Trying to build an open-source flow battery using appropriate technology design principles to enable decentralized energy systems! Right now working on a “dev kit” of sorts and plan to run some workshops with it for students and interested folks. Then continue to scale the system up as it makes sense, ideally to the multiple kW/kWh scale. My fantasy is using such systems to enable renewably-powered housing communities and small industry.
If you want to follow along/contribute, we set up an open collective here: https://opencollective.com/fbrc#category-ABOUT which has links to our personal blogs/repos (I am also more active on mastodon at @kirk@social.coop)
Yunohost for me as well. My only prior self-hosting experience was installing Nextcloudpi images for raspberry pi, and it was a similar experience once I knew how to forward ports on my router etc.
It even automatically set up an email server and XMPP server by default. I don’t use XMPP and hadn’t planned on hosting my own email, but, here I am. Installing apps feels like using a mobile app store. Hosting nextcloud, freshRSS, static blog, WordPress, listmonk, wallabag, other stuff on a small ARM SBC, with plenty of resources left.
I don’t even really know how it works 😅 but I contribute on Liberapay and try to keep good backups and only install well-rated apps.
