⚙️ Fartbit Digestive Monitor
Hi, Hardwirers!
Hardware keeps absorbing intelligence in strange places—kitchens, sleeves, tires, watches, even the air inside the human body.
Fartbit Digestive Monitor
What is it: Researchers at the University of Maryland developed “Fartbit,” a wearable sensor designed to track digestive gas activity. The device measures the frequency and volume of gas passed throughout the day as part of a project called the Human Flatus Atlas. Participants also log food intake through an app so researchers can study links between diet and digestive gas production.
Wear OS Earthquake Alerts Upgrade
What is it: Google is updating its earthquake alert system on Wear OS smartwatches so alerts can appear even when the watch is not paired with a phone. Delivered through Google Play Services v26.07, the feature allows compatible watches—likely those with cellular connectivity—to receive warnings directly. The system uses Android device sensors to detect tremors, estimate earthquake magnitude, and send alerts to nearby users.
Lenovo AI Workmate Robot Arm
What is it: Lenovo AI Workmate Concept is a desktop robotic assistant featuring a small articulated arm and a screen displaying animated eyes. Using local AI, it supports voice and gesture interaction. The device includes a camera for scanning documents and notes to generate summaries or presentations, and a built-in projector that can display content on a desk or nearby wall.
Ultrasonic Chef’s Knife
What is it: Seattle Ultrasonics C-200 is an 8-inch chef’s knife with built-in ultrasonic vibration technology. A removable battery inside the handle powers piezoelectric crystals that vibrate the blade at around 30,000 times per second. Pressing a button on the grip activates the vibration while cutting. The knife uses AUS-10 steel, supports USB-C or wireless charging, and is designed for standard kitchen prep tasks such as slicing meat, fish, vegetables, and herbs.
Wireless-Charging Laptop Sleeve
What is it: Razer Laptop Sleeve 16” is a padded laptop sleeve with integrated Qi2 wireless charging pads built into its flap. Designed for laptops up to 16 inches, it protects devices during travel and can wirelessly charge a smartphone (up to 15W) and accessories like earbuds (up to 5W). The charging pads draw power from a laptop through a USB-C connection.
Wheelchair Turns Into Camera Rig
What is it: The Caerus Steadicam is a camera stabilization system developed by filmmaker Christopher Lynch that mounts onto the self-balancing Genny Zero wheelchair. Designed for film production, it lets wheelchair users operate broadcast cameras while moving smoothly, enabling tracking, orbit, and follow shots without traditional body-mounted Steadicam rigs.
Retractable Stud Winter Tire
What is it: Nokian Hakkapeliitta 01 is a winter tire with metal studs that automatically extend or retract depending on temperature. The tire uses layered materials that stiffen in cold weather to push studs outward for ice traction and soften in warmer conditions so the studs retract below the tread. It is designed for snowy regions in Europe and North America.
Donut Lab Solid-State Battery
What is it: Donut Lab developed a 3.6V 26Ah solid-state battery designed for high-temperature environments. Tests by Finland’s VTT research center showed the cell could operate and discharge power at temperatures up to 100°C, while slightly increasing capacity compared with room temperature. The battery targets applications such as electric vehicles, motors, and other systems that operate under demanding thermal conditions.
Single-Ball Self-Balancing Bike
What is it: Maker James Bruton built a prototype self-balancing bike that rides on a single large ball instead of wheels. Three custom omni-wheels drive the ball from different angles, while motors and sensors stabilize the vehicle in two axes. The rider controls movement by leaning or using twist-grip inputs, allowing the bike to move forward, sideways, or rotate.
