For whatever reason, periodically I find myself wanting an electronic stopwatch. No fancy features, just a start button and elapsed time. Several months ago I found one, but I lost it and it didn’t do what I wanted anyway.
Fortunately, I have mad C# skills, so I pounded one out a few months ago.
Requires: .NET 2.0 (it should work on Mono).
Visual Studio 2005 sources included.
