I do have recurring donation sites like Patreon, but I no longer post any paywalled content because it's too much trouble and I view it as arbitrary to paywall some material, so use these sites just to donate.
Liberapay (Back from the dead! Use this one if you're new.)
Join LBRY, which is a crypto-based video site via this link and we both get a little of their crypto Monopoly money.
Join Coinbase here and I get $10 in Bitcoin if you eventually buy/sell $100 in cryptocurrency.
Get a VPS with Frantech. This is who I use to host videos.lukesmith.xyz.
I'd recommend Vultr above for noobs and it does come with that extra credit, but Frantech has more expandible plans without bandwidth limitations if you want to do real big-boy stuff.
Donate directly (no fee, via Zelle)
You probably haven't heard of it, but there is a relatively new money transfer system that most banks in the United States maintain called Zelle.
It's really just a protocol for transferring money directly from account to account with just an email, so it works pretty much with the ease of PayPal.
If you have any bank account in the United States, you probably already have Zelle and don't know it.
To use it:
Log on to your online banking for whatever bank you have.
Search for a "transfer money" or "Zelle" section.
(You may have to confirm your email, but "setup" is automatic.)
When asked for a recipient, just put in my email address: firstname.lastname@example.org
Note: If you send a Zelle donation for the podcast with a question or comment, I recommend also sending the question/comment to my email address.
Zelle seems to sometime misplace comments on donations (at least with my bank): I get the money, but if you have a comment it doesn't always display to me.
