Itty Bitty Radio Telescope
Date: Sat, November 10, 2007
When I was in college, I wanted to build a radio telescope but couldn't get the funding to do so. But I found this site that shows a VERY easy way to get into radio astronomy.
Old Dish Network and DirecTV antennas are cropping up for a couple of bucks each at thrift stores so you could get into this for very little money.
