Add a RPi projects section parallel to micro:bit. May involve a common/share electronics section vs repeating in each.
Add broader interests in technology, tech history, retrocomputing, software structures, computational thinking etc.
Medium term:
Add a TOC and 'Recently Added' navbar
Extend projects with more teaching notes, differentiation and extension activities.
Soon:
Sensors > "It's all about the data" (overview on elements of profiling data for patterns, noise, filtering, signal matching, conditioning etc. to find the information you really want, e.g. heart beats in pulse sensor waves).
Sensors > BBC micro:bit integrated sensors
Sensors > Ultrasonic
Projects > Pilot REPL bridge to PC based apps / websites
