| Roughly in order Beginner * Get a Miniware TS101 USB C soldering iron, some solder, solder wick, flux * Get a mediocre multimeter * Do a little soldering assembly kit to learn how to solder, there are some good NASA manuals and videos to learn techniques and you won't need to do as good a job as they do * Learn how to identify and replace broken capacitors * Learn how to replace power and USB connectors * ^ (a huge proportion of things that are fixable at all are going to be those two) Intermediate * Learn about static (ESD) safety, get the equipment and supplies to prevent frying things yourself * Get an arduino or other low cost prototyping board and learn to program it and do little projects * Find some broken consumer electronics with guides on https://www.ifixit.com/Guide and try to fix them, these things are often less about "electronics" and more about glue * Read the parts of Zen and the Art of Motorcycle Maintenance about maintaining and fixing things * Read https://www.eevblog.com and watch https://www.youtube.com/eevblog for information and inspiration Advanced * Get an oscilloscope and bench power supply, learn how to probe and analyze signals on boards * Figure out yourself what next steps to pursue, you should be able to at this point, or at least to ask more specific questions |
