Hello everyone! If you go back to my week 1 website you could see that I explained my final project with some early stage diagrams. The goal was to communicate the idea more than the actual object. I started sketching some ideas and surfing the web on how could I get it done. After seeing some landscape solar led lamps I knew I had to go that way.

In order to hack or evolve the landscape solar light I had to understand the elements. The system is pretty simple as it only needed a solar panel connected to a small battery and a led bulb. In order to accomplish my idea of identifying a pedestrian, I had to add a motion sense device. After some research, I found about the HC-SR04 sensor that uses Arduino. This system can identify how far an obstacle is, another cool thing about this gadget is that it can make noise!!

After the sketch phase, like in architecture I had to start drawing with real units. For the 3D modeling I used Sketch-Up and Adobe Illustrator for creating those vector diagrams. The whole concept of Sketch-up is to “draw and pull”.

This is the early stage on how my small motion sense solar led light would look like! I have no idea how to connect every hardware, this is the first time I'm dealing with electronic part so I'm assuming EVERYTHING.

The whole system seems pretty simple but I needed to solve the distance sensor within the form of the object. At first I was thinking of a cube or similar but since the pedestrian act as a vector I needed a form that could have sort of 45 degrees. So far the pyramid solve this problem as it can detect any obstacle in both ways of the street.

This geometry seems to respond to my requirements but I believe it can change as long as I have a triangular base where the sensor and solar panel are.
