Hello again,

Since my last post i was a little bit busy, but these days i had the time to finish my EOS 450D wire remote control. I've made a few tests and is working fine...however i have the feeling that i miss something . Please have a look here http://www.grozeaion.com/high-speed-photography.html and send me yours observations regarding these circuits.

Thank you!

 

what function do you require that isn't being performed by the circuit?

I apply remote triggering and various other camera commands, but via the USB port. This doesn't have the speed, but has other advantages. I use a variety of triggers as well as stacked storage, pannng drives, etc.

 

As i said the circuits works, but as i am a beginner i have the feeling that i forgot something in the light dark trigger

 

i've start to build the third version of the remote, this time the pcb is no longer made by me

here i post some pictures
