Virtual Private Networks (VPNs) have become increasingly popular in recent years, touted as essential tools for enhancing online privacy, security, and freedom. By encrypting internet connections and masking IP addresses, VPNs offer users a sense of anonymity and protection from prying eyes, whether it’s ISPs, hackers, or government surveillance agencies. However, while VPNs undoubtedly offer … Read more

There are times, when you have purchased your brand new Single Board Computer like a Raspberry Pi for a headless project and then you realize – you don’t have any monitor laying around for the initial computer setup. But if you have a laptop next to your lap – there might be a solution for … Read more

This blog post should answer (or at least try to) the question, if Fusion 360 could be used for a living space’s interior design. The reason why I decided to make a post about it, because at one point in my life I was searching for a such answer myself. To tell you the truth, … Read more

There are lots of cheap USB-Serial adapters on the market which most of the time are perfect solution if you want to flash a MCU or you need a data connection between a PC and some kind of device with serial interface. But those cheap solutions are not suitable if electrical isolation between a PC … Read more

If you have ever designed your own PCB with ESP12 module on it, probably you have left some kind of a connector to program the module. But what if you don’t want to have an extra connector or you don’t have enough space on a PCB? Then you could use an pogo addon for ESP-12 … Read more

Handful of older generation AVR MCUs needs ISP (In System Programming) connector to flash your own firmware. Usually if you design your own PCB, you will place somewhere 6 pin header (2×3 pins) as ISP connection. Most of the time it makes sense, unless PCB needs to be small especially in its height. In these … Read more

This project is mainly oriented to writing a basic WEB user interface for ESP8266. The temperature sensor will be more like an addition to the project instead of being project’s main topic. You can split ESP based projects into two main types: 1) a device with a battery and 2) a device which is powered … Read more

This is probably the simplest way of making a PCB at home. Although with this method the board will not look nowhere near to the professionally made ones, it will do its function. Also, because it involves drawing the traces by hand, it is mostly suitable for making PCBs where bigger SMD or Through Hole … Read more

Lots of LED strip control circuits use Pulse Width Modulation (PWM) to control light brightness. Although it is quite simple method, it creates (sometimes) unwanted phenomenon called flicker. While usually unnoticed by a human eye, flicker can still cause some discomfort to the individual. To reduce LED flicker, a high PWM frequency or analog control … Read more
