    Diatone Hey Tina Whoop162 with FalcoX

    I will be very frank with you: I do not like those tiny whoops. You know, 2″ and smaller propellers, plastic frame, a camera on top. You know, those almost cheapest FPV drones you can get. I’m saying that builds like BetaFPV 65X or Emax Tinyhawk are bad. I just do not like to fly…

  • Generate S.Bus with Arduino in a simple way

    Generate S.Bus with Arduino in a simple way

    Did you noticed that lately I write about radios quite often? Well, I do and it’s not a coincidence. Proper introduction for what I’m working on will happen in a next few days, but now I will only write that this will be a mid-range, cheap, DIY radio link for UAVs. By mid-range I mean…

  • Simplest hardware inverter for flight controller

    Simplest hardware inverter for flight controller

    Together with increasing popularity of STM32F4 flight controllers, telemetry became hard topic again. Why? Most popular telemetry protocols, SmartPort and FrSky telemetry , requires inverted signal. Zero becomes one, one becomes zero. In case on STM32F3 that was not a big problem. Those CPUs have built in inverters. STM32F1 and STM32F4 does not. So, if…

  • MPU6000 vs MPU6050 vs MPU6500

    MPU6000 and MPU6050 Deep down, MPU6000 and MPU6050 are the same same hardware. They both have the same 3 axis gyroscope and the same 3 axis accelerometer. Both allows max 8kHz gyro sampling rate. From a flight controllers point of view, the only difference between them is bus that connects them to CPU. MPU6000 allows…

  • Generate PPM signal with Arduino

    Generate PPM signal with Arduino

    In the beginning of this year I’ve written a short tutorial how to read PWM signals from RC radio with Arduino. While it is can be useful when building own RC equipment, it does not help much when one has to deal with PPM (CPPM) signal. Let’s be honest, PPM is much more useful than…

  • Adding GPS to Flip32+ and Cleanflight

    Flip32 and Flip32+ (10 DOF version of Flip32 with built-in barometer and magnetometer) are nice little flight controllers. And cheap. Some call them clones of Naze32, but this is not completely true. Yes, they are very similar, share the same hardware, but they are not identical. I would say they are better than Naze32 since have…
