Hello everyone,
My name is Tiago, and I'm excited to join the BadCaps community! I'm located Portugal, and I've been fascinated by electronics for as long as I can remember. While I've always tinkered a bit, my goal now is to really dive deep and learn how to diagnose and fix electronics properly.
I'm particularly drawn to the challenge of bringing "dead" devices back to life, understanding how they work at a component level, and troubleshooting complex issues.
I'm looking forward to contributing where I can, and eventually sharing my own repairs.
Cheers,
Tiago
