Hey /diy/,

I was curious. What is the best way to teach yourself electronics?

I was never the best at math but would love to learn about how electronic devices work and eventually a bit of programming.

Are there kits/books you could recommend to help me brush up on my math and learn electronics/circuitry at the same time?

Building a 555 circuit is a good beginner project. Start by flashing an LED and teach yourself the basics of current/voltage to calculate the right resistor. What's great is once you have this done you can have fun expanding it, like using the pulses to drive a binary counter, using potentiometers for variable frequency, or connect it to a big transistor to drive a motor or bulb.

What are the prerequisites to learning electronics?

>> No.338234

>>338185

there's three parts, really, to learning electroncis. all related.

one, a tiny bit of theory on what various components do. at least the rudiments of what current and voltage and resistance are. dont freak out here, jump ahead and go for making shit, but real soon now you'll need to know that shit. ohms law is generally the most complex "math" you'll need -- it's a simple proportion, so a division is generally the most complex

the manual techniques of parts, wire, components, perf boards, breadboards, etc. soldering, practical assembly of tiny parts whose function you cannot see! this simply requires SHUT UP AND DO IT. not that amenable to reading and thinking.

last, but not least! schematics and wiring diagrams. DIFFERENT THINGS! schematics are 'this is what i mean' (idealized) and wiring diags are 'this is how it is assembled' (which color wire).

schematics are like sheet music, only much easier. for super-simply circuits like OPs pic schematic can actually look like 'wiring diagram' (whic pic is sorta like) but with any complexity,t hey dont stay that simple.

last thing is, fucking persist at it. its a skill, and takes time to learn. there's a cerebral knowlesge part, and a physical skills part. physical skills are often lumped in with shovelling shit and digging ditches but that's fucked up. physical skills are what separates fuckwit office-cubicle-fillers from real engineers and experimenters.

Wikipedia is a great place to start. You don't need to understand quantum mechanics for basic shit, the Bohr model of the atom is fine. Look up metallic bonds for why electricity flows. Ohms law, ac vs dc voltages and how they behave in different components. If you are interested in ac circuits look up reactance. If you are interested in wireless shit look up electromagnetic radiation. Once you start reading an article you should find plenty of links to other related pages. Just read.

meh. too old-world, and waaaay too expensive. that's a 1960's approach.

others will disagree, but a modern take is something like this. $100, only because you seem willing to spend that. you can pick smaller kits or parts fo ra particular project:

https://www.sparkfun.com/products/11227

if you have any particular things you think you care more about (music/sound, computer stuff, robotics, vehicles, etc) then look fo rthings pertaining to that.

you can go theory/research first, or hands-on first, depending on how you work (i'm th elatter).

as soon as i post this anons will say "hurrdurr $30 arduino waste make yr own" ignore them. armchair oversimplification (actually making things complicated). yoru first time through make your life easy you'll have more fun learn more.

>> No.338328

these kind of kits are fine for somebody who just wants to create interesting devices but they dont teach theoretical aspects, such as how a transistor turns on or off.
I've seen the manual for this particular kit, and there are many cool projects in it.

>> No.338331

Fucking assholes think you need to learn advanced electronics theory to make a led blink. Total bullshit and five years later you will still not have started anything. Just buy some radioshack books and kits. You should be able to get going with all the gear you need for under $200 as a beginner. If you want to do anything over 9v power consumption, then take the time to study

>> No.338338

Sure you don't need to learn theory to make an LED blink, but you need to know why the LED blinks. That's how you get past the arduino stage, and go on to bigger and better things.

Heh, yeah, I started out by jumping into an old TV and making a small Tesla coil. I didn't know anything beyond simple house wiring before that and 0 theory, but I still made the coil and it worked for a time.

Honestly just go to some thrift stores. The best electronics book I have was $1.79 from a St Vincent de Pauls, you'll find old books but most of this shit doesn't change.

The other thing I used to do was I'd buy cheap sound-making toys and try circuit bending them,I'd find the resistor that controlled pitch and I'd try different values in there and I'd short circuit different connections. I broke more than my fair share of toys but I paid so little for them it didn't matter.

There isn't anything inherently wrong with the Arduino platform. It's the package/cut and paste concept that irritates me.

It's nothing more than a nice hardware platform for the mega series microcontrollers. You can always program it in the mega AVR code...

>Is it really okay to just buy an ardunio kit and jump in with no prior knowledge of how electricity or circuitry works?

Sure why not? An ardunio kit isn't really going to teach you much more than microcontroller programming, which is fine. You'll need other resources to learn how to build the circuits that feed into the Arduino (unless you just want to blink of LEDs or something really simple).

Learning EE/electronics/circuits really depends on what you want to do/learn. Programming stuff, any microcontroller is a good start (ardunio, basic stamp, ect..) A lot of digital stuff is fairly straightforward once you build a good understanding of how it works. (Just a lot of reading and research.) Things like analog discrete (like an audio power amp) require a good deal of specific understanding about the basics. That type of stuff gets down to basics, and at that point you'd be looking at electrical engineering books.

I'd see if any community colleges in your area offer courses on electronics. I'm almost finished with my first class (Digital) and am taking DC next semester. Not only do you meet people who are noobs like you, but you also learn quicker when you have tests coming up.

I seriously reccomend it, these books help, but having a classroom with other students learning the same thing is the best way to go about it.

You could do an online course. MIT 6.002x is excellent in my opinion.
You will be forced to learn (or relearn) algebra, calculus and complex numbers to finish the course. I used wxmaxima (free symbolic math software) and LTSPICE (free circuit simulation software) to complete and check most of my work.
It took a bit of effort but was well worth it to me. Knowing the fundamentals makes advanced stuff approachable instead of overwhelming.
