Your own easy to build high performance logic analyzer for less than 10$.
Scanalogic is a simple, yet effective logic analyzer specially designed to be easily built by beginners, so that it can be used for debugging and analyzing their projects. It can be used at sampling rates as high as 4 Million Samples per second. It has only 4 channels, but that is more than enough for most hobby projects, further more, most communication buses nowadays have very few transmission lines, ranging from 2 to 4, so decided 4 was more than enough.
Scanalogic is a combination of a hardware and software application. The hardware is as simple as it can get: An ATMEGA16 micro controller and a NAND gate!
