Intervalometer

• Basically a device for manually taking X-second pictures consistently on a camera.
• Randy would like a way to connect one base unit to multiple cameras to take Gigapan resolution shots at the same exact time.
• Josh suggested using an optoisolator, which is a very good idea
• Based on 2 tutorials

here

• Uses tiny PIC and doesn't need external power. Uses a watchdog timer.
• However, doesn't have connections for additional cameras.
• “Listens” for button press on camera, WHICH IS SO SLICK, and has 2 diodes to allow voltage from either focus or shutter to power VDD, but not allow them to cross-talk.
• Adds 22uF capacitor for temporary power, but sometimes causes shutter to depress when pressing in initially

HDR Jack

• Another take, uses a button (doesn't listen), and doesn't really have a big capacitor?
• Input voltage goes to a pin (not VDD), which he says saves power
• Has HDR mode for taking different shutter exposure timings automagically.

Both use watchdog timers, and I'm thinking that's what I want to do too.
