As I was writing up the user guide to the Triggertrap V1, I was googling around to find out what kind of sensors you could conceivably connect to the Aux port of the device. I came across a sensor I didn't even realise existed: An Alcohol Gas Sensor.

Brilliant. Spectacularly brilliant. Why? Because it gave me an idea for a completely novel way to use the Triggertrap that I hadn't thought up quite yet. You probably see where this is going already, because once you know that such a thing as an Alcohol Gas Sensor exists, the idea writes itself:

The Wobbly Photo Booth.

For parties, rig up a 'photo booth', connected to the Triggertrap V1, that measures the alcohol content of your breath. If you're sloshed enough, it'll take a photo of you!

To create something this awesome, all you need is a $4.95 Alcohol Gas Sensor wired to your Triggertrap. Now, you need to calibrate the device. You can either use mathematics, or you use a reference: Pick someone who seems quite inebriated, and get them to blow on the alcohol sensor. Set the Threshold on the Triggertrap's Aux sensor to the value they just blew, and get everybody to try.

Get ready to Facebook a gallery only of the most sloshed people at your party! Fabulous.

Of course, the Wobbly Photo Booth is simply one of many, many other sensors you could use to trigger your cameras.

This little project illustrates why I'm so excited that we included an Aux port on the Triggertrap - it opens up for all sorts of crazy and creative uses of the device, letting trigger the camera using literally anything you can think of.
