Canon 450D Remote Control

Finally,
After a lot of work (remember, I'm a beginner), a few burned parts and also a pcb I've got this circuit working...I know that is room for improvement so i wait yours suggestions.

I want to THANK BrownOut, mneary(www.electro-tech-online.com) and Audioguru (www.edaboard.com) for the help he provided to me

From tomorrow i will start to test it on my camera to see what are the results.


Thanks again and i will wait yours suggestions

I see its for a Camera DSLR, a very good camera indeed. What is the remote control though? What is it for? I see it has sound and light sensors on it.

it has 3 1/2 functions

1. Normal functions like on the camera shutter button, except the bulk that is no longer limited to 30s or "keep your finger on the button" for longer exposures - no camera shake.
2. Sound trigger - the shutter is trigger when a sound is pick up by microphone
3'. The shutter is trigger by light (lightning for example)
3''. The shutter is trigger by dark (when a beam of light is interrupted)

2 and 3 have sensitivity adjustment.

I'm still not satisfied with the sensitivity of the circuit
Can anyone suggest me how to increase it?
I need to trigger at the sound of a water drop in a glass
