Meu nome é Tyler, sou um orgulhoso pai de duas meninas. No início dos meus 20 anos. Tenho minha certificação automotiva. Tenho trabalhado em computadores fazendo instalações básicas de sistema operacional, substituições de PSU, mods de gabinete, atualização de CPU e RAM... compilações completas... etc. Mas eu realmente não fiz nada em um nível competente fora das portas de carregamento em laptops.Inscrevi-me porque encontrei este site enquanto fazia uma busca louca para consertar um LCD e fiquei muito impressionado com a riqueza de conhecimento aqui. Certamente usarei este site e escolherei os cérebros de pessoas mais inteligentes. haha Obrigado pela leitura e tenha um ótimo dia.Comment

Hi,
I am a learning Electronics enthusiast, who has caught the Electronics bug.
I am registered disabled with limited mobility, so can do certain things. I have found that Electronics allows me to take my mind away from the daily pain and discomfort.
Anyway, from me and from the good words of Porky Pig... 🐷 Th-Th-The-The-Th-Th-Th-Tha- That's All folks!!!Comment
