Self Directed Learning

Continuing Education Projects

  • Co-founded "electronics club" with a colleague. Met weekly for two years to teach ourselves the basics of electronics in order to expand our skillset. Started with zero knowledge.
  • Completed many tutorial projects on electronics fundamentals based on Forrest Mimm's book "getting started in electronics" and completing the circuit classic kit. 
  • Completed many experiments and tutorials for Arduino, Circuit Playground, and an introductory course on Raspberry Pi
  • Designed, manufactured and successfully assembled a custom PCB using EasyEDA based on a schematic found in a textbook that was first breadboarded, and then perf-boarded.
  • Current project is to create a solar powered mood lamp. To date have sourced and assembled a "sunny buddy" charge controller, sourced and soldered together solar panels, lipo battery pack, buck-boost converter, and sparkfun lumenati 8-pack LED ring. All existing components successfully assembled and tested. Working on integration and testing!
  • Also taken continuing education courses on Python. Completed "An Introduction to Interactive Programming in Python" offered through Coursera/Rice University.
