| 1 | This is a project I made because I wanted to use an old Dell full-sized keyboard on my laptop. The key feel of this keyboard is very good and I type a lot, you know. |

| 3 | The hardware is identical to [wiki:ak2usb]. Only the firmware is different. As both devices use an usb bootloader, it is easy to switch from one to the other as needed. |

| 5 | == Hardware == |
| 6 | Very simple hardware : |
| 7 | * usb port done using v-usb and using their reference schematics |
| 8 | * PS/2 port done using my own library, bit-banging |
| 9 | * A jumper for firmware upgrade |

| 11 | Single side PCB with some SMD parts to make it smaller |

| 13 | == Bootloader == |
| 14 | I used the USBaspLoader, which takes some space (1024 bytes) on the device but is easy to work with and appropriate for this kind of devices. There is a jumper on the board you have to fit to enable upgrade mode. Else it will start in regular mode and act as a keyboard. |
