There seems to be a model of the ASML TWINSCAN NXE3400C which shows the inner workings, but doesn't show on the ASML site. Would be neat if someone could track down the build instructions.

There is another set available on their site.

I've been using the Onyx Boox Max 2 for a couple years and it's a pretty good device. When I purchased it they stated they would update the Android version, but they never did so it's stuck on Android 6. For reading PDFs it's good and there aren't really any competitors with this large of a screen. I'll often read books in dual page format, or read manuals in single page.
The device crashes frequently if you try to use any third party apps, and the pen has major lag if you're not using their notes app. Don't turn on the wifi or else the battery drains extremely fast. Make sure you don't leave it charged overnight or else the battery might balloon and explode. When this happened Onyx replaced my battery for free.
Despite these shortcomings, it's still better than the Sony digital paper (which I've also used and sold). The pen is pressure sensitive, which isn't in the Sony. The writing experience is worse than on the Remarkable, but Onyx has a bigger screen.
I'd recommend Remarkable if the screen size is good for you. The software is a lot more stable and the device is a lot more polished in general.
The BeagleBoard BeagleY-AI that was just released costs $70 at 4TOPS, equal to the Coral which is $60 for the USB alone disregarding the cost of a Pi [2]. It just came out, but BeagleBoards have quite a good community reputation and because the hardware is more open, easier to develop into a commercial product. The older BeagleBone AI-64 has a processor that supports 8TOPs, and TI has processors that go up to 32TOPs if you have the skills to create your own board (I don't).
I would not recommend developing with the NVIDIA Jetson unless you have particularly deep pockets and like to use an out-of-date toolchain. The latter isn't too unfamiliar to the embedded world though.

Transistor gates act as capacitors in a way. This capacitance increases the delay between switching on/off. [1]
To lower this delay, we can shorten the transistor gate. We've hit a wall with how small we can shorten this length, and it is exceedingly difficult to make smaller gates without running into quantum effects.
Higher electron mobility means that the delay inside the gate is reduced, allowing faster circuits.
