“LinkMenų fabrikas” – a creativity and innovation centre at Vilnius Gediminas Technical University (VGTU) – hosted an international summer school “HEI MAKERS 4.0”. The two-week summer school was for young makers – students from Lithuania, Latvia and Romania. Every country was represented by eight students and tutors came VGTU, Riga Technical University and Politehnica University of Bucharest.

The summer school was organized in the form of hackathon – students had lectures, worked in workshops, received counselling from mentors, and worked in mixed teams to create a prototype of a modern luminaire. The students used the latest technologies in 3D modelling, 3D printing and electronics. At the end of the school, the teams presented their ideas and prototypes in front of commission.    

Four luminaires have been made during the school. A prototype made by the team “FoldEmAll” received the most attention. They created a compact, mobile luminaire, which can be folded into a box and works on an external battery. It is designed for travellers, or when light is needed temporarily. It stood out for its design and compactness, and 3D printed joints have been used in its construction.       


Team “Shinet” made a luminaire with an integrated device for monitoring the levels of CO2. It can be used to monitor indoor air quality at home or in an office. When CO2 levels increase, it starts emitting red light. 

Team “Modularch” made a prototype of a luminaire-arch, which is more suitable for office space or industrial use. It is constructed from separate modules and can be adapted to workstations of various width easily. Its main goal is to illuminate a workstation evenly, without any shade. This team made only a prototype, not the actual size product. 

Team “Build-it” made an assembled luminaire with a rechargeable battery. It is operated with trough a mobile application. 

Summer school “HEI MAKERS 4.0” was organised as a HEI Makers project and was co-funded from Erasmus+ programme of Strategic Partnerships.
