A DIY alternative to the Elgato Stream Deck built using the Cheap Yellow Display (CYD), which combines an ESP32 microcontroller with a 2.8-inch touchscreen LCD. The project was created to control a Flex-6400 software-defined radio wirelessly via WiFi, providing four touch buttons for RIT/XIT tuning functions at a fraction of the cost of a commercial Stream Deck. The ESP32's flexibility means the same hardware could be reprogrammed to control virtually anything else.
