Hello, Im looking for an "easy" but cool electrical engineering project. Ive tried to make a mini tesla coil, but I keep messing up the coil part itself, so im taking a step back from it for a while. Are there any relatively easy (I am beginning) electrical projects that you have heard of, seen, or done yourself? I would like to learn something from the project so I can apply that concept to future projects and help me understand the properties of electricity better. I also have an interest in magnetism, so a project that has to deal with electromagnetism would be cool too! Also, Id rather not spend too much money. My limit would probably be around $20. Thanks alot!
