depends.
you need to be able to send correct Trigger code from your RI universal remote.
The device & application is very simple
It just send pulses in audio form to the head phone jack. Instead of driving the audio transducer to make sound, it turns the IR transmitter on/off (pulses).
Correct code (in pulse interval, pulse width) will be needed.
If you know the trigger code, it will not be too difficult to program an application to output sound to audio jack.
I Was thinking of working on Andriod version.
You basically can program a simple to full function Interval timer using Andriod APPs Dev Kit, interface to a simple IR transmitter via phone jack.
ah..then there is this application already.. by Bitshift. ..Search "DSLR Remote" in Andriod PLAY Store. You can make your own Jack to IR Transmitter cheaply.
No need to spend money to buy expensive Interval-timer.
