Antitheft Suitcase using Motorola E-Field Sensor

at 5:18 am. Filed under Complex Hacks, DIY Hacks, Electronic Hacks


Having something stolen is one of the worst feelings, this Antitheft Suitcase design uses Motorola E-Field Sensor to combat theft by allowing you to enter in a code to disarm your bag.

"Loss or theft of suitcase during travel is a common occurance. It has recently happened to my dad also. This got me thinking. Also I have heard of jeweller suitcases that have alarms and also shocks a potential thief. A similar device can be implemented using an e-field sensor. This is much simpler than wiring the suitcase in any other way. There are 4 metal foil tabs, 2 on the left and 2 on the right. These are used as key pads to enter the arm/disarm codes. They are also wired to three e-field electrodes which is used instead of mechanical keys."
