Manolis Nikiforakis and his team (Dimitris Karagiannis and Thanasis Daglis) set out to create a multiplayer reactive game, using mostly Arduinos and Particle (Spark) Cores, where the losers’ money would automatically be donated to charity! Well, that was the main idea, but -unfortunately- time was not enough for them to fully implement it during the 24-hour duration of BattleHack. Nevertheless, Manolis (a seasoned researcher and developer with 12+ years of experience), confessed to us that he loves taking part in hackathons… just for the fun of it. And, surely enough, we also talked a lot about the opportunities arising all the time, as technology evolves, for example in the relatively new field of IoT.
