I love this! I learned my first logic with Crocodile Clips: would simulate and solder a lot of D flip flop based logic before learning about microcontrollers (my first was Atmel AT90S2313)
I once worked on a problem: GPS tracking shipping containers, since one company had almost 1% lost/stolen each year. I had an idea of using AIS with Si4362 to get positioning data from the container ship itself, but it was nearly impossible to get access to reefer monitoring systems. We ended up just using 4G NB-IoT for coastal tracking and it did solve the problem
