Title: Using the Jack port
Post by Hanspi on 08/11/10 at 21:57:26
Hello,

After some researchs online on how to us one of my portable consol (psp or NDS) as a camera controller. I would like to know if it is possible to use the consol jack port to remotly control the camera?

Insteed of using the GBA slot and adding electronic between the consol and the camera, it will be nice to directly plug a jack cable between the two device. (n3 plug is almost a jack plug...). This could be nice but since no one seems to speak about it, I guess it is not possible...


the NDS (and the psp) has abilities to send (audio) signal throw the jack port.

tl;dr : Is it possible to use the NDS jack port to trigger the camera?

Thank you.

(and sorry for my english).

Hans

i think it could probably be done. but not with one wire. there may have to be something inbetween.

I think this Iphone app could be an inspiration: http://www.nin9lives.com/timeFugit

I wish my iPhone would work for more than five minutes. In any case, a simple loud sound can be used to make a relay close. The device you linked to doesn't try to control shot length, it's all up to the camera. That's sorta not as useful.

So you think it is possible?
For example using the stereo capabilities of the nds, a loud nose to the right may correspond to a half-pressed button and a loud nose to the left to a full-pressed button? (or inversment...).

I don't think it is that simple, sending a sound throught the jack port is actually "sending current" inside the camera...  and i don't think it is a good thing!

to be continued...

plug your camera into a mp3 player, see if it pops off....

dslrs can withstand upto a 6v pulse, thats what the flashes pop off at. old SLR not digital ones can withstand 12v

Oh, lordy no! I mentioned a relay, an intermediate device to protect your camera. Do not plug audio into your DSLR.

Be assured that I never had the intention to plug any mp3 device!! :D

I guess it was a too simple idea to be possible. too bad.

Sorry to bother you once again with my dead-end idea...
but I am a little bit narrow-minded and I found this :
http://www.instructables.com/id/Turn-a-TI-Graphing-Calculator-into-an-Intervalomet/

I guess that if a calculator can do it, a ds or a psp can do it too...

Once again, what do you think of this solution? Is it possible?

I promise, this time, that if one of you tells me one more time that it is impossible, I will hide myself in a deep deep forest and you will never heard of me (and of my stupid idea) again!  :-X

buy a cable for the ds, it can be used as an intervalometer.
