Dot Matrix Synth
by Laughing Boy at 1:03 am EDT, Jun 15, 2003 |
] I've modified an Epson LQ-500 dot matrix printer into a
] musical instrument. The project has now evolved into two
] different versions. The original project had two
] independent sound generators: a tape based sound
] generator similar in concept to a mellotron and tones
] generated from the print head. The new version of the
] software is written with the concept of turning the
] printer into an instrument without any physical
] modifications to the printer. Since the tape mellotron
] setup does require some modifications to the printer, it
] is not part of the new version.
]
]
] Most of the changes to the printer operation are done by
] changing the software. The printer is controlled by a NEC
] 7810 microprocessor that runs off code on an EPROM inside
] the printer. I have reverse engineered most of the basic
] operation of the printer and now have control of the
] paper feeder motor, the print head, the lights, the error
] beeper, and can read the buttons. |

There is a redundant post from Dementia not displayed in this view.
