TPB #91 – Bullets Colliding with Water Droplets

Posted by:

The holy grail of high speed photography. A shot of mythical technical expertise where a pellet pierces a water droplet in midair. Here I demystify this incredible shot and give the complete details on how anyone with a Camera Axe can recreate this amazing shot!

Here is the Camera Axe software I used in the video.

TPB #90 – Analyzing Error in the Projectile Sensor

Posted by:

The error of the Camera Axe’s projectile sensor is analyzed. Experiments are done in software to isolate the error which turns out to come almost entirely from the 4 microsecond granularity of the Camera Axe’s timer hardware. Then math is done on that 4 microsecond granularity to determine how that affects the reported speed of the bullet in the Camera Axe and the positioning of the bullet in a photo.

For a ...

TPB #74 – Air Cannon

Posted by:

In this video I describe how to take photos of flying ball bearings shot from an air cannon. I also go over the different energies in this versus an air pellet, and how that kinetic energy gets distributed into the target.

UPDATE: Alan pointed out my energy calculations were off by a few orders of magnitude and wikipedia confirmed it (http://en.wikipedia.org/wiki/Joule). The units for Joules are kg*(m^2)*(s^2). My units were g*(m^2)*(s^2). So to ...
