Check your Mailbox with a fake Apple AirTag

Dakhnod developed FakeTag, a custom firmware for nRF51 chips that is compatible with Apple’s “Find My” ecosystem. With an nRF51 running FakeTag and a vibration sensor, dakhnod monitors if their mailbox has been opened. – GitHub

Building a Smarter Kitty Litter Tray

Andy Bradford‘s cat, Ellie, is hard to pick up and place on a scale. Unfortunately, this means that Ellie is weighed only once a year at the vet. He “wanted to build something that would fit into her life to track her weight automatically, without any intervention”. – Adafruit Blog

ESP32 TikTok Watch

A wearable device to stream TikTok videos to your wrist. – HackADay

LIDAR-based Letterbox Notifier

A mailbox notifier using a LIDAR distance sensor instead of the standard vibration sensor we usually see in these types of projects. – inspectmygadgets

Beehappy, an IoT Beehive

An internet-enabled beehive for beekeepers to track honey quantity, quality, and alerts for if the beehive was tampered with. – instructables

$10 Automated Blinds

An inexpensive automatic blind setup (around $10 per blind) that can be controlled automatically by the open-source Home Assistant software. –HackADay

Expired Certificate Causes German Card Payment Systems Outage

The Verifone H5000 had a security certificate stored on the card reader expire. While this hardware is no longer produced by Verifone, it is still in use across Germany. When building a device that connects to the internet, it’s important to consider how many years the certificates stored on the device are active and provide a way to update them. – HackADay

Custom Web-Based UI for IoT devices with Golioth

Golioth published a blog about designing a custom, web-based UI project, using their firmware and web console. – Adafruit Blog
