This is one of the most frequently reported things about every new version of INAV Configurator: from time to time, it starts minimized and it can not be made visible. It is a bugger connected with a fact that INAV Configurator does not have an installer. It's just "download and run" and after releasing a new version, we can not delete stored data during install. Since there is no install process.
Your magnetometer/compass is not working with INAV? Is the sensor red in Configurator? You are not the only one… Not only most popular compass HMC5883l is discontinued and what you get are Chinese clones, chip labeled 5883 might not be HMC5883l but something completely different. And I2C bus is very very picky and likes to give up on you….
This is how you might fix your problems: add pullup resistors for I2C SCL and SDA lines and/or lower
Few weeks ago I've decided to shoot more tutorial videos about INAV and this is the first effect of that decission: INAV Troubleshooting: why INAV is not arming
In this video I talk about where to search for the reasons of INAV arming problems and how to solve them. And yes, it is about famous navigation is safe message too.
Here is another of my tutorial YouTube videos. This time, I talk a little about parallel LiPo charging: why to do it, how to do it and
why it might be dangerous when you do it wrong:
My memory is not as good as it used to be. I just realized, that third part of my motor winding series was not yet announced over here. So here we go…
In this video I terminate motor into Delta pattern and do first test of freshly winded motor.
Google finally did what they announced last year: Chrome Packaged Apps for Windows, Mac, and Linux are dead. OK, maybe not 100% dead, but they were removed from search and browse in Chrome Web Store. If you still have link, you can install (no idea for how long tho).
So, how to live with that? Our hobby is driven by Chrome Packaged Apps. Betaflight Configurator, INAV Configurator and Cleanflight Configurator are all Chrome Packaged Apps. Did we lose the ability to set up our drones? Luckily no. Thanks to fantastic project NW.js, chrome apps can be packed together with Chromium and distributed as a single file without dependencies. I've prepared a short video how to install Standalone Betaflight Configurator, for INAV it's the same procedure. And for Cleanflight… well… Cleanflight is dead. Or rather dying…
This time, another "motor winding" video. In 13 minutes and something seconds I:
- show some tool that I find useful for motor winding
- wind a 12N14P brushless outrunner electric motor with dLRK winding schema
- terminate this motor into Delta configuration
BTW, in next video I will show you if it worked or not 🙂
Motor winding adventure continues. In this video I show and tell about:
- 12 coils (12N)
- 14 magnets (14P)
- dLRK winding schema
- WYE and Delta termination schemas
Today another video tutorial. It's just simpler to show how to make something on video than with text and images. So, without further ado: How to make Inverted Vee antenna for 5.8GHz FPV at home. All that is required is:
- coax cable (here RG316)
- SMA/RP-SMA connector
- copper welding wire
- soldering station
- basic tools
At the end we have small and light FPV antenna that just works. Sometimes it's just worth to make something by yourself, right?
With upcoming Betaflight 3.2, we will be given a new, outstanding, new feature: dynamic filtering. An belive me, it was worth waiting for Betaflight 3.2 only to get it. I do not care much about other changes that happened with version 3.2 but dynamic filtering it the thing! In this post I will explain, in simple words, what is dynamic filtering and how to enable it.
The problem of noise
Gyro has a nasty tendency to pick up a lot of noise. Vibrations. After all, there are a lot of things that can vibrate (motors, propellers) and resonate (frame). Without a good way to filter all that noise out, our racers would not fly as good as they fly now. And you would be replacing motors and ESCs even more often. I you want to know more about gyro noise sources and filtering, please watch my Gyroscope and filtering series on YouTube.
