Robotic Arm
Dec 25,2025
This my DIY robotic arm which is made up of foam and double sided tapes. There is an arduino uno r3 for the code. It is connected to two motors via drivers. The DC BO motor turns the arm right and left. The DC stepper motor turns it up and down. There is also a Q-box processor which is a custom driver thingy only avaliable in the QuadStore where I got most of my products from. It is only used for the power source since I only had a 6v barrel jack battery. It also connects the gnds togther. There...

Christmas tree made with e-waste and Arduino - WEEE
Perez Bongiovanni Dec 24,2025
Christmas tree made with WEEE is a project that I maintain every year, which I keep updating by adding new components. In this case, the addition is the base of an electric kettle, one more blue LED, and the on/off sequence of the LEDs is assisted by artificial intelligence.

Arduino UNO Bootloader Burner Shield
THAYER Dec 24,2025
This is a simple and very easy project for those that need to burn the Arduino UNO bootloader on ATMEGA328P ICs. I made this after seeing several online videos showing the process, but used a breadboard, jumper wires, and a few parts for the oscillator circuit. So ...

Standalone Arduino UNO Ver. 2
THAYER Dec 23,2025
A standalone Arduino UNO that features a female header for plugging in a USB to serial module for easy of loading sketches, no need for 5 wires cluttering up your project. This PCB allows you to customize the headers, male headers can be used on the bottom so the board can be plugged into another project. Female headers on top of the board,, plus you can have various colors or even extra long pin headers.

Pi Pico Fire alarm sound detector
Prof Dec 17,2025
Pi Pico Fire alarm sound detector running on W5100S Pico EVBIntegrating audio machine learning on Arduino platforms running Pico Mbed OS presents significant challenges, primarily due to the reliance on external audio libraries such as CMSIS-DSP, and TensorFlow Lite for Microcontrollers (TFLM). These libraries, while powerful, introduce complexities in compatibility and resource management, as they are not natively aligned with Arduino’s lightweight abstraction layers or the constrained runtime ...

WaterIT — Smart Irrigation and Plant Care System
Sahu Dec 13,2025
WaterIT is a smart plant watering and care system that I built to solve a problem I kept seeing around me: plants were either getting too much water or not enough, simply because people were guessing. At home and in school gardens, watering was usually done on a fixed schedule without checking soil condition, weather, or the type of plant. This often led to wasted water and unhealthy plants. I wanted to build something simple, affordable, and intelligent that could take decisions on its own and ...

How to make simple Variable HIGH VOLTAGE Power Supply
Pavleski Dec 11,2025
 High Voltage Power Supply is usually understood as a device that is capable of generating a voltage of several kilovolts, or even tens and hundreds of kilovolts. Most often, these power supplies give a certain voltage at their output. When experimenting with high voltages, we almost always need a variable value of the generated high voltage. There are several ways to achieve this, and in this project I will try to implement and explain all of these ways in one device. Of course, I will try...

DIY 5-Day Rainfall Forecast Device - ESP32 E-Paper Project
Pavleski Dec 05,2025
 In several of my previous projects I have presented ways to make weather stations, but this time I decided to make it a specialized device with a strictly defined purpose. Namely, at least in my experience, the basic weather information for planning any activity in the coming days is whether there is a chance of rainfall in that period. Unfortunately, in commercial, and even most DIY weather stations, this information is either not available at all or is quite brief in the form of a curren...
