The Oscilloscope Graphic Artist (OGA) project was initially designed by Mitchell Waite and published in Popular Electronics Magazine. The project consists of a Time Base Oscillator, two Shape Oscillators, a Detail Oscillator, two Phase Shifts, two Multipliers, and Signal Mixers. From this list you might think the project would be complicated, but it is actually quite easy and even beginners will be comfortable. Everything is included to be able to generate interesting Oscilloscope Graphics. The OGA can be powered from either two 9 volt batteries, or a eurorack power supply. Workshop participants will be walked through the operation principles and the construction of the project.
