The author created a unique TV remote control for their 3-year-old son using floppy disks, allowing him to independently choose what to watch. The system uses a microcontroller to read the disks and send commands to a Chromecast. The author's goal was to provide a tangible and physical way for their child to interact with the TV, rather than using complicated remotes or mobile phones. The project also aimed to teach the child about agency and independence.
