As part of this year's CHRISTMAS LECTURES, we want to showcase the creativity and ingenuity of the ‘’ will show how the spark of your imagination and some twenty first century tinkering can change the world. But, we would love to showcase the creativity and ingenuity of the maker community too. Are you interested in getting involved? We want to see your projects. Have you hacked yourself a self-timing dog feeder, modified your house’s light switches, or reinvented your phone? No project is too big or too small – submit yours now! As lightbulbs, motors and phones are the lectures' key objects, hacks based around these are particularly welcome. http://www.hackgallery.org/submit The CHRISTMAS LECTURES have been running for over 180 years, and will be broadcast on the BBC in December before going up on the Ri Channel for everyone to watch for free. We won’t be able to feature every project and idea in the lectures themselves, but hopefully on this site we’ll build up a gallery of inventive and exciting hacks that will inspire everyone to have a go themselves.
