TRIAC Light Dimmer
TRIAC Light Dimmer
October 12, 2010

This little circuit can be used to dim lights up to about 350 watts. It uses a simple, standard TRIAC circuit that, in my expirience, generates very little heat. Please note that this circuit cannot... [more]

Triple Stroboscope
Triple Stroboscope
October 12, 2010

This circuit enables observation of movement between other stroboscopes. Generation of rectangular signal is based on NE555. This circuit requires a low power supply that is made from a simple transformer TR1, traditional rectifier bridge... [more]

Two-wire Lamp Flasher
Two-wire Lamp Flasher
October 12, 2010

This circuit has been designed to provide that continuous light lamps already wired into a circuit, become flashing. Simply insert the circuit between existing lamp and negative supply. Especially suited for car or panel pilot... [more]

12 Stage Neon Sequencer (NE-2 / NE-51)
12 Stage Neon Sequencer (NE-2 / NE-51)
October 4, 2010

This circuit is similar to the LED clock using 12 neon indicator lamps instead of LEDs. It operates from 2 high capacity ni-cad cells (2.5 volts) which keep it going for a couple weeks. High... [more]

Automatic Low-Power Emergancy Light
Automatic Low-Power Emergancy Light
October 3, 2010

Here is a white-LED-based emergency light that offers the following advantages. 1-It is highly bright due to the use of white LEDs. 2-The light turns on automatically when mains supply fails, and turns off when... [more]

Fading Leds Circuit Diagram
Fading Leds Circuit Diagram
October 3, 2010

This circuit operates two LED strips in pulsing mode, i.e. one LED strip goes from off state, lights up gradually, then dims gradually, etc. while the other LED strip does the contrary. Each strip can... [more]

Flashing Eyes
Flashing Eyes
October 3, 2010

This circuit was purposely designed as a funny Halloween gadget. It should be placed to the rear of a badge or pin bearing a typical Halloween character image, e.g. a pumpkin, skull, black cat, witch,... [more]

High-intensity LED Warning Flasher
High-intensity LED Warning Flasher
October 3, 2010

This circuit was designed as a warning flasher to alert road users to dangerous situations in the dark. Alternatively, it can act as a bicycle light (subject to traffic regulations and legislation). White LEDs only... [more]

LED or Lamp Pulsar Circuit
LED or Lamp Pulsar Circuit
October 2, 2010

This circuit operates a LED in pulsing mode, i.e. the LED goes from off state, lights up gradually, then dims gradually, etc. This operation mode is obtained by a triangular wave generator formed by two... [more]
