Sunrise Clock

       

A hand-made alarm clock that uses slowly increasing light and sound to wake you up.

Project Features

Built for an Arduino Pro Mini using the fantastic Arduino Che Cosa framework.

• White LED Matrix Display shows Time and Menus    

•        IR recevier, Apple Remote (or others) for control

•        TinyRTC Real-Time Clock (for time and alarms, battery-backup)

•        Cheap chinese MP3 Player for Wakeup Sound

•        Audio Volume Control (via LM1972)

•        Audio Switch (external Jack input, internal MP3)

•        2 x 3W Amplifier (PAM8403)

•        2-way Speaker

•        Subwoofer included in glass sphere

•        2x USB Charger 5V @ 1.5A

•        USB Flash / Debug Port <--> FTDI <--> Arduino

•                     Cree LMH2 850-lumen LED with sunset dimming

• old Apple iBook G4 Power Supply @24.8V, 1.8A for Power

Under-the-Hood Impressions

Setup and Cabling

DIY PCB for Audio Volume Control. All cabling and setup still in prototype stage. I'm thinking about doing a small PCB for all the components... Audio Quality could certainly be improved with properly shielded 4-layer PCB.

Audio Hardware

Subwoofer Speaker uses the Glass Sphere (from an IKEA Fado Lamp) as Body. Sealing of Glass Sphere using custom Silicone Ring. No apsorptive material in sphere yet... might improve frequency response!
