i fixed a lamp the other day!
cheap LED lamp i was using for light at my "messy" desk, started flickering real bad. somehow i have acquired enough intuition to immediately think bad capacitor? and incredibly, i was right! bad capacitor right before the transformer in the power brick. found it because i figured that's where a cap would go bad, and tested it first. then tested a bunch of other caps both on that board and just in my parts organizers to make sure i was testing it right. then i happened to have a capacitor that matched it that i had harvested from something else, and i swapped it in! and it fucking worked!!!!
fixing stuff is genuinely one of the most rewarding things i do. on top of the pretty widely understood rewarding feeling of developing a skill and solving problems, it's nice to be able to fight consumerism, even in a very small way.
