We created a smart tissue box that listened along to the show and automatically popped open whenever a touching moment happened in the show. A total of 10 boxes were sent to various social media influencers.<br><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">My Role<\/h3>\n\n\n\n<p class=\"has-medium-font-size\">The primary challenge here was a small budget; to keep engineering costs low, the project utilized all off-the-shelf parts. The box consisted of a Raspberry Pi for audio processing connected to a control system based on a Teensy microcontroller. I designed what was essentially a &#8220;carrier&#8221; PCB to which I soldered a bunch of components and pre-built breakout boards from Adafruit and Sparkfun. The board included a couple different power regulators, a USB-C charge controller for the battery and Raspberry Pi, and other various passives and connectors. I wrote firmware to communicate with the audio-processing frontend and to control various LEDs, the box-opening mechanism and other various features of the box. I also did a lot of creative concepting and mechanical prototyping.<\/p>\n\n\n\n<style type=\"text\/css\" scoped>.rbs_gallery_6a046bb199f03Spinner{\r\n\t\t\t\tmargin: 50px auto;\r\n\t\t\t\twidth:
