I hadn't seen DuinoMite, that looks great for the "child hacker". Funny coincidence that they mention the same article!
I've also been enamoured by PICO-8, a programmable virtual game console - its retro aesthetics and ALL CAPS syntax remind me of BASIC. https://www.lexaloffle.com/pico-8.php
Edit: Interesting...the Duinomite folks even noted the "Why Johnny Can't Code" post: https://www.olimex.com/Products/Duino/Duinomite/_resources/E...
