The aim of Tech Club Joensuu is to foster the hobbies related to sciences and technology in Joensuu and in North Karelia. The Club gathers together the true hobbyists and experts of electronics, programming and design. The activities of the club consists of members' own and shared projects that are processed in the facilities of the club.

The execution of shared projects of TCJ are basically based on recycled use of electronics and other components. On this basis, we can keep both the expenses low and the nature clean.

You do not need to build your projects yourself in your garage! TCJ offers a emphasizing environment for building and members will provide helping hands and suggestions to improve your project.
