Well, if you found this, you are probably a fan of Warehouse 13
. 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 Instructable is for a miniature version of the Farnsworth. It 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.
You can see it in action in the video above.
