irab88's 1993 PickUp Build-Up Thread

two separate circuits, yes. the "location" i'm looking for is for where to mount the led's in the cab. i don't want to just drill a hole anywhere, so i'm going to see if there's an open indication slot on the gauge cluster. the size of the sensor is tiny, and mounted on the fan cord, it's only about an inch in every direction.
there are basically 5 parts to this circuit: sensor, pull-up resistor, led, ferrite choke, and wire. nothing else

you could find a location for the LED that will light an area indirectly, like under the dash aimed at your feet. I say this because you don't want an LED focused at your face, it will be annoying. For now mine lives under my radio, and illuminates the floor, and filler panel that is perforated aluminum and lexan. I sanded the lexan to give it a frosted appearance , but still let light thru. I'd like to use two different color LED for hi and lo speed, so it would be easy to see the difference.
I was going to drill a hole, but the LED kicking on and off is distracting, the LED is simply for glancing at to make sure it's kicking on when it should, after a while i don't even realize its on.

Makes no difference to me, i was going to get a single bi, but i am actually running two LEDs cuz i couldn't find the bi i bought.
I can paypal you, just let me know.

total cost of the circuit will be less than the shipping to get it
here's the parts list:
i have wire at home, i'll check to see if i have enough. otherwise, it's pretty cheap.

custom ammeter, light-out indicator, security system, and i'm sure there's more
one thing i realized with the circuit: if the fan kicks on while driving down the freeway, but the air is already turning the fan, this circuit might not sense it. i'll play around with that.
aaand the price up there is too high, actually. i have 2 led's in there for one circuit, so the cost should be $2.25
