Because I manually download videos to watch on the bus or train (thanks Grayjay & NewPipe), most of my subscriptions are for long-form, often listenable content:

Bold channels are most underrated imo

If you really want a prebuilt one, of course.

I was wondering about OP’s soft-eject floppy drive. Seems quite retrofuturistic.

Yes, get yourself eclipse glasses, a pinhole projector, a floppy disk, digital camera or whatever allows you to observe the eclipse safely – no phenomenon is worth risking your eyesight over. However, the consensus is that you can watch the sun flares without protection during totality. The totality lasted 0 to 4 minutes depending on your location.

…and ignore one of the coolest things there is to see on the sky

A solar or lunar eclipse?
