Design Evolution

This project has certainly evolved over the course of this project and there is quite a few story's I could tell you. Rather than attempt to describe with multiple project logs detailing each step of the design process and the decision tree that has led to the design today, I dug around in a few of my boxes and found a pile of old parts and selected a few to create visual demonstration in the form of a timeline.

Some might look very similar and some look very different but it's all progress for this project.

You my notice the larger PCB at the top middle, these were the first multi touch sense PWA that I designed and made. They were for the first prototypes of the Touch modules (The Touch-D came from the evolution from using multitouch PWA's to touch screen displays.)

To give you some perspective:

Take the design evolution of the Touch Module and Scroll Module from the first prototype (A blast from the past for me) to the second prototype. I would say these two modules has had at least 50 revisions made over it's life cycle. The revisions made were all positives to improve: Size, Feel, Functionality, Manufacturability and Reliability. These prototype stages also covered major design changes like for example how the module would change shape and the incursion of the panel system. I'm sure this design will continue to grow and mature when the design hits the production stage and I certainly look forward to it.
