[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 simple, with the whole components checklist consisting of an Arduino Nano 33 IoT gadget related to a pair of RGB LEDs and 50 Ohm resistors. The Nano makes an attempt to hook up with a recognized web site (on this case, the Google touchdown web page) each two seconds and units the LEDs to inexperienced if it succeeds or purple if it fails.
The cat cranium is fortunately a duplicate, 3D printed by considered one of [Emily]’s Twitter acquaintances, and the entire undertaking 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 obtainable on GitHub for these wanting to have a look. We’ve featured web connectivity standing indicators within the type of site visitors lights right here earlier than, in addition to numerous community standing displays and videoconferencing indicator lights.
