⚙️ Therapy Hair Helmet
Hi, Hardwirers!
Everything is shrinking in size but expanding in agency.
Red-Light Therapy Hair Helmet
What is it: CurrentBody LED Hair Growth Helmet is an FDA-cleared wearable that delivers low-level red light (620–660 nm) to the scalp via internal LED strips. Designed for 10-minute daily sessions, it runs on a rechargeable battery and supports Bluetooth audio playback. The company claims it targets hair follicles to promote growth and improve scalp circulation with consistent use over several months.
Screen-Filled Puzzle Cube
What is it: Rubik’s WOWCube is a $399 electronic reinterpretation of the classic Rubik’s Cube. Built as a 2×2 modular cube, it features 24 small IPS displays, internal processors, speakers, gyroscopes, and rechargeable batteries. Beyond a simplified twistable puzzle, it runs built-in games, widgets, and downloadable apps via a companion mobile app and charging dock.
$10K Ring Hack Bounty
What is it: The Fulu Foundation is offering a $10,000+ bounty for a method to modify Amazon Ring Video Doorbell cameras so they stop sending data to Amazon servers while keeping hardware features like motion detection and color night vision intact. The solution must work with local PCs or servers, use accessible tools, and be replicable by moderately technical users in under an hour.
Titanium Smart Ring With ECG
What is it: Smalth Titanium Pro is a titanium-bodied smart ring with built-in ECG monitoring, 24/7 heart rate and SpO₂ tracking, sleep analysis, and activity logging. Measuring 7.6 mm wide and rated 10 ATM for water resistance, it offers up to seven days of battery life (extended via charging case) and syncs with a companion app—without requiring a subscription fee.
Credit-Card ESP32 Computer
What is it: M5Stack Cardputer Adv Version is a $30 credit-card-sized handheld built around an ESP32-S3 microcontroller. It includes a 56-key keyboard, 1.14-inch LCD, 1W speaker, microSD slot, Grove connector, IR emitter, and a 1,750mAh battery. The Adv version adds a 14-pin header, 3.5mm audio jack, and IMU. It can be programmed via Arduino, ESP-IDF, PlatformIO, or UiFlow2 for portable computing and hardware control tasks.
Lego Interactive Smart Brick
What is it: Lego’s Smart Brick is a sensor-packed 2x4 brick designed to bring physical Lego sets to life without screens. Embedded with motion, light, and sound sensors, a speaker, LEDs, NFC, and wireless charging, it enables play scenarios where vehicles react to movement, ships change sound as they tilt, and minifigures alter behavior when attached, launching March 1 with Star Wars sets.
Battery-Powered Smart Smoke Alarm
What is it: Kidde’s Ring Smart Smoke + CO Alarm is a Wi-Fi–connected smoke and carbon monoxide detector developed with Ring. Powered by two AA batteries, it installs without hardwiring, allowing placement beyond existing electrical junctions. It connects directly to the Ring app for remote alerts and Alexa integration, with no additional hub required.
India’s AI Glasses Debut
What is it: Sarvam Kaze is an AI-powered wearable from Indian startup Sarvam AI, previewed by Narendra Modi at New Delhi’s AI Impact Summit. Designed as a domestic rival to Ray-Ban Meta Smart Glasses, the glasses capture audio and visuals, respond in real time, and support custom experiences via Sarvam’s platform, with a May launch planned in India.
Angle-Blocking OLED Display
What is it: Samsung Galaxy S26 is expected to feature a built-in “privacy display” using Samsung Display’s Flex Magic Pixel panel. The OLED can adjust viewing angles on a pixel level, allowing specific apps or screen areas to appear blacked out from side views while remaining visible to the user, with AI selectively protecting sensitive content.
