Developing the midterm project
For the physical computing midterm, at first, we started with several ideas that including game, music, art and etc. However, we finally came up with idea for something is more practical, simple and neat. My team, Abhishek, Dalit and I decided to make a device which is an electronic coaster sensing the amount of water in a bottle. And we also designed interface that letting people know about remaining quantity with alarm function showing on computer display.
Prototyping
After deciding the theme, we chose to use large square FSR, LEDs and plywood for making exterior. And with paper, we made our first prototype with paper, which is very similar with our final prototype.
Programming in processing
After our first meeting, I messed around with code in our week 4 lab which is drawing a graph with the sensor value. I made very simple circuit with one LED and large FSR to draw a graph.
After that, I changed some code in processing to show the value that start from the bottom of the canvas to up when pressure increased.
When I drew box shape, I wanted to draw the water level more detail and dynamic. So I tried to make wave on the top of the graph and it was really hard than I thought. After I went through all the trial and error I finally could make graph that waves. Yay!
TELEPATHY!!
Look how similar what we did separately are! At the second meeting, Dalit showed the interface she designed and I showed her what I messed around with processing. They looked pretty similar and we had not even discussed about appearance. We was really excited about it.
