Person Wearing Haptic Headband With Vibration Motors This Arduino UNO Q Headband Uses 13 Vibration Motors for Screen-Free Awareness Through Haptic Feedback

Maker pasquale887 has developed HaloSense V1, a wearable haptic headband that helps users sense the direction of people and objects through vibrations instead of looking at a screen. The headband has 13 small vibration motors arranged around the forehead. When a person or target is detected in a particular direction, the motor in the corresponding position vibrates, helping the wearer…

TICKEY Clip-On Badge With E-Ink Display TICKEY Is a Small Clip-On Badge With an E-Ink Display That Can Show 48 Colors, Built on an ESP32

TICKEY is a compact clip-on gadget that combines a 3.7-inch, 720 × 480 color e-paper display with an ESP32-S3 microcontroller, Wi-Fi, Bluetooth and NFC. Instead of behaving like a normal LCD or OLED screen, its e-paper display is designed to keep a static image visible without continuously consuming display power. Users can show pixel art, photos, digital badges, QR codes, notes or personal…

Cat Wearing Smart Collar Monitoring Health Behaviors Cat Collar Fits Two AI Models' Runtime Memory Into 48KB of Its 256KB RAM by Never Running Them Together

An open source project called Meowtion packs two on device AI models onto a single microcontroller with only 256KB of RAM, using a scheduling trick rather than model compression to make it fit. Built by Jerome Graves and documented on Hackaday.io, the wearable collar tracks a cat's eating, drinking, and resting behaviour to flag early changes that can precede illness.

The collar runs on…
