The Oscilloscope Graphic Artist DIY Workshop.
“The Graphic Artist is a pattern generator that is designed to use the CRT screen of an oscilloscope as a “canvas” and its electron beam as a high-speed “brush”. The real-time three-dimensional display on the CRT screen has all the delicate geometric beauty and detail of the computer-generated three-dimensional drawings with which we are familiar”
(Mitchell Waite, Popular Electronics November 1975)
The Oscilloscope Graphic Artist was a project 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.
Multi-disciplinary artist Alex Peverett will lead the workshop giving an overview of various vector and oscillographic video systems before embarking on the build.
Everything is included to be able to generate interesting Oscilloscope Graphics. The Oscilloscope Graphic Artist 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. (OGA GitHub link.) This circuit has been redesigned by Philip Baljeu.
The workshop has been generously supported by Thonk.co.uk and Andrew Duff will be supplying a number of vintage oscilloscopes from his collection - go easy on them!
