While the guys in Production are busy packing the retail packs, I can’t help browsing Maker Faire’s Blog to see which incredible inventions we should expect to find at the Maker Faire this weekend...

Another Maker Faire Attraction: Etch A SketchJust Add Sharks, are set to bring their ingenious Laser Etch A Sketch to Maker Faire UK. The prolific Midlands makers have combined a shared love of lasers, Arduinos and nostalgic toys to create an effortlessly cool gadget, which we all can’t wait to see demonstrated! The Laser Etch A Sketch controller is an incredibly fun hack that was built to celebrate International Arduino Day. How does it all work? Two rotary encoders housed inside Etch A Sketch-style wooden knobs are connected to an Arduino Pro Mini. When patched into the existing wiring of a Blacknose A3 laser cutter, this interface can be used to bypass the machine’s on-board controller. As the Arduino detects the knobs being turned, it sends a signal which fires the laser. X and Y axis information is simultaneously passed on to the stepper drivers, controlling the position of the laser beam. Two power settings are available: the first will mark a material and the second more powerful mode allows for cutting. See the Laser Etch A Sketch in action: The Etch A Sketch mod is perfect for cutting straight lines without the need for extra programming, for instance, but it is worth mentioning that the laser cutting can still function as normal – this awesome invention is a great little novelty controller. The controller itself is custom built from six layers of lasered plywood and stained with mahogany wood dye to give a red finish. The final, wonderfully lo-fi touch is the screen, fashioned from a layer of baking paper to give the look of frosted plastic. So… will we be seeing you there?
