During the product development stages we produce several rounds of prototypes. We often start with simple block models to evaluate ergonomics and size. Next can be partially functional electronic prototyping to evaluate the best cost/performance of certain components. We end with complete looks-like-works-like working prototypes, for client approval. For reasons of speed and IP protection, we do most of our prototyping in-house, the housings 3D printed and the circuits often hand soldered by our nifty technicians.
