This is a useful guide. I remember Oliver Quinlan, a guest on Radio EDUtalk talking about the eloquence of the command line compared to pointing and grunting.
I enjoy using the command line, often with Raspberry PIs, but it is easy to miss some of the basics which this guide covers well.
Just set up my pi as an AFP server using How to Setup a Raspberry Pi AFP Server – Pi My Life Up pretty straightforward. Quite please with myself. I wonder if I could have a pi with a big SSD on it. Seems you can set the pi up as a Time Machine. I didn’t manage to mount my home folder but can get /var/www/html to work which might be useful.
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 micro.blog 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 mac 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 out.mp -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
Art installation and social commentary from maker Dries Depoorter, with a Pi, and Arduino, and a nicely finished enclosure.
Quick Fix — a vending machine for likes and followers
Quick Fix is a vending machine (and art installation) that sells social media likes and followers. Drop in a coin, enter your social media account name, and an army of fake accounts will like or follow you
sounds like fun on several levels.
The 100,000 gif on Ski Pi was published yesterday. These are gifs create by one of my PIs which are automatically uploaded to tumblr every 15 minutes.
I think it might be time to repurpose that pi or switch to video or something else. The process was more fascinating that the result. I need a better view perhaps.
