I built an Alexa Skill, and got it published.
How I Learned Alexa Skill Kit and Why I Picked it Up Again
I learned about Alexa Skill Kit at Hack Arizona 2017, and built an incredibly complicated 520bus skill to query departure times of Sun Tran buses and Sun Link modern streetcar. I didn't win a prize, and quickly forgot about that.
A few months later, a tweet caught my attention: publish a skill, get an Echo Dot & Alexa dev swag. I always wanted to own a hardware device that integrates with Alexa. I considered the "practically free" Dash Wand, but gave up when I found out it is powered by batteries. I couldn't afford to buy an Echo, because I already spent all my money on those ESP8266 toys. However, I'm not going to miss a FREE Echo Dot.
