    An electric stove when I was in grade school.

    And a simple light bulb + switch project (where I kinda messed up the wiring and caused the circuit breaker to trip).

    Hmmm... i think madami akong projects nung highschool like the ff:

    - dancing LED lights
    - power supply... i think it can supply up to 16V of power. im still using it to power my old mp3 player pagwala nang battery.
    - AM radio
    - amplifier... i forgot na din kung anong klaseng amplifier yun basta pampaganda ng sound ng audio system. hehehe!

    and many more... ^_^
