AnyFC F7 and DIY buzzer for INAV
Because both original and Banggood clone of AnyFC F7 flight controller and missing buzzer support, its usefulness is somehow limited. There is no dedicated pin and driver. Next release of INAV (1.7.2) will finally solve this problem by reusing Motor #9 output as buzzer output. But, some additional hardware will be required. To be precise,…

Omnibus F7 Flight Controller
I got my hands on a new STM32 F7 flight controller: Omnibus F7. Before we proceed, small note. I am a huge fan of F7 flight controllers. In a year, they will be a main line of high performance FC on the market. STM32F7 with built-in UART inverters solves so many issues STM32 F4 boards…

Hardware revisions of Omnibus F4 flight controllers
The Omnibus F4 series is one of my favorite flight controllers. Two of my quads are flying thanks to them. They might not be the best or the famous ones, but they get the job done. And that is what counts. Unfortunately, they are not free of faults (and what is?) and each next revision…

GPS Racer: worklog #7 – flying at night
Like promised, I took GPS Racer equipped with night vision camera RunCam Night Eagle and IR projectors for a night flight. And it worked. Not as good as I expected, but worked. RunCam Night Eagle is sensitive enough to fly at night. Just like that. As long as there is at least some light, you…

Autonomous flight, or landing, without knowledge about airspeed can easily lead to a stall. Stall can lead to crash. A crash leads to rebuild. Rebuild of big airplane is a nightmare. Although, for some…

GPS Racer: worklog #6
I have to admit, I have a talent for building ugly looking quadcopters and airplanes. But this is a step forward. This is the ugliest quadcopter I’ve ever seen… just look at it… So ugly, that almost beautiful… Those two “eyes” are IR projectors and that almost not visible FPV camera is RunCam Night Eagle……

GPS Racer: worklog #5
I’ve finally decided to make a decent use of my GPS Racer quadcopter. Until now, I mainly used it to test new things for INAV and that is more less all. RunCam Owl Plus FPV camera turned out to be non-flyable in the night, so I’ve decided to go one step further… RunCam Night Eagle…

USBasp driver for Windows 10 – Working solution
Yesterday I’ve spent like 2 hours fighting to make USBasp ISP programmer work under Windows 10 64bit. Seriously, that was like some kind of nightmare that turned into a comedy. All web pages that I’ve found suggested following procedure: Unfortunately, in my case all attempts failed miserably. All I was getting from avrdude was I’ve…
