This triac-based 220V AC motor speed controller circuit is designed for controlling the speed of small household motors like drill machines. The speed of the motor can be controlled by changing the setting of P1. The setting of P1 determines the phase of the.... -
This flashing light circuit uses triacs to generate an intermittent light with variable frequency. Additional components are the D1 diode and semi adjustab.... -
This time delay switch circuit is useful to switch on an AC load such as lamps after the delay of three minutes. This protects the load from inrush current and transients at power on which may be detrimental to the device. The time delay switch is directly.... -
Light Sensitive Staircase Switch with Triac , Operation of the third circuit is much similar except that it has photo sensitivity. The circuit is shown in Schematic When there is no sufficient l.... -
A few people have requested some clarification about calculating resistor values for the triac circuit. If I`m doing this correctly it might prove helpful in adapting the Sous Vader for custom builds. If I`m wrong, hopefully somebody will point out my.... -
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 be used with fluorescent lights... -
In order to switch some floodlights by my Arduino, the small switch circuits I built around a 39mf22 were just not man enough to handle the current ne.... -
LEDs simply react a lot faster than conventional bulbs Light dimmers for common bulb based lighting have been around for ages. The most common implementation of such.... -
Controlling room lighting using computer. I bought some triacs and opto couplers to do this. I drew the schematic and built a prototype. Everything worked well. We cannot see it on the pictures, but there is a cable going out of the box that plugs in the PC.... -
In the event of combustible gas, the conductance of TGS308 gas sensor increases, and the voltage is removed through the potentiometer RP1 slide point, and its value is increased from normal 3V rms to 20V. This elevated voltage is added to transistor VT1.... -
In order to solve the lag and light transition phenomena, it can use the Triac dimming light circuit shown in the figure with dual time constant. The circuit increases R3, C2 resistor-capacitor network, and the reducing charge on capacitor C1 can get.... -
This solid state relay circuit uses 120 volts household mains and should only be attempted by someone that has the knowledge and skills to safely construct such a project. Otherwise personal injury and or property damage could result... -
The TRIAC is a three-terminal device similar in construction and operation to the SCR. The TRIAC controls and conducts current flow during both alternations of an ac cycle, instead of only one. The schematic symbols for the SCR and the TRIAC are compared in.... -
Triac temperature-sensitive heater control. This circuit can be modified as shown to control a motor with a constant load. As shown the circuit is for heating applications but can be used for cooling by interchanging RT and R2 (courtesy Motorola.... -
