Flexacopter the making of.

After creating the Arduspyder. We decided to create a real hexa. These are pictures of the making, maiden will be this weekend. Because of the purpose this frame is build for we sadly did not opt for an Arducopter but the frame will take an Ardu, Openpilot CC, Microkopter or any other hexa capable electronics.

The baseplate design in Rhinoceros

Finding the stupid MK BL-controller holes.

Testfitting the holes

Testrun upper plate.

Routing the motormounts.

Video

Mounted motor.

Proto wiredamper.

6 booms & motors

First mockup

Wiredamper study.

Easy on - off connectors tryout.

Final wirde dampers.

Buildin LED's

Batterybox with integrated damper.

Flexacopter is born.

I love red.

Mounting the wires.

Me.

Mario.

Nice picture.

Up close.

The easy on - off's

Assembly.

The dampers.

What a set.

Detail.

Green.

Testfit.

If you build a hex you got to do 6 controllers .....

The whole MK setup.

Even before maiden people believe in our design. MASS PRODUCTION

First customer frame ready for shipment.

and now? .....Tomorrow we will complete the Flexacopter build. And if all is ok saturday will be maiden day.

IS, I looked into the specs of a number of Nikon DSLR's and almost all of them use CMOS. The only ones I could find that used CCD is the D60, and low-end DSLR from 2008, and it's replacement, the D3000 from 2009. In 2010 it was replaced with the D3100 which has CMOS along with all the other high end DSLRs.

Now, the P7100 which is modern, top of the line point and shoot with capabilities close to the low end DSLR's has CCD.

I picked up a Sony WX10 point and shoot last month and have done some rudimentary testing. It has a CMOS, and it wasn't hard to avoid rolling shutter. Just some basic vibration damping was required.

I think the reason that your perception that GoPros are worse for rolling shutter is because they are so light weight, compact, and cheap, that segment of the market tends to no mount them very well. You NEED mass to stabilize the camera. DSLR's have a lot of mass all by themselves, so they naturally are less susceptible. Not to mention that anybody hanging a DSLR on an aircraft is more likely to use a proper mount with damping in the first place.

I think the perception that a GoPro or other small, cheap camera is more susceptible to jello is more about the market segment than it is the product.

I'm actually not a fan of DSLR's used in this application. I think it's the wrong tool for the job. Many high end P&S cameras can deliver comparable quality images with much easier mounting requirements.

Quick Google search for "aerial video jello DSLR" turns up lots of interesting stuff.

thanks for your research Robert,

can you post some images of the jellowed pics taken from the DSLR?
Rob_Lefebvre November 29, 2011 at 6:33am

Oh, and what these guys have done is bang-on. Suspending the battery in addition to the camera off the damped platform is exactly what everybody should be doing. That's the easiest way to make a big improvement in the image.
