Snapping pics at the right moment with a pressure plate

[BiOzZ] built a pressure sensitive camera accessory to snap pictures at just the right moment. Before turning out all the lights the camera is set up with a twenty-second timer and a three-second exposure. The pressure plate doesn’t take the photo, but fires the flash to catch an image in the middle of the action.

The hack uses a piece of acrylic as the base of the pressure plate. A switch is constructed by placing aluminum tape on the base, and attaching a thin metal strip that is bent to add just a bit of spring. When an object is place on the plate the thin metal contacts the aluminum tape completing the circuit, a change in the weight breaks it. A simple circuit connects to this, using a relay to actuate the flash from a disposable camera. This is perfect for documenting the moment when you exercise that fruit-induced rage that has been consuming you lately.

Laser etching fruit

Ever annoyed by those pesky stickers on your fruit?  They never seem to pull off in one piece and they always leave a little glue behind. Well, the industry might be moving away from them in favor of laser etching each piece of fruit. They are using a low energy carbon dioxide laser to etch the skin. The FDA is in the final stages of approval for using this in the states. It is already in use in New Zealand. We might find this a bit weird, but we’ve seen weirder.
