Podcasts can be incredibly enjoyable, both for the person listening and the person recording. I've been on both ends of the equation many times and both are enjoyable.
All you really need to record your own podcast is a computer and a microphone. You can even record one using just your smartphone if it's a simple solo show without much editing.
You can host your podcast for free using BuzzSprout as you're getting started, then upgrade to other plans if your podcast becomes popular. Of course, when it becomes popular, you can actually start making money with it.
Making money from a podcast is a bit tricky, but once you start raising an audience on your own, you can look into the possibility of joining a podcast network, which often serves as a collective for finding and negotiating with advertisers for the purposes of raising money.
Not only that, podcasting is a great way to get involved with the online community of whatever topic you're into.
