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…

Pitot tube is coming to INAV
One of the things that INAV was missing, was a decent support for Pitot tubes, or more generally speaking, airspeed sensors. 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…

Depron Airboat Worklog #2
Next week passed and Depron Airboat is almost ready. Almost, since it still needs some finishing and I’m missing a BEC. Turned out that total power usage of one 9g servo and FrSky X4R receiver is slightly too high to just use single LM7805. 350mA during servo movement means more that 2W of heat ((12-5)…

AnyFC F7 and a missing baro problem
When Banggood decided to “forget” about MS5611barometer in their version of AnyFC F7 flight controller, they not only did not mounted MS5611 on it. They also made usage of any external barometer on that board almost impossible to use. Why? Long story short: all STM32 MultiWii derivatives are unable (yet) to lookup for I2C devices…

Hands on: DemonRC NOX5 FPV 5" Frame
So many things to do, so little time… I’ve purchased DemonRC NOX5 quadcopter frame more than a month ago, but had some time to take a look at it only today. This is not a cheap stuff. More than a $100 for a 5″ frame is few times more than I’ve used to pay. But…
