2x Solar Levitator Motors
Using the SS1CC circuit from sMartcreations2010, these are my first two levitator type projects. Transistors are B5654A PNP and D471A NPN, 2x1000uF caps instead of the single 1000uF in the original circuit. I found that increasing the capacitor sizing made the circuit less finicky with these coils used. The coils make a chirping noise when near to a magnet. The first levitator shown, is a build from scratch, using ceramic magnets. The two rotor ceramic magnets sit on a piece of carbon fiber (normally used as brace bars on micro R/C aircraft) and has a small neodymium in the middle, taken from an old 6mm coreless motor. The propeller comes from the tail motor of a Picoo-Z type R/C helicopter…quite a lot of micro R/C components on the build ! The power coil is a 400 winds tiny thing, using relay wire and wound on a piece of ferrite. I was pleasantly surprised at the distance achievable between the coil and neo magnet. The second levitator is based on a non powered design from Amazon.com. While only costing $7.99, they haven’t had very good reviews and mainly because of their willingness to bounce around. Still, when carefully set up on a flat surface, they do spin well. I put 4x small neo’s around the middle, arranged N/S/N/S and underneath is a small coil from a relay or solenoid. It audibly clicks along and the blue LED flashes with each coil collapse. That one ran all evening ‘on test’ when built the other day and adding the blue LED today hasn’t affected rotation …
