My XJ470 rebuilt

best viewed with 720p HD settingsThis winter I rebuilt my XJ470: added a PiZero with a Picam. This PiZero functions as a companion computer with a python dronekit and a WiFi access point enabling a mavlinkbridge. Hence an android tablet, running Tower, can be connected to this WiFi access point for monitoring and telemetry. Moreover the PiZero-Picam streams video from the multicopter. This new configuration was successfully tested at the Model Club de la Côte de Beauté (MCCB) Charente Maritime…See More

testflight xj470

For bench marking my own developed flight controller, I built a Quanum XJ470 drone with a DroPix (Arducopter/PixHawk) flight controller. Some additional features: esc AFRO 30A; motors: SunnySky 980 KV; props 10 x 4.5. My first testflight shows that the drone with the DroPix flies great.See More

"If k->1 the accelerometer becomes more dominant, the rise time decreases (faster system) but the steady state error due to the accelerometer offset increases. Offset drifts over time and is temperature dependent. As a compromise I limited k to…"

comment on complementary filtering

Complementary filters enable sensor fusion, are easy to implement and eliminate integrating errors from gyro’s or accelerometers. Normally complementary filters are discussed in the frequency domain.  Using simple Python code a 1st order linear complementary filter for determining the quadcopter ground speed was analyzed in…See More

FPV testflight 3D printed crossfire

I upgraded my 3D printed crossfire with a Boscam transmitter TS351 and a all-in-one monitor RX-LCD5802. The FPV camera is a GoPro Hero 3. Simultaneously a Sparkfun GPS LS23060 was added. This implied adding code for reading, parsing and processing nmea data. I have chosen a complementary filter approach for fusion of accelerometer data and GPS data. I managed to implement the additional code in my DIY flight controller with a 8 bit PSoC 3 from Cypress running at 45 MHz. In order to minimize the…See More

Test-flights of my 3D printed quadcopters

After tuning my PID parameters for both my 3D printed quadcopters crossfire and miniflame, I succeeded in having some decent test-flights. The flight controller used is an own built controller inspired by KK2, AeroQuad and ArduCopter. Future development: including a GPS module.See More

"If you ever want to join the dev group and help us push arducopter & arduplane forward we're on drones-discuss@googlegroups.com.  No pressure though.  Everybody's got their own reasons for working on things."

Profile Information

About Me:
Retired prof. in (micro)electronics
Please tell us a bit about your UAV interest
Like building, designing electronic sensor modules. Today's project is designing and building a quadcopter.
Hometown:
Gent, Belgium

1st quadcopter

I bought an Frsky DF 2.4Ghz Combo Pack and dismantled the transmitter package and built my own transmitter as shown.

Apart from the DFT 8-channel  transmitter,  the RC Tx/Rx unit has an own built board with 2 psoc1 mcu’s from Cypress for generating the ppm signal, reading the sticks position and  BT pc communication.

Milling of pcb

A python program controls the settings of the RC Tx/Rx unit and displays the telemetry data

The different parts of the quadcopter are milled in plastic and aluminum. The flightcontroller is the wellknown KK2.0.

Testflights were successful and I gained a lot of experience from this 1st quadcopter.
