I know next to nothing about electronics which is kind of embarrassing since my dad was an electrical engineer. He designed missile guidance systems, and I can barely operate a flashlight. I must have missed out on that gene. Anyway, if I’m doing any kind of project that involves electronics I have to have the real dummy’s version of how to do it. There are some things that I would like to do or know how to do to help with my survival preparations that involve electronics. I haven’t done any of these projects yet, but I have searched the web and bookmarked several sites that have instructions that I feel like I could follow. And if I can follow them that means that pretty much anybody can follow them. Besides simple and clear instructions, my other criteria for choosing these sites is lots of pictures to illustrate the process, and few or no exotic parts required. I can’t vouch for the info on these sites, and I don’t know how long they will be active, but you might want to take a look at them if you are interested in building any of this stuff.
