Getting up to speed

Doppleganger
Doppleganger over 2 years ago

Morning

Temporarily retired Canadian here. Ive been trying to teach myself some basic electronics, mostly for a hobby but if i feel confident ill go back to the local college in the fall. Unfortunately ive been getting jammed up on the math. Numbers weren't a huge priority when i was a kid, so sadly im really far behind. Does anyone know of a reliable site to learn electronics specific math, and schematics while im at it, should probably get better at that too before i start melting too many things.

    You can visit khan academy. Personally, I was benefited by their math videos when I needed to brush up some math for my projects.

    If you dig, you might be able to find the old SAMS electronics classes.

    We used them when I went to tech school half a century ago, but they were simple, easy to understand and helped you learn the math along the way.

    If you're learning and want to experiment, then these three kits of components are very good (saves a lot compared to buying the parts individually):

    Resistor kit

    Ceramic capacitor kit

    Electrolytic capacitor kit

    They are parts kits available from Newark, prepared by Velleman, they are of decent quality, and low-cost. I've purchased these kits at least a couple of times in the past and still use them, they are perfect for beginners and for prototyping stuff up on a breadboard quickly. I can't buy these parts cheaper individually, and they will all mostly get used, so there's no waste.

    Those generic parts are cheaper individually in same quantity. About 1/3 the price for same quality.

    I've not seen them cheaper at Farnell (unless it's per-part but purchased in much larger quantities), especially the wire-ended ceramic capacitors, which are quite expensive now. Maybe it's cheaper at Newark, or other suppliers? I've seen lots of packs of generic resistors/capacitors etc on Amazon/eBay, but I don't know what I'm getting if I buy that. The Velleman parts kits have been the same for at least a decade.

    Doppleganger I'm going to recommend a new discovery to me - the Analog Devices Engineering University Program.  When you get into the individual labs, there is the math that is specific to that circuit and that's it.  The schematics - and wiring diagrams - are very straight forward due to their specific scope.  It might be worth a look.

    Yes, I'm talking 500 same value. I'm certain hobbyists only use a few values out of those kits.

    Most manufacturers have similar programs and online circuit design help or simulations.
