At events at the A32 headquarters you have to bring an ID with you every time: either a student ID, a driver's license, a passport or an identity card. We are there on large sites with companies, secrets, research facilities and security access.
You don't need an ID for the INGenius Space at TU Berlin. We'll just meet there in front of the main building.
You don't need to bring anything else. Materials, tools, etc. are available on site. Feel free to bring things that will help you. Feel free to leave valuables at home or look after them yourself.
