Need to Make DC supply & Function Generator

  1. I wanted advice I saw that DC supply, function generators, and Digital Oscilloscopes were really expensive and I wanted to know is there some way you can use software to turn your PC into a variable DC supply and/or a Function Generator thanks

    You can also build an oscope for not a whole lot of money, but this can be a very involved process.

    Here's a helpful link for doing it pc style:
