Recently, when sorting out computer data, I found a hardware dismantling DIY mechanical keyboard designed in 2012. The idea of current design can still be recalled. At that time, I was working in a well-known peripheral factory. Do ID design work. I met my friend who was running design outside at that time. The design of mechanical keyboard is needed to lift the big factory. At that time, e-commerce did not rise, and Internet cafes and channels were relatively popular. At that time, everyone used the keyboard or the three zones mainly, when playing games. The three-zone keyboard takes up too much space, so I wonder if I can divide the keyboard into a zone keyboard, a two-zone keyboard, and a separate number key zone. I designed this. and share it with everyone.
