 Hi! I'm a "self made" hobbyist man with passion for electronics and software development! 
 This is the best forum for grown my knowledge, sometime I try to fix my friends electronics devices like laptop, desktop and some phones.
 My real job is software development but I'm study by myself electronics (mainly from forums and youtube video..) and try to fix things 
 I'm also really "Retro" enthusiast and I've a pretty collection of old devices, from commodore, Amstrad, Spectrum etc.
