    Do you know where I can get a good power supply and oscilloscope? I've tried EBay, amazon and a few electronics distributors but I run into either the "too expensive" problem, or the "I think they are tryin to sell me a painted cardboard box" situation. Any help? I would almost be willing to build my own from scratch, but there is no "for dummies" books out there, on that topic -_-

    Building a power supply is fairly easy but the scope is another story. Depending on what you need you may be able to use a computer's audio input as a cheap & dirty scope. There are kits out there & at least 1 Instructable on here about building one. https://www.instructables.com/id/PC-SOUND-CARD-SCOPE-INTERFACE-FACILITATES-DC-RESTO/.

    If you don't need a variable power supply you could use a modified PC power supply. There are any number of Instructables on this. Gives you +-12,+5 & +3.3v ,good for most anything you want to do.

    Ah! I will look into those! Thank you!
