I have build a fan controller with digital sensor from -50 to 150 Celsius.
It have 4 programmable outputs and also the ability to run after ignition off for programmable time.

here some pics

are you using a basic stamp or something like a propeller chip for this?

 

I am using avr mc with assembly

 

Is it on/off or pwm?

 

where did you get the kit or pcb?

 

It is not kit it is made all by me.
Pwm? No. single on off to trigger the oem relay.

 

I like it!

I started playing with Atmel (via Arduino) micro-controllers a couple of years ago. I build an LED cube followed by an AC condenser fan controller for my 02 Avalanche.

I've been thinking of making a controller to lower my FD (driver or passenger) window half an inch when hatch opens and then roll the window back up when my hatch is shut. My hatch is nearly impossible to shut / latch when the windows are rolled up.

If I could stop tunning my BNRs for a couple of days maybe I would make it. LOL ...

This for window is in near future after fan controller it is time to finish portable compression sensor

 

nice. I like the controller could you post some schematics or parts you used? im interested in doing this my self

 

The parts is the easy way and yes i can list them.
But i would not post my code for mc.

 

could you email me the code?
