High-performance 3-axis stepper motor control panel
Curious Scientist Mar 05,2024
In this project, I show you my new development which is a high-performance 3-axis stepper motor control board. It is high-performance because it uses the super-fast Teensy 4.0 microcontroller and it also uses a modern TMC429 stepper motor ramp generator controller together with three TMC2209 stepper motor drivers. The board can be controlled via buttons and a joystick, and I also programmed it to be fully controllable by sending commands and parameters via the serial terminal.The board is origin...

Pico Powered DC Fan Driver
Arnov sharma Mar 04,2024
Hello everyone and welcome back.So here's something cool: a 5V to 12V DC motor driver based around a Raspberry Pi Pico Board and a couple of electronic components.The Raspberry Pi Pico is the heart of this project.In order to drive the DC motor load, we have integrated the AO4406 N-channel Mosfet IC, a high-power Mosfet used in SMPS for fast switching purposes. Its Vds is 30V and it can withstand a maximum of 13A of current.In a future project, we will use this arrangement in a PC project t...

DIY extremly Sensitive and cheap Arduino Seismometer
Pavleski Mar 01,2024
 A seismometer, is an instrument used to detect and record ground motion caused by seismic waves, such as those generated by earthquakes, volcanic eruptions, or other sources of ground vibration. Basically, the seismometer consists of two parts, and one part is a sensor that detects the earthquake and converts it into an electrical signal, and the other electronic part that amplifies, processes and records this weak signal for further processing.  In the previous video , I describ...

HANDHELD MULTIMETER V4
ELECTRONOOBS Mar 01,2024
This device can measure anything, anything. Even the flatness of the earth. Naah guys, just kidding. But I think this will finally get to be the best multimeter for makers and small electronics projects. This is my new version of the two/hand multimeter made with Arduino capable of measuring all these units and more to come because is getting better by the day… I was tired of trying all types of sliders and switches, and I decided to make my own dial, so this time the project is made o...

Arduino UNO Shield for two Transparent Potentiometers
upir Feb 28,2024
Learn how to spice up your project with a potentiometer by using a transparent potentiometer that can shine! All this is done by placing a 3mm LED inside the potentiometer since it has a hollow shaft made from transparent plastic. And if you add a transparent knob on top of it, it will look great. In this video, I will also show you how you can create a custom PCB in the form of an Arduino UNO shield.Screenshots from the video:
