Homemade LED lamp

!±8± Homemade LED lamp

12x10mm LEDs connected in a parallel circuit. Resistor value was guess and check as I did not know the voltage drop per LED. Just found one that allowed the lights to be as bright as possible without getting warm. Using 9v DC 850mA cord from old Casio keyboard as power source. The projection is coming from a simple magnifying glass.
