My CarPC continued...

 

Power Supply:

As my pc can be directly connected with my car battery but I made this circuit for clean and regulated 12V. It will sure protect my CPU with power spikes and over/under voltage.


 

Remote Control Switch:

Serial Switch software has been used for voice command to the computer,

This module is comprised basically two sections ; first the software part and second hardware part that use serial port of the PC to sense signal when the push button is pressed.

Software always runs in memory showing at task bar near clock, and listening serial port for +ve voltage.

Hardware Part is little tricky as I need a switch to inject a +ve voltage signal to one of the pin of serial port, so I got a RC car circuit (yea wireless switch... isn't cool).

This circuit basically inject a small voltage to the pin no. 7 from pin 6, initially I was thinking to put a relay for that purpose but after some checking I found it is safe to provide Potential difference to pin 7 through a resistor.


Microphone Preamplifier:

This is to make my microphone more sensitive so I don't have to yell in my car or to put microphone in my mouth... I don't eat microphones....
