Drive an RC car with HackRF

See this presentation for more details.

How to use it

You will need:

• A HackRF
• A cheap remote control toy car. I used a "coke can mini rc car" my friend ordered from China, but apparently many toys use the same protocol.

Install the pre-requisites (tested on Ubuntu 15.04):

apt-get install libhackrf-dev
sudo cpanm PDL SDR::Radio::HackRF Valence

Figure out the car's operating frequency with a frequency counter, GNU Radio, GQRX, whatever, then run the script:

$ perl bin/rccar-drive 35_470_000

Use the arrow keys to drive your car around. Have fun!
