19.46-v7l+", it's totally confusing.

More info regarding Pi3 arch https://www.raspberrypi.org/forums/viewtopic.php?t=140572

Will see if we can source any higher resolution MIPI DSI display parts, the current one's cheaper though ;-)

As an open source project (we're not a company) we'll try our best, hope it won't affect by the trade tariff? :P

For price range I would say kano computer kit touch or raspad tablet are all good products and provide good reference.

Form factor is one, also proper power management is very hard to get right with Pis.

Of course we made our first prototype with Pi3, and it ended up looking like this: https://i.imgur.com/gqUAdDa.jpg :P

Oh by the way we're not using HDMI display so it'll be cheaper (and thinner) too.

Sorry the UX is still under development, will be release when it's ready.

As a long-term Qt user, you can find my other tablet-related projects on Github, for example the browser https://github.com/penk/SlateKit/tree/master/Shell

We're using the MCU to swtich power source between USB charging or battery, using it's ADC to serve as a voltage divider to get actual AD value from the battery, and a MP2636GR chip for charging and voltage step-up.

So yay battery percentage! ;-)
