OMG. I love this thread, since I am currently in my first year of E&E engineering.

currently got project (actually a year two project), where we have to create a circuit. my group will do the mosquito repeller (using ultrasonic). but we need to modify the circuit (in order to get good marks). still thinking about how to modify it. actully, none of my group members are good in modifying/designing circuit. neither do i. i bought breadboard etc to do some self-experimentation at home in future ( after i settle all the projects )

btw, did you guys know where can i get moon shaped LED and other wacky-wakcky shapes LED? been hunting for them a few weeks already.
