DIY Ferris Bueller Intercom System
Using an Atmel microcontroller, this DIYer created his own Ferris Bueller “I’m not able to come to the door right now” intercom system. Code, schematic, and MP3′s are all available, making the project simple to replicate. It’s quite a bit more complex than it needs to be really – seems like it could be significantly condensed using the Arduino. Although, the same effect could easily be created using it.
