Need to replace old broken defroster in my 240z but can not find any that are still working. Also needed to add switch to fog lights so figured willcombine the 2 plus add couple other functions to the controller and solve everything with single module to have following:
- defroster with auto shutoff 10 minutes
- fog switch dual filament one will be used as DRL.
auto shutoff with ignition swit...
A simple but flawed idea to make a fixed frequency variable duty cycle oscillator based on a 555
timer and using the push-pull output to drive the RC timing through two routing diodes, a pot and a
series resistor to limit the min/max duty cycle to something sensible at around 9%/91%.
If the diode drops were negligible and the 555 timer output pulled fully up to VCC and down to
<p>Using a 555 timer in <em>astable</em> mode as the control signal to a (4066) bilateral switch, whose input is an amplified audio signal (i.r., from an LM386). The output from the switch resembles tremolo.</p>

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...
