Hi,
I'm working on a project where I have to take a picture every 30s with a canon 7d.
For that purpose, I need to have a small device that will generate a beep every 30s to warn the photographer.
This device will be attached to the camera using a tape. It must be of a small size[/B, as cheap as possible and generating a Beep as loud as possible.
Do you guys have any idea on how to do to that? I would like to buy the components online and build this device. I guess this will involve a piazzo and a microcontroler.
Thank you for your help!
