Build your own VR conditioner
#48
I don't have any experience with surface mount components and pretty limited experience with soldering. I do a lot of clusterfucky stuff with wiring, not so much with circuit boards and 0 with SMCs. I learned to do some through hole components at a summer camp when I was 12 and in college. I've got 3 chances to get it right, hopefully one sticks.

I thought that at least the NB sensors already generate a square wave. Never checked though. Not sure if it's 12V or 5V. In any case, just running it through a double inverter should get a nice square 5V signal. I'm not even sure why we go through all the signal conditioning trouble with the MS, other than the signal conditioning circuits are already there when following the assembly instructions, so we may as well use them.
Somebody who actually scoped the signals and understands what the MS conditioning circuitry does, please correct me!

And on the soldering:
I'm too old and have bad eyes, shaky hands and all that good stuff. Trying to hand-solder 0402 components is totally frustrating under those conditions.
So for SMD I usually get a stencil from oshstencils. Spread some paste, add components under a $25 Ebay microscope, bake it in the old toaster-oven for a few minutes and Bob's your uncle.

Doh!
I was referring to the CAM and CRANK sensors. Didn't even consider ABS and Speed.
Never had any issues with my speed sensor though. Seems to be reading accurately and reliably. My '99 doesn't have ABS, so that's pointless to check.
