Versatile realistic 3d simulation: No other realistic circuit simulator out there focuses on the hands-on experience of circuit assembly, while offering realistic gesture motifs for soldering techniques. Pro-tip: hold the stylus longer on the joint-solder unit and watch it spread! Be sure to move the solder so that it is touching the joint; drag with your finger - the motion is like that of stiff solder wire. Another tip: the sponge gets dirty when you clean the soldering iron too much! Yet Another tip: try tapping around for loose circuit parts in Assembly Mode to make sure everything is in the right place. Educational and Technically Innovative: pushes the limits of what mobile can do S Pen represents a real tool, that is traditionally both expensive and dangerous Audience: Students and hobbyists – both with budgets to purchase educational tools Re-usability: The app backbone is a basic circuit simulation engine, that students can use to learn a whole host of other circuit assembly hands-on techniques. The barebones of a platform have been designed for this competition. Experience: The audience seeks realistic hands-on assembly of circuits! Uniqueness: This is the first app to feature 3D circuit creation simulation, using a stylus as a soldering iron.
