Arto Chydenius is a Helsinki-based software engineer with a special interest in the technology and visual aesthetics of the past. After graduating as an M.Sc. in software engineering and working many years in the software industry, he decided to focus more on the creative aspects of computing and started M.A. studies in Aalto Media Lab, Helsinki, in 2018. At the moment Arto has been experimenting with microcontrollers as a means of creating oscillographics, and as a consequence, building his own open-source programming library Voltage for such devices. His personal interest is especially in three-dimensional vector graphics familiar from the arcade games and movies of the 1970s and 1980s.
Microcontroller-Based Approaches for Creating Oscillographics
While the vast majority of oscillographic tools today rely on using computers with external audio interfaces, there have been a few projects based on using microcontrollers—such as Arduinos or Teensys—instead. The presentation introduces some of these projects and the approaches used, including the author’s own programming library. The presentation also discusses some of the concepts and algorithms of early computer graphics—of which some have become obsolete due to the advancements in graphics hardware during the recent decades—but which interestingly are still relevant in context of oscillographics today.
