LED Clock with Timer & Solar Panel
Regulator - This is a combination digital clock timer
and solar panel charge controller used to maintain a deep cycle battery from a solar panel. The timer output
is used to control a 12 volt load for a 32 minute time interval each day. Start time is set using 9 dip
switches and ends 32 minutes later. The 32 minute duration is set by selecting the 5th bit (2^5 = 32) of a
4040 binary counter (pin 2). The timer also has a manual toggle switch so the load can be manually switched
on or off and automatically shuts off after 32 minutes. . . [Bill Bowden, designer]
