    Global sunrise/sunset Raspberry Pi art installation

    Reading Time: 3 minutes

    24h Sunrise/Sunset is a digital art installation that displays a live sunset and sunrise happening somewhere in the world with the use of CCTV.

    Artist Dries Depoorter wanted to prove that “CCTV cameras can show something beautiful”, and turned to Raspberry Pi to power this global project.

    Harnessing CCTV

    The arresting visuals are beamed to viewers using two Raspberry Pi 3B+ computers and an Arduino Nano Every that stream internet protocol (IP) cameras with the use of command line media player OMXPlayer.

    Dual Raspberry Pi power

    The two Raspberry Pis communicate with each other using the MQTT protocol — a standard messaging protocol for the Internet of Things (IoT) that’s ideal for connecting remote devices with a small code footprint and minimal network bandwidth.

    One of the Raspberry Pis checks at which location in the world a sunrise or sunset is happening and streams the closest CCTV camera.

    The insides of the sleek display screen…

    Beam me out, Scotty

    The big screens are connected with the I2C protocol to the Arduino, and the Arduino is connected serial with the second Raspberry Pi. Dries also made a custom printed circuit board (PCB) so the build looks cleaner.

    All that hardware is powered by an industrial power supply, just because Dries liked the style of it.

    …and the outside

    Software

    Everything is written in Python 3, and Dries harnessed the Python 3 libraries BeautifulSoup, Sun, Geopy, and Pytz to calculate sunrise and sunset times at specific locations. Google Firebase databases in the cloud help with admin by way of saving timestamps and the IP addresses of the cameras.

    Hardware

    And, lastly, Dries requested a shoutout for his favourite local Raspberry Pi shop Gotron in Ghent.

    87-Year-Old Grandma Uses Microsoft Paint In A Way That Would Probably Surprise Even Its Developers

    Reading Time: 3 minutes

    Some grandmas spend their time in the garden, some knit, but 87-year-old Concha Garcia Zaera enjoys a hobby that’s rather unusually among her friends. She draws. Using only MS Paint. She discovered the program after her children gave her a computer, and she hasn’t looked back ever since.

    “My husband fell ill and I had to take care of him, so I couldn’t go out very often,” Zaera told El Mundo. “I began painting little things: first, a house, the next day I’d add a mountain… Step by step, I was adding details, and in the end, the result was a very pretty thing.”

    “I have no imagination at all, so I get inspiration from the postcards that my husband used to send me or drawings that I find and like.” According to Vanguardia,  Zaera spends about two weeks on one piece and focuses intensely on the details.

    Zaera used to post her masterpieces on Facebook, but one of her granddaughters suggested that she should use Instagram instead. On March 9, she had about 300 followers. As of this post, more than 108,000 people are following the humble artist. “I do not understand very well why my drawings draw so much attention, I think they are very simple things.”
