Antweight Battlebot (454 grams) with a machined titanium spinner.
Currently in the process of creating my High School's battlebot team with my friends! We are in the process of getting the titanium spinner machined and shipped to us, and or...
This project dates back to the last year of my bachelor degree. The professor for the "Electronic laboratory" course decided to give a twist to final examination allowing two options: standard examination or a project contest. Rules were si...
Electronic vintage weather station
In the past, some houses had small weather stations that showed the data of humidity, atmospheric pressure and temperature that were in that area by means of spheres, these spheres were framed in tables...

Introduction
Hi, I'm Carlo, and I'd like to share my experience with a very interesting board, the UNIHIKER K10. I'm a middle school teacher an...
Introduction
LumiDial is a custom-built wristwatch that blends classic analog style with modern LED technology. Instead of using physical hands, it uses 72 SMD LEDs arranged in a circular layout — 60 LEDs to indicate seconds and minutes, a...
I would like to proudly present my battery-powered, RP2040-based handheld with a color screen and four reconfigurable test probes that measures voltage, resistance, frequency, and logic signals — and can just as easily generate PWM, drive ...
ESP32 nRF24 Walkie-Talkie (Main Description)
This project is a wireless communication terminal built on the ESP32 microcontroller, utilizing the nRF24L01 2.4GHz transceiver module for data transmission. The system features a 0.96" I2C OLED display to...
For interesting STEM demonstrations at schools, I had built a small hobby robot called the Orange Giraffe Hunter.
Its job was to look around , lock in, and chase down a plastic Orange Giraffe
The prototype build used an Arduino Uno...
The inspiration
Let's be honest, our grandparents hate smartphones. They find it hard to navigate through menus, forget where the emergency button is, and often want nothing to do with modern technology. On top of that, the world is full of electroni...
Introduction
I'm currently waiting to receive the hardware for the Raspberry Pi Compute Module 5 Development Kit RoadTest. My motivation for applying for that roadtest is to replace a Home Assistant (HAOS) home automation system that I have...
This PLC board is designed using a Cypress System-on-Chip (SoC) microcontroller for industrial automation and embedded control applications. The Cypress SoC integrates a microcontroller with programmable analog and digital peripherals on a single chi...
AEGIS is a fully custom-designed robotic arm that I designed, 3D printed, assembled, and programmed from the ground up over the past month. My inspiration came from JARVIS in Iron Man—the idea of building an intelligent robotic assistant that c...
The Expressive AI Desktop Robot CuteBit is an open-source, voice-controlled AI robot that combines a powerful Local LLM "Brain" (running on a host PC) with an expressive ESP32 "Body". Unlike standard voice assistants, CuteBit has ...
