In this video I over using a flash hotshoe with the Camera Axe and and connecting it to small tabletop tripod.

In this episode I go over a some small changes to the Camera Axe 5. The power system has been updated to improve reliability. The Camera Axe now has a panel on the back to install AA batteries. This makes it easy to swap out batteries in the field if it runs out of charge and the battery life is now longer.
You can get the Camera Axe in the store.

This video goes over the Flash Test Menu and finds why it hasn’t been reporting correct flash durations. The problem turned out to be the light sensor being used is not fast enough. To make this mode work reliably we’ll need a new light sensor that quickly transitions from <1V to >4V. I estimate a responce time of less then 5 us would be good for standard flashes and less than 0.1 ...Continue Reading →
In this video I talk about the new software features in the Camera Axe 5.4 beta2 software. The new features are:
* Option to select whether camera/flash1 is a camera or a flash in the valve menu
* Bulb ramping (bramping) added to the intervalometer
* New fireworks menu added to help take photos of fireworks
* New flashtest menu to measure the lag and duration of flashes and cameras
* CA 5.4 ...
In this week’s video I talk about the battery life on the Camera Axe 5. With the backlight on you will get about 12 hours of use and with the backlight off you will get 24 hours of use. Then I discuss various options on how to increase the battery life.Continue Reading →
In this week’s video I look into the new features in the just released Camera Axe 5.3 software. There are a lot of interesting features here.

* Changed file types from *.pde to *.ino as recommended for Arduino 1.0
* Updated code ...
This week I am sharing some work from Guy Viner where he brings together a group of photographers to create a bullet time effect. The brilliance in this idea is you don’t need to buy a bunch of cameras since all your friends are bringing their cameras. This video goes through how he setup his shots. He was using the Camera Axe to help time his flashes.
Thanks to Guy Viner for ...Continue Reading →
This week I describe how the Camera Axe will be using a faster analog read mechanism in future releases. This new method sacrifices some precision for 8 times faster read. After including the overhead in the Camera Axe software the overall improvement is about 2.5x. This puts analog read performance much closer to digital read performance.
A huge thanks to gvi70000 on the Camera Axe forums who suggested this change.
You can get beta ...Continue Reading →
In this episode I talk about the new digital read feature in Camera Axe software that significantly reduces lag introduced with the Camera Axe.
The old method of analog reads took around 220 us and the new digital reads take around 70 us. Both of those are fast enough for most use cases, but the digital reads might help in certain cases.
You can get the new beta Camera Axe software with these changes here.Continue Reading →
