  • FS1000A and XY-MK-5V range test

    Very often, where you go cheap, there is a price to pay. Exactly like with cheap 433MHz transmitter-receiver pair of FS1000A and XY-MK-5V. You rather do not expect much for $1, right? When playing with them in a middle of a big city (Berlin), few meters of the range was all those modules were able…

  • INAV can do automated landing on fixed wing?

    Those of you how subscribed to my YouTube channel should have noticed, that I got an interest in automated landing of fixed wings after RTH in INAV. And the sad truth was that, well, INAV up to 1.7 was unable to do it right. When landing after RTH was enabled (nav_rth_allow_landing = ON) and it…

  • FS1000A and XY-MK-5V 433MHz RF modules: overview

    One of the cheapest (but not the best) solutions for DIY wireless data transmission between different devices (Arduino and other microcontrollers) is a pair of 433MHz modules: FS1000A and XY-MK-5V. A set of them (you will need one transmitter and one receiver) costs about $1. Pretty cheap, right? Of course, there is a price to…

  • AnyFC F7 output mapping for INAV

    AnyFC F7 when running INAV, is not using standard output mapping. That means, that M1 output is not where you should connect Motor 1 and M2 is not where Motor 2 should be connected. It’s a little complicated, but with following table it should be pretty easy to connect any possible configuration to AnyFC F7…

  • Using FET transistors as switches

    When over a year ago I published this post about using transistors as switches, I described only how to do it with bipolar transistors. And bipolar (NPN and PNP) transistors have a small problem: they are current driven, so they consume current when they are switched on. They consume much less than they drive, but…

  • AnyFC F7 Pinout

    There is still very little about AnyFC F7 on the internet. Especially pinout is kept secret. Without sambas official GitHub repository for hardware projects, there would be nothing at all. I’ve decided to close that gap a little and prepared full pinout for AnyFCF7. Yes, I know they are hand drawn and scanned, but I…

  • FrSky SmartPort Telemetry on AnyFC F7

    STM32F7 CPU family present in newest, experimental, flight controllers like AnyFC F7 (as well as upcoming AnyFC M7 with smaller STM32F722) simplifies many things. For example, comparing to F4 boards, SmartPort or S.Bus connection is extremely simple and can be done on any free UART. No more hardware hacks, external inverters and other “special” ways…

  • Hands on: AnyFC F7 from Banggood

    Before we proceed, short clarification. Legal background of AnyFC F7 flight controller from Banggood is iffy. It’s not that BG ripped the design from Sami Korhonen (sambas). Sambas published design of his AnyFC under Creative Commons BY-SA. So, it’s free to copy this design as long as Sambas is referenced as author, and license is…

  • GPS Racer: worklog #4

    Yesterday I finally maidened my GPS Racer in full FPV configuration. RunCam Owl Plus and VTX finally arrived, it was not raining, so I took recording gear after sunset and went flying. To be precise, it was not “night”. But it was pretty dark. Too dark for my RunCam Swift. Owl Plus was sensitive enough…
