A few years ago, I wrote about how I had programmed a device to open my garage using radio frequency waves (RF) , similar to how regular garage door opener devices work.
This solution worked fine for test and demonstration purposes, but it was not very viable in the long run as I experienced on several occasions that [A] the signals not always got through and [B] the device occasionally became inoperable through the Linux kernel, forcing me to physically remove and re-insert the tranceiver in the computer to get it working again.
