Weekly Update- It's Been Too Long

A lot has gone on this past week since our last update. This week was spent on the completion of the mechanical as well as electrical design. On Thursday (4/10), the accelerometer got hooked up to the Arduino and had outputted live data. We have also started coding in order for the Arduino to read data from the accelerometer. The mechanical design was finalized that Saturday (4/13). Most of the material and equipment needed was obtained as well such as CO2 cartridges, 1/4" tubing, breadboard, tube coupler, and ideal tube fastener. These parts were partially assembled. Coding for recognizing free fall as well as sudden change in acceleration started Sunday (4/14). But it didn’t go as smoothly as we wanted it to. After about a few hours, the accelerometer’s output data became corrupted. We were bound to encounter technical difficulties during this process.

Today we started the implementation of LEDs to help detect accelerometer data. The design part which twists the valve from the motor was also drawn in CAD.

Here are some photos of this week’s progress.
