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 design which
exhibits hysterisys at dim settings. Not everything made and sold to the public is top
notch. (added 2/05) |

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 for changing
a flat tire, back seat reading or emergency engine work. The flasher mode is
useful for warning other drivers of your troubles and it may be adjusted ,... (Tony

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. The flasher mode is useful for
warning other drivers....(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 - 03/21/02 EDN-Design Ideas: 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 Max
package.....(design idea added 1/05) |

|
Light Controller Variations - Diagrams are for12V operation and there are high
side (common ground) and low side (common +12V) versions (added 5/02) |
|
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. (added 4/02) |
|
Linear Constant Current LED Lamp Dimmer - This circuits drives24 white light LEDs
with an adjustable constant current. (added 6/06) |
|
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. (added 7/03) |

PIC 16c63 MIDI Controlled Light Dimmer - four channel dimmer controlable using
MIDI interface, operates at110-Volt AC, design can be modified to use standard baud
rates, and the RS-232 Electrical interface (added 6/07) |

PWM Motor Speed Controller/DC Light
Dimmer - DC Light Dimmer using a LM324 IC (circuit / schematic design added 6/06) |
|
PWM Motor/Light Controller - 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 add 6/07) |
