I’m a hardware developer who focuses on building networks of sensors to collect environmental data, whether indoors, in a city, or in a river or forest.

Wickerbox Electronics

I develop both open and closed source hardware as a freelancer through Wickerbox Electronics, my company, but I prefer to develop in the open whenever I can.

I talked at OpenSourceBridge about Math vs Mathematics and Design from Breadboard to PCB in 2014, and about Getting Started with KiCad in 2015.

Hardware

My Master’s is in Electrical and Computer Engineering with a focus on hardware, so that’s what makes up most of my projects. My early designs were in Eagle but now I work exclusively in KiCad. I develop both standalone boards and attachable boards that fit platforms like Arduino, Raspberry Pi, and Teensy.

Here’s some of what I do:

  • reverse engineer existing boards with no documentation
  • work with the client to figure out requirements
  • order boxes or cases and design the boards to fit
  • research, research, research, and then select components
  • design circuits and create circuit schematics
  • make the board layout by drawing the traces and placing parts
  • order and maintain inventory of boards, stencils, and parts
  • assemble boards by hand soldering, reflow oven, and hot air station
  • test and troubleshoot the boards

I’m available for hire so most of my work is closed source and proprietary, but here’s some of my open source work:
