Video overload

The Canon T4I has been busy.

Marcy 1 70fps cam (2 min 27 sec)


Marcy 1 slow motion (1 min 33 sec)


Marcy 1 fisheye slow motion (2 min 4 sec)


It began with the 1st flight using the 70fps 320x240 board cam. It wasn't tuned & oscillated. The next 2 videos had slow motion after tuning. The velocity measurement needs to be at least 7Hz before the oscillation becomes bearable.

Looking up from below in slow motion gives the impression of a long gone vehicle, but the reality is she's never been more than a week from being flyable, since 2011. There are plenty of other vehicles which will never fly again. With the flight software now working on raspberry pi, there is every intention of having a self contained flying system that always works.

The current vehicle was mostly developed in April, 2011. Only the takeoff stand was improved in Jan 2012. The machine vision system saw development in Summer 2011, Jan 2012, & the last week with conversion to a board cam.

Since monocopter development began, in 2010, there has never been an onboard camera. The plan is now to stick a basic 320x240 wifi camera board on her, in addition to the existing flight computer board & ESC. The previous plan was to replace the flight computer with the camera board & have all data on wifi, but the camera board needed to be more modular. Wifi will now just carry video & somehow automatically associate with the raspberry pi access point.
