Simon built a solar powered Arduino FM receiver. Using a solar panel to charge the batteries, this Arduino controlled device can work without the need to recharge. A SI4073 FM tuner ICs output is connected to a TDA7051 integrated amplifier, while the Arudino controls the channel selection of the FM tuner. There is a multi-position switch used to select 12 pre-saved stations. Station, volume, and battery charge information is available over a 16×2 LCD screen. The schematic and source code are available.
