@strobosk it seems to me like it would eventually reach a stable frequency where the object bobs at the right speed to levitate below the laser line... I don't see why you need the micro unless you want distance control.
@ossumguywill for levitation you must find correct coefficients P (proportional) and D (differential). So that why you need a microcontroller. For reading A/D channel and than calculation of equation.
I wonder if you can smooth it with PWM and some formulas for predicting its location when in freefall (taking into account the magnetic strength dropoff)

that's fantastic! great job!

could'nt you just use the light barrier to turn off a transistor and let it run free?

hehe, it's not that easy :)

So is the coil just on/off or can it sense the distance to the object and adjust accordingly?
hummesse 3 years ago
The coil is controlled with pwm using PD (proportional diferential) regulator. The distance is measured with a/d converter on light sensor.

May I ask how many volts your running in that coil?

20V

How does that work? Is the coil turned off while the object is between the light barrier?
Thx if you could explain.

Hi, yes, the coil is turned off while the object is between the light barrier and turned on when it's not between the light barrier.
