Flickering Fire Light - LED or Bulb flicker shimmer randomly like candle flame or fire
Photo Flashes at 1.5 volts
Color Organ Light - Flashes coloured christmas type lightbulbs to music. This circuit works REALLY well. Notice how it will fire even in complete silence. This provides a sort of automatic gain control.
Delayed Off Light Switch - Rated for use with incadescent loads. This is an unusual design in that it uses plain metal gate CMOS logic instead of the usual PIC or a custom chip. The 22uF capacitor charges up during one half of the ac cycle, and supplies trigger current to the triac on both halves.

1.5 Volt Strobo with a Kodak Max Disposable Camera. How to modify a Kodak Max Disposable Camera Flash Circuit and build a 1.5 volt supply STROBO. (Yes! just using a 1.5 volt AA alkaline battery!!)
Laser Link / Transmitting audio or data over a laser beam (105 kHz carrier) !!!
Keychain Laser Driver / circuit description
Light Chaser - A Modified MOVIT Robot: it seeks the brightest light and runs towards it! It has two motors (left & right) in order to make the turns; on top two light sensors (photodiodes) separated by a PC board in order to simulate "a nose".
Rechargeable Led Flashlight. This is the project of rechargeable flashlight using a high intensity red Jumbo Led. The main idea is to have a moderate source of light that will be ever at hand, without batteries to replace or light bulbs to change. It may be left plugged in the 110 vac wall outlet, ready for use.
