[Gmecm] sound card crankshaft signal generator

[Darrin Garrett]

I have written some software that uses a sound card from a PC (Win XP ) to generate 24x (LS1) and 24x (northstar) crank signals.  This signal levels are not correct but the timing and edges seem accurate.  Its has a fairly easy to use GUI.  I was going to add the DIS output too, but have not done this yet.  All signals will need to be conditioned with external opamp circuits, which I have not done yet and don?t know when I will get to it.   Especially the reluctant signal types, ( DIS and Northstar 24x).  I am also adding a feature that will allow you to record the output and play it back.  And one more thing all of this is useless unless there is a synchronized cam single supplied as well, which I hope to get to with the addition of a second < $20 external or internal sound card.  I do not have an LS1 or DIS engine/system so they are of no use to me, but thought some of you could use this on your engine simulation bench, for free of course when it is some what finished. 
 Any takers?
