Soft starter used to save plastic gears of modern cheap tools by applying less initial force. Angle grinder, Miter saw and other funny jumping during power on universal motor equipment will be happy.
* ZC detectors to syncronize TRIAC timings and detect power-on switch status on tool
* TRIAC to soft start motor from 30% to 100% power
* NOTE: Do not use smart tools with speed control...
Triac based Indecent lamp dimmer is a simple circuit and it doesn’t requires additional power supply, works directly with 110V AC or 230V AC.
It is a low cost dimmer circuit for adjusting the light brightness of incandescent, Halogen Lamp, Light Bulb load up to 250 W.
– Input supply: 230 VAC or 110 VAC
– Output: 250 W
– Triac controlled
– On board Potentiometer for adjusting level
– Power Batte...
AC Fan Seed Controller with DHT22 (or DHT11) Temp sensor and LCD Display of Temp. UART or I2C options for 16x2 LCD diplay shown. Uses External 240V to 12V DC PSU to provide power to the Arduino Vin pin and the 5V output from the Arduino to provide power for the DHT22 and ZC Probe.
Demonstrating the effect of dv/dt turn-on in a Thyristor.
For a Thyristor or SCR in the non-conducting state -
even with the gate tied to the cathode - as the rate
of change of voltage (dv/dt) across the anode and
cathode terminals exceeds the datasheet specified
maximum value (in this case 30V/us), the device will
A similar effect occurs in Diacs and Triacs.

Apesar do nome estranho, o projeto possui as funcionalidades do título.
A primeira é um "**caçador de vampiros**" de energia (baseado no projeto TOMADA INTELIGENTE do Br-Arduino.org com uso do Attiny85), que consiste em eliminar o consumo de energia dos equipamentos em espera (stand by). Diferente do Tomada Inteligente, este não faz uso de uma régua, mas sim de uma caixa que seria o "interrupt...
