       | I have this on my list as TODO for my kids. Mine will be with:
       | 
       | - 30k mAh battery, instead of 5k

       | - use of RPi HQ camera (12 MP, not 5)
       | 
       | - 8 GB RAM (not 2) & a 1 TB NVMe SSD
       | 
       | Projected price for above components is ~ $350. I want to
       | introduce them to Linux (they do everything on Windows for now)
       | and by exposing the RPi's GPIO to also introduce them to
       | robotics.

       | the Pine Tab that is one and a half?
       | 
       | Thing is I am desperate to have a tablet with decent capabilities
       | (and at about $500 price point) that is _not_ a consumer device,
       | and I need it nine months ago. Too late now - up to my eyebrows
       | in Apple iPad nonsense.
       | 
       | I have been working on a application that uses a dedicated tablet
       | (iPad FFS, why does Apple hate developers so much? I spent thirty
       | years away from them - how fantastic they used to be... I
       | digress) I would really like to have complete control of the
       | tablet that the users are out using - controlling millions and
       | millions of dollars of assets and revenue - not have a consumer
       | device with all the cruft that implies.
       | 
       | Whilst it is possible to strip capabilities off of a consumer
       | device, as a developer I am not in control of it. The only
       | confidence I can have in it is based on Apple's engineering, and
       | as a developer I have a inside look at that, and it is not what
       | it was (or seemed to a younger me thirty years ago).
       | 
       | Nice start, too little, too late - for me.

       | I think there's a great niche for "embedded" devices around the
       | home -- weather readout panels, lighting controls, music player,
       | intercom, etc. -- but glowing rectangles mounted to the wall are
       | just too... glowing. E-ink panels is where it's at, and a
       | Raspberry Pi powering it is perfect.
       | 
       | Unfortunately, the only real general-purpose e-ink tablet I'm
       | aware of is the Boox, but their models are all $400-800, which is
       | _way_ too expensive (when similar tech in a Kindle is $80).
       | 
       | All I want is a relatively low-power, low-memory, low-storage
       | touchscreen e-paper tablet (i.e. specs of an old Kindle) that I
       | can run Linux and a WebKit browser on.
       | 
       | And I want them to be cheap enough in bulk so that other
       | companies and startups can build home devices _on top_ of them to
       | resell.

         | How close would a hand-crank mechanism be to driving an e-ink
         | tablet for a useful amount of time? A quick look at a clockwork
         | crank-wind-up torch shows it has 300mAh battery and 30hrs of
         | blinking SOS LED on a full charge, and they claim 1min of
         | winding gives it 2hrs of blinking LED, so roughly 20mAh per
         | minute of winding. How much computing can one do in 20mAh?
         | 
         | "Clockwork radio" and no-battery crystal radios must be quite
         | low power, and one approach for e-ink screens is to only update
         | a small changed area of screen at once. The FireBeetle ESP32
         | can deep-sleep on 0.011mA [1] and reference is at 39mA. Maybe
         | 1min of clowkwork winding could drive it at reference power for
         | 30 mins, and half-power for an hour?
         | 
         | What kind of computing UX/UI/OS could there be with primarily
         | audio feedback[2] using a low power earphone, e-Ink style
         | screen updated only on demand?

             | I would suspect the boox actually has more capable hardware

               | You are right that $185 might be a more realistic
               | pricing, but that's a 68% increase over the price of the
               | $110 Kindle so I wouldn't say that they are similarly

         | 
         | Most parts of the stack are conceptually figured out:
         |

         | 
         | What's really missing and I just can't figure out is how to get
         | a touch input layer on there. Because the format is so weird
         | there's just nothing available off the shelf at a fitting size.
         | Cutting a larger one to size doesn't seem feasible (or is it?),

         | early kindles and old larger touch screens have, but on that

       | Their open source repositories are available here:

       | 
       | Note this isn't a tablet in the traditional sense. Think of it as
       | a Raspberry Pi with external touchscreen, camera, and battery
       | folded into a tablet-like form factor. They've done some cool
       | things with software and hardware to bring it all together, but
       | it needs to be viewed as hackable open source hardware and not a
       | competitor to a cheap Android tablet from Amazon.

         | The reason they're late is because they switched from the

         | announced/released) Raspberry Pi 4 compute module very late
         | into the project.
         | 
         | I would have preferred if they had shipped what they had,
         | instead of delaying the project for that upgrade, but it seems
         | most backers preferred to get the shiny new thing, even if it
         | meant the project was delayed.

       | I am not familiar with the Linux Ecosystem, so I don't understand
