FBD38

Beware is not properly done, there is serious risks of explosion (see what happen to apple these days). You need also to control the Battery temperature, above 50

I am interested by solar cell projects (equipment that are "sun" sufficient). Is there a specific place for these type of projects, is there other sites more concerned by solar electronics ? Typically, I've developed a "solar mailbox" using a PIC 16F628 and 3 AA NiMH cell battery powered by a solar polysilicon cell. This allows to drive the 3 digit (composed of about 60 white leds) to display the house number. Is there a place where I can put this project on-line ? Let me know where. I am also interested to work on other projects using solar cell, is there a dedicated forum ? Regards,
