This short article help you to easily handle footprints courtyard (outline) overlap (overlay) clearance violations in KiCad by writing custom rule exceptions for specific components, to get 100% clear DRC without registration and SMS 🙂.

This short note will help you get rid of ERC violations easily and in the most right way 😎.

Simple way to get binary and hexadecimal output files (firmware) from STM32CubeIDE project.

Small introduction in using plexiglas (acrylic) to make home-made electronic devices more good looking.

Fusion 360 is an impressive easy-to-use, intuitive and beautiful mechanical CAD but it cloud-based, so who knows what could be tomorrow 🙃😛.

So now we export all projects data in different formats to get reverse copy (backup) or switch completely to another CAD, such as FreeCAD ⚒.

How to use your electrical bike battery as power supply system (power bank) to charge you laptop, smartphone and have an LED light ☀? Here is an full assembly manual with chosen parts for build a custom high-power and high-energy power bank.

Compendium of information of use LEDs with reverse mounting techniques 🚨.

Easiest and most properly way to bunch changing of via hole sizes in Altium Designer.

If paths to your library files doesn't specified in the STM32CubeIDE (Eclipse) project properties (both source and include) the project will be unable to compile 😪. Here is clear steps to solve this problem with example 🤗.

Utterly simple and useful circuits for protect your device against incorrect power supply polarity (reverse polarity) connection:

• High Side (based on P-Channel MOSFET)
• Low Side (based on N-Channel MOSFET)

This really simple thing can save the life of your electronic device, without taking up much space, thanks to modern miniature transistors.

Simplest blinking circuit, implemented in small board with convenient mounting hole.

Easy way to open built-in serial terminal in STM32CubeIDE without any additional plugins.

This simple library give you a chance to using buzzer as sound notification with the possibility to set number of beeps and period between them.

Setup is very easy, because it's fully compatible with HAL and Cube code generator, all you need it's config chosen pin and set label BUZZER. And here is example of use:

Buzzer_Go(TBUZ_100, TICK_2);

Here is small essay with demonstration of work., that describes how to use ordinary breakpoints and special condition-breakpoints 😉.

STM32 microcontrollers have got internal temperature sensor, that connected to one of ADC-channels, that makes possible in easy way get your device temperature without any additional components. This rough measurements can be used to estimate gadget status.

Tested on: STM32F401CCU6 (Black Pill)
Temperature range: -40°C to 125 °C
Accuracy: ±1.5 °C
