Mad Photo Booth

Just to let you know this post is pretty darn geeky.  Most of you will just look at the pictures, which is just fine with me :-)

I've been playing with Arduino, an inexpensive, easy to program microcontroller.  I started with an experimenters kit from here, and burned through all of the practice circuits in two days.  Rubin gave me an infrared LED, and I started to wonder if I could use the Arduino to control a camera.  After quite a bit of experimenting, I had a working prototype together with the following breadboard layout:


When you push the button the red LED flashes for a period of time (7.5s) and then the IR LED is used to trigger the camera five times with one second between (all times configurable in the script).  We rented a backdrop from the local camera store for less than $50 and Lisa found all kinds of great props on Etsy.

Knowing that there wasn't any way a breadboard with a tiny push button switch would have any kind of WAF (wife acceptance factor), I got on ebay and ordered some big red buttons, and crafted a button with a status light from a radio shack project box and some cute 4 connector intercom wire.

After seeing the whole setup, Lisa remarked: "I didn't know you could make something so professional", which was a proud moment for me. 

The photo booth ended up being the hit of the party. Usually you have about 3 photos from a party and this time we ended up with hundreds.  Many of which are so fantastic they aren't fit for the blog.

The best thing about Arduino is the super-helpful community.  Nearly everything that I used for this project was cobbled together from friends.  In that same spirit, here's all the necessary Arduino code bits:

Thanks for sharing this! I was wondering if you could also share the components you needed for the wiring and what camera you've used?

I used a Nikon D7000. There are IR codes for canon cameras too. For the wiring I just used radio shack "intercom wire" It was lady approved with 4 connectors in green, red, black and white. Let me know if you have more questions!
