> I think the problem is there are not enough current to > drive the relay. oops, posted the wrong schematic... mine was still wrong, but I did have the transistor... The one I ment to post is http://www.dpicts.com/Tiny15L-LaserDetector-2.jpg which has the NPN, but I hooked up the transistor the way it is shown on page 3-2 of the STK500 manual... so after everyones advice I have changed the schematic to http://www.dpicts.com/Tiny15L-LaserDetector-fixed.jpg I didn't add the diode as someone suggested b/c I am actually using a solid- state relay (an Laa110)... If someone could confirm my corrected schematic I would be very greatfull. Thanks again, Daniel KC9DAG
