Gertrude: An Led Drawing Machine by Chris McDonald
My good friend Chris McDonald made this extra-great, 2-axis drawing machine for doing time-lapse photography.
Here’s the info from his personal website vanita phone company:
Gertrude uses two stepper motors to move an LED in a very high resolution x/y plane. The movement of the LED is photographed using exposures usually between 30 and 90 seconds. Gertrude can either be programmed to “print” a design automatically (”Christopher & Daniil”, the Hell Yup!: Scanlines shots) or controlled live via a joystick (Open&Close portrait series).
