Hi,
My son is doing a grade 8 science project.
My son wants to create an invention that allows it to "beep" at him when he leaves the house. He can then go over and press a button and a message will remind him of something. Since other family members leave the house, he doesn't want this device to go off - except when it is him.
He is looking for a "chip", "sensor", something that he can put into his knapsack so that it will trigger when he leaves the house (only him and not the rest of the family). This is very similar to big security systems at stores and libraries (where it tries to beep at you when you leave with an item). We have not been able to find something for home use.
He wants to add an LCD clock & tape recorder to this device.
Are there kits out there? I've gone to the various electronic stores in my area and no one has been able to help. I've also gone to a spy security store and they don't have anything . Am I looking in the wrong direction?
Any help would be appreciated. Thanks...
