Team of new hackers are going to participate in Garage48 hackathon that takes place at the University of Tartu Institute of Physics (W. Ostwaldi 1, Tartu) during the weekend of 2-4th of March 2018. The plan is to build a prototype of a programmable USB device that will help schoolkids to get familiar with Arduino and also educate them about computer security, i.e how a malicious usb stick found lying around in a public place can infect your computer and compromise your data.
