We could add some of these to an RSS feed post bot for Lemmy that I am experimenting with.

Edit: we have an RSS feed post bot now. Time to look into adding some of these feeds. I already added Low-tech Magazine to the /c/technology community.

am not sure if entirely fitting the criteria but i quite enjoy hackaday.com for all the repairing tech n diy stuff they have

I've been wanting to move away from Substack for a while due to the politics involved with their founders, but there is an RSS feed for posts: https://anarchosolarpunk.substack.com/feed Hopefully, I can get some time to move my posts to a self-hosted (and solar-powered) server.

While they aren't blogs, I think Solarpunk Now! and Solarpunk Presents are two great podcasts: https://www.solarpunkcast.net/ https://shows.acast.com/solarpunk-presents
