I have done some simple magnetic levitation system,
based on LED-photodiode pair,electromagnet,and feedback/amplifier
circuit.
Contains
1 LED
1 photodiode
2 capacitors
2 resistors
2 variable resistors
4 transistors.
and one electromagnet.
(but not very stable because 1:circuit is simple ,2: my photodiode is
too small)
It's senses position of thing by photodiode,and control current of
magnete by mix of signal from photodiode and time-derivative of signal.
I make it fly,and now i'd like to compare my circuit with other
circuits.Searching by Google,i found only one circuit,and many
microprocessor-based levitation systems.
Thanks for any circuts/links/etc,
Regards,
Dmytry Lavrov.
p.s.
i know,it's not about this NG,but i don't know where to put it..
sci.electronics completely spammed.
I will prepare my circuit for web...
