Very cool. Years ago, I picked up a D-Link DSB-R100
– a USB-powered radio that’s an antenna and FM tuner with an audio jack
for output. Sadly, it doesn’t look like D-Link is selling them any
more, but they only cost $29 originally, so you might be able to pick
one up cheap second-hand (there’s one on eBay today). Originally, the
software it came with only ran on Windows 98, although D-Link is
offering drivers for other Windows versions now. However, Open Source
advocates got their hands on it, and provided software for Linux and for Mac OS X. Now, I can write a simple script to capture my favorite shows and listen to them at my leisure.
