i hv also got a few questions for u guys!
1. do u not hv to heat sink an L.E.D or else it will blow?
2. do us use solidworks for ur designing/
also i dnt kno if it was sarcasm or wat but i noticed u didnt kno wat a PCB is. it is simply a Printed Circuit Board. i noticed also tht us use the perf boards. would it not be simpler to desing ur PCB nd then soldering nd all would be easier plus wit most PCB design progs like LiveWire u can see if ur circuit will wrk without hvin to make it first. i kno i said i dnt kno lot bout electronics but its more the robotics electronics nd all. i can actually use mostt electronics since in my school frm bout the age of 11 u hv to wrk wit them (jus makin simple stuff lik moisture sensors nd all at tht age tho). for my GCSE wrk i designed a circuit usin a 741 comparator tht took in a reading frm a thermistor nd then if the temp was above 80oC nothin happened but wen it dropped below the 741 activated a relay tht turned on any heatin device attached to it. oh btw it was a fancy heat sensor for my bearded dragons tank. i kno this is prob nufin to most of us but i thot i woud jus lets us kno tht i do kno a few wee things bout electronics!
also if sumone cud tell me how to add images i cud show u if u wanted
