Mini Farnsworth Communicator from Warehouse 13
If you are a fan of show Warehouse 13 you will recognize the Farnsworth. There are many examples of replicas for the Farnsworth, which the characters of the show use to communicate. Many of these replicas take machine shop tools or laser cutters to make. This is not one of those. This miniature version of the Farnsworth is cheap, fairly easy to build, and will in no way pass for the actual device. However, if you are looking for an easy build with fun results, you may like to try it. For detailed instructions, check the Instructable.
