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.
Dimmer based on ESP12-E (ESP8266). You can control it using phisical switches or push buttons or throw network. Arduino scketch will be available soon.

Soft starter for Angle grinder, Miter saw and other funny jumping during power on universal motor equipment.
Also it saves plastic gears applying less force during slow starting.
TRIAC used to soft start motor from 30% to 100% power, then relay used to feed full mains sine wave to motor. Also it supports soft stop with start/stop buttons.
Do not apply load to motor before relay latching to pre...
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...
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
turn on.
A similar effect occurs in Diacs and Triacs.
To run t...
