Light-Laser-LED
That Section include a load of circuits and projects that use LEDs/lasers/Bulbs. Find from laser diodes drivers, light sensing circuits, led circuits, Xenon lights, and more. 100s of LED/laser/Light circuits for every hobbyist, technician, student, and design professional. An nice reference tool which includes lots of LED/laser/Light circuits. look at these circuit ideas, some of them may need some modification if they are to work as advertised. Ideas along with pretty good descriptions for each circuit.
