NAL IDEAS FR RIGI OM KELVIN® Cuss Remediator Kit O The user loses a coin each time they cuss. The ‘Cuss Work, Fabricate, Assemble! Remediator’ will drop a coin into a container in a series of steps. Keep in mind that Rube Goldberg® made his drawings as a reaction to technology. They were a linear series of complicated steps to perform a simple task. The first lever is pulled by someone after a person cusses, thus activating a second lever, which in turn activates a third lever pulling the magnet away from the steel ball (4th step). The steel ball rolls down the ramp tipping the teeter-totter (5th step) and knocking the coin onto the exposed wires (6th step), which in turn activates the buzzer (7th step) thus vibrating the coin into the cup (8th and last step).

KELVIN® Electronic Troubleshooting Trainers Ideal for middle school students and up. When working within the field of electronics, students should know how to troubleshoot, evaluate, and repair electronic circuitry. The KELVIN® Troubleshooting Trainers are inexpensive and easy to set-up because they require no wiring or soldering. Using troubleshooting and problem-solving procedures, these troubleshooting trainers show students how to find a problem on a PC board and then fix it. The trainers were developed to make teaching troubleshooting fast, easy, and effective – with actual electronic equipment, hardware, and pre-wired circuits. According to the experiments, the teacher inserts a problem into the circuit using DIP switches. By following the circuits and measuring the components, students then isolate the trouble and fix it using problem-solving techniques and by resetting the DIP switches. System concept and student manuals developed by Lou Frenzel. Assembled trainers include: pre-wired PC boards (8-1/2 x 11 in.); 3-ring storage binder; working electronic circuits with DIP switches; student lab manuals with experiments and tests; and teacher’s guide with detailed, documented faults.
