 Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me. |

Definitely with the PicoMite using PIO - would be much better as no jitter |

nice ! For beautiful laser effects you can also glue a mirror to a loudspeaker and then control it with different frequencies Ron |

I had a gas tube laser and it used 2 stepper motors with mirrors. lasers are cheap and the hardware/mirrors etc. also... but why a raster scan text display? A really cheap vga projector? they actually work.. in a dark room. |

Hi lew, Pretty obvious the mechanics are the challenge. The software, using PIO, looks very doable. Even the time synchronisation between mirrors. Constant speed on the motor is a dual pwm. Picomite can do it. Volhout PicomiteVGA PETSCII ROBOTS |

With 8 cheap lasers and 1 mirror you can make it much easier. Frank |

Note: This style of laser tech was being done in the 1970s |
