Momo is a voice controlled quadruped robot spider with an animated face and a conversational AI personality. 8 servos, custom CAD chassis, Raspberry Pi.

A smart light switch for my room using an ESP32. It uses a servo motor to physically flip my existing light switch, and a PIR sensor to detect when someone walks in so the light turns on by itself. I connected it to a cloud MQTT broker so I can control it from anywhere, not just when I'm on my home WiFi, and built a simple web dashboard (hosted on GitHub Pages) where I can turn the light on/off manually, toggle auto motion detection, and choose how long it stays on after no motion. I also added a second page that logs when motion is detected with actual timestamps, but only once every 15 minutes so it doesn't spam the log every time I move just keeps a rolling 2 day history so i can see if anyone came into my room when im not home to steal my Ramen packs

A handheld mini camera built on an ESP32-S3-CAM live preview on a small SPI TFT screen, a physical shutter button to snap and save full res photos to a microSD card, and 18650 battery power via the board's micro USB input. Basically a tiny standalone digital camera from scratch.

KARTX aims to be a plug and play smart cart device powered by a Raspberry Pi with a mounted camera. As items are placed into or removed from the shopping cart, the system automatically detects and tracks them in real time, updating a running total displayed on a small screen attached to the cart itself. Shoppers can see their subtotal and tax live as they shop, and pay directly from the cart without needing to go through a traditional checkout lane or rescan every item. The goal is to reduce checkout friction and wait times by turning any standard shopping cart into a self contained autonomous checkout device.

A tiny desk robot I built that actually has a personality. Runs on an ESP32, shows animated eyes on a 1.8" TFT screen, and reacts to how you touch it. It also pulls live weather, keeps time, and has a calendar, all sitting on your desk just vibing.

a real time sign language translator using MediaPipe and TensorFlow that will detect hand gestures and body position to recognize common signs, displaying predictions live and speaking them aloud.
