Summary

This chapter focused on iterations of Message Bag, alongside putting into practice several of the skills that we’ve been working on throughout the book. We looked at a template for designs, how to start our projects, and whether we want to focus primarily on the technology we have to skill up or whether we want to focus on a certain context. We discussed our observations when using the proof-of-concept prototype that we created on a breadboard and the ways that this could be improved. This gave us the content to make iterations and finish off the wearable design to create an integration prototype. We soldered and sewed it into place too, completing the project nicely.

After completing Message Bag, we learned that all prototypes have opportunities for improvement. Often, we can swap out a component for a smaller one, or something with more functionality. In this chapter, we looked at adding memory, used to store our tag scanning, and adding IoT capabilities so we...
