I know absouletly nothing about designing circuits (I think that's

What kind of circuits?

>>59378240
Start with discrete mathematics, then go learn a hardware description language

Start with particle physics, then go learn a machine language.

>>59378374
Start with sucking my dick, then go die.

>>59378240
Start with a basic PCB design course on instructables or something.

Once you know that, you need to learn components and circuit design.

Once you know how to make components do what you want them to do, and you know how to make a board layout, you're golden.

Start by learning basic ohms law and simple resistor circuit.
Move onto transistor circuits, logic gates, etc.
Analog stuff if you feel it's necessary.

Start by learning to install Gentoo

For example, I built a PCB for one of my uni projects. The first thing I had to design was the battery protection circuit.
Because we used 3 cell lipos, the voltage couldn't drop below 3v per cell (just the way lipos are, can't be bothered explaining it). We used a voltage divider to only trigger a mosfet when the voltage was above 9v. When it fell below 9v, the mosfet would 'turn off' the circuit.

i remember seeing some circuit game-like websites posted here. Basically challenges to do something by dragging and dropping components, connecting with silicon and metal. Don't have a link tho.

I got learning back in the day with a series of Radio Shack books and a few other including the ARRL handbook (big annual ham radio) which has a huge section on circuit and antenna design right form basic on up.
Anything that starts from the basics and covers the main circuit types that make up almost everything is good.

The most important things you can buy are some breadboards, and jumper wires to use with the breadboard.
My best friend was my de-soldering iron though, I would spend hours de-soldering shit from old electronics and anything I could find to build up a large inventory of components without having to buy everything.
Usually I would by packs of resistors though because their leads are usually cut too short on circuit boards to reuse.
A nice first project is to build a power supply for your breadboard.

This is what you wind up doing with the breadboard.

Learn Eagle, or maybe Kicad.
Learn basic circuit theory.

Enjoy.

Kicad, eagle requires an account and to always be online now.

>>59380479
Honestly that's why I suggested Kicad too.
The interactive router in Kicad is something else though, like holy shit.
