Guimbal
A simple guimbal with ESP32 and MPU6050
In the world of DIY electronics, gimbals are a fascinating way to stabilize cameras or sensors, enabling smooth movement and precise control. This article explores how to create a simple yet effective gimbal using an ESP32 microcontroller, an MPU6050 accelerometer/gyroscope module, and a pair of servos, all programmed with MicroPython.

The Internet of Things (IoT) continues to reshape how we interact with the world, enabling smart devices to collect and transmit data with ease. Among the many powerful tools available for IoT development, MicroPython stands out for its simplicity and efficiency, particularly when paired with the versatile ESP32 microcontroller. One common application involves gathering motion and orientation data using the MPU6050, a popular accelerometer and gyroscope sensor.
Kiss
KISS principle
KISS, an acronym for "Keep it simple, stupid!", is a design principle first noted by the U.S. Navy in 1960. First seen partly in American English by at least 1938, KISS implies that simplicity should be a design goal. The phrase has been associated with aircraft engineer Kelly Johnson. The term "KISS principle" was in popular use by 1970.

Algoritmos
Algoritmos genéticos
É difícil falar de algoritmos genéticos sem falar antes de Charles Darwin. A ideia de que organismos mais adaptados a determinados meios têm mais chances de sobreviver e repassar suas características a seus descendentes foi criada a partir das observações de uma figura que transformou a Ciência. Trata-se do naturalista Charles Robert Darwin, considerado um gênio cujas descobertas principais foram feitas a bordo de um navio de pesquisa.
Assintótica
Análise assintótica
A análise assintótica é uma técnica usada para estudar o comportamento de um algoritmo à medida que o tamanho da entrada cresce, especialmente para entradas grandes. Ela nos ajuda a avaliar a eficiência de um algoritmo em termos de tempo de execução e uso de memória, sem precisar executar o algoritmo para diferentes entradas. A análise assintótica fornece uma forma de expressar o comportamento de longo prazo de um algoritmo, considerando o impacto do aumento do tamanho da entrada.
Anarchy
Anarchy
Anarchy comes from the Latin word anarchia, which came from the Greek word anarchos (“having no ruler”), with an- (“not” or “without”) + archos (“ruler”) literally meaning “without a ruler”. The circle-A anarchist symbol is a monogram that consists of the capital letter A surrounded by the capital letter O. The letter A is derived from the first letter of anarchy or anarchism in most European languages and is the same in both Latin and Cyrillic scripts. The O stands for order and together they stand for “society seeks order in anarchy” (French: la société cherche l'ordre dans l'anarchie), a phrase written by Pierre-Joseph Proudhon in his 1840 book What Is Property?

Problemas
Solução de problemas
Um problema é um empecilho, um obstaculo para alcançar determinado objetivo. E pode acreditar a vida é repleta de obstáculos. Mas encarar problemas de forma pragmática e ter a capacidade de simplificar evitando generalizar um problema pode ajudar bastante.
Shell
Shell script
Steve Bourne wrote the Bourne shell which appeared in the Seventh Edition Bell Labs Research version of Unix. Many other shells have been written; this particular tutorial concentrates on the Bourne and the Bourne Again shells. Other shells include the Korn Shell (ksh), the C Shell (csh), and variations such as tcsh. This tutorial does not cover those shells.
