In this video I show how to use “Startup Mode” in the general settings menu to turn on the Camera Axe with the USB port. This allows external timers and even wifi outlets which can control the Camera Axe over the internet.Continue Reading →
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.Continue Reading →
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 ...Continue Reading →
This video shows a work in progress of some great software that Dan and PTB have been working on to improve the ability of the Camera Axe to photograph lightning. While the Camera Axe was already pretty good at photographing lightning this makes a number of significant improvements to that software. I encourage others to join the forum thread below and help design the best possible software update to photograph lightning. Some ...Continue Reading →
This video shows how to adjust the the brightness of the airgap flash by adjusting its internal voltage. Make sure you know how to safely handle high voltage before attempting this.Continue Reading →
I show how to make a weather proof motion sensor for the Camera Axe. Most of the video is about how the case is made, but I also touch on the fact that this sensor is more accurate than the standard Camera Axe motion sensor because it uses I2C instead of analog values to report distance.
Code (5.5 or newer an you must enable max sonar menu)
I show how to use a few dollars in parts from your local hardware store to improve a laser trigger on the Camera Axe. I basically use some PVC parts to create mounts for the laser and light sensors. This makes them weather proof, easy to mount on a tripod, and easier to align due to a diffuser in front of the light sensor. http://www.cameraaxe.comContinue Reading →
The airgap flash works well up close, but it would be nice if the light was more focused so it could be placed further from the target. Here I use laser cut acrylic pieces to build a reflector for the airgap flash and then test its performance.Continue Reading →
This video shows how to use two valve sensors with the Camera Axe to collide different colored droplets. In my searching few people have accomplished this advanced droplet technique. This video takes you step by step through the process of capturing these impressive shots.
