Drone Detection
Bandini Apr 27,2026
Drone Detection SystemAs part of a symposium presentation, I decided to build several drone detection prototypes using different approaches: image-based detection, audio, and radio frequency.For image-based detection, my initial idea was to train a machine learning model and deploy it on a dedicated Linux board with a camera array. Instead, I chose a simpler and more engaging approach that attendees could easily replicate—even without much maker experience.SenseCAP WatcherSenseCAP Watcher is an ...

Electronic Fish Feeder
silicioslab Apr 24,2026
Never forget to feed your fish again and with the right amount, at the right time.Regular feeding is one of the most important factors for the health and growth of fish, whether in home aquariums or larger breeding systems. However, maintaining this consistency manually is not always practical, especially in busy routines or during periods of absence.With this in mind, this project presents an automatic feeder developed with 3D printing, designed to be simple, efficient, and accessible. Using a ...

DTMS (Distribution Transformers Monitoring System) Module
Apr 21,2026
DTMS (Distribution Transformer Monitoring System) is a distribution transformer monitoring system designed to monitor operational conditions in real time. This system not only measures transformer oil temperature using a PT100 sensor acquired through the MAX31865 module to ensure high accuracy, but also reads electrical parameters at each transformer terminal, such as voltage (V), current (I), power (P), power factor (PF), and other parameters via Modbus RS485 communication from an external mete...

Robot Car Real Time Physics Controller using variable inertia for Programming Cosmic Dynamics based on NKTg Law
Apr 18,2026
NKTg Law Robot Car — Build Your Own Physics-Controlled RobotBackgroundThis project is based on the NKTg Law on Varying Inertia by Nguyen Khanh Tung (ORCID: 0009-0002-9877-4137). The law states:NKTg = f(x, v, m)NKTg? = x × p = x × m × v → Orbital Stability ParameterNKTg? = (dm/dt) × p → Mass-Momentum Exchange ParameterUnlike classical physics that treats mass as constant, NKTg treats mass as a variable — making it ideal for robots that carry, pick up, or drop cargo.Parts List & Estimated Cost...

Signal Function generator
ZS6ZF Apr 15,2026
This board functions as a signal generator, using a 4060 IC to produce various frequencies in both square and sine wave formats. To access the sine wave output, use a jumper to bridge J2 and J1. Note that the sine wave is pure AC, whereas the square wave includes a DC component.

Arduino Servo Motor Control
Jain Apr 14,2026
Precise motion control is at the heart of many modern electronics projects—from robotic arms to camera stabilizers. One of the simplest ways to achieve this is by using a servo motor with a microcontroller like the Arduino Uno.In this project, you’ll learn how to control a servo motor’s position using Arduino. Whether you're a student exploring embedded systems or a In this guide, we’ll not only interface a servo motor with Arduino but also take it a step further by briefly building a simple ser...

CNC Dust Shoe Controller
Wieland Apr 13,2026
This is a standalone single axis CNC controller designed to control a stepper motor actuated dust shoe lift. It has inputs for home sw, limit sw, up btn, dwn btn, up override for controller connection (with optocoupler). It outputs a signal when the dust hood is up. To control there is a rotary encoder and 16x2 LCD. The stepper output is step and direction for use with external stepper driver.The code works, but could use some improvement.Use at your own risk, no support provided.
