So how about an engine that sings? French technicians have programmed the controller for an Asiatech 10-cylinder, 750-hp Formula 1 engine (based on a Peugeot design), to run through various rpm/note ranges in the correct sequence to play a rousing sequence of musical notes. With five combustions per revolution at a frequency per second of 12/rpm [60/(5 x rpm)], the engine can produce revs for a particular note by multiplying the note's frequency by 12. For example, a 440 Hz A note needs 5,280 rpm and a C needs 3,139 rpm. For a demonstration of "When the Saints Come Marching In," go to http://astro.temple.edu/~kmr/Chauffe2.mp3.
These are the toys that inspired budding engineers to try out sublime designs, create miniature structures, and experiment with bizarre contraptions using sets that could be torn down and reconstructed over and over.
