Alexa Integration

http://www.jonfenner.com/2016/

Created a previously unavailable feature that connects my personal weather station and Alexa Flash Briefing.

The integrated weather forecast for my location is inaccurate when using Alexa with Amazon Echo Dot. This location has a significant microclimate, and getting an accurate forecast is best done through Weather Underground. This is why I developed my own weather station and linked it to Alexa Flash Briefing.

Robotic Arm for Saffron Harvesting

https://youtu.be/7tOFASmWVNk

I designed, 3D printed, and implemented a dual-robotic arm system for saffron harvesting. It was based on three parallax processors (one for each arm, plus a central controller) and used a JeVois smart video camera for image recognition and correlation.
