Watch This Man Flip a Classic Cellphone Right into a MIDI Controller and Play Daft Punk's "Round The World"
Artistic Daft Punk followers have used calculators and even Tesla coils to protect the robots’ legacy within the wake of their break up. However this one simply might take the cake.
James “poprhythm” Kolpack has repurposed an outdated cellphone and, by means of using an Arduino Diecimila system, turned it right into a MIDI controller and vocoder to play Daft Punk’s basic, “Round The World.”
“This challenge takes a classic contact cellphone and converts it right into a musical instrument, or extra particularly, a MIDI controller utilizing the push-buttons to generate the indicators for musical notes,” Kolpack writes.
As soon as the cellphone was taken aside, Kolpack started mapping the myriad of buttons and wires. He mentioned there have been a complete of 11 wires that may very well be mixed for 55 distinctive combos.
He then assigned frequencies to the dual-tone multi-frequency signaling keypad primarily based on its rows. These uniquely assigned frequencies generate distinct tones for every of the buttons on the cellphone.

As soon as the buttons and wires had been all mapped, Kolpack entered his Arduino and programmed the system to play a pentatonic scale and a serious seventh semitone, with a root word of C.
He then connected the cellphone’s microphone in order that it may very well be used as a vocoder, a hallmark of the Daft Punk sound. The cellphone was wired in order that the microphone would solely activate when the handset was lifted off of the receiver.
“Since this system has each word and vocal inputs, it is attainable to make use of the audio sign because the frequency modulator to a software program vocoder,” he writes.
