Efficient alarm clock with low electromagnetic radiation, big display and music player

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)
