Hi, I'm new here and I saw your car was stolen. I'm feeling very sorry for you mate!:cry
But I may have a solution for you to prevent this from happening again.:fy1 Hope you can read English because my Dutch sucks!
I am an electronics design engineer and I designed a "startonderbreker" a while ago. It's pretty simple for a novice electronics geek to solder it together on a piece of perf board and the materials won't have to cost more than €10-20.
It works great!! Several times in the past they tried to rip my car, but never succeeded because it's not a standard system. It's nearly impossible to figure out when you don't know what's been done.
Here's the design schematic:
In practise it works as follows:
You turn the ignition key to make contact, then you need to operate the switch which will connect any bypassed connections between the engine and control unit. The engine starts.... Then I have incorporated a time delay which will keep the connections in tact for a few minutes so if you want to make a short quick stop (to adjust your GPS or whatever, write an SMS..) you don't need to re-activate it, engine still starts.
If you are going to leave the car for longer anyway and want to activate the safety stop right away then press the same button with the ignition key off and the system will activate right away, without delay.
I have included an LED which will be lit for as long as the delay is activated, it will only be lit when the ignition key is off. After the delay time when the light is out the car won't start until the button is pressed.
The circuit draws no power when the car is parked and the delay time is passed, when the button is pressed it'll draw just 160mA!!:vertag
Car thieves, eat that!!!:fy1
