The MAX9926 is probably the best VR decoder ASIC on the market today. Good choice.

Thats what my research has led me to believe. I think you said something along the lines if the noise rejection defies physics?

I had 3 of those chips built onto DIP conversion boards by some company in canada for pretty cheap for a different project. I think it came out to like $20 per + shipping. Mainly because I really really didnt feel like dealing with a surface mount chip on a protoboard.

Indeed we use the MAX9926 in our ME221 ECUs - good for VR or even hall if the other side is left floating

chose pins and IC assembled from up top, and put in the digikey part number of the chip you want and presto it'll be at your door in like 2 weeks.

I've purchased their adapter boards in the bast (though I did my own assembly, because I'm a bad-*** with a soldering iron.) Good-quality parts at an excellent price.

Surface-mount isn't hard to do IF you have the right tools and are experienced with general soldering work. A Radio-Shack iron isn't the right tool. In fact, my fancy Weller is just barely adequate even with the expensive tip in it. When I worked at Harris, I took all my surface-mount work into the lab and used the $500 Metcal iron and the Bousch & Lomb stereomicroscope.

Moral: you can do it yourself if you try. But if you can pay someone else $6 to do it for you with the right tools, go that route.

Just to be sure, this is just sine to square, right? No front/rear comparison, something that could be fed to a dinosaur ms2 as "knock."

What is a 3.0 board? Will a Ms3 daughterboard thing work in place of my ms2 microsquirt?

I need to buy a ms3 and sell this diypnp, should have done ms3 from the start...

So many other things need money spent on them...

I still need a rollbar, and new tires.

Who wants to buy my diypnp, lol
