A Clever DIY Alarm For your Camera Bag

If you ever took a camera bag to a restaurant, coffee shop or anywhere that makes you put it on the floor, you know that can be really be a peace killer. And you are constantly worried that someone might snatch it.

You try placing the bag under the seat / have one of the straps loop around the chair legs and put it in your lap. Not really convenient.

Youtue user Kipkay came up with a clever $2.5 hack that may not protect your bag, but will definitely let you know if someone is trying to pick it up.

The system is based on a $2 impact alarm (the kind that alerts on broken windows) with an added $0.5 tilt switch. Once the device is turned on any tilt, such as a bag grab, will trigger the alarm. (As with everything, there are commercial options for this, but they are not nearly as cool)

Now here is the clever part (back in my programming days we used to call those “features”). The alarm has not off switch. Once it goes on it can only be turned off by drowning it, smashing it or…applying a magnet to the tilt switch, which is not that trivial if you just picked up this bag and started running. Where would you even get a magnet.
