Open Chargeport
What is it?
As the name suggests, it's a transmitter that will open the charge port of a Model S.
Last week I received my EU spec model S, and charged a few times with the cable Tesla supplies with the car.
The button to open the Charge port door, really is a nice feature.
As there is no such thing on a standard Type 2 charge cable, i now have to open the car door, touch the battery icon, and select open charge port. Not very convenient.
Therefore i wanted to make my own transmitter that opens the chargeport, and that can be fitted into a standard Type2 plug.
Credits to Banahogg who documented his attempts to analyze the RF data here
which helped me finish this project in a few days.
The components needed:
I used a 433 Mhz module connected to a PIC microcontroller. (US model S, might require a 315Mhz module)
Only a few other components are required.
1x PIC12F1822 microcontroller
1x TX-SAW MID/3V
1x Lithium cell, 3V
2x 100nf capacitor
1x 10uf capacitor
1x pushbutton
Feel free to build your own Open Chargeport, or improve it. PIC sourcecode can be downloaded from Github:

The chip inside the Model S charge plug is a Si4010, i have made a version for this chip as well, will upload it to Github soon.
