Camera Project Back In Focus

Regarding Michael Wieckowski’s July 2013 article: One of the projects on my list is a control for my camera; in particular, a motion sensing trigger to capture animals at night. I already have a cable release and an intervalometer — the first mainly to have a connector that fits the camera body.

So, I read Michael’s article with interest, and measured my camera's shutter properties including which wire was which. I'm glad he introduced me to BlueGiga and the TI regulator. I'm using a similar part from Microchip (the MCP1640D).
