The Midcoast Mini Maker Faire has already lined up several extraordinary makers, but there is still room for more. There is no fee for exhibitors, and the Maker Faire committee is still seeking presenters with intriguing and inventive ideas; visit midcoastmakerfaire.com for information and inspiration. The event is scheduled for Saturday, Sept. 12.

Makers this year will include Charley Lind with his 3D printer; the Hope Elementary School solar race car project; Stephen Abadessa with both his gassification project and his Arduino models; Meghan Vigeant’s Mini-Memoir recording project; and an annual favorite, the Center for Maine Contemporary Art’s project table.

Lind is an excellent example of the wide-ranging interests and projects of the event’s makers. He will demonstrate a LulzBot 3D printer and offer brief lessons in free 3D drawing software. Attendees will have the opportunity to view a collection of his plastic creations, which will include architectural models, “Minecraft” action figures, a quadcopter and creepy articulated centipedes, all of which were drawn using SketchUp.

The LulzBot is known for its large print volume, open-sourced design and hackability. The LulzBot TAZ 4 creates objects one layer at time using a thin stream of melted ABS plastic filament. Lind is a three-time returning maker, having presented both at the Lewiston-Auburn and Midcoast Mini Maker Faires showing off homemade giant bubbles and handcut foam glider airplanes.

Abadessa also is a returnee. Last year, he brought us his full-scale gassification model, and this year he has offered not only Arduino 101 but also a workshop on making the Arduino” the master of its world.” The Arduino is an inexpensive and easy way for novices and professionals to create devices that interact with their environment using sensors and actuators. Common examples for beginner hobbyists include simple robots, thermostats and motion detectors.
