Electronic Waste (e-waste) is the fastest growing waste stream in the world. Internet of Things (IoT) devices, now ubiquitous throughout communities globally, are exacerbating e-waste production. Unrepairable design approaches, short lifecycles and ill-defined end of life management all lead to IoT devices being prematurely and improperly disposed of. This paper argues that improved access to knowledge and practical skills is needed if citizens and communities are to successfully embrace a culture of repair and reuse as part of a wider sustainability transition. This paper presents two Serious Games - Re:Play and RepairLand - designed to support and encourage society to develop a stronger culture of repair for smart devices. Applying Research-through-Design and Speculative Design approaches, this paper presents our design decisions and critical reflections that underpin their creation.
