Hi!
I would like to know what are bi-directional capacitors? How do they differ from other caps?

i mean the two 10μF electrolytic capacitors being used in the attached imageYou mean bipolar caps, the one you wear to disguise the OCD?
are the two 10μF electrolytic capacitors used in this circuit the ordinary polarized electrolytic capacitors you refer to? Is the "bi-directional" (quoted for internet source) capacitor the non polarized electrolytic capacitor you refer to?Digikey sells Japanese non-polarized electrolytic capacitors.
You can connect two ordinary polarized electrolytic capacitors back-to-back (negative wire connected to negative wire) to make your own non-polarized electrolytic capacitor.
They also make some very large ceramic caps these days if the working voltages are 35V or less. They are non polar and have better frequency response than electrolytics and are cheaper than film caps.You can buy a pretty big and pretty expensive 10uF film capacitor that is non-polar if you want.
