DIY Magnet Polarity Detector - How to Identify Poles with a Hall Sensor from a PC Fan
Pavleski Aug 27,2025
 Recently, while working on a project, I needed to determine the polarity of several permanent magnets of different shapes. At first glance, it seemed simple, bringing the magnets closer together to see if they attract or repel, but I still couldn't determine it precisely this way. So I came up with the idea of making a very simple electronic device that would display the poles of the magnets in a very elegant way with two LEDs with different colors for each pole. It can immediately be...

Light Meter Project - Making Dfrobot Unihiker K10 Work with Standard Arduino Libraries
Pavleski Aug 22,2025
 The other day I received a shipment with a UNIHIKER K10 development board from DFRobot, which I received as a prize. The device is excellently packaged in a branded box, protected from damage during transportation. I immediately asked for information because I have no experience with this development board so far. In fact, the device is based on an ESP32-S3 Xtensa LX7 microcontroller and an ILI9341 TFT display with a resolution of 320x240 pixels. The display is protected by a metal fr...

STM32F429 TFT DCMI v1.0
Mackey Aug 17,2025
STM32F429 DCMI & FMCSupports a 3.5" 16 bit parallel TFT display via FMC, and 8 bit OV5640 camera via DCMI.Note that this board doesn’t have any SRAM other than the SRAM on the STM32F429. This means that the camera data stream must be processed as it’s received.This board was designed to implement a key reader as an accessory for my key code cutter machine. This board works with my OV5640 Camera board.For more information about this board and the Key Reader project follow the link h...
