Beginner Electronics Project: Simple Oscillator with 555 Timer and Speaker in Astable Mode EVLOG #7

I have grand ideas of making a fully operational VCO oscillator and using 555 Timers as the primary driver. Is that practical? I don't know, but here is a video of testing it out.

Let me know what you think. Any comments are always welcome as I'm new to this level of electronics and can always use more advice. Thank you!
