Some fridges are always alarmed
Back to Bella Italia
A fridge that's alert for midnight snacks.
When you've popped in your fridge alarm, getting peckish in the middle of the night and forgetting to close the door - along with escalating electricity bills - will be a thing of the past. Italian inventor Flavio Dellepiane has designed a 3V battery-powered fridge alarm that beeps if you leave the door open for more than 20 seconds.

The Italian designers Flavio Dellepiane and Alberto Ricci Bitti, in particular, have submitted a number of excellent full projects.
The posts range from LEGO robots and fridge alarms to remote monitoring and plant watering systems. All involving Italian-originated submissions, check out:

Video: Booby trap trip wire alarm!
Kipkay is a Gadget Master of the first water. Check out his video on how to build your own (mechanical) movement detector.
The bill of materials will only cost a "couple of bucks", he says - fishing line, mouse trap, ring caps ("it's amazing how much of a bang these little guys put out"), tent pegs, nails, screws and rubber bands...
