My girlfriends car, along with another one in the same parking lot were broken into last night. They took her radio surprisingly without damaging the dash. From the neighbor's car they stole ID's and gift cards.
It's has my blood boiling and I know most thieves can disarm modern alarm systems these days. I was thinking of making something that would cause panic and make them bail before being able to steal anything.
One of my ideas is installing a set of super bright lights tucked behind the top part of the backseat where it meets the back window panel. Rig it to the some light switch that activates when the door is open and have the lights strobe incredibly fast and bright. Maybe even activate an annoying sounding horn. It could be turned on and off in the trunk and easily switched on when need be.
Any ideas on circuits and such to accomplish this? Thinking of using a separate power source as well.
