Looking at the 3 cited projects, I don't see anything that precludes Github Pages or similar. At first I thought they were dynamic SaaS services and wondered why he'd run those from his dorm. But as best I can tell they're not - they are landing pages and docs for open source projects (cool looking ones, btw.) Slap those up on a static site somewhere for free or really really cheap.
Glitch.com might be another option - static websites are always-on and free. If you do really need hosting, 8$/mo for 5 linux containers is a nice option. Personally that seems cheaper in the long run than running a bunch of stuff on your own hardware, network, power. Maybe even add a "buy me a coffee" badge or hit up your mailing lists for help covering hosting costs.
