G'day,
Been hiting the soldering PCB kits latelty so heres something i bought and made:
Its a Magnetic Levitator.
It works by having a magnet below a electromagnet.
the electromagnet repels the magnet and the magnet is attracted to the bolt going through the coil.
You tune the field strength of electromagnet so it is perfectly opposing the magnets field.
There is a power LED (blue) and a Feedback LED (green)
a Hall effect sensor is used for feedback to a comparator and adjusts the pulse to the coil.
a Pot is also in there controlling the feedback.
Here's a video i made (mind the ghetto stand build) lifting a spray pack lid about 15 grams.
i bought the basic kit from here and made it up
Thanks for looking!
