Charles Lohr spoke with us about $5 WiFi (ESP8266), hacking as a hobby, arcade games, and music visualization.

Updated 06/02/2015: A listener pointed out that the Arduino IDE can program the ESP8266, probably an easier setup than Charles' original article. Also, the Linker post for this show is about getting started with BLE.

Follow Charles on YouTube (or say hello on Google+ and Hackaday.io). To get you started, here are Elecia's favorites:

• High Res Wifi Signal Mapping (ESP8266) 
• ColorChord 2
• Wifi Cup (ESP8266)

• Charles' Hackaday write up (and github repository)
• Espressif site
• Electrodragon, Adafruit, and Sparkfun have modules
