Internet Radio with Raspberry Pi from Nico_J on Vimeo.
Using _Marcel_’s Instrcuctable Nico made this lovely version of a Raspberry Pi Radio with a CNC router:
Thanks _Marcel_ for this instructable. It gave me the inspiration to make a retro look radio.
I modified the software a bit to allow the use of manual tone and volume control, a status indication by means of a three color LED and a different rotary encoder.
Initially I powered the power amp from a 12 V switch mode power supply and converted the 12V to 5 V by means of a DC/DC converter.
This proved to be a very noisy solution and I had to seperate 12V from 5V by using 2 PSUs. My first Power Amp was a ready made module from Aliexpress using a TDA7297 which proved not to be capable of driving 4 Ohm speakers.
I therefore had to make an alternative using a TDA2004 which works perfectly now.
