Background: A few years back, I had low-frequency (125 Hz) RFID tags implanted in my hands. They sit between my thumb and forefinger in either hand, and I mostly use them to authenticate to my computers. I've had it in mind for some time, though, to integrate my RFID chips into my car as well. I'm starting this thread to track my new project - building an RFID Disabler for the starter motor. Hopefully there's be some interest and input as I go along! This project should be repeatable by anyone, and you can just use a regular RFID card or key tag instead of implanting one in your hands, haha.
Project goals: Require an RFID authentication from the driver before allowing the driver to start the engine.
Project status: Off The Ground! I just ordered the parts I'll need to prototype the circuit, and as soon as they come in I'll start the build. I put the parts-list below.
Parts
All in with shipping is about $150.
I'm going to implement the project in VHDL using an Altera FPGA because I had the prototyping board already. You could do this project using any Arduino as well, but I'll document the process in VHDL here.
ID-20 reader has a 200mm (7") read-range, and will be enclosed in an altoids mint tin. I hope to be able to read through the tin and interior trim - but can add an external antenna if needed later. The tin will be mounted under the trim below the dash on the driver's left hand side; the FPGA controller will go there too as long as there's room, otherwise I'll route that into the glove-box if needed. The system requires 5V DC power, so I bought a step-down converter that takes 6-36V in, and puts out a steady 5V 1amp supply.
The initial plan is to add this as a relay on the existing switch that the clutch triggers when depressed all the way. I believe there's a similar switch on the brake for DSG cars, but I'm not sure? I want to research that before I install into the vehicle to ensure anyone can do this project, not just manual owners.
The controller will support a "master tag" and some number more "driver tags". The master tag is needed to add/remove driver tags from the system. A valid driver tag will be required to start the car.
So that's my project outline - I hope you guys are interested . I'm going to reserve the first several replies for (1) hardware information, (2) programming / coding, and (3) install into the vehicle.
