  • Gyroscope and filtering video tutorial – Episode 4

    In this episode of “Gyroscope and filtering” I show you how to configure notch filters using Betaflight Configurator and INAV Configurator software. Previous episodes: Episode #1 Episode #2 Episode #3

  • VL53L0X Lidar is… disappointing

    I just finished first test flights with laser rangefinder VL53L0X and well, I’m disappointed. Before I will show any data, let’s review test conditions: VL53L0X configured for Long range mode: 2m 8PM, obscured sky, no direct sunlight Over concrete And it looks like this: Solid readout ended at more less 80cm. Above that, valid readout…

  • INAV jumped over the bench

    Let’s say I have almost a good news about sonar support in INAV: yesterday I flew terrain following mode with experimental INAV code. And did not crashed when shooting video below. I did crashed next code version, but that is only a minor detail, right? When shooting that video I did not touched throttle stick.…

  • If not HC-SR04 then what? US-100 maybe….

    A week ago I wrote that HC-SR04 ultrasonic rangefinder is crap and it is still true. Only around 1m useful range and very jumpy behavior above are at least problematic… There is a better solution. US-100 ultrasonic rangefinder. Comparing to HC-SR04, it has at least twice the useful range. My preliminary tests gave solid readout…

  • Marabou Stork decommissioned

    Depron airplanes are easy to build, but also do not last long. Few weeks ago I decommissioned by Marabou Stork. It did not crashed, it was flying almost fine, but it had at least a few problems: Motor was overheating. Just like that Wing that I originally designed for something weighting around 450g, now had…

  • INAV 1.7.2 has been released

    “Let’s do the news….” and INAV 1.7.2 has been released yesterday. Besides new targets (MATEKF405, Alienflight F7, SP Racing F3 NEO) there are few quite important changes: ADC channel to function mapping is now configurable. Any ADC using function (battery voltage, current, RSSI) can be assigned to any ADC pin. You smoked Current pin? No…

  • HC-SR04 is crap and there is nothing you can do about it…

    HC-SR04 is crap and there is nothing you can do about it…

    Only few days ago I mentioned that I started to reintroduce sonar support to INAV. When DigitalEntity told me that popular HC-SR04 is crap I did not belived him. I expected that “official” 4m range on a noise-machine aka quadcopter is unrealistic, but data I recorded today clearly shows: HC-SR04 is crap and is absolutely…

  • Flight Controller Soft Mount – is it worth it?

    Is it worth to soft mount flight controller? Are gyro pads I recommended here better than rubber standoffs? I feel that they are better, but I do not have any solid data to prove it. So I can only tell, that I find them better and that is all. But, I can answer the question…

  • And the most popular flight controller for INAV is…

    Did you ever wondered what is the most popular flight controller? Hardware I mean. I can tell you 🙂 OK, maybe it will not be a full truth, since I have data only from INAV, but assuming that distribution for Betaflight and Cleanflight is similar, we might know what is happening… Important, this is not…
