Design your own amplifier did you? Or just slavishly copy the layout in the magazines.
Mashing up other people's work to create something different, and possibly better, is what we call progress.
The nice thing about this otherwise fairly useless gadget is that you DO write a program from scratch. Yes you drag and drop rather than typing linker commands in the console but you understand algorithms, functions, things happening as a response to other things. Much better than being sat down in front of an IDE and told to copy 100 lines of initialization boiler plate without understanding it, and without getting a single character wrong, just so you can get a blank window to appear.
