DJI Mavic Air Ultra Portable 4k Drone!

DJI Mavic Air

The new Mavic Air may actually be the drone you have been waiting for.  It has most of the technologies that have evolved on pricier drones like the Inspire series and Phantom high-end consumer offerings like obstacle avoidance, awareness sensors, and now at this tiny size, a 4k 30p 3-axis gimbal stabilized camera.  The 4k recording ups the ante at 100mbps compared to the Mavic Pro’s 60mbps which was a big issue for motion artifacts and clearly separated the quality lines on phantom and Mavic series.

The new drone also has the ability to shoot 120fps Full HD 1080p video in what looks like improved quality “but still a little noisy” which is also a plus.  The sensor is the same as on the Mavic Pro with a 1/2.3″ size at 12MP with HDR still shooting mode and an 85°-degree FOV. The main feature of course is the size which is slightly bigger than last year’s spark but with finally 4k image quality. Portability is probably the most important drone feature today. → Continue Reading Full Post ←

Schlieren Imaging Slow Motion DIY!

Schlieren Imaging Slow Motion

Sometimes all it takes to embark on a new project is some unexpected inspiration.  On the Incredible Slow Motion video by Veritasium – Seeing the Invisible: Schlieren Imaging in SLOW MOTION we are not only inspired but awestruck by the results of this simple and doable at home scientific experiment.   The experiment allows a camera to visualize the vortexes of gases and temperature differences in the air which serve to create some very interesting scientific experiments and or artistic visualizations.

You will need a Concave Parabolic Mirror like the ones used in reflective Newtonian telescopes, “you may have one lying around from your stargazing days”,  you will also need a small light source like an LED flashlight or single diode and finally a razor blade or similar precise object to cut off the light to the camera on a plane. → Continue Reading Full Post ←
