You should be able to do this with a photodiode and script control of one of the LEDs on the powershot.

Cool, so I already own an IXUS50, I also have the cable release for the 5D.  Now all I need is some developer brainpower!  What else do I need and how am I going to make it work?  Thanks all for the assistance to date.  Eventually the manufacturers will surely include this sort of functionality...

What kind of motion detection do you need? Are you doing light detection or human motion or what?

One cheap solution would be getting a PIR and plugging it into the 2.5mm jack (I thought 5D used N3? ...). Cost would be $10-15 and would detect humans and animals. Put in a timer circuit with a pot and you could have it hit your shutter button on an adjustable delay.

Well, I'd love to get it all.  However, let's keep the scope narrow initially.  Primary motivation would be to capture fast moving action.  Specifically mountain bikers going over a jump.  Secondly, would be nice to capture lightning strikes.

You are correct, the 5D has the N3 connector.

A PIR may well do part of the trick.  What sort of response times can you get (ie. are they fast enough)?  Any recommendations for a portable unit?

Thanks again.

For mountain bikers I suggest you shoot burst mode while panning :) The advantages of using a DSLR are fast composition, fast focus and high burst speed. Especially with the 5D.
For lightning strikes I don't think a PIR detector will work. It will work with the bikers though, it is fast enough. Most PIR sensors are portable (alarm type).
There are motion-activated halogen lights also, but you'd have to hack your way through to dismount the sensor.

Hi,

Did anyone made any progress on this camera ?

I'd love to have an intervalometer on my 5D. I have some time to spend on that but don't know where to start ...

Hi,
 I have a 5D and I'm a software developer.
Is there anyone interested in this camera?

Did you install Magic Lantern on it? It seems a very good starting point for porting CHDK.

Check the Magic Lantern wiki www.magiclantern.wikia.com, AJ's reverse engineering efforts at http://magiclantern.wikia.com/wiki/2.0.4_AJ and join the development team!

Thanks a1ex, but I have a 5d Mark I, so I think that magiclantern firmware is not suitable.

Sorry, you are right. 5D has a Digic II processor and runs VxWorks.

Can you run Canon Basic scripts on the camera? I've tried to run them on 550D, with no success...

No, I haven't read how to do it.
I have disassembled firmware 1.1.1 and I'm isolating the strings inside...that's the easiest part.
