Circuits I've decided to start a page where we can share circuit ideas. For my DTMF Decoder circuits, click here. Help!Anyone have an MC14506 AND-OR-INVERT IC? Please email me if you do.Night LightThis circuit turns a light on when it gets dark. Good for hallway footlighting, night light, security light, etc. I designed this circuit to run off a 12V battery that I charge with solar panels. It will run from any 12V source however. The circuit and further descriptions can be downloaded in Word 2000 format by clicking here. Or click here to view as a web page (click your "back" button to return here after). |
