All good stuff, thanks for all the input. I think I can figure something out from all this. I do need something remote that I can bring to the geckos, but their cage is only 8 ft away from me right now, so I may be able to connect directly to the PC. My sound card is a bloody dinosaur and the processor could be outpaced by glacier, so I may run into trouble there.
Thanks for the help, I'll post a link when I get the goods on tape
Revenge is a dish best served cold...
With a side plate of steaming entrails,
And a nice Bordeaux!
