Previously there was a post labeled with "idea" about a small device that can measure humidity, temperature and pressure, and it fits on keychain. The goal of this post is to show the process of making a PCB board for that device. Schematic was easy, considering how it

I wish I had a small device that can fit on a keychain that displays temperature and humidity of the room. Winter is getting to an end and the problem of dry air will soon be over. But in times of warm weather there is problem of high humidity. So

Considering how dimensions of a Gameboy color D-Pad are nowhere to be found on the internet. A long time ago I bought one of those and never really played it. So I will measure those dimensions myself. There it is. Dimensions of a case are not there, because I did
First thing I found out in researching this idea is that someone made almost same thing I'm trying to do: My idea was to put an epaper display instead of normal LCD. But reality does not end here. On Reddit there is a subreddit called r/Writerdeck. And

Before this post, there was post labeled as an idea for a clock made from STM32F411, aka Black Pill. In that post I used additional Real Time Clock component to make a clock, however. Turns out STM32F411 has its own RTC integrated in it. I should have noticed that while

Here I'm talking about programming some of the most popular STM32 boards called Blue pill(STM32F103) and Black pill(STM32F411). First the easiest method there is. ST-Link programming. ST-Link is a small device that looks like USB on one side, and on other side it has exposed pins.

Will get straight to the point and talk at the end of the post. 1. Enter the footprint editor 2. Create a new footprint library, and name it. 3. On the left side select the library you created, right click, and click "New Footprint". 4. You will be

Idea is to make a handheld device with a sole purpose of playing chess on it. The idea seems weird considering how it's possible to play chess on almost any smartphone. But nevertheless I think it can be a cool product. With a little searching I found Handheld
A small e-paper screen that displays current time. It's not connected to the internet, instead it has its own RTC IC and you set it as any normal wall clock, but it does not go on the wall. It will have two AA batteries. Considering how epaper consumes
It started with trying to make my own keyboard. Considering a newly acquired knowledge of designing PCB I thought it would be a simple project. And in some way it is simple, just there are a lot of small quirks that come up as project went on. As of making
Recently I tried to make a small humidity and temperature sensor board that was powered by ESP32 C3. The PCB design was made and boards and components are ordered separately. Which means I will assemble them. However, I have not expected how small ESP32 C3 chip really is. It'
