Reapberry Pi is getting famous during past six months. It is a tiny computer. As small as a credit card. Maybe smaller than credit card. The price of the latest Raspberry Pi Model B rev2 is $35.00. To use the Raspberry, the following items are required: USB keyboard and mouse.
Got a new toy, USB TV tuner, from NCIX.com. Hauppauge WINTV-USB2-FM Analog TV Stick. I plugged it into one USB port. Installed the software from the CD. And connect the TV cable with the usb stick. Run the program to scan the channels. I got 50+ with shaw cable.
