I took an electronics course nearly 20 years ago now (hard to believe it's been that long) and although I wired up several timers back in the day, it took me an embarrassing number of hours spread over 3 days to re-learn. Part of the problem is that the capacitors are scavenged from an old stereo amp and I wasn't sure if I'd maybe fried them with the heat of desoldering, so it was hell to troubleshoot, since I don't have the tools to test capacitors (my multimeter is pretty much the cheapest one you can get :P). Anyways, I'm maybe way too excited by my success, but I thought I would share anyways!

So cool! I haven’t fiddled with electronics in a long time I feel like I got a bit overwhelmed with YouTube videos- any suggestions for tutorials/lessons?

Seeing as the first few "howtos" I tried didn't get me anywhere for 2 days, I guess even though I didn't actually read the whole thing, but just skimmed over it and swiped the wiring diagram, https://www.jameco.com/Jameco/workshop/TechTip/555-timer-tutorial.html was the one that finally got me there, along with the EveryCircuit app on my tablet, which helped me troubleshoot having gotten my resistor values backwards.

Congrats! I've been wanting to get back into small electronics/arduino stuff. I've got a little breadboard kit, I've never scavenged parts. But that sounds pretty awesome.

I had gotten some desolder wick when I decided to take a stab at fixing my 2nd monitor by replacing the capacitors, and seeing as there's a lot more of it than is needed to desolder 6 caps, I decided I could make use of it for liberating parts from an ancient stereo amp. It was only after being empowered by having the wick that I realized you probably don't really need it for just liberating parts, but it does come in useful at times to get the component legs clean enough to fit into the tiny breadboard sockets.

What does it do?

It provides a pulsed signal at a certain frequency depending on what resistors and capacitors you set it up with. You can use that signal for any circuits that require a "clock," or in this case, just run a single LED which will blinks at said frequency.

Eh! Grats! It's always exciting when electronics work out how you want them to. My first attempts years ago with FSRs activating LEDs was a nightmare, but getting it right felt so good.
Good luck on recalling the rest! It will come back to you.
I have literally no idea what this means but it clearly makes you excited, so yay!
Not trying to be sarcastic, just confused but still excited.
