Genius Electronics Where Learning and Fun Become One!    Complete kit with all parts, convenient storage tube and instruction manual. The VS-1 kit is full of fun features! Illustrated manual introduces basic circuit theory as it builds understanding and competency in building circuits using schematic diagrams. Sensors detect the real world and make the circuits fun and interesting! Included manual is printed in black-and-white. Color is available at additional cost (call for pricing). Durable and attractive storage tube meets USPS regulations and can be mailed with no additional packaging (great for mailing as gifts or samples!). Basic circuit theory is developed with the use of the intuitive classic "water circuit" analogy. Jumper clip connectors and well-illustrated manual illustrations make building circuits simple, fast and easy to understand. Circuit diagrams use a unique blend of pictorial and schematic style to maximize learning. Transistor circuits include amplifier and "Magic Night Light."
