With the first full version assembled, this week was its first real showdown. We brought every piece together and put the prototype through its first proper trial, watching how the sensors, firmware, and enclosure held up as one wearable rather than a bench of loose parts. It was equal parts exciting and revealing: the things that worked gave us confidence, and the rough edges told us exactly what still needed attention. We spent the rest of the week finalising the prototype, tightening the build and ironing out the issues the showdown had surfaced.
