the operator of a MIDI calculator


AJTurley lives out many a Kraftwerk fan’s fantasy as he uses his scientific calculator as a MIDI controller by way of a Basic Stamp board –

This is a demo of a project I built so that I could use my HP 48 to play a MIDI keyboard. The calculator is running a program that sends data to a Parallax Stamp Basic microcontroller over the built-in serial port whenever I press a button. The microcontroller is running software that converts the message from the calculator into a MIDI noteon or noteoff message that is then sent to the keyboard. This is a response to a poll in which a (small) number of users said they wanted the site to cover more calculator music.
