Here I am.
My main concern is being able to get the pictures on my pc after shooting, i could live along with manual shooting and the usual feast of wires. If all the bells and whistles Gregg is offering will come in a nicely packaged cheap cutie of this kind count me in for one unit (pink please).
The only question is now: which camera model will support the data transfer ?
Thanks for the supa fast response guys.

.
if you are concerned about the safety of your camera.

Gregg, an unregulated 6V is just fine.

The USB specification is irrelevant, the USB V+ on these cameras is actually a logic input to the DIGIC processor via some level-shifting transistors.

Typically, the switch voltage drives the base of the first transistor via a resistor in the tens of kilohms range.

Measure the resistance across the two outer connections to see what the value is on your camera.

Swap the leads over and check again.

Hi Simone
Yes what Gregg is doing is a "nicely packaged cheap cutie".
Sounds like the perfect boyfriend !
Gregg has something new up his sleeve & he hasn't told us the full story yet ?
I will be off with the sandman soon, so I may not be much help for longer.
It is in the middle of winter here in Australia :-)

Frans,

Mine is really not too different than those except for those are non-regulated voltage sources. From the picture it looks as though it uses 4 x 1.5v cells. That is an unregulated 6vdc. Not entirely safe for the camera. I've heard that some cameras are more sensitive than others, but not sure which ones are which. I'm not going to risk my cameras to 6vdc unregulated.
Mine is a regulated 4.2vdc which is totally safe for any camera that I'm aware of.
Besides mine uses the same USB cable as you would use for copying your photos off the camera to your PC. This saves on the amount of hardware you need to carry with you.
Mine also allows you to plug in a wireless remote control so you may break away from the cord and trigger your camera up to 300 + feet away.
And besides mine will only cost a few dollars more (for those that chose to buy than build). If you have built your own and you are happy with the results, then I am probably not going to sell you one of mine. But if you are concerned about the safety of your camera and wish to have an RF wireless remote then maybe you'd be interested in what I'm going to be producing.

Best regards,
Gregg

Hi Gregg,

No, I will not be buying one from you as essentially what you are making, is a remote like I made for Jan Martin's Do It Yourself Streetview Project. This is the remote Versatile (wireless) SDM remote and this is the site of his project: http://www.diy-streetview.org/

David already explained why it is perfectly safe to use 6 volts for a remote but this version is working on 4.5 volts.
It is of course not so small as the one you will be making because there was no requirement for it to be small but with the use of button cells and female connectors instead of the fixed cables, it could indeed be as small us a USB thumb drive.

Hi Gregg
I have looked at the Canon style remotes, but I can't see any with the 2.5 mm plugs ??
Are these male or female ?
Can you see any on e-bay or somewhere to show me what is needed, Please ?
The ones I have seen in Aust are around $100 plus.
Cheers

Well, I am not Gregg but here is one for example:

Thanks Frans
That looks like what I need to buy.
Looks well made too.
I had seen others with different ends, some even with 3.5 mm, which I thought was a mistake.

Yes, I have one of those and they are well made and work perfectly.
The nice thing is that you can still use the receiver part as a wired remote in case the battery lost power.

I have not had a chance to post the pictures since I've gone through a redesign of the product due to pre-mature battery depletion. The LED was drawing to much current. I'm looking at either a different battery source or dropping the LED indicator. TBD. I'll get back when I've redesigned the circuit. Incidentally I used the remote sucessfully duing my photo session from the 4th of July. It simply worked great (except for the battery depletion issue).
