Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Anyone know where I can fabricate a case for my Raspberry Pi project?
I like the CutiePi design.
- Custom charges from Taiwan

Resources to learn how to create a display-driving embedded linux application?
One decent example I can think of off the top of my head is the CutiePi, which is a cool little tablet with a UI built with QML.

CutiePi – thinnest Raspberry Pi 4 tablet
Personally I've been waiting for the CutiePi to use the CM4, and now they have updated the platform I'll probably get one myself.
Having said that it looks like a missed opportunity here for supplying the masses with a Linux device for learning purposes especially in the developing countries during the pandemic or not. I think the best price for this device is USD$100 as promised by the ill fated OLPC laptop project. Perhaps USD$100 is not much by developed countries standard incomes but in most part of developing countries you are very lucky to have USD$100 disposable income at the end of the month (or year) to buy your children a tablet/laptop/computer.
It also interesting to note that the 2019 Galaxy Tab A (without LTE) with similar specs (8", 2 GB RAM, etc) to the CutiePie is probably cost about USD$100 nowadays [1].
The good news is that since CutiePie is based on open hardware system perhaps someone can use the open design to come up with a cheaper version closer to the USD$100 price point[2].
p/s: RPi 400 costs about USD$100 but the fact it does not has a built-in screen limits it impacts on usability department for children

CutiePi – thinnest Raspberry Pi 4 tablet
A friend & I have a dream of building an E-reader based on the 10" ED097OC4 E-ink display that was built into the Kindle DX and can now be had for around 30€ (old stock?).
Most parts of the stack are conceptually figured out:
A Pine64 SOPINE module (comparable to the Raspi CM, but cheaper), a Linux DRM driver based on tinydrm (https://github.com/notro/tinydrm) or gud (https://github.com/notro/gud/), as panel driver either vroland's ESP32 based EPDiy (https://hackaday.io/project/168193-epdiy-976-e-paper-control...) or a custom FPGA solution.
What's really missing and what 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 them to size doesn't seem feasible (or is it?), perhaps the most DIYable would be an infrared solution (like early kindles have), but on that topic there's a distinct lack of DIY materials.
A button-only navigation would really suck, since even KOReader (the absolute minimum application to run, preferable would be a full Wayland desktop) doesn't seem to be compatible with that.
I figure this is the best place to ask: Does anyone have an idea how this could be solved? Also, would anyone be interested in E-reader kits like that?
What are some alternatives?
