MagneticPropulsion

I little bit of fun and some patience for those who might get this kit for Christmas. Velleman calls it a level 3 difficulty. Stay tuned:)

Soldering to music. Some people find it relaxing and educational. This project is a beginner's surface mount kit with 0805 package resistors and fairly large electrolytic capacitors. The two transistors and two LEDs are smaller but not too difficult. The negative end of the battery holder goes to the bottom of the smiley face as was learned the hard way but good practice desoldering a through hole component. Stay tuned:)

It is very important to see that magnetic resonance is powerful at very low frequency, using small magnets and very LOW VOLTAGE. Stay tuned:)

The smaller previous version of this type of model was pretty quick but puzzling until it was realized the rotating magnet was closer to the magnets on one side than the other. Possibly what is happening here is that the momentum of the rotating magnet is translated from angular to linear when that magnet is attracted to the magnet it is closest to and the "push" is through the axle of the servo to the boat since the side magnets resist rotating. Stay tuned:)

Maybe not the most elegant solution but it seems to work. Stay tuned:)

Picture a seesaw when one end hits the ground and the other end continues upward a little and exerts a force on the center of the seesaw or the fulcrum if you will. That is just like the free to turn magnets or compass striking the stick at one end and pushing the boat through the axle. Next consider that a magnet rotated around its center of magnetic torque and center of mass cannot exert a force in any direction but only a turning torque. That corresponds to the magnets on the servo which are not capable of having a net force on the axle of the servo and hence no affect on the boat. Now combine the two and the boat gets a net force opposite the direction that the end of the compass hitting the stick. The boat goes west! Stay tuned:)
