Dies ist ein Beitrag für den Kurzfilm-Wettbewerb in unserer Heimat-Region (Semmering-Rax). Hier habe ich versucht die schönsten Szenen "meiner" Region in 3 Minuten unter zu bringen. Das UNESCO-Weltkulturerbe - die "Semmering-Bahn" war die erste normalspurige Gebirgsbahn Europas und gibt ein wunderbares Motiv ab.
This is my contribution to a local short film contest. It's about our region here and the theme is the historic railway track in the "Semmering" region. It features shots from the last 2-3 years.
If you're really interested in the locations I can later do a video index - or just ask me in the comments.

Which one is better? ImmersionRC Duo5800 vs Black Pearl Video Diversity receiver comparison
In this comparison video I wanted to find out if the Black Pearl (all in one - Display with diversityRX) is compareable to the dedicated ImmersionRC Duo5800 receiver. On paper they both have 90dbi sensitivity. See in the second part how they look in comparison. For my test setup I seperated video TX and RX with a few thick walls at home.
Also I measured all my antennas with the ImmersionRC RF Powermeter. You see the values at 2:24.
The normal ones were affected by alignment (horz vs vert) and the SPW ones were "immune" to different alignment - as expected. The directional antennas had great antenna-gain in the cone and somewhat less optimal outside of it.

Btw. you can also measure the mW of your video TX. You plug a 30dB attenuator in between and set it in the powermeter. Great to measure the advertised milliwats vs the real output!
Sorry for this not being super scientific but it gives you an idea of the image quality.

Scary and fast Quadcopter DIVE (video cut off), Proximity Flights (Trincopter, KK2, Powerquad)
I have this "Powerquad" (aka TrinCopter) that is heavy but overpowered and fitted with 5000mah 4cell. I know now that it uses around 29amps at hover and 60amps on full throttle! That means you don't fly long with it - but fast. Long enough to reach out for some mountains ;-) (7+mins)
I wanted to dive down the "Mittagsstein" again. I already visited this, best quality video there so far would be the 2nd part of this -> VIDEO
Again I've been very nervous while flying close to those rocks so far up there and rushed down, a bit too far on the wrong side of the mountain and got behind some trees and got terrible video (and that with 120km downhill diving!).
After this I switched KK2 flightcontrol to Naza Lite + GPS - so I would have return home on emergencies. It may now be harder to get decent diving with Naza - but more security (and maybe lower pulse for me).
The other flights were a bit further in the woodlands - nice proximity there. And also the Ruins of Klamm (visited them often) were great to fly at. Last Vid shows my attempt to fly up to a very high mountain to film the huge terrestrial TV antennas up there (hiked up before and did some measurements = OK). But it was too high, I was too chicken - gave up around 80% of the distance. Liked how the cheap Gopro3 lookalike "Hawkeye" cam performed here (it was a hazy day!).

DIY Goggles - The Facebox - great and cheap FPV Goggles (alternative to Fatshark Dominator HD)
From the comments on my Fatshark Dominator HD review I see that this is a hot topic. So many questions about alternatives to the expensive and hard to get DomHDs.
One really good one is also the cheapes one with extra large picture, good quality and good comfort. I saw these first on a FPV meet (Poolnoodle Challenge) and was amazed by the clear and huge display. Pricing is around 100$, buildtime maybe 1-2h - but really easy!
If you have some questions, comments - don't hesitate! Good luck with the build and have fun!

Check out my blog post here for more details and all the pictures (which are also in the video at the end).
Short shopping-list:
1. Frame (styrofoam) from UK http://goo.gl/pikyzS
2. 5" TFT display from Dealextreme http://goo.gl/Vd419Y
3. better fresnel lens (optional) http://goo.gl/TlJlzp

5:25 Lag?
5:44 Fatshark DomHD vs DIY Goggles
8:20 Difference between DomHD and DIY Goggles
9:25 Price, Buildtips
10:07 Strap mount Tip!
12:00 Bluescreen?
15:27 Answer: Monitor or Goggles for beginners?
19:09 Buildpics (Pics also available on picasa)
►►Update: just before publishing this vid I did a 2nd testflight with the MiniQuad. The picture is really big, great to fly BUT: the blackscreen issue can be tricky/scary. So not sure yet if I'd trust this goggles for an expensive, bigger, unstabilized platform. So if you have some other safety features (second monitor for emergencies) it's ok.
Hover recommended routing it throug a DVR - this might eliminate the black/bluescreen. Or optimal: search for a similar size display without bluescreen.

Flight over riverbed, under bridge, beautiful fields of gold - Black Snapper
Mit dem Black Snapper einem trockenen Flußlauf folgen - mit Gimbal und Gopro3 - hat mir sehr gut gefallen dort! Zum Abschluß dann noch ein paar mal unter den Autobahnbrücken durch. Danach bei tollem Abendlicht die Felder entlang gleiten und dann noch Radfahrer ein Stück begleiten (in Filmreifer Kamerafahrt - hab ich zumindest probiert).
Und das alles passt super zu dem Musikstück von Kevin McLeod hier! Diesmal wurde zuerst die Musik auf die Zeitleiste gelegt und dann die Videoszenen dazu arrangiert - so ist's viel einfacher!
Flying with my Black Snapper (Brushless Gimbal, Gopro3) far along a dry (almost) riverbed and finally under 2 highway-bridges. And smoothly floating over evening fields with great sunlight, following bicycles in cinema-like cam-movement (at least I tried ;-)
Perfectly fitting to McLeods orchestral sound here! I'm really happy if I find royalty free music that fits so well to my video footage.
In fact here I first moved the sound on the timeline and composed video scenes to it - so much easier this way. ENJOY!
