// Daisy Bell
“Daisy Bell” is the first song a computer ever sang, and the one HAL 9000 sings as it’s shut down in 2001: A Space Odyssey. SAM only speaks text, it has no idea what a musical note is, so this reads the melody straight out of a MIDI file and sings it syllable by syllable, one note’s pitch and duration at a time.
I'd love to tell you more.
// LED Matrix Simulator
I’m building a small LED matrix display running its own firmware, and flashing the board just to check whether an animation looked right was slow enough that I stopped doing it as often as I should. This runs the exact same menu and playback code as the real firmware, in the browser, against a real animations folder read straight from disk.
