This unique flashing robot will not only help you learn to solder but will also be the center of attention wherever it is placed! The eyes, center LED and both hand LEDs flash brightly for weeks continuously. Consists of 2 circuit boards and various electronic parts that you solder to the boards. You first solder the non-functional components to learn good soldering techniques, then you progress to the functional LEDs. Simple to build and can be customized to make unlimited variations (you can paint the boards before assembly, pose the arms and eyes, change the appearance of the antenna, etc.)! The 3-1/2" tall x 7/8" wide Learn to Solder Robot uses one 9V battery (not included). Unique design incorporates the battery into the robot to allow it to stand on just about anything (keyboards, monitors, desks, books, etc.). Skill Level 1.
