Platinenätzen

Ich habe zum ersten Mal eine Platine geätzt TraumWecker

max,

prototype: alarm clock

This is my first working prototype.
TraumWecker

  • plays mp3 music from sd memory card
  • shows status messages on an spi interfaced display
  • communicates via rs-232
  • receives and decodes the dcf-77 signal to drive a precise clock

rs-232

I got the RS-232 connection working. Nothing special, but from that helps a lot when debugging TraumWecker

uC programming

Worth an entry: The first day I have ever programmed a µ-controller myself. My aim was to build a digital alarm clock and this led me directly into the world of digital electronics. microcontroller_programming
