The most popular flight controller for INAV – Q4 2017
It's been a few month since, for the last time, I presented to you the most popular flight controllers used together with INAV firmware. So, as you can suspect, it is time for the next one. This time, I've looked into last 3 months of the year 2017: October, November, and December. Important, this is…

How to wind an electric brushless outrunner motor with dLRK winding schema, part 2
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.

LoRa versus FSK modulation signal spectrum
LoRa modulation is a wireless communication technique designed for long-range, low-power data transmission. It is based on Chirp Spread Spectrum (CSS) modulation, which spreads the signal over a wide frequency range, making it robust against interference and noise. This technology is particularly useful for Internet of Things (IoT) applications, where devices need to communicate over…

Crossbow LRS: first live test that is almost a success
Finally, much later than I originally expected, Crossbow LRS, my DIY medium range RC radio link was used to control something that flies. Not much, and not far. It was only my experimental 6″ GPS Racer quadcopter. And I reached only 350m. Small steps, I had no intention to beat and records after all. Just…

CC1101 868MHz Wireless Transciever Pinout
CC1101 is another example of modern radio modules. I might not have the receiver sensitivity or LoRa SX1276, but with proper antennas should give more than 1 km of radio transmission. Recently I got a couple of them, so expect some new projects with CC1101 and Arduino. Now, something that took me some time to…

RaceFlight One GPL violation drama, there might be more of that
Previous parts of this cycle are available here and here. Betaflight community has a grudge against RaceFlight. And they have a reason. Two potential, or maybe I should say confirmed, GPL violations in one year is fully enough. That just does not looks good no matter how you look at it. This whole situation stinks.…

Standalone Betaflight Configurator, since Chrome Web Store apps are dead
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?…

How FPV looked 2.5 years ago…
A few days ago I went back in time. Or to be more precise I started to browse my photo archive. And I’ve found pictures of my first FPV quadcopter… Oh my… ancient times… Doesn’t it look awkward? At least a little… But this baby was pretty cool to think about it. At least when…

RaceFlight One Source Code, drama continues
This is the follow up of yesterday entry RaceFlight One source code has been published and what does that mean. Before you continue I suggest reading that post first. Another day, another drama. Or rather the same drama continues. There are two major updates on the topic of RaceFlight source code and team conflict. RS2K…
