Adafruit customer Clafrieda (Christopher) turned his son Charles into an astronaut for Halloween. He started with an astronaut costume and helmet from the store, and Christopher dressed it up using electronics from Adafruit, including an Arduino. Christopher says:
Started with an astronaut costume and helmet I bought on Amazon and printed a bunch of 3d parts (PLA and Ninjaflex) to make the chest pack, headlamps, and wrist computer. I had most of the components except the sound board and touch screen. Fun project.
Added lights (Neopixels) to the inside of the helmet and two on the outside with some salvaged flash light parts. The chest pack houses an arduino and adafruit sound board/speakers to play com audio downloaded from nasa. In addition, there is an arduino powered wrist computer with a touch screen to control the lights and coms.
