Replied to bookmark Site.js by Aaron Davis

Small Technology Foundation has created a simple library for setting up your own site quickly and easily on the web. This is discussed further in a presentation by Aral Balkan at Creative Mornings Istanbul on 26 June, 2020.

I spend a couple of hours last night trying to set up Site.js on a Raspberry pi, I got it working locally, but fell at the https cert and I think my firewall.

Looks fascinating as does Small Technology Foundation Personal Web Prototype-01: a mobile personal web server which is a portable server you can carry about in your pocket. Put together from a pi and some bits I wish I could afford to buy the bits for that. Reminds me a wee bit of the piratebox.

After seeing @adders on posting some timelapse I though I might have another go. My first thought was to just use the feature built into phone. I then though to repurpose a raspberry pi. This lead to the discovery that two of my PIs were at school leaving only one at home with a camera. This we zero had dome sterling service taking over 1 million pictures of the sky and stitching them into 122918 gifs and posting them to tumblr. I decommissioned that when tumblr started mistaking these for unsuitable photos.

My first idea were just write a simple bash script that would take a pic and copy it to my mac. I’ve done that before, just need to timestamp the image names. Then I found RPi-Cam-Web-Interface. This is really cool. It turns your pi into a camera and a webserver where you can control the camera and download the photos.

I am fairly used to setting up a headless pi and getting on my WiFi now. So the next step was just to follow all the instructions from the RPi-Cam-Web-Interface page. The usual fairly incomprehensible stuff in the terminal ensued. All worked fine though.

I then downloaded the folder full of images onto my mack and stitched them together with ffmpeg.

ffmpeg is a really complex beast, I think this worked ok:

make a list of the files with

for f in *.jpg; do echo "file '$f'" >> mylist.txt; done

then stitch them together:

ffmpeg -r 10 -f concat -i mylist.txt -c:v libx264 -pix_fmt yuv420p out.mp4

I messed about quite a bit, resizing the images before starting made for a smaller move and finally I

ffmpeg -i -vf scale=720:-2 outscaled.mp4

To make an even smaller version.

I am now on the look out for more interesting weather or a good sunset.

Snail Habitats For Mrs. Nations Class

These are student created snail habitats. Each habitat has a Raspberry Pi computer with a mini camera attached to it, which is programmed to take a snapshot photo every hour. This will allow students to see where the snails are hanging out the most and improve their habitats over time.

This looks like a great project. I wish we has seen it when we had our mud snails in class.

I don’t think we could have used Raspberry PIs on the school network but I am sure this could have been adapted to see the photos locally in the way we use our @naturewatch camera.

It also reminds me of my Raspberry Pi Gif Cam
