Although building such a demonstrator yourself can appear overwhelming, we argue how building your own improves your teaching of embedded software. We report on how we have achieved these improvements with a development process that lets our teaching co-evolve with our own demonstrator, share our main lessons learned, and invite educators to discuss remaining challenges.engmodel railway demonstratorevolutionary developmentembedded softwareconferenceobject10.18420/seuh2024_06
