A while back I built my own remote control unit for controlling a Roomba using atMega328s and nRF24L01 units. (https://www.youtube.com/watch?v=LKGvjCaPTRQ&list=PL05patmtD9AsCZP71REg0Il5_n6Sb437a)
I've seen other people who have remote-controlled devices using radio controllers that were intended for cars, toys etc.
It would be great to see an episode where Ben takes a radio controller and repurposes it to control another device. I'm interested to see how to reverse engineer the controls to map to different actions.
Thanks for listening.
