DSLogic is an interesting open source 200MHz logic analyzer project on Kickstarter.
Most of electronic instruments are designed in professional fashion. They are dedicated, traditional, well functioned, and most importantly, expensive. They are usually only available and affordable to academic and industry. Individuals, however, are not lucky enough to get the best electronic instruments as they want. This is how we are inspired to make DSLogic. [...]
DSLogic consists of DSLogic-Core and extension modules. DSLogic-Core is a re-configurable circuit board based on FPGA technology with maximum 200MHz sampling rate and 64Mbit on-board memory. DSLogic-Core can work alone as a fully functional logic analyzer, along with various extension modules. DSLogic can also work as oscilloscope, data acquisition system, protocol analyzer and even RF analyzer.
