I build a Y-6 FPV Hexacopter

Here it is: A Y6 hexacopter build from scrap parts and a self printed TPU frame.

Pardon the build quality. I really hacked it together in a total of 4 hours. It looks like sh*t, but it flies SO GOOD!

It’s running Betaflight 3.5. The motors are just some random Racerstars – two different sizes even! 2206 on top, 2205 on the bottom. The ESCs are two 20A and 4 30A (Racerstar and Makerfire).

Create a video clip from a set of images using ffmpeg

imagine your image folder looks like this:

rephlex@hera:[~/Schreibtisch/gna]: ls -1 * | head
G0037679.JPG
G0037680.JPG
G0037681.JPG
G0037682.JPG
G0037683.JPG
G0037684.JPG
G0037685.JPG
G0037686.JPG
G0037687.JPG
G0037688.JPG

[…]

This is the command you’re looking for:

ffmpeg -framerate 25 -start_number 37679 -i G00%05d.JPG -c:v libx264 -profile:v high -crf 20 -pix_fmt yuv420p output.mp4

Ghost / unknown flying object (FPV Freestyle Double Feature)

I uploaded a new video onto the Tube, it’s called „Ghost / unknown flying object“.

I liked picking up the idea of a double feature, which is movie enthusiast slang nowadays, but used to be quite common: You pay once, and get to see two movies (two features).

It’s mainly footage from my Mallorca trip in 2018, the intro is me chasing Sean’s wing in Hallstadt, Germany. It’s not related to Mallorca, just thought to myself it makes for a good opening. Well, now that i think about it, that sesh was the last time I went flying before going on that plane, so it kinda has its place there at the beginning.

So, without further ado: Enjoy and please subscribe!

Installing Brother DCP Scanner Drivers in Ubuntu

Start a Terminal using CTRL+ALT+T. Install some depencencies and frontend scanner tools using

sudo apt-get install xsane sane-utils simple-scan lib32stdc++6

Now download the drivers. In case brother loses them, I mirrored them here. Alternatively use the wget commands down below.

wget http://download.brother.com/welcome/dlf006646/brscan4-0.4.4-4.i386.deb -O brscan4-0.4.4-4.i386.deb
wget http://download.brother.com/welcome/dlf006651/brscan-skey-0.2.4-1.i386.deb -O brscan-skey-0.2.4-1.i386.deb
wget http://download.brother.com/welcome/dlf006654/brother-udev-rule-type1-1.0.2-0.all.deb -O brother-udev-rule-type1-1.0.2-0.all.deb

Now install the drivers you just downloaded:

sudo dpkg -i –force-architecture brscan.deb brother-udev-rule.deb

And restart your udev service:

sudo systemctl restart udev.service

All i had to do was unplug and plug in my DCP, and i could immediately scan using simple-scan in Gnome.
