[How to] CJMCU-MEGA 2560, sensors and Multiwii: The Complete Guide

The Complete Guide to run the Multiwii software on the CJMCU-MEGA 2560 with custom sensors. A.k.a.  Arduino Mega 2560 ATmega2560-16AU This board is nothing else than an Arduino Mega 2560 with a reviewed layout, in order to be mount friendly and to have a reduced size. This is very similar to the CRIUS AIO which, as its own name suggests, has a 9DOF sensors onboard, Read More →

Mini flight controller AEORC v0.1 – How To add a Barometer BMP085

This post is part of a complete guide to this the Mini flight controller AEORC. So i wanted to upgrade my Multiwii Quad, since i have some spare bosh bmp085 (digital barometric pressure sensor) to test and the I2C port is completelly free on my Multiwii Board, i will add this barometer i2c imu. This baro is already soldered on an IMU, so no need to Read More →

Multiwii Configuration: BASIC SETUP

BASIC SETUP The type of multicopter: GIMBAL: this is used just to pilot a two servo camera gymbal, This is used to add camera stabilization capabilities to an already existant platform BI: this is used for a non very common aircraft platform: the bicopter, a dual tilting motor. The Bicopter stability (especially in pitch) is its weak point having just two motors. Each motor is Read More →

Quadcopter how to reduce vibrations:prop spinners VS prop savers

This is how i achieve a little more stability reducing vibrations coming from motors using prop savers. First of all: I’m using old, not-so-balanced and not to smooth motors: Wich better test field for this very purpose? an exasperatelly unstable test platform can actually demonstrate if I’m right much better than a already stable platform where, probably, our improvement would be less perceptible that on Read More →

L3G4200D Caracteristics, features, circuit schematics and datasheet

I decided to dedicate a POST to the L3G4200D gyro. This popular and low cost sensor is present on a number of multirotors IMU out there. In my case i’ve found this sensor on both models of wich is defined as GY-80 also known as “10DOF 9-axis“, a value for price imu, easy enough except for the pullup resistor needed by this imu in order Read More →
