AVR with PS/2 Keyboard and HPDL-2416 Display

I hooked an old PS/2 keyboard and a vintage HPDL-2416 alphanumeric LED display up an ATmega168. You can type messages in with the keyboard and scroll them across the display. Messages can also be saved to EEPROM and retrieved after the power has been turned off.

The HPDL-2416 is an incredibly easy-to-use part; 4-character display, built-in memory, refresh circuitry, and ASCII decoder. Plus it just looks freaking awesome. Eventually I hope to get some more LED displays and make an AVR-based terminal. (probably with a serial, USB, or Ethernet link!)

Can you share this project? I have one HPDL 2416 and i like to do this schematic!

very cool, love the display.... only nixie tubes would be more exotic? : )

holly shit, i wish i could make something so cool

[fireraisr]

awesome

wow, really nice project. i myself tried to read out a PS/2 mouse with an AVR but stopped the action due to listlessness (-_-)

i like your little implemented functions!
