tl;dr this looks like a full stack description of a hobbyist scanning electron microscope [0]. 'Full stack', here, means gerber files of a pcb with an fpga that 'controls the beam and gets an image', 'gateware' to configure the fpga, and some python scripts that read an image from the fpga and serve it as a web page drawing to a canvas with shader instructions.
