How to connect APM Power Meter to INAV
This topic was eluding me for some time now. It’s time fix the problem and finally present a short tutorial how to connect 90A APM Power Meter for flight controller boards running Betaflight / INAV software and equipped with Current Meter ADC input. I will not show where to connect APM Power Meter to flight…

Using PCA9685 with INAV
The PCA9685 PWM driver working as servo extender is no longer supported in INAV. Use S.BUS output and S.BUS servo extenders instead One of the hardware limitations of flight controllers that usually multirotor users ignores is a number of PWM outputs. To fly a quadcopter you need “only” 4 PWM outputs. Since most FCs have…

How to install and configure Betaflight
Latest Betaflight 3.0 is a new quality for flight controller software. It brings many new, cool, features comparing to previous versions. If you fly mini-quad or micro-quad, you have to check what Betaflight 3 has to offer. This tutorial will show how to install Betaflight 3 and how to configure it so mini-quad can go…

How to measure gyro noise frequency with Blackbox
Betaflight (and INAV) lowpass filter tuning can be a hard thing to do if you have not idea what is noise frequency you want to cancel. Sure, you can blind test or read tutorials. But what if I tell you, you can measure it quite precisely using only Blackbox logs? Or measure rotation speed of…

How to print PLA on glass?
When I got my first 3D Printer (Malyan M150) and got into 3D printing I was surprised how consumer not-ready technology this is. Sticking, not sticking, overextrusion, underextrusion, Kepton, blue painters tape, clogged extruder… Over the time, at least, I was able to get the whole 3D Printing process somehow repeatable. I think one of…

How to tune PID I-term on a FPV drone
With this entry I want to initiate short series of articles showing how to tune multirotor / quadcopter PID controller. Let’s call it a continuation of Blackbox series, but this time I will not relay only on Blackbox data. Yes, I will show few examples how given scenarios looks on Blackbox logs, but all steps…

Connecting ultrasonic rangefinder (Sonar) to INAV
Keeping constant altitude with a drone is not a trivial task. Specially, if drone is supposed to keep give altitude very precisely few meters above the ground. One of the reasons for it is difficulty of reading precise altitude. Barometer can drift when atmospheric pressure changes and can produce a lot of noise. GPS is…

How to program ATtiny85 with Arduino IDE?
What is ATtiny ATtiny is a fimily of microcontrollers by Atmel, the same company that provides ATmega series used widely in “real” Arduino. Comparing to ATmega, ATtinys are much simpler, smaller (usually), with less features. But also cheaper, easier to connect, using less energy, and trust me, in many many cases you do not need…
