Solenoid Engine

thingiverse

Work on an intricate project? Consider creating an engine that runs fast but gets too hot for PLA in just 2-5 minutes. Aim to make it with ABS or a better power/solenoid setup for improved heat tolerance. Knowledge of Arduino programming and electronics basics is essential. Check out these video tutorials: http://www.youtube.com/watch?v=SMtnZdwXaJs and http://www.youtube.com/watch?v=kVJHjs5Qt-M for guidance. If you can't find specific supplies, utilize the provided Google SketchUp files to customize your design. Note that printing the arm, elbow, and baseplate is optional if it's just a desk fan for you. The engine functions by shining LED lights on a sensor disk, reflecting light onto a photoresistor, which an Arduino interprets to control solenoid pistons. Two TIP120 transistors and a 6V, 2A power supply are needed, all available at RadioShack. Best of luck with your project!
