My XJ470 rebuilt

best viewed with 720p HD settings

This 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…

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.

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…

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…

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.

2nd (3d printed) quadcopter

Having a background in electronics I wanted to build my own flightcontroller. At the same time I decided to build a new quadcopter. Having bought a 3d printer from Ultimaker, I printed a quadcopter frame inspired on the original Crossfire design from MickeyB (…
