A deep dive into the process of designing and implementing a fully custom-built wearable video screen, which was used on a 50-date international arena concert tour by a well-known musical artist in 2025 and 2026. Details of all aspects will be explored, from initial concept design with the artist's creative and tour production teams, technical electronic and mechanical aspects, integration of the electronics into the costume, as well as the practicalities of building reliable & robust hardware on a very short timescale. And of course the safety aspects of making a body-worn system capable of using over 250 watts of power. This was a commercial project, and is planned to be a joint presentation by myself (freelance electronics consultant) for the technical aspects, and my client (design studio) talking about production liaison, logistics and final hardware integration (sewing & wiring!).
