The aim of this project is to achieve better quality photos that doesn't appear moved in low light environment.
To do this I have synchronized the trigger of a xenon flash with the picture taking. This reduces the exposure and allows that the picture is taken faster.
The complexity of this project is basically:
- Synchronize the trigger of the xenon flash and the picture taking.
- Elevator circuit from 5V to 300V required for the xenon flash.
Here is the result:
And here is the schematic:
As you can see, it is composed of:
- A phodiode to detect the led activation.
- An elevator circuit to achieve the voltage requirement.
- And a microcontroller to control the charge and the trigger.
Finally, here is the presentation about the project. If you have some question don't hesitate to ask here or in the forum.
