The project PHOENIX, created by Ajith Kumar, from Inter-University Accelerator Centre (IUAC) in New Delhi, is aimed at creating “Physics with Home-made Equipment and Innovative Experiments” (Phoenix). The popular boxes distributed by this projet are named expeyes, kuttypy, microhope. Each of them is based on a microcontroller, and provide their unique features thanks to the microcode burnt into those microcontrollers. More information is available at https://expeyes.wordpress.com/phoenix/ This package provides the source and the binary formats for that firmware.
