Prototyping With a Vintage Plotter From 1987

  • by

David (the hardware guy on my blog) made this cool modification. He used the Aritma Minigraf 0507 plotter manufactured in socialist Czechoslovakia to draw an etch-mask directly onto a PCB. He added an ARM-based interface and created the software that can generate vectors out of hi-res images of boards.

Check the video description for more information (including source files to download).

Btw the new version he is currently working on has a laser instead of the pen.
