• PCBWriter hardware
• First demo PCB, completely populated. The chip in the middle is an Atmel ATtiny in a 32 pin, 0.5mm pitch QFN package.
• Polygon mirror assembly opened, showing the beam path using a low-power laser diode. (Note that the lenses were later removed.)
• laser driver
• laser scanning a line
• test PCB being etched
