DIY Bench Power Supply
Arnov sharma Jul 23,2024
Greetings everyone welcome back, and here's a powerful project, the DIY Bench Power Supply. With the exception of the PSU we used, which was extracted from an old Ender 3 printer, everything was made completely from scratch.Here, we are using the ZK-4KX DC-DC Buck Boost converter module, an adjustable regulated power supply module with a voltage range of 0.5–30V and 4A. It can be used for a number of power-related applications, such as solar battery charging, as a boost converter to drive high-p...

Build a simple 3D Arduino Mini CNC Plotter
KILIC Jul 22,2024
Hi friends, we will see how to make a simple and awesome mini CNC plotter machine in this project. I saw this project on Thingiverse a few days ago and found it very interesting, so I decided to make a video with all the steps.The project is based on Arduino and includes GRBL code. It contains three hobby stepping motors and 3D parts that provide movement in three axes. I start the first step of the project by assembling the 3D parts and stepping motors that make up the main structure of the pro...

Interfacing IR Sensor Module with Arduino Nano
Jain Jul 22,2024
In this project, we will learn how to interface an Infrared (IR) sensor module with an Arduino Nano. IR sensors are widely used in various applications, such as obstacle detection, line following robots, and remote control systems.What is IR Sensor?An Infrared (IR) sensor consists of an IR transmitter and an IR receiver. The IR transmitter emits infrared light, which is reflected by objects in front of the sensor. The reflected light is then detected by the IR receiver. Depending on the intensit...

DIY Ultra Sensitive Theremino-Arduino Polygraph, Scientology E-Meter
Pavleski Jul 19,2024
 A polygraph, commonly known as a lie detector, is a device used to measure and record several physiological indicators such as blood pressure, pulse, respiration, and skin conductivity while a person answers a series of questions. The basic parameter on the basis of which the reliability of the response is determined is the galvanic skin conductance. The device presented in this video is basically a galvanic skin conductance meter with several additional advanced functions and setting...

Wand of Illumination
Arnov sharma Jul 18,2024
Greetings everyone and welcome back! This is the "Wand of Illumination," a 3D-printed wand combined with a flashlight incorporated inside.Utilizing one of the Harry Potter wands as a model, we have created a new wand from scratch. Inside the wand, we then installed a fully operational flashlight circuit.An Attiny13A 8-bit microprocessor connected to a switch that toggles the white 5mm LED makes up the flashlight circuit. A 3.7V, 50mAh LiPo cell that we added inside the wand serves as t...

VGA-AVR: An Arduino-Compatible VGA Shield for AVR Microcontrollers.
Net Jul 17,2024
The VGA-AVR is an Arduino-compatible shield designed for outputting video to any monitor and receiving data from any keyboard with its onboard VGA connector and PS/2 6-pin Mini-DIN connector. The shield was designed originally for hobbyists who wanted to make something retro and useful with their Arduino, particularly those who wanted to replicate the technology of the 80s, such as the Apple II and the Commodore 64. It would be nice if anyone develops some software for this shield but it support...
