Wow 60.04 sec? that's incredible. did you medal?Everything in this thread has been covered in depth on the Photocell Bonus thread.....-
-what is and is not considered as a "photocell
-use of relays
-how to hook it all up and make it work.
Using a relay allows you to use pretty much whatever motor you want to. We're using a 12v computer cooling fan- (triggered by the photocell unit - )12v/20w bulb, photoresistor, 9v blue Radioshack relay) All powered by a 9.6v cordless drill battery. Works like a charm......
Box ran at 60.04 sec at Regionals yesterday.....
Oh, yeah; 1st. The other box (our Team 1) was 4th with the touch. We'd have been 1st and second. Both boxes were running within a couple tenths over 60 on Friday night....did you medal?
