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....
LED Current Regulator - Here is a circuit that will allow LED's to glow at a constant brightness throughout battery life or varying power supply voltage.  This circuits is capable of saturating, allowing the battery voltage to get within 0.3 volts of the LED voltage before the LEDs start to dim.  This is far superior to just using a current limiting resistor.
