Raspberry-Pi solar-powered FTP server
David Hayward over at CNET UK has posted an article describing how he designed a solar powered FTP server based on the R-Pi. The additional hardware consists of a solar cell array and 4 NiMH batteries. The solar panel is by Cottonpickers, but you could use any appropriately rated panel. (Be sure to include appropriate […]
Open source solar data acquisition system PCBs
Arup got some PCBs made by Seeed of the open-source data acquisition system he designed. The system uses solar panels, and rechargeable batteries for power. An ATmega32 microcontroller reads, and stores data onto a SD flash card. Data ca also be viewed via a character LCD. Via the forum.
Solar powered Arduino sun tracker
Solar panels, hot glue, old CDs, an Arduino, a servo, resistors and LDRs, that’s what luwe1 used to build this solar tracker. He had some little solar panels laying around and wanted to see if they would power the Arduino. They did. So, I wanted to see if I could make a sun tracking circuit […]
