[Emily Velasco] has an web supplier that gives sub-par connectivity. As a substitute of repeatedly refreshing a browser tab to check if the community is up, [Emily] determined to create an web standing monitor by embedding indicator lights in a cat cranium…for some purpose.
The electronics are easy, with the entire elements listing consisting of an Arduino Nano 33 IoT system linked to a pair of RGB LEDs and 50 Ohm resistors. The Nano makes an attempt to connect with a identified web site (on this case, the Google touchdown web page) each two seconds and units the LEDs to inexperienced if it succeeds or pink if it fails.
The cat cranium is fortunately a reproduction, 3D printed by one in all [Emily]’s Twitter acquaintances, and the entire mission was housed in a domed safety digital camera enclosure. [Emily] mounts the LEDs into the cranium to create a “mind in a jar” impact.
The supply is accessible on GitHub for these wanting to have a look. We’ve featured web connectivity standing indicators within the type of visitors lights right here earlier than, in addition to varied community standing screens and videoconferencing indicator lights.
