Easterhegg 2017-04-15 - - - - - - - - - - - Our approach* wrote experimental capture program* evaluated and bought hw components* dry run* designed cabinet* built cabinet* added LED effects, flash etc. - What is a photo booth?* Name origin are actual BOOTHs (train station)* Japan: Purikura (プリクラ) machines since 1995* automatic device that takes pictures of you* camera with self-timer or webcam* usually equipped with a preview screen* sometimes equipped with a printer* sometimes equipped with social media sharing* usually saves the photos* sometimes equipped with funny props* typical use cases: weddings, birthday parties, corporate events, fairs - Motivationwhy would you need one* it's fun to use* you can make money with it(professional photographerscharge up to 1500€ for a day)why would you wanna build one by yourself* it's fun to build* you can make money with it* you learn a lot* multi-disciplinary project* is ideal for hacker/maker space teamwork - Easterhegg 2017-04-15 + +
