This.
I went the buzz cut route and I get laid just as much as before (never).

>RULES
0. Electrics ≠ electronics. Appliances/mains stuff to /qtddtot/ or /sqt/. PC assembly to >>>/g/.
1. Do your own homework. Search web first. Re-read all documentation/datasheets related to your components/circuits. THEN ask.
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

> tried scraping the carbon off and soldering directly to the board before

old keyboards, some of them at least, used copper pads instead of carbon.

if you cant find one of those, scrape off the green stuff (solder resist) from the traces and solder 30-AWG wire wrap wire to it.
