Lamp Dimmer (Stepan Novotill) - This must generate an
awfull lot of RFI without a choke! The house wiring supplies the di/dt
limiting. This is a CHEAP….. [Reverse engineered schematic by

Lantern Flasher/Dimmer - The electronic lantern control
circuit adds high-efficiency dimming and flashing to an existing
battery-powered lantern or flashlight or to a custom design.
For the car it makes a great lamp..... [Tony van Roon's circuit] |

Lantern Flasher/Dimmer (techlib) - The electronic lantern
control circuit (fig. 1) adds high-efficiency dimming and flashing
to an existing battery-powered lantern or flashlight or to a custom
design. For the car it makes a great lamp for changing a flat tire,
back seat reading or emergency engine work.....(circuit / schematic
design added 6/06) |

Lantern Flasher/Dimmer (tomzi.geo) - Basically a
high-efficiency dimmer, but can also be used as a flasher. In dimmer
mode, the LM358 (dual op-amp) is wired to send pulses at a constant
frequency. By adjusting the width of these pulses, brightness of the
bulb is controlled. In flasher mode, the same
potentiometer.....(added 10/05) |

LED dimmer uses only two lines - 21-Mar-02 Issue of EDN The
circuit in Figure 1provides 32 steps of brightness control-from 0 to 100%-for a
backlight or instrument panel, using just two general-purpose-microprocessor
signals. In addition, the circuit requires little board space, because it uses
only three SOT-23s and one µMax package..... [Design Idea by Jerry Wasinger,

Light Dimmer Circuit with 0 to 10 Volt Input - This is a simple dimmer
circuit that can be controlled with0 -10 VDC. It is designed for 110-Volt AC.

Linear Constant Current LED Lamp Dimmer - This circuits drives24 white
light LEDs with an adjustable constant current. (added 6/06) |

Low side PWM Motor/Light Controller - These two schematics are
variations on another PWM circuit that I designed. The diagrams are for 12V
operation only and there are high side (common ground) and low side (common
+12V) versions. The low side version of the circuit uses an N Channel FET, the
high side version of the circuit uses a P Channel FET. N Channel devices tend to
handle more current than P Channel devices, they are also less expensive. The
high side version of the circuit is useful when one side of the load has to be
grounded..... [Circuit Designed by G. Forrest Cook] |

Low Voltage Light Dimmer - A light dimmer is a means of controlling
the "brightness" level of a lamp, in this application we will use a555 Timer to
control the brightness level of a low voltage incandescent bulb of up to
60-Watts. For the light dimmer to work the555 Timer is configured as a "variable
cycle", astable oscillator running some where around300 Hz...... |
