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).
