Robot vs. Tiger

Posted on July 2, 2014 at 7:44am 4 Comments

I ran into this on Youtube and thought, I'd share it. For once, it's no flying thing for a change and second, I think, among all this politics and regulation stuff which recently dominates this site, it would be nice to see some really cool (and cute) usage of robots again.

Development of NDVI postprocessing plugin for frei0r / the MLT framework - video test footage needed!

Video: IR video postprocessing

Posted on June 14, 2014 at 6:37pm 2 Comments

For a few dollars you can buy replacement lenses without IR cut filter for popular FPV cameras and also IR passthrough filters from eBay. Additionally, many digital cameras can be modified for IR recording by simply removing the IR cut filter from the sensor. As a result you get very pinkish footage.

I have written about the postprocessing of IR…

Flexible 3D-printing filament

Posted on May 16, 2014 at 8:36am 8 Comments

As there's surely a relation between the maker scene and the UAV scene, I thought that might be interesting.

Fenner Drives came out with pretty tough but flexible TEP filament for 3D-printing a couple of months ago. I can imagine a ton of applications for this stuff in UAVs, like anti-vibration mounts or protective shells for autopilots, cameras,…
