waterwingz:
Thanks to you most of all. I very much appreciate that you were willing to share your experience and offer assistance.
If I can offer any help to you, or CHDK in general; I'm here for you.
One bit of off-topic, but potentially useful information for the camera-hacking crowd: I've build custom remote triggers for both Canon and Nikon before. Canon always follows the same "three pin" format, even when using the different connector for DSLR's. There's a company called Aputure in China that makes cheap remotes. The remotes are standard, just the "pigtails" are different for each company. The pigtails are a cheap way to get the connector that you need. You can either cut them, or use the 2.5mm female which they include. Canon and Nikon are trivial to wire. Canon has a proprietary "3 pin" and Nikon has a proprietary "10 pin". It's just convenient that the G10 G11 G12 use an industry standard connector.
I was building a hookup to trigger pad sensors for a haunted house. I do a lot of photo work for them, and they wanted a "roller coaster" photo type setup. It was interesting automation.
