Well, unfortunately I have to earn my living and, thus, to concentrate on other things now. I had hoped to create more within the time I had but ACCK and AC-AC do not look all too bad for the beginning.
Concerning Bangle.js 2 and my CS lectures: well, definitely not during this semester (exam phase will start in three weeks).
At the beginning of this semester, I gave a away a few "Maker UNO"s and now hope to see what my students did with them by tomorrow or next friday.
For the next semester, I plan to concentrate on the RasPi Zero 2 as it covers everything - from "hardware computing" over development with Linux to Linux administration.
Therefore, I will definitely introduce the Bangle.js 2 as an example of what individuals or small groups can achieve today - but I doubt that I will start any projects for my students with it. Perhaps, however, I'll call for a small competition (letting students develop and publish their own software and/or hardware projects or even found their own small start-ups) and offer my Bangle.js development clock as a prize...we'll see
