nope just plan it

that would be a no, although i think i might have done something similar, thanks anyway, I've spoken to a friend n they haven't used any formulas so i might give it a miss thanks for you time anywayz

any wat? nope don't think so (if i have i don't no it by that word) sorry

here is the task; Design a labatory experiment to investigate how the range of a projected object depends on the angle of projectory and find the optimum angle i was thinking of getting dome tubing, and ataching a preasurises CO2 canister (fire extingiser basicaly), and put something in...

sam ur 1000% percent right! you people are a god send, I've been searching the net for about an hour (i know that isn't very long) but I've stubbled across you community here and I've got just about all the info i need from you! a lot of examining boards seem to like the topic of IR and distance...

just need to know about infrared sources and the output of infrared detectors I think it's volts but not sure any links or info is welcome thanks rob
