The BBC (No Relation) occasionally makes stuff. Here is where we tell you how we did it.

Barry’s Universal Gronkulator is a Zaurus 6000-based hardware/software combination designed to solve all of your communications needs. It fails, but what the hell.

Did an unexpected rave show up at your house? You’re caught with a pair of blown speakers, a bunch of luvvy-duvvy ecstatic people and no psychedelic lights for them aside from your crusty old laser pointer? Follow these instructions and in twenty minutes you’ll be tripping the night. Fantastic.
Torture and improve your obsolete robot dog.
Make your own flying saucer.
