The Townhall web application (beta) is a simple input form that allows anyone to submit a question. 

 

Technical:

Each question is posted to a Firebase instance through the user-facing Angular app. For each new question, a webpage constantly running on a smartphone hidden inside of the pedestal converts the text to speech via tts-api.com, then simply plays the returned MP3 through the megaphones line-in.

The megaphone is supported by a custom designed prop printed on the UP 3D printer as detailed below, then modified by hand with a drill press
