A gamer’s motion, a programmer’s voice, a DJ’s instrument and a designer’s brush; a single keyboard plays multiple roles in a computer. Similar is the case of a computer mouse that can make clicks to move a card in solitaire or open a web browser. For a computer buff of the current times, imagining a computer without these input accessories is impossible. Hence, it is utterly needed for these gadgets to tightly connect to the computer 24 x 7. Enabling a good connection are the PS2 connectors that have been in trend since a long time. Invented by IBM PCs, PS2 or personal station 2 connectors have reigned as sole connectors for keyboards and mouse for a long time. Easy manufacturing, ability to link tightly and fewer chances for connection error make it interesting to explore the insides of these connectors.
Just as a PC software, that are being used in PCs to increase the typing skill and speed in a computer keyboard, this device has been developed to do the same job but without any PC. The device has a PS/2 keyboard port to connect a computer PS/2 keyboard (not an USB keyboard) and a LCD screen to display. When the circuit is assembled and programmed, a PS/2 keyboard has to be connected at the PS/2 socket provided in the device and it then serves as a portable TYPING ENHANCER. It needs only a 5V power supply and nothing else. It has no connection with PC.
