good intro on why proper grounding is important

Thanks A LOT for posting this link Dave. Very interesting and relevant info for one of my projects.

Hi Jim Very curious info Do you have some good references so i can get up to speed on that? (not the X-tau in general, which is easy to find, but rather intricacies of applying it for the scenarios you describe) Also please elaborate more on "interleaved with AFR scheme" By tracking AFR, i...

to OP: if you feel adventurous, why not get into simple microcontrollers (PIC, Atmel, freescale...), get a dev board with proto area (for relays and extra circuitry needed) and hook it up to the PC through Serial port or USB if available. This is of course the long way to solve your 'problem at hand...

Congratulations also on being our first female member! (that I know of) Most impressive :-) INDEED! programmable logic + car stuff + female = your husband is very very very lucky guy! ;) hit up some cpld/fpga forums, people love the digilent stuff - chances are their cable will fit the application.

what Fred said see my sig for links. I ended up not touching the uC emulator/simulator. I figured it would be a much better idea to do the black box testing + automated experimenting/flexible test cases (the way freeesim was conceived to do it) rather than white-box testing, i.e the uC emulator way....

crap, my bad

i was happy nontheless as IMO it is/was step in the right direction

I am very happy that you've finally decided to use the non-flat hierarchy ;) , i've heard about that freemind tool before. I would also advise not to mix the implementation specific lingo with that of abstract design blocks. Work out the non-linear structure of abstract blocks (to the detail level u...

yea, we've chatted a bit with Fred and he's convinced me. I was just being prudent.

... or you will end up making many small sparks ;-) Fred. which is fine IMO as the flame front would have long left the spark spot at that time window, and only burned gases would remain at that spot. I have a feeling that small sparks is exactly what's going on during ion sensing the way manufactu...
