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… |

Two-Way Holographic Display with Wemos D1 Mini This display can show two different images at the same time - no VR headsets, no software tricks, just pure optics. This is a two-way holographic display made by Julius Makes. The whole idea is that two players, sitting opposite to each other, should see the mystery instructions meant for the other person. Plus, they should be able to see their faces through the… |

How to Make a Raspberry Pi Waste Segregation System Using CircuitDigest Cloud Running, running, every day, we keep running to work, school, and college. In this busy routine, many of us do not even have enough time to eat breakfast properly. Then where do we find the time to clean our homes? Even when we clean, because of laziness or lack of time, we often throw all waste into the same bin without separating biodegradable and non-biodegradable waste. This creates a… |

How to do Object Detection with Raspberry Pi Using CircuitDigest Cloud What if a device could see the world the same way humans do, seeing objects, recognizing them, and understanding what they are in real time? Just like our eyes capture visuals and our brain instantly processes them, from bottles and phones to people and everyday items. It will be pretty cool, right? That is exactly what this Raspberry Pi object detection project demonstrates. You can build a… |

How to Build an UWB Indoor Positioning System using ESP32 and Qorvo DWM3000 Building an indoor positioning system using ESP32 requires technology beyond GPS. While GPS trackers excel outdoors, indoor positioning system needs Ultra-Wideband (UWB) technology to achieve centimetre-level accuracy inside buildings. This guide shows you how to build a complete UWB indoor positioning system using the Qorvo DWM3000 UWB module with ESP32,… |

Repurposing a Wear OS Smartwatch as a Smart Gear Shift Display A DIY maker has repurposed an old smartwatch into a custom gear knob with an integrated display. Instead of letting the aging smartwatch collect dust, the project reuses its display, sensors, and processing hardware inside a 3D-printed gear shifter housing. The result is a unique modification that displays the vehicle's current gear position directly on the gear lever itself. What I… |

Build an ESP32 GSM Calling Device with Auto Answer Using GeoLinker In this project, we build a complete ESP32 GSM voice calling device using the GeoLinker GL868 board. The main idea of this project is very simple. When we press a push button connected to the ESP32 board, it will automatically call a fixed phone number. Also, if someone calls the SIM card inside the module, the call will be automatically attended, and we can talk… |
