This article documents a study developing a small-scale wave tank, containing an operating wave energy converter (WEC) with active control, the first such demonstration of electronic WEC control at this scale (1/100). The full demonstration system cost just €500, including tank, wavemaker, etc and this article provides full details concerning system construction, specification, testing and performance, as well as aspects related to demonstration appeal. The experimental setup can serve as a valuable resource for introductory research inquiries, catering to both high school and university-level studies. This accessibility opens doors for a broader audience to engage with the potential of this promising technology.
