I don't give complete instructions for this because it's intended to be a student project where the student must do their own design, construction, and testing of the vertical and horizontal control circuitry. However, the basic LED array and driver circuits are downloadable as a PCB layout file and schematic diagram: PCB layout file (using gEDA's "PCB" circuit board editor software: www.ibiblio.org/kuphaldt/socratic/model/apps/LED_oscope_v2c.pcb Schematic diagram: www.ibiblio.org/kuphaldt/socratic/model/apps/LED_oscope_v2_schematic.pdf
