24 alternatives to A tiny solar-powered server only awake during the day
Solar Witch is a little webpage and server which receives and displays messages, so I suppose it's a tiny message board. It's coded in very dubious Arduino C. It's not a 24/7 website. Depending on the state of the battery, the server itself might run all night, but all the messages it receives during the day are deleted at sunset, and the messaging function itself is only active between sunrise and sunset.

Hi HN! I quit my job two years ago to have more time to work on my side projects. The main one is an automated solar concentrator. I've just open-sourced it, it's not perfect nor finished, and I still have a lot of ideas for further development, but I'm interested in knowing what you think of it. There are many applications where concentrated solar power could be a viable environmental and economic solution, I hope this technology will one day be more widely used. Feel free to give any feedback and ask questions.
