This should be easy..

Hello All..
Can anyone guide me.. help me to find.. help me build.. maybe build for me.. send it free of charge.. and maybe even throw a couple bucks in the package so I can..

Seriously.. I need some kind of circut/timer that when actuated by a momentary short/close like the push of a button stays on/closed for a certain duration.. like 1-2 seconds.

I have a intervalometer that triggers my camera every $.. its just a momentary close that triggers my shutter.. i need somthing that will take that signal and output a longer adjustable close/short time. does this make any sense ?

isnt it some kind of micro timer/relay I can make ? or as I said before maybe one of you guys could build for me and your wife or girlfriend could deliver to my door along with dinner...

Sorry for the jokes.. I thought if I could get a laugh.. I'd get an answer.. thanks for looking !

Yes, it can be done using the 555 timer and is fairly straightforward.

It depends on how the camera interfaces with the switch. The easiest option is just to use a relay but it's not always the most efficient.

like a normal mechanical cable release It simply closes as long as i hold it. where to get plans for my specific need of this circut..? or is it prebuilt that I can buy it ?

again I just need it to when triggered/closed on the input gives a closed output for 1 to 3 seconds.. preferably adjustable. but even if a more simple circut.. I could build a few with different length outputs
