A quick update...
On the weekend, using a piece of freeware called Audacity, I was able to replicate the signal that would initiate the bulb setting by IR remote control on my Pentax Km.
The only things I needed to buy were 2 IR LEDs which cost a total of $2.50 from Jaycar. I had an old audio extension cable at home which I modified with the LEDS and this cable now plugs into the earphone socket of my phone. I have 3 different wav files for 1, 2 & 5 minute exposures as well as one for a simple shutter release. I just play the corresponding wav file for the length of exposure that I require and away goes the Km, capturing all those elusive photons!!!
I tested it last night and it worked a treat. Unfortunately PHD guiding decided to play silly buggers so I have no decent images to share!!
Cheers,
Mario
