Notes

What do we want the camera to do?

  • Microcontroller controlled power
  • Manual switch power
  • Own microcontroller
  • Isolated power supply or main power supply
  • Switching regulator versus linear regulator

Problem

  • Need to turn on camera and take pictures

Possible solutions

  • Tie into the main microcontroller - take points of interest (and know when picture taken)
  • Separate - simpler!
  • Free/PIC/555 Timer

Solution chosen:

  • 555 Timer with battery pack. Use a switching regulator to implement quickly.
