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.

Reviewing 1 year of my progress from practicing mental calculation (flash anzan)
yikes! do you have javascript blockers? The site is unusable without javascript.
FWIW, it's a custom rerender of https://github.com/whacked/cow/blob/main/learning%20soroban%...

Braille Is Alive, Well, and Ever-Evolving
Seems like I went down a similar path. Emacs user, brltty, the shebang, but not together :-)
Maybe my experience will be useful to you. Do it for the plasticity.

Ask HN: What was the best software that you used during 2022?
one combination I came to really love this year is babashka (https://github.com/babashka/babashka) + websocat (https://github.com/vi/websocat). I wrote about a method of live web programming with this pair at https://github.com/whacked/cow/blob/main/a%20technique%20for...
babashka isn't strictly necessary; you can also pipe plain text, but pushing hiccup expressions to the browser DOM from the REPL with instant feedback has opened a new world of interactive programming for me.

Braille Is Alive, Well, and Ever-Evolving
(If you find a way to buy them i would greatly appreciate you sharing it)
PS : These cells use 200V DC to work so your project will need a DC-DC converter. You can search for similar speccs to the official one on aliexpress or whatever https://metec-ag.de/downloads/dcdc-converter-5to200v.pdf
Finally you would need a brain for all this which could be the raspi directly or you might opt for using the raspberry-pi (for the ebook manipulation, character-to-dot conversion etc.. unless you decide to pre-format the files) in conjunction with an arduino (for the signal transfer/propagation.. you know sending the )
Take a look here for some software inspiration (it also explains the signals the braille module would be expecting but you are better off looking at the Datasheet for anything serious): https://github.com/bertrandmartel/metec-braille-driver#more-...
Good luck.

A nice video from "Applied Science" about a one Cell driver DIY project (He is i believe, using the P16 cell from metec) might help you decide whether to buy a backplane-driver or make your own [also the idea or putting a push-button underneath the braille-cell might be interesting to you for a selection mechanism maybe?] : https://www.youtube.com/watch?v=Ss-Fux86doQ
