ESP32 CAM AI Vision Assistant Pendant ESP32-CAM AI Vision Assistant Pendant for the Visually Impaired

Moving through unfamiliar environments is a challenging thing for visually impaired people. We have a lot of solutions, from sticks to obstacle-avoidance handheld devices on the market, to solve their problem. In the DIY world, a lot of makers have built obstacle-avoidance sticks using Ultrasonic sensors, IR sensors or even a PIR sensor and different variations of…

 Arduino Round Segment NeoPixel Clock Arduino Round Segment NeoPixel Clock

Digital clocks are one of the most popular Arduino projects, and most of them use traditional seven-segment displays to show the time. While these displays are simple and reliable, they usually have the same familiar rectangular shape and monochrome appearance. When I decided to build a new digital clock for my room, I wanted to create something that worked like a seven-…

Petoi Unveils Four Servo Open Source Quadruped Robot Quaddle Is an Open-Source Desk Robot That Can Move Omnidirectionally With Just 4 Servos

Petoi, the team behind the open-source Bittle and Nybble quadruped kits, has opened early access for its next robot, Quaddle. The company describes it as a four-servo quadruped capable of walking, strafing sideways, and spinning in place, a claim that stands out mainly because of how few actuators it uses to pull it off.

Most legged robots that can…

DIY ESP32 Wall Climbing Robot We Built an ESP32 Wall Climbing Beetle Robot

We can see wall-climbing robots from hobby-level to serious problem-solving ones that are used for inspection, surveillance, cleaning, etc. When we generally talk about robots, a robot can be a firefighting robot, a human-following robot, a self-balancing robot or can be of any type that has some specific features or solves a specific kind of problem. If we talk…

IoT Pet Tracking System with GPS and Geofencing How to Make an IoT Pet Tracking System with GPS and Geofencing

"Where did my pet go?" If you have a pet, you've probably asked this question at least once. One moment they're playing happily in front of you, and the next... they're gone! Maybe they saw a butterfly, started chasing a bird, or simply decided to go on a little adventure without telling you. A GPS pet tracker solves this problem before it turns into a crisis. Now…

Litewing Drone with Object Tracking How to Build an ESP32 Drone with Object Tracking Using LiteWing

Most people assume object tracking for autonomous flight is very complex, but it doesn’t have to be that way. All you need is a different way of looking at the problem. We built this project to see if we could make a simple LiteWing drone behave intelligently using just a laptop and a basic camera.By placing the camera above the room ceiling, the floor becomes a…

Send Data from ESP32 to Firebase Realtime Database How to Send Data from ESP32 to Firebase Realtime Database

In this tutorial, we’re going to learn how to send data from an ESP32 to Firebase Realtime Database. We are using ESP32 Firebase Google as our cloud platform. A lot of cloud-based IoT projects on YouTube / GitHub / similar platforms using ESP32, ESP8266, UNO R4, or similar microcontrollers use Firebase as the cloud platform. And this guide covers the complete ESP32…

 Hot Wheels car has been transformed into a fully functional FPV RC drift platform by YouTuber Pro Know Hot Wheels Meets Embedded Engineering: Inside a 1:64 Scale FPV RC Drift Car

A Hot Wheels car has been transformed into a fully functional FPV RC drift platform by YouTuber Pro Know, proving that serious embedded engineering can exist even at a 1:64 scale. The project replaces the toy’s original internals with an ESP-based microcontroller running custom firmware, paired with a purpose-built PCB that integrates control logic, power…

Multi Geofencing System Using IoT How to Build an IoT-Based Multi-Geofencing System for Smart Tracking

We're all familiar with live GPS tracking; it tells us where a vehicle or device is right now. But what if the system could do more than just show the location? That's where geofencing using IoT comes in.  Imagine receiving an instant alert the moment a vehicle leaves home, reaches college, enters the office, or moves into a restricted area. Instead of…

Smart Parcel Tracking System Using IoT How to Build a Smart Parcel Tracking System Using IoT

Imagine you've just sent a parcel through a courier service. As soon as it leaves your hands, you start wondering what is happening to it. Is it being handled carefully? Has it been dropped or damaged? Is it still on the right route? Will it reach the destination safely and on time? The truth is, once we send a parcel, we have very little idea about what happens…

DIY Flight Tracker Using ESP32 DIY Flight Tracker Using ESP32

This should be the easiest and cheapest way to build a flight tracker system. Maker from the Youtube Channel - Tech Talkies recently built this incredible DIY flight radar that runs entirely on an ESP32-S3 Zero, a round GC9A01 display and a rotary encoder. All the parts assembled onto a custom made 3D printed enclosure. Instead of capturing radio waves locally, it…

DIY IP KVM Built Using the ESP32-P4 ESP32-P4 Powers a DIY IP KVM for Remote PC Control

Remote access devices like IP KVMs are usually built around powerful single-board computers such as the Raspberry Pi. But what if the same job could be handled by a microcontroller instead? That's  what creator Jonathan Rowny set out to explore by building a functional IP KVM using Espressif's ESP32-P4. The project aimed to remotely stream a computer's display…
