If you are learning electronics or thinking of it as a future hobby, here are some fun projects to begin with. They: will be extremely useful (particularly in emergencies),will not waste your time or money andare quite easy to make. Just one of these projects uses AC (alternating current). The rest work on DC (direct current) and are safe for kids (if you think soldering is safe). These projects are good for the environment too, as they reuse electronic parts that would have been discarded. If you are a prepper or survivalist, then you will be happy that all the projects will run off-the-grid, as they can consume renewable energy. For the tinkerer, there are projects that add MORE POWER than what the manufacturer had designed for. For the parent of lazy children, there are annoying alarms that can wake up the dead. Everything is explained in plain English. Simple and straight-forward. No exotic projects or obscure concepts.
