Remote control devices

I'm thinking of making up a camera trap, to allow a IR signal to switch a relay to fire the camera and flash units...

Is it a standard 3.5mm audio jack for connection? (presumably stereo for pre release and release?)

Re: Remote control devices

It is compatible with the Canon RS-60E3.
Here is one for 5.80 - you could cut the cable to modify it.

Re: Remote control devices

The kit is an IR beam trap. I will dig it out and post some details

Graham,

Many thanks, but I need the trap to be wide enough for a bird to fly through, so I'm making up a device to trigger the camera, rather than the flash, so it can be used with or without flash as needed.

So I've bought all the bits from RS components to make up my own kit... (what can possibly go wrong?)

The only bit I'm missing is how the remote triggers the camera, I'm assuming it's a push button that makes a short between two of the stereo pins on the 3.5mm jack, with one for pre and one for actual release, however I don't have that info...

The SCR in the circuit closes (like a switch) to trigger either the camera or the flash. The SCR I used is rated to 1000V so no problem using old guns with high trigger voltages.


That company, and others, have cross beam sensors and zig-zag (off a mirror) sensors to enable you to catch very small things.


The small gap sensor shown was used for water drops and was very effective. I may just power it up and do some more...
