>RULES
0. Electrics ≠ electronics. Mains wiring goes to /qtddtot/ or /sqt/. PC assembly to >>>/g/.
1. Do your own homework. Re-read all documentation/datasheets related to your components/circuits, and do an honest web search, before asking.
2. Pics > 1000 words. Post relevant schematic/picture/sketch/9001.5 hours in MS Paint with all part numbers/values/etc. when asking for help. Focus/lighting counts.
3. Read posts fully. Solve more problems than you create.
4. /ohm/ is an anonymous, non-smoking general.

>I'm new to electronics, where to get started?
It is an art/science of applying principles to requirements. Find problem, learn principles, design and verify solution, build, test, post results, repeat.

>I'm new to electronics, where to get started?
There are several good books and YouTube channels that are commonly recommended for beginners and those wanting to learn more, many with advanced techniques. The best way to get involved in electronics is just to make stuff. Don't be afraid to get your hands dirty.

KiCAD (recommended)
CircuitMaker
Circuit Wizard
Various high-end commercial offerings (Altium, etc)

>My circuit doesn't work. Halp?
Check wiring, soldering, part pinouts, and board artwork if applicable, then post schematic. Supply ALL relevant info and component values when asking a question.

Gonna follow this thread Chrismas is coming for gf too ;D

So, do you have any mechanical/electrical schematics to show us?

So I'm building a circuit that will control the headlights on a car. A car usually runs around 10-14VDC and the lights draw about 70W of power. Thing is that I want to measure current using a shunt resistor before the headlight, the resistor has to be about 0.01ohm or something around that. How do I choose a resistor that cant take the current from the headlight passing through`?
