This communications device named after the inventor of the television Philo Farnsworth looks deceivingly simple, but is actually incredibly handy. The primary communications device on the Syfy TV series, the Farnsworth is a two-way audio and video phone that operates on its own secure frequency spectrum. This lets characters remain connected even in basements and in the deepest corners of the woods. It doesn’t lag, operates efficiently and can even hold conference calls. If it came with Android or iOS, the Farnsworth would be a huge seller.
