Thinking Man

This project was featured in the Feb/March 2016 issue of Make: magazine and on the Make: website! The Make website has an awesome build video.

When you turn it on, Thinking Man grabs a random post title from and prints it out.

When you first plug it in or press the button on the back of the neck, a post is downloaded and printed.

The thermal printer came from Sparkfun.

The guts include an Arduino Mega, and an ESP8266-based wifi module that I have hooked up to a 3.3v voltage regulator and logic level converter.  This photo shows power coming from a bench power supply and a buck converter, but it can be powered by a 9v 2a wall wart.
