It works!

Yes, yesterday’s Hello, World post counted as a post for the day, even if I didn’t even write anything.

I’ve been working on my Arduino interval timer project a lot. Got a bunch of parts and random electronics, including a FNIRSI Oscilloscope to help with testing. Finally got a breadboard. Got the cheap knockoff cable releases for the camera. They’re very good, by the way. Only $6 or so on eBay instead of $45ish from Canon (on Amazon.. MSRP $70! Sick.) It’s just a simple switch inside a simple plastic case… with a proprietary connector.

Anyway, I got the Arduino actually controlling the camera. All that’s really left now is to work on the software, and that’s coming along nicely. Initially, I just set it up to take as many pictures as the number I pressed on the keypad. There’s a video of that below:

Now, I can set up some variables in the software and get it to take pictures at interval, and set the exposures. The next step is to be able to set those variables from the device. This picture was a 500 second exposure, timed by the Arduino. While the shutter was open, the LCD display was counting down the time left. The lights were off in the room.
