Guide & Review
Sandeep Patil, CTO at RedNerds
Model Name: FNIRSI-1014DAbstract :An oscilloscope that retails at INR 13K basically covers all of the hands-on subjects a 4-year engineering syllabus teaches in theory. The only issue is that none of this is practiced. We barely get past MCUs hands-on.This… |

ESP32 Bluetooth Jammer Using Dual NRF24L01 Modules Bluetooth communication is everywhere. Due to its low power consumption, we can see it in a lot of our day-to-day gadgets. Behind the scenes, it's all about signals. Let’s explore what really happens when data is transmitted or disturbed via Bluetooth. This project is based on an ESP32 and two NRF24L01 modules, and we are going to learn how we can generate a 2.4 GHz… |

RC Jeep Uses a Servo-Powered Camera Rig for True Driver POV What if an RC car could make you feel like you’re actually sitting inside it? That’s exactly what creator kpopRC has built with his latest FPV Jeep crawler. Instead of a fixed camera, the system uses a servo-powered “lean-out” rig mounted in the driver’s seat position. This allows the camera to physically extend out of the window and move with pan and tilt controls giving a true driver’s… |
