Recycling, remanufacturing, refurbishing, repurposing and up-cycling are all ways to add value, reduce waste and lower the environmental impact of used objects. Through the notion of tinkering, we will explore how discarded objects can be creatively reused for utilitarian and artistic purposes. Through this process participants in the course will enhance their technological creativity and designing capacity. Using projects and experiential means (e.g. tinkering) students in this course will gain a deeper understanding of their creative process, improve their understanding of mechanical objects, explore the relationship between discarded and reused, acquire basic fabrication and design skills and do some intuitive engineering.
