Hello all! If you're reading this thread then thank you for taking the time to read and/or reply! I appreciate it! Onto the guts of the thread. Here I will list what I am trying to do, the associated questions that I have found reasonable to ask, and then any additional details I will note below. My goal is to make a power supply for my small electronics projects which are mainly for experimentation (e.g. circuit testing/analysis, small LED emitter/receiver circuits, etc.). Almost 95% of the time I am using Lantern Batteries (6V) or a 9V battery to power my breadboard for my small circuits. My next go is using my new oscilloscope (being shipped currently) and also my new LC meter to test some inductor/capacitor circuits and testing other wave forms. Obviously you can't have induction if you don't have AC supplying the juice to the coils. I also do a lot of experiments/projects for my family using electromagnets, which if were supplied with AC would eliminate the need for enameled copper wire eXacto knife scrapping. Some questions that I have wanted to ask and get answered since taking up this idea, is what is a relatable voltage in AC for what I am using currently (my DC batteries)? I would like to know because I am often touching my components and replacing parts, and I will always use a voltage appropriate for my environment, which is my wife & children. So with safety in mind I never use anything that will cause harm if one was to come into contact with the circuitry. I also power things that require very little amperage, such as LEDs, microcontrollers, DC motors etc. Basically what I want to know is what do I have to step down mains power (110VAC @ 60Hz) from my wall to a lower VAC, so that it is comparable to my 6VDC 20mA - 70mA draw? My circuit so far is rather simple, use a power cord to connect to my power outlet, which will be supplying a step-down transformer, which I will then have powering my breadboard at some reasonable voltage. I would like to integrate a fuse perhaps for safety, and I would like to keep the voltage stable and constant, so surgers don't kill my circuits. Any and ALL feedback is appreciated & welcomed. Thank you again for taking your time to read this thread!
