Last summer I decided it would be interesting to make an orthomosaic map of an interesting piece of the bank on the snohomish river. I used my mavic mini2 and set the camera to 90 deg down, adjusted the camera setting for the light conditions and set the camera to a 2 second intervalometer. I then slowly flew in a grid pattern after checking the airmap app to make sure I had clearance to fly in the area. After I was done with the grid pattern, I captured some oblique shots of the shoreline to help fill in that area given the bushes and other obstacles lining it.Continue reading “Using DJI mini2 and PIX4D to generate orthomosaic image of a river bank”
There is a local landmark where I live, Rucker’s tomb. It was built in 1907 to house the remains of the Rucker family. I thought it would be good practice and a perfect subject to create a 3D model using Agisoft metashape. I took 79 nadir and oblique photos of the tomb using a DJI mavic 2 pro. I also captured some pictures using my handheld sony camera. I used the photos from the handheld to capture some large scene pictures to help give metashape some context while aligning the photos in 3D space. I used a raw image format, set the camera to manual with autofocus, set the aperture to 5 to minimise field of view and adjusted to iso and shutter for nice clear images with minimal noise.Continue reading “I scanned Ruckers tomb and created a 3d printable model”
I wanted to share some test flight video.
It was equipped with a 5000 mah 3 cell lipo. a 1100 kv 350 watt motor spinning a 9*7 prop. I did a 20 minute flight and burned 1007 ma.
As you can see from the video it is extremely stable while flying slow, even with a fairly large battery on board. I could have easily flown for an hour and a half with that battery.Continue reading “Techwing low and slow”
After years of flying UAVs in many different conditions. I have come to one conclusion. Laptops are no good for using as a ground station. #1 problem? sunglare. The techstation features a 10.1 inch display from Pixel Qi. What makes it so special is that it changes from […]

The techwings small size and rugged swept flying wing design naturally lead to some design challenges. Good low speed handling can be very difficult to achieve. this has a lot to do with the low aspect ratio and swept wing, leading to a large wing tip vortex as pictured here Another problem that flying wings […]
Hey everyone, I wanted to share the work I have been doing on making the wings very easy to install and remove and making the tail removable. The files are available on grabcad if you would like to print them yourself or they are available on the store.
hey everyone, So, I have been working on a few upgrade modifications that will be available in about a week. removable tail working belly/camera bay doors Plug and play, tool-less wings. No more dealing with pluging in servo wires and hunting for a screw driver. there will mating […]
Hey guys, I wanted to share my thoughts about the open source FEA/CFD package, openFoam. I have been using it as part of the free linux distribution, CAElinux 2013. I have been playing around with some of the tutorials for the past few weeks. Very interesting and cool. After familiarizing myself with the file […]
