    Something I found while looking for a Time delay circuit earlier.. might come in handy?


    Car Tachometer
    The timer receives pulses from the distributor points. Meter M receives a calibrated current thru R 6 when the timer output is high. After time-out, the meter receives no current for that part of the duty cycle. Integration of the variable duty cycle by the meter movement provides a visible indication of engine speed.

    Oooh, looks interesting, Twizted I'm gonna have to take a look inside my current tach at the little circuit that's there...it's a couple of resistors/capacitors and a small 8pin chip...let's see if it's one of these circuits

    Will post a pic of it soon

    I'm working on a similar stuff. I'm using Pic Microcontroller to get data from the car and send them to the computer via serial port. I have some of them working. For the PC part I'm using a program call "easy control". You can creat all different types of gauges and controls with this program. Here's the link:http://www.easyvitools.com/index.html. I try posting some picture later when I get home.

    I bet it is... 555 timer chips are 8pin..
    I am looking forward to your progress on this project... Mine will be going in a 87 Nissan Pulsar/Exa so I would like to be able to get readouts from it...

    Unless there is anything on the back of it...that's all the markings on the chip

    Confused,


    Very unlikely you will see a marking at the back. Does it still work? Theres a crack on the 3rd and 4th capacitors from the left
