Smart Home
ReAir Smart Vent
A 2022 prototype: a Wi-Fi-controlled ceiling vent with three independently-driven blades, Qi wireless charging, and an 18650 battery.
Autonomous Robot
Everyspot Garden Rover 2026
A 4-wheel-drive garden patrol rover: a Raspberry Pi 5 watches through an OAK-D Lite stereo depth camera on a pan/tilt gimbal, navigates with GPS + IMU, and waters through a solenoid sprinkler that aims where the camera looks. Runs off a 4S 18650 pack on a coherent four-rail power system.
Robot
Robot Arm 2026
A 4-DOF desktop pick-and-place arm on the EEZYbotARM Mk2 four-bar topology — yaw, shoulder, elbow and a geared gripper. ESP32-S3 + PCA9685 driving three MG996R servos and an SG90 gripper, on a 4S 18650 pack. Every component modeled from real vendor CAD.
Smart Home
Drip Irrigation Controller 2026
An off-grid, solar-powered drip-irrigation controller. It sits on a bucket of water and doses a garden through a printed 10-outlet manifold with a 5 V peristaltic pump. Solar + 18650 battery run it unattended; an ESP32-S3 schedules watering and senses bucket level, temperature and light.
Smart Home
Hydroponic Plant Pot 2026
Countertop passive-Kratky hydroponic pot. A plant grows in a net cup with its roots in a nutrient reservoir; an ESP32-S3 monitors pH, EC and light and runs a WS2812 grow strip. USB-C powered — no battery, no air pump. A clear window shows the water level.
Smart Home
Smart Plant Pot 2026
USB-C self-watering soil pot. A capacitive moisture probe and ambient-light sensor sit at the plant; an ESP32-S3 in a separate desk-side enclosure with a 1.02 L lift-out reservoir doses water through a 5 V peristaltic pump when the soil reads dry. USB-C in, 5 V throughout — no battery, no BMS, no buck.
Autonomous Robot
Robot Car
A tabletop-scale autonomous rover — first with three wheels and a Raspberry Pi camera, then with four wheels and a Google Coral Edge TPU running vision on board.
