YouTuber Kim Wall made this awesome deaf alarm clock using a Raspberry Pi.
Raspberry Pi based vibrating alarm clock, in an 1980s Bond Villain style. Control is via the LCD and buttons, and also over the network via an IRC bot interface. Fire alerter and vibrating pad are FireAngel Wi-Safe2, which continues to operate if the clock fails.
The clock is also a GPS-based Stratum 1 network time server, and is able to maintain accurate time without a working network connection.
The clock will connect with other modules over the network for doorbell, telephone alerter, central heating control and various other features.
Power is supplied at 48V in a IEEE 802.3af style, but as the Raspberry Pi lacks POE breakout, the passive POE dongle is required.
