The Great Internet Migratory Box Of Electronics Junk, known as TGIMBOEJ, is a community project that turns sharing electronic components into a traveling, collaborative experience. Described as a progressive lending library, each box moves from participant to participant, arriving filled with a changing assortment of components that may be useful, unusual, or simply intriguing. Members can look through the contents, keep items they can use, and contribute components from their own collections before passing the box along.

The project combines the spirit of peer-to-peer sharing with the discovery of a flea market, encouraging curiosity, reuse, and participation in electronics and do-it-yourself projects. TGIMBOEJ provides online resources to help people take part, including guidance on joining or starting a box, box tracking, requests, and frequently asked questions. Its wiki also supports community contributions, with pages that participants can create and edit through a registered account.

TGIMBOEJ is sponsored by Evil Mad Science LLC, a supplier of DIY and open-source hardware
