PWM, OneShot125 and Brushed motor protocol on an oscilloscope
When I’ve buoght an oscilloscope (cheap digital DSO201), I’ve decided it would be a good idea to see how different ESC protocols looks like from the signal point of view. Previously I’ve written few words about them, like which is the fastest as so on, but is there something “special” about them? Well, let’s find…

Project Dualcopter – worklog #2
3 weeks after my first post on Project Dualcopter, it's time for small update. The plan was to install servos and control surfaces. Instead, I've done: Basic electrical wiring for motors and ESCs. They have power now and are ready to be connected to flight controller To level shelf (above propellers) designed to hold flight…

ATtiny85 Light Sensor – I2C slave device
I love AVR ATtinyx5 series microcontrollers. They are cheap, easy to use, they can be programmed just like Arduinos and comparing to their size they offer great features. For example, they can be used as a remote analog to digital converters connected to a master device using an I2C bus. Background: A few years ago…

JJPRO P175: maiden FPV flight
Since weather in Central Europe is rather typical for this time of year (rain, wind, wind and rain), I was unable to get any decent video footage from JJPRO P175 quadcopter yet. Instead of that, here are few minutes of video from maiden FPV flight: It is fast!

OK, one can use virtual machine and some people succeeded to run it using WINE (I failed) but those are not good solutions.…

3D Printed 35deg camera stand for Runcam HD / Mobius
I have no idea how I was able to build drones before I've bought my 3D printer… I before I've learned basics of 3D design. So, today I present you upgraded version of my Runcam HD / Mobius camera mount I've designed few months ago. Changes: tilt angle increased from 25 to 35 degrees allows…

Flip32 F4 / Airbot F4 : Pinout
There is very little reliable information about Flip32 F4 / Airbot F4 on the internet, so I’ve decided to fix it. Today, pinout map for Flip32 F4 (Betaflight 3.0.1) and some additional notes: Betaflight 3: use REVO target UART1 is only UART with inverters, so S.BUS can be connected only here S.BUS / PPM pin…
