Arduino + AD9850 30MHZ DDS Signal Generator In 12$

An Precession Signal generator is very easy and affordable make using an arduino and dds synthesizer (ad9850) . Its World’s first smallest portable signal generator build. You can make decent 0 -30 MHZ frequency Signal generator only in 12$ . If you are pro over clocker then 40MHZ in same price . AD9850 works on dds (direct digital synthesis ) which can generate analog waveforms with digital input , here i used arduino pro mini to control dds board and Hitachi hd 44780 lcd display (16×2 lcd) to display current frequency and chage steps.”
