Some of you may already have seen solar.lowtechmagazine.com/2018 . It is a re-design of Low-Tech Magazine that I did together with Marie Otsuka and Lauren Campbell. After a few months of working on it I'm happy its out in public, survived the attention and creating discussions!

@rra Are you someone we can ask technical questions about the project, and if so do you mind if I do? :)

@rra What I'd love to see is some idea of how much the current draw from the hardware you use for the site device varies over time.

I was curious if we could use a similar technique (in my region, the wind is often above 10mph so we might consider homemade microturbines as well as solar) for running a custom, minimal ActivityPub server, so that people could have a purely off-grid mastodon instance.

@rra I'm trying to work out what a slightly more sophisticated processor load would look like in this case.

Hi @endomain I've written some technical documentation about the project over at homebrewserver.club/low-tech-w

The power statistics of the server are actually published here: solar.lowtechmagazine.com/api/

From what I've experienced running in hosting the post.lurk.org mastodon instance, you'd need a much beefier machine and probably would also need to attach an external hard drive. Pleroma is actually designed to be run from RaspberryPi-like machine so perhaps you'd like to start there?

@rra Thank you! I'm reading this now.

As for the available power; I'm woking on writing an ActivityPub implementation compatible with Mastodon's rules that does not have any interface and uses tricks I know in my capacity as a distributed systems engineer to reduce I/O loads.

I only just learned of Solid, but it's in a similar design where your workstation terminal would provide the UX independently.

@rra It also occurs to me that with a very small javascript library, you could let client browsers opt into become rich clients for your site via Service Workers and the Cache library (https://developer.mozilla.org/en-US/docs/Web/API/Cache).

Most modern web browsers support Cache & SW, and they represent a considerable power savings in mobile contexts for clients. I had never considered it before, but I suppose it'll amortize the cost of sending the JS and result in server power savings quickly.
