ATtiny85 and USB Business Card

Atmel ATtiny85 microcontroller with USB Business Card project is quite interesting, with very few elements ATtiny85 established internal RC oscillator circuit frequency 16.5 MHz is used. pcb usb connector on the USB socket designed for the 1.6 mm thick PCB does not stop on the loose plaque on the printed circuit previously shared ATtiny85 USB Password Generator software as well as the USB interface made ​​with the V-USB driver. Circuit connected to the computer USB Business Card Notepad program opens the keyboard "Caps" key 2 times the pressure information contained in the microcontroller automatically written to the notepad window ..

also has 452 lines of source code written in the C source of the project, hex, and other source code, there are eagle files ..
