The effect of the lasers and smoke make an impressive magic chalice! This project tip was sent in by Matt. Via The Blogger Brothers:
It’s a small smoke generator controlled by Alexa – that allows you to evoke the chalice of fire one might imagine being part of Harry Potter’s world. The smoke is illuminated by high-ish powered lasers, and the whole thing is controlled with an ESP8266 and an Alexa Skill.
How does it work?
It generates smoke using Nichrome Wire, and propylene glycol and the whole thing runs as an Arduino Script, powered by a high amperage 5V source.
How does Alexa fit in?
Alexa sees the ESP8266 as an outlet it can automate. That outlet is then automated using Alexa Routines! So now when I say: “Alexa! Wizards Fire” she responds, “Behold, the fire of the ancients.”… and then I cackle for about 2 minutes.
