Could be a fun MAKE project…“Cuckoo IP is a voice messaging system. The clock’s answer phone can be dialled from mobile or landline. Leave a voice message, select a time for the delivery of it. At that time, the cuckoo will emerge from the clock and broadcast your message. The device uses networking protocols to communicate with a server. Every minute, the clock asks the server if there’s any message for that time-slot and request the sound file.” Link.
