1200 Watt AC Dimmer by Triac Q4006LT

This is Power AC Dimmer 1200 watt size. It is use a triac Q4006LT. Friends ever tour is the foreign land has and to ever reach rest a hotel. On bed head has will head bed fire decorates. It has a button opens-close and a button controls the brightness with the equipment this/these be AC Dimmerfollow our circuit can fine to decorate. The VR1 for control the light besides when friends apply TRUE work. The Q1 -Q4006LT , should hold heat sink with and should be careful specially prohibit catch one ( part ) which part in the circuit , because read will bump against the electricity can suck. I hopes this circuit , friends can induce apply be AC Dimmer with electric other appliances bump against emphasize kind coil heat equipment , be lucky please yes.

AC Dimmer for Lamp 6.3V

This the circuit AC dimmer low voltage For lamp 6V. While this friends may don’t see the advantage of this circuit. But I thinks first step advantage be something get learn the work of Triac. And have tall safety , because of use AC Low Voltage. Which the work is simple be The UJT Q1 will do the frequency give Triac work or make Lamp the bright. By have work rate of Triac can control with R1 or Be something dimmer there. You will may apply with the size Voltage the other all right. The Q1 use UJT – 2N4891 or other. A friend may gain an advantage from AC Dimmer for Lamp 6V , please sir.

AC Load Line Power Flasher by SCR

Here is an unusual flasher circuit for 120VAC loads. The circuit is similar to the two-transistor flasher seen in several circuits in techlib.com except that an SCR is used.
A little circuit trick is hiding in the selection of the 0.1uF capacitor in series with the 1k resistor. When the SCR is off, this capacitor smoothes the ripple from the bridge sufficiently for the transistor flasher circuitry to work properly but when the SCR turns on, the capacitor immediately discharges and will not provide enough current to keep the SCR on.
