See this presentation for more details.
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!
