THE PROBLEM 'Walking/Bike-path light...........must be turned off !!! |
The Solution Expose the daylight sensor to some light @ night................and fool it!! |
CANNED LIGHT ! Build a can cover with a white light LED..........powered with two 1.5v AA batteries |
BASIC CIRCUIT Using this basic circuit design, the current draw is very low and the batteries will last........I have left the unit setup for almost one week and it still "killed" the light every night. |
COMPUTER CONTROLLED VIA X-10 PROGRAM The 3 vdc is provided by a small AC - DC X-former that is plugged into and X10 appliance module which is then turned on and off by the software program "X10 Active Home Professional." |
ELIMINATING THE CAN Recently I got brave and added something new....a small LED taped to the side of the light sensor. Power by a 3 vdc line running up the back side of the pole. The line is buired an runs to the observatory where it's controlled by the computer. I know this is not exactly approved or recommended, however, there is no direct connection electrically and it has no effect on the normal light operation. Only, when I fool the sensor to think it's day time. |
SMALL PROJECT, PLASTIC BOX Box for switch and batteries.................it's fairly water proof. |
MOUNT TO POLE Rigged to the end of a wooden pole. |
LIGHT KILLER IN PLACE The LED is properly mounted so it will line up the "sensor." |
