About Me:

I'm an ecologist by training and a post-doctoral research fellow at Harvard University.


Please tell us a bit about your UAV interest

I have a background in satellite remote sensing (both product delivery and end user). I'm interested in UAVs as cheap remote / environmental sensing platforms.

"Shipping will cost $41.50 - $61.75 depending if I can fit it in a smaller conventional box or a medium size flat rate one. Sorry, the rates are pretty crazy outside the US (hence my mention on the shipping outside the US)."

Hi everyone,I'm looking to sell my SF03 lightware laser rangefinder sensor. This was the start of a diy lidar setup which never materialized due to a lack of time after being snatched away to a new job.It has since been sitting on my shelve and I…

I finalized a new layout of my drone design. It now includes a top and bottom plate, a canopy to protect the autopilot and a platform for a GPS (if needed). It also includes legs to be attached to the current 3DR arms.In detail, the bottom plate…

koen.hufkens replied to koen.hufkens's discussion APM planner 2 deb package on Ubuntu 14.04 -- dirty fix
"Hi Edwin,
I don't have any 32-bit systems anymore, so I can't help you out with this.
In general what you do is download the original .deb file, unzip it, change the control file (replace openscenegraph80 by openscenegraph99) and run:
dpkg-deb…"

Hi all,I was annoyed by the fact that the standard debian package of the APM planner 2 does not install nicely on Ubuntu 14.04 because of the upgraded openscenegraph99 libraries (which mess up dependencies).As such I changed the control file on the…

Haven't been playing around with simulations anymore but I'll look into it again and give it a try.

Cheers,

"@Ned

I'll be in US as of next week Friday. I'm involved in tracking phenology with conventional cameras (a related topic in a way). The lab has also been experimenting with infragram based cameras, this looks promising (as it's cheaper than any…"
