10 channels for FlySky FS-i6 radios
This news might be not super fresh, but somehow it missed my attention. There is a good news for all owners of FlySky FS-i6 radios: there is an unofficial firmware that turns this cheap 6 channel radio into 10 channel one. Of course, there is a small catch, or even a few of them: All…

Read RC PWM signal with Arduino
Arduinos are cheap and simple development board. You can do a lot with even the simplest of them. For example build you own quadcopter and flight controller (after all MultiWii = Arduino + MPU6050). Of course, this is not as simple as one might imagine and there are few (actually a lot) obstacles that needs…

DIY FPV LC power noise filter
Both electrical motor and ESC are source of electrical noise that influences all devices connected to the same battery. This is why, very often, on airplanes or big multirotors FPV circuit is powered from separate battery. On small or medium drones this can be hard to archive: additional weight will influence both flight performance and flight time.…

How to add external compass to Flip32
In my last post I’ve showed how to disable internal MHC5883L compass on Flip32+ (10DOF) flight controller board. Now it’s time to fix what we’ve broken last time, and connect external MHC5883L compass with I2C bus. In my case I used very popular setup: u-blox NEO-6M GPS module with integrated MHC5883L compass. So you have…

How to disable compass on Flip32+
Build in HMC5883L compass/magnetometer is very nice feature of Flip32+ flight controller. Too bad it’s not always working like expected and there is a time, when one have to replace it by external device, positioned as far away from power cables as possible. I’ve encountered that specific problem two weeks ago when I’ve discovered the…

Fix buzzer on Flip32
Buying cheap from China is like a lottery. Sometimes everything is fine, sometimes is not. For example, I will never again buy super motors and pellers. This just does not work. With electronics it is slightly better. Usually it works. But sometimes, well, it does not. And this might be a case for Flip32+ multirotor flight…

Adding Bluetooth telemetry to Flip32+ and Cleanflight
When few weeks I wrote how to solve a problem of broken USB port in Flip32+ flight controller, I suggested that one of the solutions is adding a serial Bluetooth module to provide wireless connection with a bord. And telemetry. Excellent news is: this is pretty simple and cheap. What we will need: Flight controller…

Simple servo tester with Arduino
Servo tester is a useful little device that is needed specially when you do not have one. I’ve been placed in a situation like that few days ago what I was trying to connect ailerons with servos on my Depron plane and setup correct control throw. Luckily, I own a few Arduinos, so 15 minutes…

Dead Rat, wooden quadcopter, maiden flight
Last week I was, finally, able to perform a maiden flight of my DIY wooden quadcopter (here and here). I will not say it was huge success, but it was a success alright. What went like expected? Well, quite alot. First of all, it flies and has enough thrust to weight ratio to do flips…
