Modified remote switch for Canon EOS 300D, 350D and 400D

I read about how to create a modified remote switch made from Motorola Head Phone from the digital photography board in Thailand. It works very well and you can do it easily.. 10 mins job : ) As I know, it works properly with Canon EOS 300D, 350D and 400D.

Let's start

1. Buy Motorola Head Phone, there are 2 black rings at a head phone jack.
2. Take the cover off and you will see a speaker phone line and head phone line.
3. Cut them off
4. Reassemble the cover
5. Here we go. When you press the button, it will automatically focus. If you press again, it will shoot a photo. If the camera already focuses, when you press the button it will shoot. It works OK and very economy (3 US$ for Motorola head set) .

I used it when I took my fireworks photos and an example is shown below. I will post "How to photograph fireworks" later and show you more firework photos : )
Cheers
Have a nice and lovely day
