    I know this thread is a little old, but I'm trying to do the same thing. Momanz - if you're still around - where did you get the MAX chip, the adapter, and the thermistors?

    Thanks,
    Dan

    Dan, I got the chip from maxim as a sample. The adapter came from the link below and the sensor is actually a transistor (2N3904 NPN) not a thirmistor. The transistor is a fairly common one that you can find at most electronics stores or you can order them from glitchbuster.com shipping is under $2 for most orders.

    adapter ==> http://www.epboard.com/eproducts/pro...OPtoDIPAdapter

    If you've ever etched a cu board to create a custom PCB you don't need to buy the adapter. Be sure to use the staples inkjet paper as your transfer media. Search, there's a link somewhere on the site that will take you to a step by step instructions on etching cu boards.

    Good luck.

    Bah every one has to go writing there code in picbasic. Tisk Tisk are there no people out there that like ASM? At any rate I don't think I will have any problems writing some asm to make the sensor. If any one is interested I will release source when I'm done.

    I'm also going to see about using some of the A/D converters on the 16f88 to suport a few thermoresisters (they can handle very high temps) for monitoring exhast temps.
