A better picture is coming…<\/p><\/div>\n

My Computer Access Module was designed as a way for me to access my computer using the RFID chip implanted in my hand \ud83d\ude42<\/p>\n

It uses an Atmel 32U4 with Paul’s HalfKay bootloader to do keyboard emulation. When it detects the chip that I have in my hand (or any other programmed in 125KHz RFID tag), it types in a hardcoded password, just as a keyboard would. This allows a nicely customizable\u00a0entry system for a computer.<\/p>\n

It’s very basic and doesn’t have many frills. It was just a project that I threw together in a day or two because I wanted easier and secure access to my computer. The BOM ended up coming to around $50, most of this is the cost of the solid ID-20 RFID reader, and I am totally happy with that price. Definitely worth it for the nice RFID read distance. A few of these were manufactured to be distributed to my friends as well.<\/p>\n

Ensure that you select the proper “USB Type” in the Arduino menu when programming your board. It needs to be set as “Serial + Keyboard + Mouse + Joystick” if you want to use the serial debugging that is built into the program. Feel free to remove the Serial portion if you do not want the debugging (as in a final implementation).<\/p>\n","protected":false},"excerpt":{"rendered":"
