The clock is using a housing from TEKO (D14).
3D-printed parts are used to fix the speaker, and to hold the display. Another part is hiding the metallic parts on the back. A distance holder and caps for the rotary encoders are other 3d-printed parts.
Features of the diy clock:
capacitive power supply to reduce electric smog
big and efficient 1.2" 4-digit 7-segment display (I2C)
Teensy 3.1 board with 12 Bit DAC (SD-card wav player) and internal Real Time Clock (RTC)
efficient I2C class D amplifier (89% efficient with 8Ω speaker at 1.5 Watt)
DCF77 receiver
two rotary Encoder with switch for easy and intuitive control
state machine programmed with arduino (teensyduino) for easy changments in the software
