Camera Control Box
Project purpose: To create a 9v battery device to plug into my Canon Rebel digital camera's remote port that will allow me to take
pictures in a variety of ways 1) with a wireless remote control 2) Time Lapse 3) triggered by motion sensor 4) triggered by photo cell/laser
The device will have two buttons. One button to move through the four modes and the other button to select the mode.
I explain the project out in this video I had already put up: http://www.youtube.com/watch?v=90qQb9NTVjc
This new video mainly involves the mechanics of getting the buttons added.

A box like this has been on my list for a while. Hopefully, your success can lead to some motivation for me to get moving on it!
Thank you for taking the time to document the process and provide code (and soon to be coming partial schematics?)
Well done!
Just used the basic set-up for the propeller and power supply minus a reset button.
The motion sensor is an EPIR. There were some pins on it I did not use as explained in it's attached picture
The RF remote I got off ebay. RF controller
Nice time delay sequence! Long enough to get the exposure but not long enough to start seeing trails.
How did you piece the single frames together into a movie?
I was hoping to get the Milky Way, but my lack of astronomy background had me pointing to the wrong part of the sky (north). If I had thought about it, the solar system
rotates on about the same plane as the galaxy so I should have been pointing east or west. Still don't know if I can get pictures of the milky way with my camera
here in Florida with light pollution, but going to try again.
That's still a great picture. Man, I've got to build one of these.
Regardless of the outcome, this is a great project. Thank you for sharing!
