All the INAV sensors: are they required or optional?
INAV can use various sensors to fly drones and airplanes: gyroscopes, accelerometer, magnetometers, barometers, GPS, OpFlow, rangefinders, and airspeed. Some of them required some are recommended and some are a purely optional piece of hardware. Here is the full list: INAV Sensors: Gyroscope and accelerometer Required. The flight controller will not boot without a gyroscope…

Espressif ESP32-S2
When Espressif release ESP32 WiFi & Bluetooth capable MCUs back in 2016, many things changed in the DIY and tinkerers community. We finally had a cheap MCU that could do real IoT stuff and was easy to use. However, the cheap ESP32 is not really cheap in relative terms. Sure, it is cheap, but there…

ESP8266 and ESP32 – the main differences
ESP8266 and ESP32 are the next best thing that happened to DIY world since Arduino itself. Thanks to development boards based on those MCUs brand new possibilities opened in front of all DIY and tinkering enthusiasts. With those two, not only we have cheap and powerful microcontrollers, but we can also make them talk to…

The new Microsoft Edge is much better that I expected
I’m not shy to switch to a new web browser every few months when needed. I was one of the first users or Firefox when it was still named Firebird (yes, I’m that old). I abandoned Internet explorer without looking back. After all, it was such a bad browser.

What is a PID controller and how it works?
The whole FPV hobby, and especially multirotor drones, work only thanks to control theory and PID controllers. They are the only thing that separates chaos and immediate flip-over from a stable flight. A regular multirotor has at least 3 PID controllers. If you enable any mode with self-leveling, the number goes to 6. Any GPS…

A very cool, futuristic looking, 3D printed quadcopter frame
I love this part of me being a creator and an influencer, where I can show you some amazing things created by other people. And today, the joy is double, because it is an extremely cool frame designed by a guy from Spain that goes under the nickname of Micrathene FPV. What it is? Well,…

Betaflight vs EmuFlight vs INAV
Which flight controller software flies better out of the box? You know, the stock, default settings, no tuning. Just flash and fly. Betaflight, INAV or maybe EmuFlight? I decided to test it on one of my 5-inch FPV drones and compare: Betaflight vs INAV, Betaflight vs EmuFlight and EmuFlight vs INAV. The results are divided…

What is EmuFlight?
Here is a short story of what is EmuFlight, how it differs from Betaflight and should you even care? To answer the question. Yes, you might want to take a look at it. It is different enough from Betaflight to consider it as a separate flight controller. And some people say it really fly great…

EmuFlight and INAV Matrix Filter
Matrix Filter will have its premiere together with EmuFlight 0.3.0 and INAV 2.5. Which of those two will happen first is still unknown. After originally developing Matrix Filter for INAV, I also ported it to EmuFlight code and already some time ago they accepted my code proposal and merged it. You have to admit, that…
