Generic Code-Seeking Diassembler with Fuzzy-Function Analyzer
...The original purpose of the Fuzzy Function Analyzer was to assist in code recovery where the source code for the current binaries got lost, yet the source code for an old binary was retained. The Fuzzy Function Analyzer allows you to match up known functions between the two binaries so you can concentrate on disassembling and reverse engineering the parts that are different and recover the code for the current binary that got lost.
SoundStepper is a "100% software" telescope controller, for Windows, using audio hardware to control step motors at real time. All it requires to operate are external step motor drives, which can be a commercial "pulse/direction" drive or analog current amplifiers.
