Explosion
Well I finally went back to try explosions again now that my system is more dialed in. the net result is that the system has better resolution but isn't as colorful. I am using the CameraAxe and as I kind of suspected, it isn't fast enough to really catch the first stages of the explosion. Microprocessors have their clock speed to deal with.
The set-up is much more usable though. I bought a sound sensor from Adafruit industries that works really well with the CameraAxe. Setting the trigger level with this set-up is wonderful easy.
Now I have to try and figure out a simple analog solution to get earlier in the event. I's like to make at least a few pictures of interacting shock waves.
This picture used a circular cut-off that has 2D sensitivity. Also check out the repeatability between the two events. Better than it should be.
Cheers.
