Solar pendulum

Hi there,

Nice project. Just a couple of questions about this circuit. I'm new to electronics and like to try understand what I'm building.

Is this essentially an astable multivibrator configuration ?

I'm also wondering what the extra components you have wired in the photo of the build. I see 3 possibly 4 capacitors. Are they just wired to give the capacitance in the circuit ?

Thanks
Marc
