Personal Projects

Prusa i3 (RepRap 3D Printer DIY)

  • Currently building a DIY 3D Printer with my friend Hannah Bryson.
  • Running the print firmware Marlin with RepRap Prusa i3 Printer parts.

Arduino Sensors (Arduino ProMini)

  • Working on a “Mobile sensor station” which will capture readings of Air Quality (PM10 and PM2.5), Temperature and Humidity, and more.
  • Powered via 6V motorcycle battery (charged by solar panel during the day)

    • Graph of Voltage variations over 14 days
    Graph of Voltage variations over Time (Day 0-14)
  • The above graph shows clearly that the system is able to function for at least 10 days without being under AC charge.
    • In the final product, a solar panel will be able to generate some additional power and, using a converter, we will be able to make it last longer (hopefully even a month)
  • Data transmitted to Raspberry Pi and sent back to Cloud for analysis and visualization.
