G'day !! I am here due to being on the receiving end of a 0day APT hack which has in turn bricked all 6-8 laptops, servers, TV and everything else but the toaster.. and this requires re-flashing with a hardware programmer :P

Hi guys! I'm currently planning to study electronics engineering in university. In the meantime, I'm just tinkering with some old broken electronics, and thought of looking here for the schematics to them.
Wow, it's pretty interesting, looking through all the old posts in this thread. Don't even think anyone will read this oneComment

Hey everyone!
I'm a 26-year-old field engineer from Italy. I work for a big broadcasting company in the telecommunications industry. My job is to manage LAN networks, radio links, transmitters, electrical systems, uninterruptible power supplies, and generators. I've always loved electronics, and lately, I've been trying to learn how to repair things at the component level. It's a lot to learn, but I'm having fun!
One thing about me is that I'm colorblind. So, sometimes it's hard for me to tell the difference between green and yellow LEDs. (It makes things interesting!) Also, I have to admit that the image CAPTCHA had me stumped. I had to try four times before I got it right!
I'm looking forward to joining the discussions here and learning from all of you!
