Home Camp: Nanode internet radio

Andrew’s internet radio based on a modified Nanode network platform. An AVR microcontroller uses an ENC28J60 ethernet chip to grab MP3 feeds from the net. Packets are stored in a ring buffer in a 32K serial SRAM chip. The buffer is fed to a VS1033 MP3 decoder chip. All of the chips are controlled from a single SPI hardware module in the AVR.

Station information is shown on an LCD, and various station can be set from a potentiometer-based dial. See a close-up of the control interface below.
