This is the most advanced kit which introduces elementary control technology in the form of switching mechanisms such as reed and pressure switches, trip switches and double pole switches all of which are constructed from simple TechCard materials. The kit includes photocopiable work sheets, teachers notes and enough TechCard and mechanical components to build ten exciting models.
Control-It Kit models include an electric loco, a hoist, a cable car, a bumper car, a table top flyer, a pressure sensitive alarm, a movement detector and a pneumatically powered grabber arm and loading shovel.
The basis of the TechCard system is a set of pre-cut, scored and punched card components that are simply folded and glued to form an infinitely variable range of girders, beams and bases. The overall dimensions and grid of pre-punched holes make accurate model building remarkably easy, making TechCard an ideal system for developing model making skills, 'design and make' and prototyping.
The TechCard structural components are made from 100% recycled material making it a uniquely affordable and environmentally responsible building system. TechCard components are easily customized by cutting and scoring with scissors or a craft knife and glued together with ordinary PVA glue which is safe and quick to use. The TechCard structural elements are complemented by a complete range of mechanical components including wheels, axles, pulleys and gears as well as pneumatic systems, propellers and much more.
